Question

I have something that depending if it is clicked or unclicked will do something. The thing is, that i tried to do an onclick and it will not fire. Is there some other thing that is needed for selecting/unselecting a checkbox?

ASP:

<div id = "gridDiv">
    Turn on/off some code: 
    <asp:Checkbox runat="server" name = "gridlock" id = "gridLockAttribute" />
</div>

ClientSide:

$("#gridLockAttribute").click(function(){
   try{
      alert("test");
   }catch(err){

   }
});

It doesnt seem to alert.

ASP.NET may be name-mangling your ID if the control is within another control, so things like $("#gridLockAttribute") won’t work. You have to use either:

$("#<%= gridLockAttribute.ClientID %>")

Or:

$('[id$=gridLockAttribute]')

I’d prefer the first method.

Furthermore, if you are trying to get the checkbox to cause a postback automatically, you’ll need to set the AutoPostBack attribute on the checkbox to True.
