I assume the property you're looking for is GridViewRow.RowIndex. To get the reference to the row from the SelectedIndexChanged event from your DropDownLis(s), you can use it's NamingContainer property:

private void DropDownList1_SelectedIndexChanged(object sender, System.EventArgs e)
{
   DropDownList ddl = (DropDownList)sender;
   GridViewRow row = (GridViewRow)ddl.NamingContainer;
   int rowIndex = row.RowIndex;
   // if you want to get the reference to the other DropDown in this row
   DropDownList ddl2 = (DropDownList)row.FindControl("DropDownList2");
}

You can handle SelectedIndexChanged event of DropDownList.

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
        GridViewRow gvr = (GridViewRow)((DropDownList)sender).Parent.Parent;
        string rowNumber= GridView1.DataKeys[gvr.RowIndex].Value.ToString();
}
