I am using one of your example codes and seeing a different behavior when running the Project between .NET Framework 4 and 3.5 Framework in the Target framework property of the Project.
When I run in 4, I get a RED line between two Parent nodes. If I run in 3.5 I am not getting that red line.

This Red line appears when the Tree is in Tristate mode. It disappears when all the nodes are selected. Have you guys seen this problem?

Is this a bug? I am attaching screen shot of this.

I have used the example shown in this post.

RadGrid and GridViewComboBoxColumn Binding problems

Hi,

I am using WPF Telerik controls in a WPFApplication using MVVM pattern.

All controls binding is throw ObservableCollections, for the RadGrid the binding is fine but for the GridViewComboBoxColumn binding it's not.

In fact GridViewComboBoxColumn is binding to another ObservableCollections via
ItemsSource="{Binding MyCollection}"
DataMemberBinding="{Binding Property}"
DisplayMemberPath="Label"
SelectedValueMemberPath="Value"

but it doesn't work.

Can GridViewComboBoxColumn support another collection binding other than RadGrid Collection Binding ??

Thx

Set expanded state on load...

I'm trying to set the expanded state on load. I'm using the following RowLoaded handler.

private void PspTreeListView_RowLoaded(object sender, Telerik.Windows.Controls.GridView.RowLoadedEventArgs e)

{

PspTreeViewObject pspTreeViewObject = e.DataElement as PspTreeViewObject;

TreeListViewRow treeListViewRow = e.Row as TreeListViewRow;

if (treeListViewRow != null && pspTreeViewObject != null)

{

treeListViewRow.IsExpanded = pspTreeViewObject.IsExpanded;

}

}>

This works to set the expanded state properly, but then none of the items in the treeview can be expanded or contracted. I tried setting IsExpandable to true for the items, but that didn't work either. It seems that once the initial state is set, it cannot be changed.

Any ideas on how I can fix this?

column header keyboard accessible?

Is the GridView column header keyboard accessible? Can I tab to it and activate sorting with the keyboard? The native WPF listview doesn't support this and we are looking for a control that does.

Thanks,
Derek

Is there or will there be in the near future the ability to modify the Zoom range? I would like to be able to set the zoom property to something lower than 0.5.

Binding to Self-Reference Hierarchy and Drag/Drop

Hi guys,

I've followed the self-reference hierarchy example and have implemented the custom DataItemCollection. The tree binds great and I am able to view all the tree items. However, now I want to have the drag/drop ability too, I've found that I can't "Drop-Inside" and also, when I can, drop before or after the program gives me the following exception:

NullReferenceException
at Telerik.Windows.Controls.RadTreeView.EndDrop(FrameworkElement dropTarget, IEnumerable draggedItemsEnumerable) in c:\\Builds\\WPF_Scrum\\Release_WPF\\Sources\\Development\\Controls\\Navigation\\TreeView\\RadTreeView.cs:line 2147\r\n at Telerik.Windows.Controls.RadTreeView.OnDropComplete(FrameworkElement dropDestination, IEnumerable draggedItems) in etc...

I have pretty much following the example found in the documentation exactly and extended the ObservableCollection. I have only enabled the property IsDragDropEnabled to true to turn on this feature. Is there something else I must do to make the dropping work?

Thank you,

Tim.

Only bing road map available

I am using the Bing map provider and only the road view is available. Aerial is enabled but when clicked the map flashes and then goes back to road. Birdseye view is disabled. Are the modes controlled by the map key? I think they used to work, but I updated the telerik version and map key.
