    I would like to see if it's possible to pass the value from a container.data with rad button in an asp.repeater control.


    <script type="text/javascript">
    function open_windowtemplate_AddSection(sender, args) {
    var button = sender.get_id();


    <asp:Repeater ID="rpt_Channel" runat="server" OnItemDataBound="rpt_Channel_ItemDataBound">
    <td colspan="4" class="MainLineItem">
    <div style="float:left;">&#9632; <asp:Label ID="lbl_ChapterName" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "Chapter")%>'></asp:Label></div>
    <div style="float:right">
    <asp:ImageButton ID="imgbtn_AddSection" runat="server" AlternateText="Click to add section" ImageUrl="~/Includes/images/green_plus_add.png" Height="20px" CommandName="Add" />
    <telerik:RadButton ID="radbutton_AddSection" runat="server" Text="+" CommandArgument='<%Databinder.Eval(Container.DataItem, "Channel_ID") %>'
    ButtonType="StandardButton" OnClientClicked='open_windowtemplate_AddSection' AutoPostBack="false">

    Hello Steve,


    I am not sure what is the exact difficulty with the case here. 


    The only issues I see is the alerted value in the open_windowtemplate_AddSection click hander of RadButton. And they are:


    1.  $(button) would not return you the proper jQuery element. get_id returns you only the id, not the selector to use for jQuery. Make sure to modify that so that it works. For example, $("#" + button).
    2. Even if you get the proper jQuery element there is no commandarguments property that would return you the CommandArgument assigned in the RadButton control. 

      For that, there is the client-side API of the RadButton reference: http://docs.telerik.com/devtools/aspnet-ajax/controls/button/client-side-programming/overview. And the method is get_commandArgument().

      I suggest you testing with this piece of code:
      function open_windowtemplate_AddSection(sender, args) {

    If this does not help you with the case. Please, provide a simple, locally runnable markup of the situation you have and elaborate more on the difficulty you have with it.
