Create an OnMouseOver event

[appletonrd]

Hi ppl,

 

I'm trying to create an event on a derived class, based on Microsoft.Web.UI.WebControls.TreeNode;

 

This object does not have any mouse movement related events, but I'd like to display a certain tooltip when the mouse hovers each element of this type.

 

I've done a few things, but I can't get it to catch the mouse over event. I am missing something, but what?

 

Webforms don't have mouse movement events either...

 

Thanks in advance

 

Here's the relevant portion of the code I have:

On the derived class:

 

namespace TestProj

{

public delegate void OnMouseOverEventHandler(object source, System.EventArgs e);

...

public class TNode : Microsoft.Web.UI.WebControls.TreeNode

{

public event OnMouseOverEventHandler OnMouseOver;

...

public TNode() : base()

{

this.OnMouseOver += new OnMouseOverEventHandler(this.MouseOverInterpret);

}

 

public void MouseOver(EventArgs e)

{

if ( OnMouseOver != null )

{ OnMouseOver(this, e); }

}

 

private void MouseOverInterpret(object sender, EventArgs e)

{ MouseOver(e); }

 

--------------------------------------

on the webform:

...

private void Page_Load(object sender, System.EventArgs e)

{

TNode lNode = new TNode();

lNode.Text = "A";

lNode.OnMouseOver += new OnMouseOverEventHandler(lNode_OnMouseOver);

}

 

private void lNode_OnMouseOver(object source, EventArgs e)

{

Response.Write(((TNode)source).Text);

}

whoa wait a second. . . events are processed on postback.

what you need to do is write javascript for the client side onhover event. . . thats the event in jscript right? onhover???
