"...must be placed inside a form tag with runat=server" error

Hi there,

I am trying to send via email some information I obtained through the use of
a Wizard. The information is presented to the user on a UserControl called
ucOrderInfo. I placed the following code within another user control called
ucWizardManager to enable that (ucWizardManager contains ucOrderInfo).

TextWriter writer = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(writer);

ucOrderInfo.RenderControl(htw);
string body = htw.ToString();
SendMail(Guest.Email, writer.ToString());

......

I also override VerifyRenderingInServerForm(Control control) on the default
page of the website (its DNN framework), and added to Default.aspx "
EnableEventValidation=false ". It solved the error I was getting for most of
the controls in ucOrderInfo, but when I added the GridView I received this
error: >>> GridView must be placed inside a form tag with run at=server <<<

I did some reading and they all suggest that I do what I've already did. At
this point I have no Idea how to solve it. I could use a useful advise on
how to render the information stored in a UserControl (or any other
control), apply CSS RULES to it, and send it via mail.

Thanks, David
 
Hello David,

I can reproduce the issue. And after I modify my project following this
link
http://rstew.blogspot.com/2007/10/gridview-must-be-placed-inside-form-tag.ht
ml, I managed to resolve it in my side.

The default implementation of overrided VerifyRenderingInServerForm looks
like,

public override void VerifyRenderingInServerForm(Control control)
{
base.VerifyRenderingInServerForm(control);
}

We need to change it to

public override void VerifyRenderingInServerForm(Control control)
{
return;
}

I notice you mention you have overrided the VerifyRenderingInServerForm
method. But did you change the default implementation? Calling the base
VerifyRenderingInServerForm will still cause this problem.

Hope this helps!

Hi Ji,

yes I guess I should have implemented the original override of the method.
It works fine now.

thank you so much.
