Programatically Change Datagrid column type?

[Dan Hartshorn]

VS.NET 2003, C#, Windows Server 2003. I have a datagrid and I want the
last column to be either an EditCommandColu mn or a template column,
depending on a value I have. The value changes for each row. So some
rows will have an EditCommandColu mn, others just a text message in the
last column. Is this possible? I am already using the ItemDataBound
method to perform some function on each row, but I can't seem to
change the datagrid's column type programatically .

I tried some inline C#:

<%if(myBooValue ){%>
<asp:TemplateCo lumn...
<%} else {%>
<asp:EditComman dColumn...
<%{%>

But I received a runtime error: cannot use control block in that
context. Even if that worked, I'm looking for a way to do it cleanly
in the code-behind.

Another idea I had was to define both columns in the aspx datagrid,
then show-hide them in the code-behind depending on my value for that
row. But I can't figure out how to programatically ID the columns to
show or hide them.

Thanks,
Dan
