<asp:imagebutton id="imgTest" visible=< %# CType(Container.DataItem, System.Data.DataRowView).Item("NameOfPDF")) % > ImageUrl="graphics/Testing.bmp" runat="server"></asp:imagebutton>The value of the field "NameofPDF" will be blank if it doesn't apply to the row, yet the "VISIBLE" property of the image requires a true/false. How can I get this to work...
