When I scroll a TreeViewAdv control with a gradient background, it is not rendered correctly. Why?

Platform: WinForms |
Control: TreeViewAdv |

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
