Collapse Group show Group Footer

[Phillip]

How can I show the group footer when the group is collapsed?  So that the collapsed group would show the header with the name and expand/collapse button, and directly below it the footer with all the aggregates for the group.
Thanks

Hello Phillip,

Take a look at the following forum thread which discussed similar scenario.
Grid Collapse Group Footer at the Same Line.

Thanks,

I would like to try and show the aggregate in the header, but I'm having trouble following the setup.  By trouble, I mean that it appears that the calculations have to be done manually which seems to defeat the purpose of this control.  The video I watched seems to want the calculations to be done as far down as SQL which will make the grid extraordinarily more complex when factoring in paging and filtering.  Is this really how difficult it is or am I misunderstanding the documentation?  Thanks

Hello Phillip,

RadGrid gives you the opportunity to retain the visibility of the group footers when their corresponding group header row is collapsed. In order to switch on this feature, just set the GroupingSettings.RetainGroupFooterVisibility property to true. A live example is available here:
