Hello.

I try this code.

I don't have error.

But in the test.gif I have the html format.

E.g.:



The problem is:
System.IO.StringWriter sw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new HtmlTextWriter(sw);

What should I use to insert an image my GridView?

Can you help me? thanks for help.
