How to achieve expand and collapse behaviors with WinForms GroupBar?
Expand and collapse
You can achieve expand and collapse behaviors of WinForms GroupBar like in Outlook2013 by handling the StateChanged event in GroupBar and the SplitterDistance property in SplitContainerAdv. You can refer to the following code example.
C#
private void groupBar1_StateChanged(object sender, EventArgs e)
{
if (groupBar1.Size.Width > this.groupBar1.CollapsedWidth)
{
this.splitContainer1.SplitterDistance = this.groupBar1.Width;
}
else
{
this.splitContainer1.SplitterDistance = groupBar1.Width;
}
}
VB
Private Sub groupBar1_StateChanged(ByVal sender As Object, ByVal e As EventArgs) Handles groupBar1.StateChanged If groupBar1.Size.Width > Me.groupBar1.CollapsedWidth Then Me.splitContainer1.SplitterDistance = Me.groupBar1.Width Else Me.splitContainer1.SplitterDistance = groupBar1.Width End If End Sub
You can refer to the following link for samples that illustrates the above code example.
