这样的模板列，点击“编辑”的时候为什么没有反应？

点击编辑需要触发EditCommand,参考：<%@ Import Namespace="System.Data" %>
 
<html>   <script language="C#" runat="server">
 
      DataTable Cart = new DataTable();
      DataView CartView;

            Cart.Columns.Add(new DataColumn("Qty", typeof(String)));
            Cart.Columns.Add(new DataColumn("Item", typeof(String)));
            Cart.Columns.Add(new DataColumn("Price", typeof(String)));
            Session["ShoppingCart"] = Cart;

            for (int i = 1; i <= 4; i++)

解决方案 »

  1.   

    主要问题是：你没有设置edititemtemplate
    <asp:TemplateColumn HeaderText="费用金额（元）">
    <ItemTemplate>
    <%# DataBinder.Eval(Container.DataItem,"mny_money")%>
    </ItemTemplate>
    <EditItemTemplate>
    <asp:TextBox Runat="server" ID="newmoney" Text='<%# DataBinder.Eval(Container.DataItem, "mny_money") %>'>
    </asp:TextBox>
    </EditItemTemplate>
    </asp:TemplateColumn>
      

  2.   

    must handle datagrid_editcommand,
      

  3.   

    设置datagrid的事件属性为DataGrid_EditCommand;
    private void DataGrid_EditCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
    {
    DataGrid.EditItemIndex = e.Item.DataSetIndex;
    DataGrid.DataSource = "数据源";
             DataGrid.DataBind();
    }
      

  4.   

    private void DataGrid2_ItemCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
    {switch(e.CommandName)
      {
       case "update":
    //update 语句
       case "edit": this.DataGrid2.EditItemIndex=e.Item.ItemIndex;
              this.DataGrid2.DataBind();   }
    }
