Hi,
I've got a rad expander within my application using a custom header containing several controls one of which is a text box.

All of the other controls work correctly apart from the text box, when attempting to put a space within the textbox it expands the expander.

Is there any way to disable this functionality, i've seen one solution but that involved changing the control header using a style which I don't want to do.

Thanks in advance.

Hello Matt,

Unfortunately , this is a bug in the RadExpander. We logged it in our PITS and we also updated your telerik account points. As a workaround, you can use the KeyDown event of the TextBox, implement the logic of the Space Key in TextBox and then set e.Handled = true to prevent the expansion.
 

Kind regards,

Hi, it still does not work with version 2012 Q3.

As a workaround, I took out the textbox from the header and placed it outside of the RadExpander.
It  looks like it is inside the header.

<Grid x:Name="LayoutRoot">
     <telerik:RadExpander VerticalAlignment="Top">
         <TextBlock Text="Content of the Expander" />
     </telerik:RadExpander>
     <TextBox
         Width="250"
         Margin="25,0,0,0"
         HorizontalAlignment="Left"
         VerticalAlignment="Top" />
 </Grid>


If the expand direction of your RadExpander is other than down, you will have to do some additional layout to achieve the same thing.

Regards,

Iosu.

Hello Andreas,

 Could you please elaborate more on your exact scenario? RadAutoCompleteBox has built-in TextBox and this is different from the Expander's custom scenario. We highly encourage you to open a new support thread and describe your issue. It would be also great if you can isolate your issue in a runnable sample that we can investigate. Thank you in advance for your cooperation.

All the best,
