I have a .net, C# Windows Form project. I'm using DevExpress 19.1. On my GridControl, I have conditional formatting for when a column is less than 0. I want the cell to be highlighted red when the value is less than 0, but it's not working. I've tried using an expression, a condition and value, applying to just a column, applying to the whole role, but I never get the highlighting to work. Can someone tell me what I'm doing wrong?
Here is how the rule looks liked in code:
gridFormatRule3.ApplyToRow = true;
gridFormatRule3.Column = this.colQuantityLeft;
gridFormatRule3.ColumnApplyTo = this.colQuantityLeft;
gridFormatRule3.Name = "Format0";
formatConditionRuleValue3.Appearance.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(255)))), ((int)(((byte)(128)))), ((int)(((byte)(128)))));
formatConditionRuleValue3.Appearance.Options.UseBackColor = true;
formatConditionRuleValue3.Condition = DevExpress.XtraEditors.FormatCondition.Less;
formatConditionRuleValue3.Expression = "[QuantityLeft] < 0";
formatConditionRuleValue3.Value1 = 0;
gridFormatRule3.Rule = formatConditionRuleValue3;
this.gvProducts.FormatRules.Add(gridFormatRule3);
Here's how I set the rules in the Designer:
Here's the output where you can see the value is less than 0 and the background color is not changed:
I see that you have only one row in the grid. The grid always has a focused row. The focused row appearance has a higher priority than conditional appearance. Disable the GridView.OptionsSelection.EnableAppearanceFocusedCell and GridView.OptionsSelection.EnableAppearanceFocusedRow properties to remove the focused row appearance.
this.gvProducts.OptionsSelection.EnableAppearanceFocusedCell = false;
this.gvProducts.OptionsSelection.EnableAppearanceFocusedRow = false;
Alternatively, set the FormatConditionRuleValue.Appearance.Options.HighPriority property to true.
formatConditionRuleValue3.Appearance.Options.HighPriority = true;
Set the AppearanceOptionsEx.HighPriority Property to True.

I have implemented bootstrap 4 data table 4 in angular 4 but not able to change or modify row color. row selection color and header color as well.
I am using the data table 4 example : https://github.com/afermon/angular-4-data-table-bootstrap-4
and in this examples demo go through the demo 1 of link: https://afermon.github.io/angular-4-data-table-bootstrap-4-demo/
Considering the below code snippet present in data-table-component-demo1.ts got by the Git project you downloaded:
<data-table id="persons-grid"
[header] = "false"
[multiSelect] = "false"
[substituteRows]="false"
[indexColumn]="false"
[items]="items"
[itemCount]="itemCount"
(reload)="reloadItems($event)"
[pagination]="false"
(rowClick)="rowClick($event)"
[rowColors] = "callBackForChangineRowColors"
>
<data-table-column
[property]="'name'"
[header]="'Name'"
[sortable]="true"
[styleClass]="someExplicitClass"
In this, we can assign the value 'someExplicitClass' to [styleClass] as shown above and define the class someExplicitClass in our data-table-component-demo1.css file as below:
:host /deep/ .someExplicitClass{
background-color:red;
}
However, this is applied to the whole of the DataColumn and not controllable on a granular level.
We can indirectly apply only background-color using the rowEvent variable available within the rowClick(rowEvent) function of 'data-table-component-demo1.ts'
On click of the row, I will set the selected property of the row to true and thereby will trigger the onRowSelectChanged function of table.component.ts file
Now, once I set [rowColors] value to "callBackForChangineRowColors" as shown above and make the below changes in my data-table-component-demo1.component.ts file:
rowClick(rowEvent) {
console.log('Clicked: ' + rowEvent.row.item.name);
rowEvent.row.selected = true;
}
callBackForChangineRowColors(a,b,c)
{
if(b.selected)
return 'blue';
}
This way, I will be able to apply the color of blue explicitly for the selected Row.
*I could'nt unfortunately find any solution to apply any other styles on a granular level using a readily available input parameter like [styleClass] for it wasnt exposed as an #Input within our column.component.ts. If anyone has an idea, please do help me know it.
I am using jQgrid version 4.6.0 (Free version) and trying to edit the height of textbox which gets rendered when we set editable: true in Column model. I want the textbox height to fit into complete grid cell.
Here the width of rendered textbox is fine and fits in the cell but how can I increase the height of textbox?
Trying to achieve:-
There are some trick which you can use. You can editoptions in the column defined something like
editoptions: { style: "height:40px;" }
It will set style attribute on the textbox creating during editing. I think that the trick will work for any editing mode which you will use.
UPDATED: One can do the following in case of usage cell editing:
afterEditCell: function (rowid, cellname, value, iRow, iCol) {
var tr = this.rows[iRow], h = $(tr).height(),
$input = $(tr.cells[iCol]).find("input"),
delta = $input.outerHeight() - $input.height();
$input.height(h - delta);
}
Inside of the most callbacks this will be initialized to the DOM of the <table> element (see here), which supports rows property to quick access to the row by rowIndex and the row (<tr>) supports cells array which can be used to get the cell by cell index. The rest of the code should be clear I hope.
I'm working in flex 4.0 and I have a data grid with three columns. The second column should display the selection(s) the user has made according to the these rules: if they selected only one name display a label with the name in that grid cell, if they chose more than one name then a drop down list should be displayed with a title "Multiple Selected" and the drop down when clicked will show all the names associated for that entry. Therefore the second column can have a mixture of labels and drop down lists. As an example the first entry they chose only one person, so for the first row the second column it shows a label with the person's name. Then in the second entry say they chose 2 names, the second row second column shows a drop down list with the two names in the drop down list. As you can see the second column has a label and a drop down list mixture. Note the selection process is not taking place in the datagrid, the information is simply being supplied by means of setting the dataprovider for the datagrid.
I figure it out you make a itemrenderer with both the label and the dropdown list but you disable one while enabling the other when the conditions are met. The only problem with this approach is I modify the width as well because the label comes first and pushes the drop down list to the right (even when it isn't visible and sometimes beyond the width of the column). So I adjust the widths of each component (setting one to 100% while the other is 0% depending on which is to be visible) but for some reason when I update the data it does not immediately change the cell, only if I click on the header does it change the width and the visibility. I think this is because the UI does not commit the width adjusts immediately? I know it's the width because if I comment out the width adjustments once my data gets updated you see the change right away in the datagrid. For instance if I have not chosen yet the names of my selection, the cell is blank. Then I make a selection of just one person then it shows right away the name in the cell using the label component. Then if I select another name the data gets updated again and you see in the data cell some space (this is the label thats invisible but has some text which causes some empty space) and the drop down list with the names of the ones selected and again it's an immediately effect I don't have to click on the grid to update it. Here's the code with the width adjustments uncommented:
protected function mxdatagriditemrenderer1_dataChangeHandler(event:FlexEvent):void
{
if(data.judgmentpart.JudgmentDebtors.length ==1)
{//display label and disable the dropdown list
lblData.visible = true;
lblData.enabled = true;
lblData.percentWidth = 100;
DDLdatagrid.visible = false;
DDLdatagrid.enabled = false;
DDLdatagrid.percentWidth = 0;
}
else if (data.judgmentpart.JudgmentDebtors.length >1)
{
lblData.visible = false;
lblData.enabled = false;
lblData.percentWidth = 0;
DDLdatagrid.visible = true;
DDLdatagrid.enabled = true;
DDLdatagrid.percentWidth = 100;
}
else
{
lblData.visible = false;
lblData.enabled = false;
lblData.percentWidth = 0;
DDLdatagrid.visible = false;
DDLdatagrid.enabled = false;
DDLdatagrid.percentWidth = 0;
}
}
protected function mxdatagriditemrenderer1_creationCompleteHandler(event:FlexEvent):void
{
lblData.visible = false;
lblData.enabled = false;
lblData.percentWidth = 0;
DDLdatagrid.visible = false;
DDLdatagrid.enabled = false;
DDLdatagrid.percentWidth = 0;
}
]]>
</fx:Script>
<s:HGroup width="100%" verticalAlign="middle">
<s:Label id="lblData" text="{data.judgmentpart.JudgmentDebtors}"
/>
<s:DropDownList id="DDLdatagrid" dataProvider="{data.judgmentpart.JudgmentDebtors}"/>
</s:HGroup>
</s:MXDataGridItemRenderer>
In my flex app I store the widths and visiblility of columns in an xml file. When the app loads it reads from the xml file and sets he columns values as applicable:
for(i = 0; i < columnsOrder.length; i++){
newOrder[i] = myDG.columns[Number(columnsOrder[i]) - 1];
newOrder[i].visible = (Number(columnsVisiblity[i]) == 1);
newOrder[i].width = Number(columnsWidth[i]);
}
myDG.columns = newOrder;
myDG.invalidateList();
The problem appears to be setting the visibility (it sets the visible field correctly but messes up the width)... I've tried setting it after setting the width (outside of the loop) and before the loop as well. It resizes the columns properly if I don't do anything with the visibility.
Any ideas?
Add an import statement at the top of your class file:
import mx.core.mx_internal;
Then remove using the mx_internal namespace, remove the owner of the column, change the width and then reasign the parent:
public static function resizeColumn(col:DataGridColumn, size:int):void
{
var owner:* = col.mx_internal::owner
col.mx_internal::owner = null;
col.width = size;
col.mx_internal::owner = owner;
}
This ought to do the trick (well, it did for us after a couple of days of swearing)
Is you horizontalScrollPolicy set to false on the datagrid?
"If the DataGrid's horizontalScrollPolicy property is false, all visible columns must fit in the displayable area, and the DataGrid will not always honor the width of the columns if the total width of the columns is too small or too large for the displayable area."
http://livedocs.adobe.com/flex/3/langref/mx/controls/dataGridClasses/DataGridColumn.html#width
I was able to get it to work by calling the above loop in a function twice... the first time it add the visible columns, the second time it sets the correct width. Not the best solution but I cannot spend any more time on it.
I've been playing around with different methods of determining at runtime the width of a "label" so that I can resize the "label" because I don't want it to truncate. I've finally found an easy solution through UITextField which allows me to set the .autoSize which is great! However, now I'm trying to "style" (simply adjust font and font size) of the UITextField but it seems that I have to do it manually with '.htmlText' (which I'll gladly accept if that is the ONLY way).
I'm using the .text to set the value of the label.
My test case involves a HBox (I'm actually using a Grid but they should be the same and I've done testing on both):
I style the HBox and the style carries through to the UITextField. I don't believe this will work for me because I have other components inside that I need to style differently.
I've tried: UITextFormat and TextFormat (I see that the .htmlText being updated accordingly but the output doesn't update. Then I noticed that whenever I called hbox.addChild(myUITextField) it would override the .htmlText
I've tried setting the style with myUITextField.setStyle("fontSize", 20) before and/or after the call to addChild neither of which made an impact on the display as per what I noted above.
Changes are being made but they seem to be overrided when I add it to the display.
So what do I need to do in order to style the UITextField aside from manually setting it along with my contents in .htmlText? Solutions not using UITextField is fine as long as there is some easy way of not truncating the text.
EDIT: I want to just do textField.setStyle('fontSize', 20) and expect that every time I change the text, I wouldn't need to use HTML to go with it (so I can just do textField.text = 'something else' and expect that it will still have a font size of 20). This is what I meant by not using .htmlText (sorry if I wasn't clear before).
2nd EDIT: I guess I should present the whole issue and maybe that'll clarify what I did wrong or couldn't achieve.
My intent is to have a Grid and add text into it. I do not want it to wrap or scroll so I add it to the next row in the Grid when the current row's children total width exceeds some number. In order to add it to the next row, I need to be able to calculate the width of the text. I would like to be able to style that text individually based on cases and there might be other components (like a TextInput). Essentially what I'm trying to accomplish is "Fill in the Blank".
I've included code to show what I'm currently doing and it works somewhat. It might be un-related to the original issue of styling but I can't figure out how to adjust the distance between each UITextField but aside from that this fits what I would like to accomplish. Relevant to the question is: I would like to change the way I style each UITextField (currently setting .htmlText) into something a bit straightforward though like I previously mentioned I'll gladly accept using .htmlText if that's the only solution.
So I have a Grid with x Rows in it and in each row, I have exactly one GridItem. Based on the input, I add UITextField and TextInput into the GridItem going on to the next GridItem when necessary. If you have a better way of doing so then that would be better but I guess what I really want is to find a different way of styling.
Also another problem, I'm not sure of the exact way to add a TextField into the display. I tried:
var t : TextField = new TextField();
t.text = "I'm a TextField";
hBox.addChild(t); // doesn't work
//this.addChild(t); // doesn't work either
But I get the following error:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.text::TextField#172c8f9 to mx.core.IUIComponent.
Here's what I have that's working.

After about 8 hours of searching for a solution to what would seem to be such a simple issue I FINALLY stumbled on your posts here... Thankyou!!!
I have been stumbling around trying to get TextField to work and had no Joy, Label was fine, but limited formatting, and I need to be able to use embedded fonts and rotate. After reading the above this finally worked for me:
var myFormat:TextFormat = new TextFormat();
myFormat.align = "center";
myFormat.font = "myFont";
myFormat.size = 14;
myFormat.color = 0xFFFFFF;
var newTxt:UITextField = new UITextField();
newTxt.text = "HELLO";
addChild(newTxt);
newTxt.validateNow();
newTxt.setTextFormat(myFormat);
The order of addChild before the final 2 steps was critical! (myFont is an embedded font I am using).
One again... a thousand thankyou's...

EDIT BASED ON THE ASKERS FEEDBACK:
I didn't realize you wanted to just apply one style to the whole textfield, I thought you wanted to style individual parts. This is even simpler for you, won't give you any trouble at all :)
var textFormat: TextFormat = new TextFormat("Arial", 12, 0xFF0000);
myText.setTextFormat(textFormat);
Be aware that this sets the style to the text that is in the TextField, not necessarily future text you put in. So have your text in the field before you call setTextFormat, and set it again every time you change it just to be sure it stays.
It's probably best if you use a normal TextField as opposed to the component. If you still want the component you may need to call textArea.validateNow() to get it to update with the new style (not 100% sure on that one though) Adobe components are notoriously bad, and should be avoided. :(
To see all available options on the TextFormat object see here
END EDIT ---------
This is easy enough to just do with CSS in a normal old TextField.
var myCSS: String = "Have some CSS here, probably from a loaded file";
var myHTML: String = "Have your HTML text here, and have it use the CSS styles";
// assuming your textfield's name is myText
var styleSheet: StyleSheet = new StyleSheet();
styleSheet.parseCSS(myCSS);
myText.autoSize = TextFieldAutoSize.LEFT;
myText.styleSheet = styleSheet;
myText.htmlText = myHTML;
Supported HTML tags can be found here

The reason you have a problem adding Textfield to containers is that it doesn't implement the IUIComponent interface. You need to use UITextField if you want to add it. However, that's presenting me with my own styling issues that brought me to this question.
A few things I know:
TextField is styled using the TextFormat definition, and applying it to the textfield. As Bryan said, order matters.
setStyle does nothing on IUITextField, and the TextFormat method doesn't seem to work the same as in normal TextFields. (Edit #2: Ahah. You need to override the "validateNow" function on UITextFields to use the setTextFormat function)
To autosize a TextArea, you need to do something like this (inheriting from TextArea):
import mx.core.mx_internal;
use namespace mx_internal;
...
super.mx_internal::getTextField().autoSize = TextFieldAutoSize.LEFT;
this.height = super.mx_internal::getTextField().height;
Found this code on, I think, on StackOverflow a while back. Apologies to the original author. But the idea is that you need to access the "mx_internal" raw textfield.
Text and TextArea have wrapping options. (Label does not). So if you set the explicit width of a Text object, you might be able to size using the measuredHeight option and avoid truncation.
(edit: That was #4, but stackoverflow parsed it into a 1...)
