Hello my code causes the above error. I do not understand, I am trying to get htmlcode of the page to send an email. I have no problem, the mail is okay but the page itself can not be opened and gives the above error. The code is as follows:

StringBuilder str = new StringBuilder();
StringWriter strw = new StringWriter(str);
HtmlTextWriter htmlw = new HtmlTextWriter(strw);
this.Render(htmlw);

Please help...

NO problem is not with the email
it is okay, but when trying to render the page it gives that error.

If you have more than one form tag with Runat=server it will cause error. Actually, aspnet uses server side form element to enforce validation, postbacks etc. If you place 2 server side form it will cause errors.

So just remove the form tag which is not required.

Also if you want to request for two pages, just place the response directly to a container element rather than adding the whole form to the page again. Big Grin | :-D

If it is not clear, let me know.

First of thank you very much for the answer, however it is not clear enough for me...

with container element you mean a table for example? Should I render the table only?

Could you please give an example..

Also it depends on the render command, if I do not run it page is displayed wo problem.

thx alot.

Yes.. You can render only the part of the object you want. Dont render the whole page.

Say your html is placed inside a div. Use div.RenderControl to get the content rather than trying this.Render.

Is this a problem or recursion? If you render the same page that you are in, it will cause an infinite recursion as well.

Thumbs Up | :thumbsup:

Am I right in thinking this is to do with your earlier question about email and html?
If so, then did you add the <form> tag because it complained that the table must be in a form tag?
I tried the response you got from sashidar myself and found the same thing. Are you using master pages? Because I assumed that it had something to do with that when I tried it.

how to group multiple headers in gridview/

17-Nov-09 8:18

Sorry for late response I hate not to answer somebody who is tyring to help me. But I had a busy day.

Yes it is related but no I am not using master page. It is about rendering the page. I am trying to pass the content of current page as email. However when I render the page I receive this error.

I think I am close to get rid of this problem with rendercontrol, however when I use it mycode creates a new div instead of getting the info of the existing div.

Thanks for help.
