Hierarchy expanding collapsing event?

[Mark]

Is there an event that is thrown when a gridview is expanded or collapsed via the + or minus - being clicked in the parent row?

I have tried using the event, GroupExpanded but it is not being thrown.

The underlying reason for this is that my entire program has a black background, but when I use the RadGridView and set its DockStyle to Fill, the area not populated by the rows is defaulted to white.  I have not been able to change the color of this portion of the control, so I am using a Black panel behind the RadGridView, and dynamically changing the height of the GridView when rows are added via the RowsChanged event.

Hello,

You can change the back colour of that area using the following code

this.radGridView1.TableElement.BackColor = System.Drawing.Color.Black;
this.radGridView1.TableElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;

(see screenshot)
If this is not what you meant, please let me know and I'll do my best to address your issue
