你丫的GridView

 机能需求：对数据列表的数据进行拆分合并操作。
拆分：根据用户选择的girdview中的一条或多条数据，动态生成相应个gridview，每个gridview中显示n条改数据（原gridview中有一数量列，n表示其值）；
合并：根据用户选择的动态生成的多个gridview中的数据，合并成一条数据（只数量合并），然后替换原gridview中的选择数据。

好久没玩GridView了，发觉不怎么有感情了。。。
先留下个记号，回头再来总结！
上代码：
前台

1. <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="total" OnRowCreated="GridView1_RowCreated"
2.             >
3.             <Columns>
4.                 <asp:TemplateField>
5.                     <ItemTemplate>
6.                         <asp:CheckBox ID="CheckBox1" runat="server" />
7.                     </ItemTemplate>
8.                 </asp:TemplateField>
9.                 <asp:BoundField DataField="inqmxid" HeaderText="inqmxid" ReadOnly="True" SortExpression="inqmxid" />
10.                 <asp:BoundField DataField="fname" HeaderText="fname" SortExpression="fname" />
11.                 <asp:BoundField DataField="unit" HeaderText="unit" SortExpression="unit" />
12.                 <asp:BoundField DataField="qty" HeaderText="qty" SortExpression="qty" />
13.                 <asp:BoundField DataField="total" HeaderText="total" SortExpression="total" />
14.                 <asp:BoundField DataField="maker" HeaderText="maker" SortExpression="maker" />
15.                 <asp:BoundField DataField="makedate" HeaderText="makedate" SortExpression="makedate" />
16.                 
17.             </Columns>
18.         </asp:GridView>
19.  
20.         <asp:Panel ID="Panel1" runat="server" Height="455px" Width="654px" BorderColor="Silver" BorderStyle="Solid" ScrollBars="Vertical">
21.         </asp:Panel>

后台  动态生成GridView，并添负数据

1. Panel1.Controls.Clear();
2.             for (int i = 0; i < GridView1.Rows.Count; i++)
3.             {
4.                 CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
5.                 if (cbox.Checked)
6.                 {
7.                     int con = Convert.ToInt32(GridView1.DataKeys[i].Value);
8.                     if (con > 0)
9.                     {
10.                         DataTable dt2=dt.Clone();
11.                         for (int j = 0; j < con; j++)
12.                         {
13.                             dt2.Rows.Add(dt.Rows[i].ItemArray);
14.                             dt2.Rows[j]["total"] = "1";
15.                         }
17.                         GridView grv = new GridView();
18.                         grv.Width = Unit.Pixel(500);
19.                         grv.RowCreated+=new GridViewRowEventHandler(grv_RowCreated);
21.                         Panel1.Controls.Add(grv);
22.                         grv.DataSource = dt2;
23.                         grv.DataBind();
24.                     }
26.                 }
27.             }

动态插入CheckBox

1. protected void grv_RowCreated(object sender, GridViewRowEventArgs e)
2.         {
3.             GridViewRow row = e.Row;
4.             if (row.RowType == DataControlRowType.Header)
5.             {
6.                 TableCell cell = new TableCell();
7.                 cell.Wrap = Wrap;
8.                 cell.Width = Unit.Pixel(50);
9.                 cell.Text = "<label>选择</label>";
10.                 row.Cells.AddAt(0, cell);
11.             }
12.             else if (row.RowType == DataControlRowType.DataRow)
13.             {
14.                 TableCell cell = new TableCell();
15.                 cell.Wrap = Wrap;
16.                 CheckBox cb = new CheckBox();
17.                 cell.Width = Unit.Pixel(50);
18.                 cb.ID = "ItemCheckBox";
19.                 cell.Controls.Add(cb);
20.                 row.Cells.AddAt(0, cell);
21.                 
22.             }
23.         }

完事，走人。
