How to display tooltips for the images associated with the nodes?

 

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
