You can handle the click event on a DIV as the code following (div1 is the id of the DIV element)
public partial class _Default : System.Web.UI.Page, IPostBackEventHandler
{
protected void Page_Load(object sender, EventArgs e)
{
div1.Attributes["onclick"] = ClientScript.GetPostBackEventReference(this, "ClickDiv");
}
protected void Div1_Click()
{
}
#region IPostBackEventHandler Members
public void RaisePostBackEvent(string eventArgument)
{
if (!string.IsNullOrEmpty(eventArgument))
{
if (eventArgument == "ClickDiv")
{
Div1_Click();
}
}
}
#endregion
}
Hope this might help you, if it is server side event handler for Div click.
