:  |  Link Button problem.
Ok...I'll bet it's good to see an actual issue on here.
Today I was tasked with modifying some code. We need to make a link button appear, but only when certain criteria is met.
Due to the nature of the functionality, I'm using a DataList, and so I'm populating it with DataBinder.Eval(Container.DataItem, "MY_FIELD").
That piece works fine.
What I want to do, though, is use something similar to that to essentially toggle a LinkButton (again, it's a functionality thing, and there's too much to re-write at this point).
I've tried various things.
Anyone got any ideas?
Basically, what I want is this:
If (DataBinder.Eval(Container.DataItem, "MY_FIELD") = "A") Then
' Show the Link Button
End If

Should the equals sign (=) be doubled like this:
If (DataBinder.Eval(Container.DataItem, "MY_FIELD") == "A" Then Show the Link Button
End If
Perhaps you should be using all lower-case.
In Perl, the equals sign should be "eq" to check a non-numeric field.

This message has been edited.I was using VB.NET in an ASP.NET app.
I figured it out yesterday. Here's the solution:
<asp:LinkButton ID="MyLinkButton" runat="server" CommandName="reopen" Font-Bold="true" Font-Italic="true" Text="Re-Open" Visible=<%# IIF (Container.DataItem("STATUS") = "Closed","true","false") %> />
That did the trick. Took me three days to figure that out. That's way too long.
