| Hi Hans,
|
| Welcome to ASPNET newsgroup.
| Regarding on the question of make the ascx usercontrol access the
| databinding context of its container control when being put in other
| Template databound control (e.g datalist, datagrid....), here are some of
| my understanding and suggestion:
|
| 1. AS for ascx UserControl, itself is a template based control (we
| directly define html in ascx file...), so we can directly put databinding
| expressions in the Ascx file , and then at runtime, the Usercontrol's
| databinding expression will be dynamically compiled and be able to access
| the databinding context of its Container control (datagrid, datalist
...)'s
| binding objects... Fo example, we have a page which contains the
following
| datalist code:
|
| =====================in main aspx page===============
| <asp:DataList ID="DataList1" runat="server" DataKeyField="EmployeeID"
| DataSourceID="SqlDataSource1">
| <ItemTemplate>
| EmployeeID:
| <asp:Label ID="EmployeeIDLabel" runat="server" Text='<%#
| Eval("EmployeeID") %>'></asp:Label><br />
|
| <uc1:MYUC ID="MYUC1" runat="server" />
| </ItemTemplate>
| </asp:DataList>
| </form>
| ===============
|
| we can find that there is a ascx usercontrol in the "itemTemplate" of the
| DataList, then in the "MYUC" usercontrol, we can define the ascx template
| as below:
|
| ==============MYUC.ascx=============
| <%@ Control Language="C#" AutoEventWireup="true" CodeFile="MYUC.ascx.cs"
| Inherits="UC_MYUC" %>
| <asp:Label ID="Label1" runat="server" Text='<%# Eval("EmployeeID")
| %>'></asp:Label><br />
| <asp:TextBox ID="TextBox1" runat="server" Text='<%# Eval("LastName")
| %>'></asp:TextBox><br />
| <asp:Button ID="Button1" runat="server" Text='<%# Eval("FirstName") %>' />
| <asp:LinkButton ID="LinkButton1" runat="server" Text='<%# Eval("Title")
| %>'>LinkButton</asp:LinkButton>
| =============
|
| At runtime, the Databinding expression can correctly reference the
| databinding context and DataItem in the container (DataList)
|
| 2. Also, if you'd like to do programmatic databinding , e.g in DataList's
| "ItemDataBound" event, we can consider define some public Properties
which
| associated with the usercontrol's certain inner Controls , so that we can
| dynamically set value to the usercontrol's inner control in the
DataList
| (or other template databound control)'s ItemDataBound" event.....
|
| Just some of my opinions. Hope helps.
|
| Thanks,
|

| | Hi,
| |
| | I am trying to use a user control as EditItemTemplate in a DataList. It
| | loads fine but I can't figure out how to bind to the data of the
DataList.
| | Here is what I have got so far:
| |
| | //Page_load of my user control
| | protected void Page_Load(object sender, EventArgs e)
| | {
| | IDataItemContainer DataContainer = this.Parent as
| | IDataItemContainer;
| | if (DataContainer != null)
| | {
| | DataList dl = this.Parent.Parent as DataList;
| | mIsNew = false;
| | int ItemIndex = DataContainer.DataItemIndex;
| | object oKey = dl.DataKeys[ItemIndex];
| |
| |
| | This kind of works but I think it's not very clean. Does anybody know
what
| | the proper way is?
| |
| | Thanks
| |
