Question

studio gridview中某两个单元格进行乘法

我想提取第三列的数据和第四列相乘放到同行的第五列中，现在提示取数据的语句错误
for (i = 0; this.GridView1.Rows[i].Cells[3] != null; i++)
{

Int16 a = Convert.ToInt16(this.GridView1.Rows[i].Cells[3].ToString());
Double b = Convert.ToDouble(this.GridView1.Rows[i].Cells[4].ToString());
b=b*a;
string total = Convert.ToString(b);

Answer 1

<table>
<tr>
<td width="50%">
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
</td>
<td width="50%">
<asp:GridView ID="慧余GridView2" runat="server">
</asp:GridView>
</燃游td>
</tr>前段滚
</table>
这样行不？
