    Hello everyone,

    I'm trying to make a sample page to see how RadWindow could be used.

    I dragged a RadScriptManager with ID = RadScriptManager1, then added a RadWindowManager to the page.

    and wrote the following code to pop-up the window when needed with some Info.

    // I tried both ways  
     
    RadScriptManager.RegisterStartupScript(this, RadScriptManager1.GetType(), "ALERT", "radalert('Testing RadWin!', 330, 100);", true); 
     
    //============================================================== 
     
    ScriptManager.RegisterStartupScript(this, RadScriptManager1.GetType(), "ALERT", "radalert('Testing RadWin!', 330, 100);", true); 

    but I'm getting the following javascript error.

    Microsoft JScript runtime error: 'this._windows.length' is null or not an object
    Microsoft JScript runtime error: Object doesn't support this property or method

    Any hint would really be appreciated.

    Thank you.

    Hi Abdulla,

    Try the following code snippet and see whether it is working fine.

    CS:
     
    protected void Button1_Click(object sender, EventArgs e)  
    {  
        RadScriptManager.RegisterStartupScript(this, RadScriptManager1.GetType(), "ALERT", "<script type='text/javascript'> Sys.Application.add_load(function(){radalert('Testing RadWin!', 330, 100);})</script>", false);  
    } 

    Thanks,
    Princy.

    Hello Abdulla,

    This error occurred in previous versions of the control when the RadWindowManager was Ajaxified in some way. Please either upgrade to a recent version of the control (the current one is Q1 2009 SP1) or exclude the RadWindowManager from ajaxification.

    If you still experience problems, it will be best to open a support ticket and send us a small sample project so we could examine your exact setup and logic.

    Hello,

    I have exactly the same issue and I am using 2009.1.402 version.  Could you please tell me where I can find SPI?  It is not in my account's download page.

    thanks,

    Jerry

    I'm facing the same problem.  I decide to use Sys.Application.add_load which solves the javascript error pointed in this post.  This solution causes another problem:  every time the user causes a postback on the page, Sys.Application.add_load event stacks the generated messages so the user receives how many messages as how many times he causes postbacks on the page.

    Hello Wveimar,

    You could use the following approach in your solution:
    function f()  
    {  
        //code 
        Sys.Application.remove_load(f);  
    }  
    Sys.Application.add_load(f);  

    More information on the subject is also available in the following blog post:

    Thanks Georgi, with your post i solve the problem.  Although there's a workaround solution to the same issue, which consists in add two RadWindowManager, one of them ajaxified (inside a RadAjaxPanel), and the other in the top of the page (outside the RadAjaxPanel).  Obviously, your solution is better.
