！我有一个嵌套DataList，我想DataList在button事件上绑定内部，但它不起作用，有人知道吗？

DataList2.FindControl("DataList3").DataBind();

将此代码用于Bind内部DataList：

protected void DataList2_ItemDataBound(object sender, DataListItemEventArgs e)
{
    if ((e.Item.ItemType == ListItemType.Item) || 
             (e.Item.ItemType == ListItemType.AlternatingItem))
    {
        // get inner datalist
        DataList dl3 = e.Item.FindControl("DataList3") as DataList;

        // bind inner datalist with data source
        dl3.DataSource = dt; // DataTable that contains data
        dl3.DataBind();
    }
}

注意： 确保您已OnItemDataBound="DataList2_ItemDataBound"像这样输入此事件：

<asp:DataList ID="DataList2" runat="server" OnItemDataBound="DataList2_ItemDataBound">

Try to cast it with datalist

((DataList)DataList2.FindControl("DataList3")).DataBind();
