Empty columnI need to check to see if a column in a repeater or datagrid control is empty. I tried this but got the error that expression is expected: <%If # DataBinder.Eval(Container.DataItem, "linkURL1") ="" %> <a href="javascript:openWindow('<%# DataBinder.Eval(Container.DataItem, "linkURL1") %>');"><%# DataBinder.Eval(Container.DataItem, "linkText1") % ></a> <%End if %>This is my Repeater Code: ------------------------- <ASP:Repeater id="RepeaterPageText" runat="server" DataSource="<%# Data.dataClass.GetPage(IntCourseNumber,IntLessonNumber,IntPageNumber) %"> <ItemTemplate> <a href="javascript:openWindow('<%# DataBinder.Eval(Container.DataItem, "linkURL1") %>');"><%# DataBinder.Eval(Container.DataItem, "linkText1") % ></a> <br /><a href="javascript:openWindow('<%# DataBinder.Eval(Container.DataItem, "linkURL2") %>');"><%# DataBinder.Eval(Container.DataItem, "linkText2") % ></a> </ItemTemplate></ASP:Repeater> Thanks so much There are a few ways to approach this. One is:
<ItemTemplate> <asp:Label runat=server Visible='<%# DataBinder.Eval(...) <> "" %>'> <other stuff here /> </asp:Label> </ItemTemplate> So then the label won't render (and neither will its contents) if your condition fails. -Brock DevelopMentor http://staff.develop.com/ballen Show quoteHide quote > Hi, > > I need to check to see if a column in a repeater or datagrid control > is empty.
