       //inside rowdatabound of gridview find the dropdown and bind it like below

  DropDownList ddlQuantity = e.Row.FindControl("ddlQuantity");
     // now you have a ddl
     //{ write a method here to bind the ddl }



       // write this into the selectedindex_change of ddlQuantity

 Control ddlQuantity = (DropDownList)sender as Control;
 GridViewRow gvRow = ddlQuantity.NamingContainer as GridViewRow;

       //now you have the current row of the grid where the dropdown is
       // lets the dropdown selected value is 2 then

Label price =   (Label)gvReplyAdded.Rows[gvRow.RowIndex].FindControl("lblPrice");
Label Amount = (Label)gvReplyAdded.Rows[gvRow.RowIndex].FindControl("lblAmount");
Amount.Text = (Convert.ToInt32(price.Text) * Convert.ToInt32(((DropDownList)sender).SelectedValue)).ToString();

     //here you can get the control of gridview of the same row
