Hello,

I'm having trouble to automatically expand all groups within a RadGridView. I set the AutoExpandGroups to true and also call the RadGridView's method ExpandAllGroups(). It does expand all the groups, but it also adds an unwanted white space to my grid, that vanishes after I manually collapse one of the groups.

I also tried to set the GroupRenderMode to Flat. It solves the white space issue, but it adds unwanted information to my groups' headers.

Is there a way to make it work properly?

 

*Telerik UI for WPF version 2015.3.930.45

Thanks in advance.

Hi Gabriel,

In general, with both GroupRenderMode's, the GroupHeader should be displaying the value of the property over which the control is grouped. Can you please clarify what is the undesired content being added with Flat GroupRenderMode?

Hi Stefan, thanks for the reply. Yes, the Flat GroupRenderMode is showing the value of the property, but I don't need it to be displayed. Is there a way to hide it?

Hello Gabriel,

As stated in my previous reply, the property value should be displayed with both GroupRenderMode's. Since you need to remove it, you can modify the template of GridViewGroupRow and simply remove its ContentPresenter element.

In addition, you may find the Editing Control Templates topic useful on this matter.
