Hi everyone!! Here&#039;s a tricky one: I have a datagrid that uses a TemplateColumn with a CheckBox WebControl inside. I want to use client-side JavaScript to validate a condition (but I&#039;ll be happy with an alert("Hello World!"); instead) when the checkbox is clicked. Then, I want the form to be posted to the server. Whew.<BR><BR>I&#039;m having a tricky time with the AttributeCollection available in the CheckBox control. I suspect my problem is caused by my use of it in a DataGrid. I&#039;ve disabled the CheckBox&#039;s autopostback statement and I&#039;m setting:<BR> checkbox.attribute("validate") = "validate();" <BR>but no luck! Any ideas out there? Thanks in advance!<BR>
