Loading background width not 100%

[Mattia]

Hi,

I notice that on grid with ColumnSelctionButton the loading background is not expaded at 100%, as shown on the attachment, and the external area is active.

There is a way to expand the loading at 100%

 

Thank you

Hello Stefania,

Thank you for reporting this issue. I've logged a new bug report in our feedback portal which you can find here.

To show our gratitude for your help, I've awarded you with some Telerik points.

In the meantime, as a workaround, you can modify the control template of the RadGridView control and increase the ColumnSpan of the PART_GridViewLoadingIndicator element by 1.

For your convenience, I'm attaching the modified template for the Office_Black theme. If you're using a different one, you should modify it accordingly.
