Show Tooltips for the images

The tooltips for the images, associated with the nodes can be displayed by using Syncfusion.Windows.Forms.ToolTipAdv along with handling treeViewAdv's MouseHoverEvent .The tooltips for the images are displayed in the same way as the tooltips for the nodes.Here PointToClient and PointToNode methods are used in the treeViewAdv.

C#

// Initialize
private Syncfusion.Windows.Forms.ToolTipAdv toolTipAdv1;
private void treeViewAdv1_MouseHover(object sender, System.EventArgs e)
{
   TreeNodeAdv node=new TreeNodeAdv();
   Point p=this.treeViewAdv1.PointToClient(Control.MousePosition);
   node=this.treeViewAdv1.PointToNode(p);
   Point mouseLoc=Control.MousePosition;
   mouseLoc.Offset(10,10);
   if(node==this.treeViewAdv1.Nodes[0])
   {
      this.toolTipAdv1.ShowPopup(mouseLoc);
   }
   if(node==this.treeViewAdv1.Nodes[1])
   {
      this.toolTipAdv2.ShowPopup(mouseLoc);
   }
   if(node==this.treeViewAdv1.Nodes[2])
   {
      this.toolTipAdv3.ShowPopup(mouseLoc);
   }
   if(node==this.treeViewAdv1.Nodes[3])
   {
      this.toolTipAdv4.ShowPopup(mouseLoc);
   }
}

VB

' Initialize
Private toolTipAdv1 As Syncfusion.Windows.Forms.ToolTipAdv
Private Sub treeViewAdv1_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs)
   Dim node As TreeNodeAdv = New TreeNodeAdv()
   Dim p As Point=Me.treeViewAdv1.PointToClient(Control.MousePosition)
   node=Me.treeViewAdv1.PointToNode(p)
   Dim mouseLoc As Point=Control.MousePosition
   mouseLoc.Offset(10,10)
   If node Is Me.treeViewAdv1.Nodes(0) Then
      Me.toolTipAdv1.ShowPopup(mouseLoc)
   End If
   If node Is Me.treeViewAdv1.Nodes(1) Then
      Me.toolTipAdv2.ShowPopup(mouseLoc)
   End If
   If node Is Me.treeViewAdv1.Nodes(2) Then
      Me.toolTipAdv3.ShowPopup(mouseLoc)
   End If
   If node Is Me.treeViewAdv1.Nodes(3) Then
      Me.toolTipAdv4.ShowPopup(mouseLoc)
   End If
End Sub
