Checkbox alert

[LeoLionHeart]

Hi there, any help would be greatly appreciated.

I have a server side checkbox on my web form called chkConfirm.
What I want the user to do is when the check box is tick for a confirm/alert message box to appear asking "are you sure you want to delete?" Yes/No.

If the user chooses No then the check box becomes unticked. If Yes the check box stays ticked.

Any ideas? - I know I have to use JScript for this but am unsure how to go about doing this?

The problem with the checkbox list is that you will not be able to determine what checkbox in the list was checked.

No it is only one checkbox which is called chkConfirm

Oh ok sorry, I thought it was a checkboxlist.

You can try something like this:

Dim msg as String
msg = "return confirm('Are you sure you want to delete?');"
<YourCheckBox>.Attributes.Add("onclick", msg)

Where should I place this code - In the page load event or Checked changed event. This checkbox is a server side control?

Thanks.

The page_load event

A better solution would be this:

<script>
   function test()
   {
      var i;
      if (document.forms[0].CheckBox1.checked == true)
      {
         i = confirm('Are you sure you want to delete?'); 
         if (i == false)
         {
	    document.forms[0].CheckBox1.checked = false;
         }
       }
   }//end function test()
</script>

add the function between the script tags in the HEAD tags of your HTML. Then in your codebehind do this (Page_Load):

   <YourCheckBox.Attributes.Add("onclick", "test();")
