Get htmltextbox error message/code

[Girard Loic]

Hi

Is there a way to get an error message(or code)  when the contents of a htmltextbox isn’t supported (eg: <TABLE> tag)?  

Many thanks

Hi Girard Loic,

To check whether the HtmlTextBox would be able to handle the content you set to its value, you should use the IsValidXHTML method of the HtmlTextBox processing instance.
You can do that check either in the ItemDataBinding event of the item e.g.:

private void htmlTextBox1_ItemDataBinding(object sender, EventArgs e)
   {
       var box = (Processing.HtmlTextBox)sender;
       if (box.IsValidXhtml((string)row[0]))
       {
           box.Value = row[0];
       }
       else
       {
           box.Value = StrippedXhtml;
       }
   }

or directly in the HtmlTextBox expression e.g.:

"=Iif(ReportItem.IsValidXhtml('content_here'), 'true_part', 'false_part')"
