Model.SplitterMoving Property
WinForms: When the viewport control is hosted inside a SplitContainer control an annoying repaint issue is present during SplitContainer splitter moving.
WPF: When the viewport control is hosted inside a Grid control with GridSplitter an annoying repaint issue is present during GridSplitter moving.
Setting properly this flag it can be avoided.
The following code fragment demonstrates the usage of the SplitterMoving flag to
avoid the SplitControl repaint issue during GridSplitter moving.
// WinForms
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;
}
// WPF
private void GridSplitter1_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
MainViewport.SplitterMoving = true;
}
private void GridSplitter1_PreviewMouseUp(object sender, MouseButtonEventArgs e)
{
MainViewport.SplitterMoving = false;
}
