How do I hide the dotted selection rectangle around the selected node ?


Setting the TreeViewAdv's KeepDottedSelection property to false hides the dotted rectangle around the selected node when the TreeViewAdv loses focus.


this.treeViewAdv1.KeepDottedSelection = true;


Me.treeViewAdv1.KeepDottedSelection = True

If you do not wish to have the dotted rectangle when the node is selected and TreeViewAdv has focus, then use the following workaround :

1. Set the TreeViewAdv's OwnerDrawNodes property to true.


this.treeViewAdv1.OwnerDrawNodes = true;


Me.treeViewAdv1.OwnerDrawNodes = True

2. Handle the TreeViewAdv's BeforeNodePaint event as shown below :


private void treeViewAdv1_BeforeNodePaint(object sender, Syncfusion.Windows.Forms.Tools.TreeNodeAdvPaintEventArgs e)


e.Active = false;



Private Sub treeViewAdv1_BeforeNodePaint(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Tools.TreeNodeAdvPaintEventArgs)

e.Active = False

End Sub
