Forms Data Controls :: Updating Dropdownlist Only In A Specific Cell In GridView

I have a situation where i need to update my Dropdownlist templatefield inside a GridView....but only for a specific cell. I have seen codes like this to loop through the whole GridView and update every rows in a specific column, but how do i do it if i only want to update one specific cell ? (If i know the index information of the cell, for example, I know i want to update the dropdownlist on Column 3 and Row 2)

foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
this.WorkTypeDDL = ((DropDownList)row.FindControl("WorkTypeList"));
this.WorkTypeDDL.DataSource = AL;
this.WorkTypeDDL.DataBind();
//more codes blah blah blah//
}
}
