Hi Josh.

Here's my problem:
I have a grid that is bound to one table. In the fourth column, I have a combobox. I want to populate the combobox with another table. Depending on what is in column one, I want to filter the values in the combobox for that row.

You may want to check out my web site and download the white paper and code samples from my "Effective Techniques for Using a Combo in a Grid" presentation.
