Solution of "Cannot get inner content of your DIV because the contents are not literal. "

if you want to send your div inner htnl as a string and you are finding error "Cannot get inner content of DIV because the contents are not literal."

Solution is :-

StringWriter sw = new StringWriter();
HtmlTextWriter h= new HtmlTextWriter(sw);
objDiv.RenderControl(h);
string str= sw.GetStringBuilder().ToString();

* objDiv is your DIV Id.

Thanks
