I have an AutoCompleteBox defined like this:

<telerik:RadAutoCompleteBox Grid.Row="4" Grid.Column="1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="0,3,6,3"
     WatermarkContent="Interviewer's name..."
     DropDownItemTemplate="{StaticResource RoomInterviewerSearchAutoComplete}"
     BorderBrush="#FF25A0DA" BorderThickness="1"
     SelectionChanged="Acb_Interviewer_OnSelectionChanged" />
 <DataTemplate x:Key="RoomInterviewerSearchAutoComplete">
    <StackPanel Orientation="Horizontal">
        <TextBlock Text="{Binding}" Style="{StaticResource AutoCompleteStyle}" />


The ItemSource is set to a List<string>.

I then try something like this but acb_Interviewer.SelectedItem remains null and only the watermark is visible in the control.

string interviewerName = dbContext.Users.First(u => u.Id == interview.PrimaryUserId).FullName;
acb_Interviewer.SelectedItem = interviewerName;


 What am I doing wrong?

Hi Morgan,

We tried to reproduce the behavior you describe, but with no luck.
Please find attached a sample project we used for testing purposes. It would be of great help if you could modify it so that the described behavior to appear and send it back or send us a runnable sample project of your own. This way, we can be sure we're on the same page and could further investigate.

Looking forward to your reply.
