    Hi All,

    I have used telerik tree view control in my code to select users as info and to field.

    <telerik:RadTreeView ID="tvToDirectorate" runat="server" CheckChildNodes="True" OnNodeClick="tvToDirectorate_NodeClick"

                        OnDataBinding="tvToDirectorate_DataBinding" OnNodeDataBound="tvToDirectorate_NodeDataBound1"

                        DataFieldParentID="lParentID" DataTextField="sDisplayName" DataValueField="lValueID"

                        DataFieldID="lValueID" OnNodeExpand="tvToDirectorate_NodeExpand" >


    <table cellpadding="0" cellspacing="0" width="100%" align="right">


    <td style="width: 50%">

          <asp:CheckBox ID="rdTo" name='<%# Container.Value %>' runat="server" GroupName="toinfo" Visible="true" />


          <td style="width: 50%">

          <asp:CheckBox ID="rdInfo" name='<%# Container.Value %>' runat="server" GroupName="toinfo" Visible="true"/>






    The checkboxes are dynamically creating name with different IDs. Now I want following.

    1. I want to access name in JavaScript so that I would be able to select one checkbox as “Info” or “To”. Currently at a time both can be selected but that’s not good.
    2. Secondly if I am using radio button that is a good choice. But I want to deselect when double click radio button. And I cannot be able to access the radio button on run time.


    On main window I am using telerik grid control where using

    <EditFormSettings EditFormType="WebUserControl" PopUpSettings-Modal="true" PopUpSettings-Width="800px" UserControlName="~/UserControls/ucMailRecipient.ascx">

    <PopUpSettings Modal="True" Width="800px" />




    When click on “Add Recipients” popup window with “Modal=True” open where we selects the users.

    We cannot use “document.getElementById("rdTo").checked;” since its dynamically creating.

    And may be name should like “$ctl_TreeView_”  etc may be.

    Please if anybody helps to tackle this problem. Many thanks for your help.

    I'm not sure I fully understand the problem, but in general you can use this in ASP.NET to get the dynamically generated IDs that ASP.NET produces:

    <%= rdInfo.ClientID %>

    This will result in the correct HTML ID being output so that you can use code like "document.getElementById" (or even more handy, use jQuery and $() selectors).
