Hello,
Here is my gridview.

{

public MainPage()

{

InitializeComponent();

DataContext = from i in Enumerable.Range(0, 10)

select new MyObject()

{

ID = i,

Name = String.Format("Name{0}", i)

};

}

public class MyObject

{

public int ID { get; set; }

public string Name { get; set; }

public IEnumerable<MyObject2> Items

{

get

{

return from i in Enumerable.Range(0, 10)

select new MyObject2()

{

x = i

};

}

public class MyObject2

{

public int x { set; get; }

public IEnumerable<MyObject2> Items

{

get

{

return from i in Enumerable.Range(0, 10)

select new MyObject2()

{

x = i

};

}

private void SubGrid_DataLoading(object sender, GridViewDataLoadingEventArgs e)

{

var grid = (GridViewDataControl)sender;

var d = new GridViewTableDefinition();

d.Relation = new PropertyRelation("Items");

grid.TableDefinition.ChildTableDefinitions.Add(d);

grid.AutoGenerateColumns = false;

grid.Columns.Add(new GridViewDataColumn() { DataMemberBinding = new Binding("x") });

}

For the firs time it is child one and then it becomes self-hierarchical. Everything is OK, but in the real programm we use WCF service and MyObject and MyObject2 are DataContracts, and we need to call a WCF service in the get-methods of the Items property.
So, I ask you for help: How could I call the WFC method or maybe there is another way to make such hierarchy.

How do I hide a row?

I try to hide a row that have a specific status, When I do like the code below. the row is not shown, but there is space left "blank" in the grid where the row should be. I also tested with Height=0

private void radGrid_RowLoaded(object sender, RowLoadedEventArgs e)

{

GridViewRow row = e.Row as GridViewRow;

if (row != null)

{

MyClass _MyClass = row.DataContext as MyClass;

if (row != null && _MyClass != null)

{

row.IsExpandable = _MyClass.Category.Equals(5);

}

else

{

row.IsExpandable = false;

}

if (_MyClass.MediaCategory.Equals(5) && _MyClass.Status.Equals(-1))

{

row.Visibility = System.Windows.Visibility.Collapsed;

}

Any suggestions?

Controls / Textboxes within RadTreeItem

Ok, i have a RadTreeView with an Item Source of List<ActivityControl> which is a user control that has a text box, a canvas and a text box in it... my problem is that because the text box is within the RadTreeView whenever i try and click and drag to select text it tries to drag and drop the Selected item!?! this is going to be a pain for users to try and edit text if they cant drag to highlight....

i've uploaded a video to give you an idea!

http://www.screencast.com/users/kevinrhynas/folders/Jing/media/8fb40a9e-c5ce-4c6f-83ba-20054a6d466f

Also on a side note... i pressume that it is the header of each RadTreeItem that sets the "preview" in the draggable bit... how can i set this if i've simply set the "itemsource" to be a list.. as opposed to manually adding these items??

RadTreeListView - different type children

I don't see a RadTreeListView forum yet, so I'm sticking this here.

I have a list of objects of type SkuForecast. Each SkuForecast has a list of objects of type SkuForecastArchive which has the same columns as the SkuForecast.
I'm trying to setup the RadTreeListView control to work with them, but I'm getting an InvalidCastException error cannot cast type SkuForecastArchive to type SkuForecast

What am I doing wrong?
