RadGridView.ChildTableDefinitions Column Header Text

[Ilya]

I have a GridView with ChildTableDefinitions which adds a column with pluses to expand and see child gridviews. How do I put a header title on that column?

Hello Ilya,

The question in this thread is similar to one logged in one of your latest ticket threads. I will copy the answer from my colleague Dilyan here so that the community can take advantage of it:

I prepared a small sample project which I believe satisfies your requirements. For this purpose, I've handled the Loaded event of the parent RadGridView control.

In the Loaded handler, I create a glyph icon, which upon hover shows a tooltip that indicates that the +/- buttons need to be clicked for the rows to be expanded. I suggest this approach because if you decide to display text which has a width wider than that of the default one for the cells which display the buttons, further modifications will be required, which are not straightforward.
