How do I render a control in a group header?

[Thilo]

I have an  chart (sparkline) I am trying to render into a group header.

I have no problems accessing the group header and pushing text to it, but have no idea how to render a control and reading through all the documentation I haven't found out how to do it.

Simple rendering of text example:

       RadGrid1.MasterTableView.ColumnGroups.FindGroupByName("TrendChartHeader").HeaderText = "Hello World.";

Thanks for any assistance anyone can provide.

Hi,

The HeaderText is just a literal for the text, so you cannot add controls there.

You can use the GroupHeaderTemplate under MasterTableView to add controls decoratively: https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/functionality/grouping/group-header-and-footer-templates.

I'm attaching here a small sample that shows how you can put controls in the header, data bind them, and access their parent values (aggregates).
