Question

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 + ");");
