Question DataGridView Combo Box Problem

[Progress2007]

Hello

i am using a DataGridView in which i have two unbound DataGrid ComboBox Columns. I bound data in these at run time and each combo box contains data from diffrent dataTables.

Now i want to call funtions when some thing changes in Combo Boxes.

I am giving a detail example.

Suppose my table contains two rows first row contains User, and the second row contains State. I populated User row comboo boxes with UserDataTable and State row combo box with StateDataTable which belongs to same data set.

Now what i want that, when some one changes something in UserCombo Box then UserchangesFunction or event should fire
and if some one changes in StateCombo box then StateChangesFuntion or event should fire..


Please provide me a idea how to do this...
