Pamela,

Another way is to create a class of the control with the code in it. When you change the ColumnCount property of your grid, by default each column is poplated with a generic textbox. You can then scan through your columns and add the subclassed control to each column...

For each oColumn in Thisform.oGrid.Columns
oColumn.AddObject("myTextBox1","myTextBox")
oColumn.CurrentControl="myTextBox1"
oColumn.myTextBox1.ControlSource="SomeControlSource"
oColumn.ControlSource="SomeControlSource"
Endfor

Before you can do this, you must have defined the class "myTextBox" and have that classlibrary loaded. If you use this method, you can change any method/event to meet your needs.
