AutoCompleteBox loses its highlighting when the itemsource collection changes. To reproduce this issue type in the AutoCompleteBox and while it’s active and the popup is open, trigger a collection change event. The highlighting will automatically disappear, now if the collection changes again the highlighting reappears. This keeps toggling back and forth.
Attached is the screenshot.
Below are the code snippets.

How can disable animation components - RadScheduleView?
This does not work:
Telerik.Windows.Controls.Animation.AnimationManager.IsGlobalAnimationEnabled = false;
Telerik.Windows.Controls.Animation.AnimationManager.SetIsAnimationEnabled(UIscheduler, false);
Thank you.

I am having some issues with finding what to call to set certain colors. If you look at the attached RadGridView you will see these problems:
1. The child template has that light grey background.
2. On the selected tab it is white.
3. The selected grid header column is an orageish color (also is an orangeish color when moused over).
What are the proper ways to fix these color issues? I've tried changing the style on almost everything and have had no success.

Hi Team,
I am setting current User Name in both of these places
1) At Constructor of my User Control (after calling "Initialize Component")
myRichTextEditor.CurrentUser = "My Current Logged in User";
2) "myRichTextEditor_CommentShowing" event.
private void myRichTextEditor_CommentShowing(object sender, CommentShowingEventArgs e)
{
e.AppearanceSettings.BorderBrush = new SolidColorBrush(Colors.Green);
e.Comment.Author = "My Current Logged in User";
}
However the "Author" Name is not displayed in "Comment".
Could you please help me to solve this.
Thanks.

I am setting the width of all the columns in the grid to Auto: column.Width = GridViewLength.Auto;
But the last column does not cover the entire area (attached image).
I also have changed the style of telerik:GridViewHeaderCell, and because the last column do not stretch i can see another cell with a different back ground color.
How can i change the color of that column header
Thanks

I'm trying to use the RadListBox control because of it's drag and drop features, but am running into a problem that only shows up when smooth scrolling is enabled. I've enabled smooth scrolling using the method posted elsewhere on the forums by setting the CanContentScroll property to False.
However, when this is enabled, and I click on an item in the list, the whole list scrolls up so that the clicked item is at the bottom of the viewable area. The resulting effect is that over several clicks, I've scrolled to the top of the list. This behavior doesn't happen when the ListBox scrolls by item (when CanContentScroll is not set to false).
I do not need the selection functionality of the ListBox, and I'm using it just for the built-in drag and drop features. If there's another way to do the drag and drop without a Listbox, that's fine.
I need the ListBox to not scroll when an item is clicked, or another solution to the problem. Without a resolution, I cannot use smooth scrolling, as this will be a deal-breaker for any user.
Here's a link to a project that will show the behavior: https://dl.dropboxusercontent.com/u/3583840/ProgrammingSolutions/TelerikDragAndDropTest2.zip
The project is for the Q1 2014 release, but I've tried the most recent one and I get the same results.

Can someone please comment on the satus of this bug.
I see a silverlight issue regarding this still open in PITS but do not know if this is already being tracked for WPF.
When using RadRibbonWindow maximized with Windows Taskbar set to Auto hide, when I move the mouse to the bottom of the screen, the task bar does not popup.
If I use a standards WPF window it does.
