ASPxGridView - How to implement conditional DataItemTemplate

This I love being a devexpress customer - the sky is the limit. Developing user friendly application with devexpress is amazing and I'm still amazed regularly. I implemented the GetRender solution together with this demo sample https://demos.devexpress.com/ASPxGridViewDemos/Templates/Template.aspx and those 2 combined really deliver:
when a product photo is in the database, a link is displayed to show it in popup on demand, and when no photo is present, user won't get bothered with a link to nothing.
Printscreen attached (y)

Thank you very much Mike!

Hello Mike,

I've solved the task with two approaches:

ASPx
<dx:ASPxGridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False"
     DataSourceID="SqlDataSource1" KeyFieldName="CustomerID">
     <Columns>
          <dx:GridViewDataTextColumn FieldName="CustomerID" ReadOnly="True"
               VisibleIndex="0">
          </dx:GridViewDataTextColumn>
          <dx:GridViewDataTextColumn FieldName="ContactName" VisibleIndex="1">
               <DataItemTemplate>
                    <%# GetRender(Eval("Country")) %>
               </DataItemTemplate>
          </dx:GridViewDataTextColumn>
          <dx:GridViewDataTextColumn FieldName="Country" VisibleIndex="2">
               <DataItemTemplate>
                    <%# Eval("ContactName").ToString().Contains("a") ? "<a href="javascript:View('')">" + Eval("ContactName") + "</a>" : "something else" %>
               </DataItemTemplate>
          </dx:GridViewDataTextColumn>
     </Columns>
</dx:ASPxGridView>

The "ContactName" column DataItemTemplate is:
     <%# GetRender(Eval("Country")) %>
The code here calls the server-side method that returns the rendering.
The server-side method is:

C#
public string GetRender(object data){
string str = data.ToString();
if(str.Contains("a"))
return string.Format("<a href="javascript:View('')">{0}</a>", str);
return "something else";
}

The "Country" column DataItemTemplate is:

ASPx
<%# Eval("ContactName").ToString().Contains("a") ? "<a href="javascript:View('')">" + Eval("ContactName") + "</a>" : "something else" %>

The condition operator ?: (http://msdn.microsoft.com/en-us/library/ty67wk28(v=vs.80).aspx) returns one of the strings.

Please note, all the expressions are data-binding ones (http://msdn.microsoft.com/en-us/library/bda9bbfx(v=vs.71).aspx)

Please let us know whether either of the options meets your task requirements.
