I'm trying to set the display member for a combox to the name of an alias column.  However, whenever I tab out of the "display menber" box the name reverts to none.  It will not allow me to enter in the name of the alias column created in the SQL query.  I'm using VS 2008 is there any work around for this, or am I missing something.

What do you have set for the DataSource name?  What is the name of the Display Member Column?

Only if you want people to try to help you.

You don't have to post the entire program, but, any program code related to creating the datasource would help.  

If you are setting these values through the properties window,then, there might not be any code to post.

That's why I asked, because I am trying to adjust the settings in the properties window.  I data bounded a combobox to a TableAdapter. This tableAdapter has the query in question.  In this query is a subquery with an alias.  I'm trying to use this alias to display info in the combo box.

OK, not much I can do for you, sorry.  I bind my controls through datasets I create in code.  Perhaps someone else will be able to comment.  I don't think it is possible to bind a control to a subquery within a query, but then, I've never tried.

I found a programitic solution. In VS 2008 this was the solution that worked for me

comboBox.DisplayMember = "Sql_Query_Alias_name"

This can be inserted anywhere; however, I inserted it within the load event for the form and it worked perfectly.
