Public Property SplitterMoving As Boolean

public bool SplitterMoving {get; set;}

Example

The following code fragment demonstrates the usage of the SplitterMoving flag to avoid the SplitControl repaint issue during splitter moving.

bool first = true;
private void splitContainer1_SplitterMoving(object sender, SplitterCancelEventArgs e)
{
	if (first == true) {
		MainViewport.SplitterMoving = true;
		first = false;
	}
}
private void splitContainer1_SplitterMoved(object sender, SplitterEventArgs e)
{
	first = true;
	MainViewport.SplitterMoving = false;
}

VB.NET

Dim first As Boolean = True
Private Sub SplitContainer1_SplitterMoving(ByVal sender As System.Object, ByVal e As System.Windows.Forms.SplitterCancelEventArgs) Handles SplitContainer1.SplitterMoving
    If first = True Then
        MainViewport.SplitterMoving = True
        first = False
    End If
End Sub
Private Sub SplitContainer1_SplitterMoved(ByVal sender As System.Object, ByVal e As System.Windows.Forms.SplitterEventArgs) Handles SplitContainer1.SplitterMoved
    first = True
    MainViewport.SplitterMoving = False
End Sub
