AutoGenerateSelectButton="True" CellPadding="4" ForeColor="#333333" GridLines="None" OnSelectedIndexChanging="GridView1_SelectedIndexChanging" EmptyDataText="未录入">

<PagerStyle HorizontalAlign="Right" BackColor="#FFCC66" ForeColor="#333333"/>

<PagerSettings Mode="NextPreviousFirstLast" FirstPageText="第一页" PreviousPageText="上一页" NextPageText="下一页" LastPageText="最后一页" />

<Columns>

<asp:BoundField DataField="ckdh" HeaderText="出库单号" SortExpression="ckdh" />

<asp:BoundField DataField="sj" HeaderText="出库价格" SortExpression="sj" />

<asp:BoundField DataField="sl" HeaderText="出库数量" SortExpression="sl" />

</Columns>

<SelectedRowStyle ForeColor="Navy" BackColor="#FFCC66" Font-Bold="True" />

C#后台代码:
protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs a)

{

TextBox1.Text = GridView1.Rows[a.NewSelectedIndex].Cells[1].Text.ToString();

TextBox2.Text = GridView1.Rows[a.NewSelectedIndex].Cells[2].Text.ToString();

TextBox3.Text = GridView1.Rows[a.NewSelectedIndex].Cells[3].Text.ToString();

TextBox4.Text = GridView1.Rows[a.NewSelectedIndex].Cells[4].Text.ToString();

TextBox5.Text = GridView1.Rows[a.NewSelectedIndex].Cells[5].Text.ToString();

TextBox6.Text = GridView1.Rows[a.NewSelectedIndex].Cells[6].Text.ToString();

TextBox7.Text = GridView1.Rows[a.NewSelectedIndex].Cells[7].Text.ToString();

TextBox8.Text = GridView1.Rows[a.NewSelectedIndex].Cells[8].Text.ToString();

TextBox9.Text = GridView1.Rows[a.NewSelectedIndex].Cells[9].Text.ToString();

Session["shuliang"] = Convert.ToInt32( TextBox9.Text);

//TextBox10.Text = GridView1.Rows[e.NewSelectedIndex].Cells[10].Text.ToString();

//TextBox11.Text = GridView1.Rows[e.NewSelectedIndex].Cells[11].Text.ToString();

// TextBox1.Text = GridView1.Rows[e.NewSelectedIndex].Cells[1].Text.ToString();

//Response.Write("<h1>" + sl + "</h1>");
//bh = GridView1.Rows[e.NewSelectedIndex].Cells[2].Text.ToString(); //得到选中行第二个单元格的文本
}
