    To prevent users from clicking a tab before the page is loaded I disable the tabstrip serverside:

    myTab.Enabled =

    false;

    and then enable it client-side:
    <script type="text/javascript" language="javascript">

    function EnableTabStrip()

    {

        var tabStrip = <%= myTab.ClientID %>;

        tabStrip.enable();

    }

    </script>

    <body onload="EnableTabStrip();">

    but this doesn't work. It seems I get the object but it receive an 'Object doesn't support this property or method'-error. I tried to change
    var tabStrip = <%= myTab.ClientID %>;

    to:

    var tabStrip = $find('<%= myTab.ClientID %>');

    but this gives me a 'null' is null or not an object-error

    What am I doing wrong? I am using the latest build (2008.1 515)

    Hi Mickey13,

    Please find below a sample code snippet that shows the needed approach.

    ASPX:
    <html xmlns="http://www.w3.org/1999/xhtml">  
    <head id="Head1" runat="server">  
        <title>Untitled Page</title> 
        <link href="Skins/WebBlue/Upload.WebBlue.css" rel="stylesheet" type="text/css" /> 
    </head> 
    <body> 
        <form id="form1" runat="server">  
            <asp:ScriptManager ID="ScriptManager1" runat="server">  
            </asp:ScriptManager> 
     
            <script type="text/javascript">  
            function pageLoad()  
            {  
                var myTabstrip = $find("<%= RadTabStrip1.ClientID %>");  
                myTabstrip.enable();  
            }  
            </script> 
     
            <telerik:RadTabStrip ID="RadTabStrip1" runat="server" OnTabClick="RadTabStrip1_TabClick">  
                <Tabs> 
                    <telerik:RadTab runat="server" Text="Root RadTab1">  
                    </telerik:RadTab> 
                    <telerik:RadTab runat="server" Text="Root RadTab2">  
                    </telerik:RadTab> 
                    <telerik:RadTab runat="server" Text="Root RadTab3">  
                    </telerik:RadTab> 
                </Tabs> 
            </telerik:RadTabStrip> 
        </form> 
    </body> 
    </html> 
     

    Code-behind:
    protected void RadTabStrip1_TabClick(object sender, RadTabStripEventArgs e)  
    {  
        RadTabStrip1.Enabled = false;  
    }

    I tried making a complete example which still gives me the 'null' is null or not an object-error:
    <%@ Page Language="C#" %>
    <%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>Untitled Page</title>
    </head>
    <body onload="enableTabStrip();">
        <form id="form1" runat="server">
            <asp:ScriptManager ID="ScriptManager1" runat="server" />
            <script type="text/javascript" language="javascript">
            function enableTabStrip()
            {
                var myTabStrip = $find("<%= RadTabStrip1.ClientID %>");
                myTabStrip.enable();
            }
            </script>         
            <telerik:RadTabStrip ID="RadTabStrip1" runat="server">
                <Tabs> 
                    <telerik:RadTab runat="server" Text="Root RadTab1" />  
                    <telerik:RadTab runat="server" Text="Root RadTab2" />
                    <telerik:RadTab runat="server" Text="Root RadTab3" />
                </Tabs> 
            </telerik:RadTabStrip> 
        </form>
    </body>
    </html>

    Hello Mickey13,

    Here's your modified code snippet that works as expected.

    <html xmlns="http://www.w3.org/1999/xhtml">  
    <head> 
        <title>Untitled Page</title> 
    </head> 
    <body> 
        <form id="form1" runat="server">  
            <asp:ScriptManager ID="ScriptManager1" runat="server" /> 
            <script type="text/javascript" language="javascript">  
            function pageLoad()  
            {  
                var myTabStrip = $find("<%= RadTabStrip1.ClientID %>");  
                myTabStrip.enable();  
            }  
            </script>           
            <telerik:RadTabStrip ID="RadTabStrip1" runat="server" OnTabClick="RadTabStrip1_TabClick1">  
                <Tabs>   
                    <telerik:RadTab runat="server" Text="Root RadTab1" />    
                    <telerik:RadTab runat="server" Text="Root RadTab2" /> 
                    <telerik:RadTab runat="server" Text="Root RadTab3" /> 
                </Tabs>   
            </telerik:RadTabStrip>   
        </form> 
    </body> 
    </html>  

    pageLoad is a shortcut for the Sys.Application.load event. For details on the matter please refer to the following ASP.NET article.

    Best wishes,
