I have a dojox.EnhancedGrid.
- On load of the grid, I would like to scroll to and select the last row in the grid.
I would appreciate any help with this.
Thanks.
Try this, supposing you have a reference to your grid, called "grid", and that your grid uses pagination :
var lastRow = grid.store._arrayOfAllItems.length - 1;
grid.scrollToRow(lastRow);
var lastRowOnPage = grid.rowCount - 1;
grid.selection.addToSelection(lastRowOnPage);

I have a Blazor WASM application using a MudTable that displays many rows from List<T>.
The MudTable uses #ref="_mappingTable" to identify the table in code.
In code, I set the selected item:
_mappingTable.SetSelectedItem(specificItemFromTheList);
StateHasChanged();
This seems to work fine. However, I'd then like the table to automatically scroll so that item is now visible. It's not automatically doing that and not sure how to achieve that.
There is an open issue requesting a new function "Scroll to row in MudTable"
https://github.com/MudBlazor/MudBlazor/issues/5445
You can wait for that issue to be solved or try the alternative posted by the user geometrikal
Currently using this code to scroll a row into view. It assumes the
table rows are all the same height.
export function scrollMudTableToRow(rowIndex) {
var tableElement = document.querySelector("div.mud-table-container");
var tableHeight = tableElement.offsetHeight;
var tableOffset = tableElement.scrollTop;
var tableRowHeight = tableElement.querySelector("tr.mud-table-row").scrollHeight;
// Element is above view - scroll so it is at top
if (rowIndex * tableRowHeight < tableOffset) {
tableElement.scrollTo(0, rowIndex * tableRowHeight);
}
// Element is below view - scroll so that it is at bottom
else if ((rowIndex + 1) * tableRowHeight > tableOffset + tableHeight) {
tableElement.scrollTo(0, (rowIndex + 1) * tableRowHeight - tableHeight);
}
}
i would like to have one list select that will have more than one style, i put two kinds of object's one is a group of users (bold), rest are users (italic or regular) is it possible to add style that will be added to part of added obj?
My code looks like this:
for(Usr usr: userSearchResult){
listSelect.addItem(usr);
}
listSelect.addStyleName("bold");
for (Gr gr : groupSearchResult) {
searchList.addItem(gr);
}
and also have style set in css correct similar to this
.v-select-bold .v-select-select {
font-weight:bold;}
i would be glad to solve this by myself but that was two days ago now i'm in a dot ;)
Thanks in advance for help!
You can store your row as a label with style. In the container there will be a label instance. There you can simply add the style.
Container container = new IndexedContainer();
container.addContainerProperty(NAME_PROPERTY, Label.class , "");
for (int i = 0; i <= 50 ; i++) {
Item item = container.addItem(i);
Label label = new Label(HashUtils.getRandomSalt());
label.addStyleName(style)
item.getItemProperty(NAME_PROPERTY).setValue();
}
return container;
You can't style rows of a ListSelect. You can use a Table component with one column to achieve a similar result. Table.setCellStyleGenerator method is used for differentiating styles for each cell (each row in your case).
I am new to DoJo development so this could be basic.
I have created an EnhancedDatagrid and it shows the data fine.
The data comes from an JSON store in a different page.
I have a button which causes that one new entry is created in the datastore and then my datagrid is 'refreshed'. This works fine.
But now i want only as the last step to change the style of the first row in my datagrid.
(I need to make the newly added row more visible.)
But i simply can't figure out how to get a handle on the first row in a datagrid.
...
grid = new dojox.grid.EnhancedGrid({
id: strId,
store: store,
structure: layout,
}, document.createElement('div'));
dojo.byId(placeHolder).appendChild(grid.domNode);
grid.startup();
var row = grid.getItem(0); // ---get the first row. How ? And how to apply new style ?
...
Thank you in advance.
Solved the problem like this:
dojo.connect(grid, 'onStyleRow', this, function (row) {
var item = grid.getItem(row.index);
if (row.index == 0) {
row.customClasses = "highlightRow";
row.customStyles += 'background-color:#FFB93F;';
}
});
I use the 'Claro' theme and it prevented me to set the background color of the row-cells.
The solution was to set the customClasses to a style like this:
.highlightRow tr
{
background-color: #FF6A00 !important;
}
Found part of the solution here: http://dojo-toolkit.33424.n3.nabble.com/row-customStyles-was-overwrite-by-claro-theme-td3763079.html
I have a DataGrid in my project. It doesn't fit's the width of the form, so the scrollBar appears. The DataGrid, on it's initial state, displays a few columns and a part of the next column (which would appear after scrolling).
Is there any way, I can get the width of this, displaying part?
You should get the width of the parent object.
let's say the datagrid is in your application, then you should get the width of the stage.(stage.stageWidth)
If your datagrid is on a certain x location in your application (or any other parent object) then you should take the width of the parent object - the x value of your datagrid. (stage.stageWidth - dataGrid.x)
Ok, I had some time to dig more deeply in this problem. I've searched a few classes to see, how the Adobe was implementing those grid behavior (displaying columns partly). So, for those, who'll need to deal with this, the needed part is in DataGrid.as file, method configureScrollBars .. actually, this part of it:
// if the last column is visible and partially offscreen (but it isn't the only
// column) then adjust the column count so we can scroll to see it
if (collectionHasRows && rowCount > 0 && colCount > 1 &&
listItems[0][colCount - 1].x +
visibleColumns[colCount - 1].width > (displayWidth - listContent.x + viewMetrics.left))
colCount--;
else if (colCount > 1 && !collectionHasRows)
{
// the slower computation requires adding up the previous columns
var colX:int = 0;
for (var i:int = 0; i < visibleColumns.length; i++)
{
colX += visibleColumns[i].width;
}
if (colX > (displayWidth - listContent.x + viewMetrics.left))
colCount--;
}
That's pretty much all code, that needed to catch and measure all those tricky divided cols in a grid :)
var viewStack:ViewStack = new ViewStack();
viewStack.percentWidth = 100;
viewStack.percentHeight = 100;
viewStack.addChild(canVas1);
viewStack.addChild(canVas2);
viewStack.addChild(canVas3);
lb = new LinkBar();
lb.dataProvider=viewStack;
Its only displaying canVas3 contents not canVas1 and canVas2
thanks
I think that's what it's supposed to do. It just puts components one on top of the other like a deck of cards, with the topmost (last added) being visible. Check this out.
