I have an ASP.NET control that has an onclick event handler rendered inline on the element. I would like to call that function and have it raise the target control's server side event handler.
<asp:CheckBox ID="Foo"
runat="server"
AutoPostBack="true"
Text="Foo" />
<a href="#"
onclick="javascript:setTimeout('__doPostBack(\'Foo\',\'\')', 0)">Test
</a>
I created the checkbox, looked at the rendered function on the field, and then copied that into the onclick on the anchor element.
The anchor will raise a postback, but the event handler for the check box is not raised.
protected override void OnLoad(EventArgs e)
{
// fires for checkbox
// fires for anchor (the anchor does cause a postback)
}
void Foo_CheckedChanged(object sender, EventArgs e)
{
// fires for checkbox
// does not fire for anchor
}
protected override void OnInit(EventArgs e)
{
this.Foo.CheckedChanged += new EventHandler(Foo_CheckedChanged);
}
Is it possible to do this?
