Problem editing RadTreeViewItem, PreviewEditStarted not fired

[Fernando]

Hello i have a problem, trying to edit a oRadTreeViewItem

All tree is generated by code (not binding)

RadTreeViewItem oRadTreeViewItem = new RadTreeViewItem();
oRadTreeViewItem.Header = "Name";
oRadTreeViewItem.IsEditable = true;
oRadTreeViewItem.PreviewEditStarted += radTreeView_PreviewEditStarted;
oRadTreeViewItem.Edited += DataViewExplorerTree_Edited;
oRadTreeViewItem.EditStarted += radTreeView_EditStarted;
DataViewExplorerTree.Items.Add(oRadTreeViewItem);

I use a context menu to edit the name of tree node using GetItemByPath to find the node

 

 

 


RadTreeViewItem oRadTreeViewItem = DataViewExplorerTree.GetItemByPath("Path of the item");



The item put's in edit mode but loss the header content. it's turn in Edit mode with empty content.

I try to catch radTreeView_EditStarted and radTreeView_PreviewEditStarted in order to rewrite the original header text. But only DataViewExplorerTree_Edited is fired when edit ends. Also trying to set focus to the edit box, but without success (tree is inside a dockpane)

private void DataViewExplorerTree_Edited(object sender, Telerik.Windows.Controls.RadTreeViewItemEditedEventArgs e)
        {
            RadTreeViewItem targetItem = e.Source as RadTreeViewItem;

           // (e.Source as RadTreeViewItem).IsInEditMode = false;
           //(e.Source as RadTreeViewItem).Background = new SolidColorBrush(Colors.Red);
        }

        private void radTreeView_PreviewEditStarted(object sender, Telerik.Windows.Controls.RadTreeViewItemEditedEventArgs e)
        {
            RadTreeViewItem targetItem = e.Source as RadTreeViewItem;
        }

        private void radTreeView_EditStarted(object sender, Telerik.Windows.Controls.RadTreeViewItemEditedEventArgs e)
        {
            RadTreeViewItem targetItem = e.Source as RadTreeViewItem;
        }

I try to use

oRadTreeViewItem.IsInEditMode = true;

or

 oRadTreeViewItem.BeginEdit();  (ALWAYS return false)

to start to edit node only first runs, the second always return me false.

Any ideas?

Thanks in advance.

Hi Fernando,

There is known issue with setting the IsInEditMode property of the RadTreeViewItem - in certain scenarios, the Header text is lost like in your case. However, you should be able to start editing an item using the BeginEdit() method.

 I prepared a sample project using the code snippets you provided. Can you please have a look at it and let me know if it works for you or if I am missing something? Thank you in advance.

Thanks Tina, i use your sample and runs ok.  I added a Docking pane scenario to this sample (in order to simulate my project)  and runs ok.

But in my project, when i use BeginEdit() for this RadTreeViewItem i get this exception:
