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

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.

Split bar disappears when docking

In my wpf application I noticed that while using RadDocking users can drag windows into a layout so that the split bar between adjacent sections is no longer present. This is very annoying to the users.

This can easily be reproduced using the silverlight demo and probably the wpf one also.

In the "Split Containers" demo, drag pane "Pane Bottom 2" to the bottom half of "Pane Right 2". You will notice that before this "Pane Right 1" and "Pane Right 2" had a split bar between them. After they do not. This happens with other combinations also.

GridViewCheckBoxColumn not saving state after being checked

I am having trouble getting a bound boolean to a GridViewCheckBoxColumn to show its state.

<telerik:RadGridView Name="dgvBreaks" ShowGroupPanel="False" Margin="0,0,0,53" AutoGenerateColumns="False" SelectionUnit="Cell">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Price}" Header="Price" Width="120" IsReadOnly="True" />

<telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding MatchUs}" Header="Match Us" AutoSelectOnEdit="True" EditTriggers="CellClick" />

<telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding MatchThem}" Header="Match Them" AutoSelectOnEdit="True" EditTriggers="CellClick" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

It looks like everything is binding fine, but if I click on the checkbox and go to another cell, the state of the checkbox is reset. I bound a normal GridViewDataColumn to the boolean field and I can see that the value is updated each time I click on the cell.

I am using build version 2012.1.326.40
