Hi all i have a repeater control in which i have accordion.I cant access the value from database in accordion.In following code.In accordion i have Button2 and iam trying to assign a value as commandArgument but it always had null value.But if i write same code outside accordion it will works fine <%# DataBinder.Eval(Container.DataItem, "Wid")%>'
I have assigning data source in page_load event.All fields are visible outside the accordion but not in inside the Accordion.
code :

<asp:Repeater ID="Repeater1" runat="server" onitemdatabound="Repeater1_ItemDataBound">
   <ItemTemplate>
   <asp:Image ID="Image1" runat="server" height="25px" Width="25px" ImageUrl='<%# DataBinder.Eval(Container.DataItem,"profilepic")%>' ToolTip='<%#DataBinder.Eval(Container.DataItem,"UserName")%>' />
   <%# DataBinder.Eval(Container.DataItem, "UserName") %>:
    <br/>
       <asp:Label ID="Label1" runat="server" Text=' <%# DataBinder.Eval(Container.DataItem, "WallStatus")%> ' ></asp:Label>
       <asp:Label ID="Label2" runat="server" Text=' <%# DataBinder.Eval(Container.DataItem, "Wid")%> ' Visible="true"></asp:Label><br />
       <div style="background-color:Gray;color:White;width:300px">
       <asp:Repeater ID="Repeater2" runat="server">

            <%# DataBinder.Eval(Container.DataItem, "UserName")%>:
            <br />
