When I scroll a TreeViewAdv control with a gradient background, it is not rendered correctly. Why?
When the BackgroundColor Style property is set to Gradient, you need to call Refresh() during both horizontal and vertical scrolling to ensure that it is rendered properly.
[C#] //Call Refresh during Horizontal and Verical Scrolling private void treeViewAdv1_VerticalScroll(object sender, System.Windows.Forms.ScrollEventArgs e) { this.treeViewAdv1.Refresh(); }
private void treeViewAdv1_HorizontalScroll(object sender, System.Windows.Forms.ScrollEventArgs e) { this.treeViewAdv1.Refresh(); }
[VB.NET] 'Call Refresh during Horizontal and Verical Scrolling Private Sub treeViewAdv1_VerticalScroll(ByVal sender As Object, ByVal e As System.Windows.Forms.ScrollEventArgs) Me.treeViewAdv1.Refresh() End Sub Private Sub treeViewAdv1_HorizontalScroll(ByVal sender As Object, ByVal e As System.Windows.Forms.ScrollEventArgs) Me.treeViewAdv1.Refresh() End Sub
