    I am using Telerik Winforms Gridview and the Column expression.

    I am trying to return data from a field (column) in a gridview using a IIF statement.
    The below works:
    IIF(customer_name='Bills Hairy Mess','win','lose')

    The below crashes the form:
    IIF(customer_name='Bills Hairy Mess',cust_ref_1_BOL,'lose')
    I also tried
    IIF(customer_name='Bills Hairy Mess',[cust_ref_1_BOL],'lose')

    cust_ref_1_BOL is a valid field name and is pickable from within the expression editor under 'fields'

    Is the above possible?

    Thank you,

    Hello Joe,

    I'm responding here to close this forum thread as this is a duplicate of a support ticket for the same issue.

    For folks visiting the forums looking for a similar answer,you can indeed use a field name with an IIF expression. You just have to make sure there are no quotes around the field name.

    For example, I created a "Can Call" calculated column using the following IIF expression on a Northwind Customers table's Country and Phone fields

    IIF(Country = 'USA' , Phone  , 'no calls' ).

    That expression will yield the following result:

    Indeed you can.

    You do need to make sure that the field is in the columns list for the grid, which is what I was doing wrong.

    It can be not visible, but needs to be there (obviously).

    I had a need to exclude some columns from a export but still use them on the screen for calculations, this works fine by setting their visibility to false right before exporting.

    Thanks Lance --
