i have a silverlight application that uses Telerik controls. one dialog has couple text boxes of the following type:
telerik:RadTabControl Grid

                            <TextBox Grid.Column="1" Grid.Row="0" Width="200" Margin="2,2,20,2" Text="{Binding EditConcept.BusinessEntityName, Mode=TwoWay, ValidatesOnNotifyDataErrors=True, ValidatesOnExceptions=true, NotifyOnValidationError=True}" >

when i try to record in test studio the control is not found on playback. does the developer need to add more details for this control to be found?

I am new to this environment. using windows 7 and IE.

Hello Tushar,
     it's hard to say why the issue is occurring without some additional details. Here's a video detailing the info we usually need in order to troubleshoot an issue effectively:

I noticed your XAML code doesn't include an AutomationID for the TextBox control. While I doubt that this is the issue per se, it's still bad practice. It hurt UI Automation reliability considerably. Check out this article:
