Dynamic ListView Column

Hello, I've got a standard ListView control setup that displays data from a SQL database based on a query that I provide to it.

Along with the columns I indicated in the creation of the ListView control, I need to create 1 dynamic column that holds data from one of two other columns in the ListView.  Here is the logic:

My custom column will be called Column3.  If something exists in the first column, add it to the Column3 ELSE if something exists in the second column add it to Column3.

The data for all of the columns except this dynamic column (Column3) would be drawn directly from the database.

Code examples would be great.

Also, would it be possible to add such a dynamic column to a GridView?

I'm using ASP.NET (C#) 3.5 Framework.

Thank you in advance.

Hi,

You can do it right from your SQL query, something like this

SELECT Field1, Field2,
CASE
     When Field1 Is Not Null THEN Field1
     When Field2 Is Not Null THEN Field2
     Else ' '
END As Field3
FROM YourTable
