This can be done by setting e.Active to false in BeforeNodePaint Event Handler.

C#

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



this.treeViewAdv1.OwnerDrawNodes = true;



//Handle the TreeViewAdv's BeforeNodePaint event as shown below :



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

{

e.Active = false;

}

VBNET

'Declare the new node object. 

Private NewNode As Syncfusion.Windows.Forms.Tools.TreeNodeAdv = New Syncfusion.Windows.Forms.Tools.TreeNodeAdv("Inserted Node") 

Private Sub button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) 

    Dim NewNode As TreeNodeAdv = New TreeNodeAdv() 



    ' Use Insert method to add nodes at particular index.

    Me.treeViewAdv1.Nodes.Insert(2, NewNode) 

End Sub
