validators not firing server-side

am 07.01.2008 12:21:43 von J055

Hi

I have a Formview control in a UserControl. The server-side validation is
not working, i.e. the events are not firing when a button control which
causes validation is fired or even when Page.Validate() is explicitly
called.

I'm loading the FormView as an IBindableTemplate as in this article but I
don't think this is the reason for the validation not working.
http://www.developerfusion.co.uk/show/4721/

I have a couple of custom validators in the user control which bubble the
events to the parent page. These don't fire. However I have tested in
another simpler version of the page and they do fire.

What can I do to determine why the validation doesn't work? What can cause
it to stop working? How do I debug?

Thanks
Andrew

Hi Andrew,

As for the article you mentioned, it use a usercontrol + a wrapper formview
to provide dynamic bindable template. The FormView in the usercontrol
should not be used. I think you've used the dynamic loaded template in the
main page(with some certain databound control), correct?

I have performed a simple test with the following page, it seems the
validator can correctly validate the textbox(both of them are within the
usercontrol...).

Here is the source code of the test page&user control

=========BindableTemplate.ascx=========
<%@ Control %>

ErrorMessage="RequiredFieldValidator"
ControlToValidate="TextBox1"
EnableClientScript="false">

CausesValidation="false"/>

=======================

=====test aspx page============

=======code behind=============
..........

protected void Page_Init(object sender, EventArgs e)
{
FormView1.ItemTemplate =
LoadBindableTemplate("~/BindableTemplate.ascx");
}

protected void Page_Load(object sender, EventArgs e)
{

}
protected void btnTree_Click(object sender, EventArgs e)
{
Page.Validate();
}

IBindableTemplate LoadBindableTemplate(string path)
{
Control c = Page.LoadControl(path);
FormView fv = c.Controls[0] as FormView;

if (fv == null) throw new Exception("invalid template file");

return (IBindableTemplate)fv.ItemTemplate;
}
===========================

please feel free to let me know if there is anything else different in your
case.
