I think you're looking for the RowUpdating event for the gridview. The code below is from a project a I worked on a couple of years ago, where I had to grab the value from a combo-box within a gridview. Hopefully this will get you closer to a solution.

    protected void gvReconciliation_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
         DropDownList dropDownListUser = gvReconciliation.Rows[e.RowIndex].FindControl("ddlSourceEdit") as DropDownList;
         e.NewValues["source"] = dropDownListUser.SelectedItem.Text;
    }

My controls were bound to an object data source so that's why you see the e.NewValues["source"] in there. "Source" was the bound column name in my ObjectDataSource.
