OnClick vs OnClientClick for an asp:CheckBox?

Question

Does anyone know why a client-side javascript handler for asp:CheckBox needs to be an OnClick=\"\" attribute rather than an OnClientClick=\"\" attribute, as for asp:Button?<

Answer 1

You can do the tag like this:

The .checked property in the called JavaScript will be correct...the current state of the checkbox:

  function checkchanged(obj) {
      alert(obj.checked)
  }
