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

Platform: WinForms |
Control: TreeViewAdv |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014

 

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

C#

this.treeViewAdv1.KeepDottedSelection = true;

VB

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.

C#

this.treeViewAdv1.OwnerDrawNodes = true;

VB

Me.treeViewAdv1.OwnerDrawNodes = True

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

C#

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

{

e.Active = false;

}

VB

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

e.Active = False

End Sub
