Answer 1

The GridView control automatically html-encodes everything, but there are a couple ways you can turn it off. If you have the image field declared in the aspx page, the easiest option is to just set the HtmlEncode property to false.

<asp:BoundField DataField="image" HtmlEncode="false" />

If this isn’t feasible in your case, you can ‘undo’ the html encoding for these cells on the GridView’s RowDataBound event.

Private Sub gridview1_RowDataBound(ByVal sender As Object, ByVal e As   System.Web.UI.WebControls.GridViewRowEventArgs) Handles gridview1.RowDataBound
    e.Row.Cells(1).Text = Server.HtmlDecode(e.Row.Cells(1).Text)
End Sub

I’m assuming from your example that your GridView has 2 columns and the image column is the second one, hence Cells(1) in each row. Hope this helps!
