     I have a RadGrid that uses:
                <EditFormSettings CaptionFormatString="Update Project" InsertCaption="New Project" PopUpSettings-ShowCaptionInEditForm="true" UserControlName="Project.ascx" EditFormType="WebUserControl"><br>                    <EditColumn UniqueName="EditCommandColumn1"><br>                    </EditColumn><br>                    <PopUpSettings KeepInScreenBounds="False" Width="1000px" Height="800px" OverflowPosition="UpperRight" Modal="true" /><br>                </EditFormSettings>

 

On the user control, I have a RadComboBox that uses a regular asp.RequiredFieldValidator with runat="server".

 

When the combobox is not populated, the validation works and the asterisk displays, but ONLY after the whole popup window blinks.  Is there any way I can stop this blink?  Why is it happening?  I can post more code if necessary.

Hello Jason,

 

You can try to check the web.config file of the project to see whether the ValidationSettings:UnobtrusiveValidationMode property is enabled as demonstrated here:
