Doug,

What is the return value of myUDF? If you had it return alias.fieldname, would that fix the problem?

Kind Regards,

Mat

When I try to sort on a column, the click event of the header fires, and then it tries to sort on this column. In the SetOrder method of the grid, there is code that tries to decipher what the field and alias is. It doesn't get done correctly because of the UDF in my ControlSource. An example: columns ControlSource = MyUDF(v_SomeView.SomeField). It errs because of this. Can you place some logic here to try and determine the proper field name and alias, or at least check to see if the alias (that was determined) is in use before using RECNO() on it.
