Hi, While working on the contact forms ensure that the file AclInv.aspx is not changed. We were not able to add users and later we traced the root cause to this file becoming corrupt. We then had to get this file from Microsoft to get it working again. Regards, Scott www.sharepointrangers.com

Hi, I am having an issue with ARF Contact Form in that i don't see the <template> tag, i have done anything wrong? I have registered the controls at the top of the page and the ARF is deployed on the site? Thanks Simon

Simon, I'm not sure what you mean by 'I don't see the <template> tag'? The <template> is actually a property of the TemplatedControl and contains the control template. Any HTML (or server controls) you place in that tag will be rendered. --Vince

Hi, I have created a form using the ARF contact form, and I have matched up my list columns to the controls on the form, but everytime i click on the submit button it goes the failed to send message panel. Is there anyway to see why it is failing? Thanks Simon

Simon, ARF writes all its errors to the Debug console. If you use DebugView (from TechNet), then you should see the errors. HTH, Vince

Nice looking functionality. Can the controls be accessed through C# code on the aspx page. I tried adding the following which works on an ASPX page added through Sharepoint designer. But I was not able to access the controls from your sample. <script Language="c#" runat="server" type="text/c#"> private void Category_SelectionChanged( object sender, System.EventArgs e ) { idSubject.Text = "Test"; } </script> Thanks. -Art

Aruro, Not in that way as their NamingContainer is different. You should be able to change your code to... ((TextBox)idContactForm.FindControl("idSubject")).Text = "Test"; Where idContactForm is the <ARF:BasicContactForm /> --Vince

At the second source, please make the following corrections : <ARFFields:RichTextField FieldName="HtmlOneunat="server"/> to <ARFField:RichTextField FieldName="HtmlOne" runat="server" /> (two times) Arf may be nice or bad, but we'll never know that, due to lack of documentation ...

Good site, admin.

I'm not clear what this means "Once this is created you can add the ARF BasicContactForm to the PlaceholderMain placeholder within your layout"... I add the HTML code where? I've not altered HTML of Sharepoint pages before. Thank you.
