Question

Ive got a gridview with an itemtemplate that has a hyperlink control in it. I want to hide a hyperlink control if its item in the database returned null:

  <ItemTemplate>
                                   <asp:HyperLink ID="hlSugar" Visible=<% DataBinder.Eval(Container, "DataItem.CaseID")==null %> ToolTip="View the issue in SugarCRM." Target="_blank" runat="server" NavigateUrl='<%# "http://myPath&record=" + DataBinder.Eval(Container, "DataItem.CaseID") %>' Text="Issue"></asp:HyperLink>
                            </ItemTemplate>

Not sure on the syntax can I do

Visible = <% iif(databinder.eval(container, "dataItem.caseid")==null, false, true) %>

Not sure how to get the syntax correct. I basically want to check if my `DataItem.CaseID is null and hide this field if it is.

Answer 1

I ended up using this:
Visible='<%# Eval("SugarCaseID") != DBNull.Value %>'
