请教：datagrid嵌套datagrid后，子datagrid的update,edit,delete事件，如何增加上去呢？

Question

//外层的datagrid绑定方法：
private void dg0_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
               ......
               DataGrid dg=new DataGrid();//内层datagrid
               ......
               if(e.Item.ItemType==System.Web.UI.WebControls.ListItemType.Item || e.Item.ItemType==ListItemType.AlternatingItem)
{
e.Item.Cells[1].Controls.Add(dg);
}
               dg.EditCommand+=new DataGridCommandEventHandler(this.dg_EditCommand);
               //??????上边一句，我增加后，在方法外写private void dg_EditCommand}
}
private void dg_EditCommand(object sender, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{

dg.EditItemIndex=e.Item.ItemIndex;
                            ......
                   }
但dg_EditCommand无法调用dg了。我应该如何写，才对呢？？？请大侠高手指点！！！！！！！

Answer 1

don't use ItemDataBound event, use ItemCreated event instead, but do the databinding the outer DataGrid's ItemDataBound event handler

Answer 2

<asp:DataGrid id="dg0"
OnItemCreated="dg0_ItemCreated"
OnItemDataBound=" dg0_ItemDataBound"private void dg0_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if(e.Item.ItemType==System.Web.UI.WebControls.ListItemType.Item || e.Item.ItemType==ListItemType.AlternatingItem)
{
       DataGrid dg=new DataGrid();//内层datagrid
dg.ID = "mynestedGrid";
e.Item.Cells[1].Controls.Add(dg);
  dg.EditCommand+=new DataGridCommandEventHandler(this.dg_EditCommand);
          
}
              
}
private void dg0_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
               if(e.Item.ItemType==System.Web.UI.WebControls.ListItemType.Item || e.Item.ItemType==ListItemType.AlternatingItem)
{
DataGrid dg = e.Item.FindControl("mynestedGrid") as DataGrid;
//call dg.DataBind() if you need to
}
}

Answer 3

为什么我跳出private void dg0_ItemCreated后
构造:
private void dg_EditCommand(object sender, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{

dg.EditItemIndex=e.Item.ItemIndex;
                            ......
                   }
输入dg.还是没有智能跟踪，也就是说，还是没法调用局部的dg呢？？

Answer 4

private void dg_EditCommand(object sender, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{DataGrid dg = sender as DataGrid;
or

DataGrid dg = e.Item.FindControl("mynestedGrid"); dg.EditItemIndex=e.Item.ItemIndex

Answer 5

在下写了一个测试，发现dg0_ItemCreated方法运行后，并没有将dg加入到主datagrid中去呀？是怎么回事呢？

how does your page look like?? where did you bind the nested datagrid?private void dg0_ItemDataBound(object sender, DataGridItemEventArgs e)

}}where are these code located??SqlConnection conn=new SqlConnection("Data Source=localhost;Initial Catalog=tdb;uid=sa");
string yyjs="select name,age from userinfo";
