I am trying to add a edit method to my grid from my data source in the form. I have the following code for the edit method:
edit boolean markLine(
boolean set,
Datasource _datasource,
boolean _mark
)
{
if (set)
{
if (!_mark)
{
if (selectedLines.exists(_datasource.RecId))
{
selectedLines.remove(_datasource.RecId);
}
}
else
{
selectedLines.insert(_datasource.RecId,_datasource.recVersion);
}
}
return selectedLines.exists(_datasource.RecId);
}
I then drag that into a grid which has the datasource specified in it and contains other fields from that datasource. Yet, when I try to use it in the grid, it is not possible to check the box.
I am using a view for my data source, not a table. I am not sure if this is the reason for it or if there is something else that is the problem. Any idea what the problem could be here?
Thanks in advance.
Edit
AllowEdit on the data source is true.
Ok, I checked around some more and found the following in the AX documentation about views
Views are read-only. The data fields and tables that a view uses cannot be updated from that view.
Therefore, edit methods will not work because views cannot be edited in the first place.
Edit
A workaround for this is to override the mouseDblClick method in the grid. Add the following code lines after the super():
Datasource_ds.selectedLines(true, Datasource, !selectedLines.exists(Datasource.RecId));
Datasource_ds.refresh();
Then when the user double clicks a method, it is selected.

I am implementing a category mapper. There are 2 TreeViews. Both contain categories from different sources. (Even they look like from the same source)
The user should be able to map ONE category from the left to multiple of the right treeview. This gets stored in a config file.
However, when the view is initially loaded and the user clicks on a category on the left, I want to preselect the mapped categories on the right, loaded from the config file.
I saw that I can do this with ONE selection, but I don't see an option to do this for multiple ones.
How can I achive this?
Here a ootb running demo implementation
I went through your gist and it seemed that the problem was binding selections right? I did some light digging and found that binding observable lists isn't easy. I don't think I even saw a solution that wasn't just adding listeners to mock a binding. However, wrapping that list in a SimpleListProperty seemed to do the trick. Here's a demo:
class TestView : View() {
// This mocks your target list in the ViewModel
val targetList = SimpleListProperty(listOf<String>().asObservable())
override val root = vbox(10) {
// Both table views and tree views use an Observable Selection list
listview(listOf("asefas", "asefasef", "asefasefasefase").asObservable()) {
// Wrap in SimpleListProperty, then bind
targetList.bind(SimpleListProperty(selectionModel.selectedItems))
selectionModel.selectionMode = SelectionMode.MULTIPLE
}
setPrefSize(300.0, 300.0)
}
init {
// Target list now reflects changes made to selection model
targetList.addListener { _, _, change ->
println("Selections changed to: $change")
}
}
}
When I add a member to my BOModel and write a simple expression like:
[Name] +' ' + [Age]
But in runtime I see something like this:
ROP.Module.BusinessObjects.ROP.Product(4)
That field just show me "OId" but not show related value!
Note: that fields are simple textbox is OK, but that fields came from relation to other table are missing.
Please guide me how to solve this issue.
Some screen shot :
[![http://i.stack.imgur.com/JAQXn.png][1]][1]
[![http://i.stack.imgur.com/j5I2Q.png][2]][2]
in your class, add this line :
namespace YourApp.Module.BusinessObjects
{
[Default Property ("Field401")] // add this line
[DefaultClassOptions]
Field401 is the field you want to display during the runtime.
You should use the XafDefaultProperty attribute.
namespace Rop.Module.BusinessObjects
{
[XafDefaultProperty("DescRegistation")]
[DefaultClassOptions]
public partial class Product
{
...
}
}
If the property that you want to display in another object's view is not the one you wish to set as default, then you can set it in the Model Editor as shown in the above link.
I want to create a custom filter for my DataTable. I would like to create a button that, when clicked on it, changes the table its data. I know about the ChoiceFilteredPropertyColumn that wicket has to offer but this is, according to my understanding of it, a dropdown filter.
I am trying to achieve something like the following picture (Pancakes is the clickable button):
Could someone point me in the right direction?
Well... the superclass of ChoiceFilteredPropertyColumn is FilteredPropertyColumn which might do the trick. Otherwise you could always implement your own Column that implements IFilteredColumn the way you like it.
Look at how the implemented `DataTable' here: http://www.packtpub.com/sites/default/files/1605OS-Chapter-5-Displaying-Data-Using-DataTable.pdf
Then you could implement your dropdown button filter like you want it and filter with the selected value the DataTable.
I solved this question by creating a custom filter (just a panel with some markup) and return it in the getFilter method of a custom FilteredPropertyColumn.
FilteredPropertyColumn:
http://wicket.apache.org/apidocs/1.4/org/apache/wicket/extensions/markup/html/repeater/data/table/filter/FilteredPropertyColumn.html
getFilter method:
http://wicket.apache.org/apidocs/1.4/org/apache/wicket/extensions/markup/html/repeater/data/table/filter/IFilteredColumn.html#getFilter%28java.lang.String,%20org.apache.wicket.extensions.markup.html.repeater.data.table.filter.FilterForm%29
ButtonFilter class:
public class ButtonFilter extends Panel {
...
}
In custom FilteredPropertyColumn class:
#Override
public Component getFilter(String componentId, FilterForm<?> form) {
return new ButtonFilter<Y>(componentId, getFilterModel(form), filterChoices);
}
I've been using hardcoded hyperlinks for my web app navigation, but the app has grown since and managing it is becoming a real pain. I've decided to replace what I have with the TreeView control, however I want to make several changes to the way it looks.
Is there any property that needs to be set, that would allow user to expand the TreeView node by clicking its text instead of +/- ?
I've already set ShowExpandColapse to 'false'.
I want my final result to end up as something similar to the TreeView on the left of the MSDN site.
Could anyone point me at the right direction please?
Set TreeNode.SelectAction to either Expand, or SelectExpand.
you can use xml data source or direct binding from db to treview
in the TreeView DataBound event we can write d recursive function as below to fetch each node and assign expand action to them.
protected void TreeView1_DataBound(object sender, EventArgs e)
{
foreach (TreeNode node in TreeView1.Nodes)
{
node.SelectAction = TreeNodeSelectAction.Expand;
PrintNodesRecursive(node);
}
}
public void PrintNodesRecursive(TreeNode oParentNode)
{
// Start recursion on all subnodes.
foreach(TreeNode oSubNode in oParentNode.ChildNodes)
{
oSubNode.SelectAction = TreeNodeSelectAction.Expand;
PrintNodesRecursive(oSubNode);
}
}
I think you just have to do this in code: handle the Click event, determine the currently-selected tree node, and toggle its Expanded property (I think that's what it's called here).
You can do this only this way! http://geekswithblogs.net/rajiv/archive/2006/03/16/72575.aspx

This seems like something that should be painfully simple, but I can't even find how to loop through rows in a Flex DataGrid.
Basically what I'm trying to accomplish is something like this pseudo-code:
for each(var row:Row in myDataGrid.Rows)
{
if(row.DataObject.Number == 1)
{
row.Color = Red;
}
}
I'm trying to have a Save button that upon being clicked either processes the save, or highlights the invalid rows and pops up a message telling the user why the rows are invalid. Because of some other complexities, I am not able to validate each row as it is entered. Any help is appreciated! Thanks.
Data grids are intended to be driven by their data rather than manipulated directly. One way to accomplish what you are trying to do is to add some sort of property, say "valid", to the data objects in your provider and add code to the renderer to alter its appearance based on the state of "valid". In that way you could loop through the objects in your data provider and set the "valid" property based on your validation check, which would cause the rows in the data grid to change their appearance automatically.
Hope that helps.
Try something like this:
for each(var o:Object in myDataGrid.dataProvider)
{
if(o.Number == 1) {
myDataGrid.selectedItems.push(o);
}
}
In your mxml you can set the selectionColor of the datagrid to red. See: http://blog.flexexamples.com/2008/02/19/setting-the-selection-color-and-selection-disabled-color-for-a-row-in-the-flex-datagrid-control/
Let me know if this works for you!
I am not sure you can do it on the data grid itself, but if you have an item renderer for each of the items, you can have your highlighting logic there.
basically, you define your datagrid's item renderer class:
<mx:DataGrid itemRenderer="ItemRendererClass"(...) ></mx:DataGrid>
and then you define the class "ItemRendererClass" as implementing IDataRenderer:
implements="mx.core.IDataRenderer"
This is a simplistic explanation, assuming you can figure out how to do this on yourself :)
I achieved this by overriding the set data. I have provided the sample code below.
override public function set data(value:Object):void
{
super.data=value;
if(value!=null && value.hasOwnProperty("state") && value.state == "Final State"){
setStyle("color", 0xb7babc);
}else{
setStyle("color", 0x000000);
}
this.selectable=false;
super.invalidateDisplayList();
}
