Register OnMouseOver-Event from CodeBehind?

Question

Hi guys,

I wan't to register the OnMouseOver and OnMouseOut-Event for an Image from the Code behind, because I must different if the user is logged in or not. Any ideas?

Answer 1

You can add an attribute to the object.

e.g.

 Image img = new Image();
 img.Attributes.Add("onmouseover", "myjavascriptfunction();");

To set the paramater based on the id of the object, using this:

 Image img = new Image();
 img.Attributes.Add("onmouseover", "myjavascriptfunction(" + img.ClientID + ");");

Answer 2

On solution would be to use a css class and jQuery:

  <img id="generatedId" class="myHoverImage" />

javascript:

$("img.myHoverImage").mouseover ( function() {

  // you can access the generated id:      

  alert ( this.id );

  // --> your code goes here <-- \\      

});

Using ck's example, you can achieve what you're trying to do using the ClientID property on your server control. Like this:

yourImage.Attributes.Add("onmouseover", "jsfunction(" + yourImage.ClientID + ");");
