Right clic on item B without unselect item A

[Julien LEBLANC]

Hello

I'm using Telerik Controls for Silverlight 3.

I implemented TreeView, and Context Menu.
Problem is :
- I select Item A
- I right-click on item B
- Context Menu for Item B is display
- But item B is also selected, instead of item A like I'd like to ...

Any idea to keep item A selected ?

Thanks
Julien

Hi Julien,

Thank you for contacting us. If you are using code similar to the Add/Remove/Disable example, you will have to modify the ContextMenuOpened event handler and comment the lines that select the TreeViewItem that is right-clicked:

private void ContextMenuOpened(object sender, RoutedEventArgs e)
{
    RadTreeViewItem treeViewItem = (sender as RadContextMenu).GetClickedElement<RadTreeViewItem>();

    if (treeViewItem == null)
    {
        (sender as RadContextMenu).IsOpen = false;
        return;
    }

    // if (!treeViewItem.IsSelected)
    // {
    //  RadTreeView1.SelectedItems.Clear();
    //  RadTreeView1.SelectedItems.Add(treeViewItem.Item);
    // }
}

I've attached a modified version of the Add/Remove/Disable example that shows one possible solution to your scenario. Have a look at it and let me know if it helps.

On a side note, I'd like to inform you that we've just released an online tool that allows you to reduce the size of your Silverlight applications. For more information, please visit http://blogs.telerik.com/blogs/posts/10-06-10/telerik_assembly_minifier.aspx

There seems to be a bug regarding the context menu and the TreeView that I am experiencing in my code and also can be replicated in the Add/Remove/Disable demo.

If you left-click on the Drafts node to select the node and then right-click on the Folder node, the Junk E-mails node is selected.  I would expect the Folder node to be selected.

What seems to be happening is when ever a node that is lower that the selected node is right-clicked, the node immediately preceding to the right-clicked node is selected regardless of the level.

Is there any work-around for this issue?

Thanks,
Glenn

Hello Glenn,

I couldn't reproduce the issue with the Add/Remove/Disable example in the QSF that you described. Can you please take a look at this video and let me know if I am missing something?

Thank you in advance.

Hi Tina:

My coworker does not have the issue either.  However, as you can see in this video, I am having the issue.

I am running Windows 7, IE 8.0.7600.16385, and Silverlight 4.0.50524.0

Thanks,
Glenn

Hello Glenn,

This issue is really strange. I tested the Add/Remove/Disable example on a machine with the same configuration as yours and everything worked as expected. This might be a shot in the dark but have you, by any chance, zoomed your browser while you were recording the video? If you manage to isolate the issue, contact us as soon as possible.

All the best,

It seems I did have my browser zoomed to 105%.  When the browser is zoomed, the TreeView gets confused.  Setting the compatibility mode to “EI 8 Compatibility View” seemed to resolved it when the browser is zoomed to 105%.

 

Curiously, I was only able to replicate the issue when the zoom was set to 105%.  All other zooms didn’t have any affect.

Thanks,
Glenn
