Hi,

I've been struggling with this as well, and have come up with something of a solution for me ... hopefully it might help ...

My taskpanel is on a user control and looks like this ...

It has just 2 groups. The first, for "Settings", is a fixed size.  The second group is the "Results".  I needed the second group to change size depending on whether the first group is expanded or not.  Each taskpanel group has just a single picture box control assigned to it.  Once the picture box is resized, its own resize event takes care of all of the individual controls.

Here's the code I used -

Private Enum TaskPanelGroups

tpgSettings = 1

tpgResults

End Enum

Private Sub TaskPanel1_GroupExpanded(ByVal Group As XtremeTaskPanel.ITaskPanelGroup)

With TaskPanel1

If .Groups(tpgSettings).Expanded Then

'settings group IS expanded

 .Groups(tpgResults).Items(1).SetSize picResults.width, (UserControl.ScaleHeight / 15) - 140, False

Else

'settings group NOT expanded

.Groups(tpgResults).Items(1).SetSize picResults.width, (UserControl.ScaleHeight / 15) - 45, False

End If

End With

End Sub

Hopefully this might help,

Rohan
