Unable to set value of the property 'OnClientClose': object is null or undefined

[Tinoy Malayil]

Hi moderator/admin,

When I click to open the radwindow in Internet Explorer 9 browser I got the following error:
Message: Unable to set value of the property 'OnClientClose': object is null or undefined
Line: 67
Char: 3
Code: 0

My js file is written as follows to open radwindow:

<code>
function openradwindow(windowname,TitleBarBackgroundColor,navigateurl,width,height,titleimage,titlename)
{
    try
    {
    
    var oWindow =window.radopen(navigateurl, windowname);
//    var oContentFrame = oWindow.get_ContentFrame();     
    
    oWindow.SetTitle(titlename);
    var divWin = document.getElementById("RadWindowWrapper_ctl00_radwindow");
    divWin.style.backgroundColor = TitleBarBackgroundColor;
    //divWin.style.zIndex=3049;
    //divWin.style.position=relative;
     divWin.style.titlename=titlename;
    var i;
    
    for(i=0;i<10;i++)
    {
        if(document.styleSheets[i]!=null)
        {
            
            var strStyleSheetName = document.styleSheets[i].href;
            if(strStyleSheetName != null)
            {
            //added for radwindow icon image and background color of icon image
            if( strStyleSheetName.indexOf( "RadControls/Window.RadControls.css" ) != -1 )
            {
                try
                {
                    //document.styleSheets[i].rules[0].style.backgroundImage = "url("+titleimage+")";
                    
                    document.styleSheets[i].rules[0].style.backgroundColor =TitleBarBackgroundColor;
                }
                catch(err)
                {
               
                    //document.styleSheets[i].cssRules[0].style.backgroundImage = "url("+titleimage+")";
                   
                    document.styleSheets[i].cssRules[0].style.backgroundColor = TitleBarBackgroundColor;
                   
                }
            }
            }
        }
    }
    oWindow.SetWidth(width);
    oWindow.SetHeight(height);
    oWindow.show();
  }
  catch(err)
  {
  }  
 
  oWindow.OnClientClose = function()   
  {   
    oWindow.SetUrl("about:blank");
    oWindow.remove_close(OnClientClose);  
  }  
   
 }

The above javascript function is working fine in all other browsers.

Hello Tinoy,

I am not quite sure about the version you are using. I suppose this problem is related to the version you are using.  from Q1 2011 telerik officially support IE9 and if you upgrade to it or a later version, everything will work fine.

You can check this forum thread for more information.

Thanks,
Shinu.

Hi Shinu,
I am using Telerik ASP.Net Ajax Version 2008. The rad window is not opening in IE 9.It works if we add meta tag to set compatibility to IE8.
