Hello,

I have Explorer.aspx that defines a RadWindowManager as seen below:

<telerik:RadWindowManager ID="radWinMgr" runat="server" AutoSize="true" EnableShadow="true" ReloadOnShow="true" ShowContentDuringLoad="false" VisibleStatusbar="false"  OnClientClose="fncClientClose">
    <Windows>
        <telerik:RadWindow ID="rwUploadParent" runat="server" Behaviors="Close" NavigateUrl="Upload.aspx"></telerik:RadWindow>
        <telerik:RadWindow ID="rwDownloadParent" runat="server" Behaviors="Close" NavigateUrl="Download.aspx"></telerik:RadWindow>
    </Windows>
</telerik:RadWindowManager>

 

The OnClientClose function that you see referenced above is defined as follows:

<script type="text/javascript">
    function fncClientClose(winNewRep, args) {
        var arg = args.get_argument();
 
        if (arg == 1) {
            //Refresh file explorer:
            var oExplorer = $find("<%=radExplorer.ClientID%>");
            var dirPath = oExplorer.get_currentDirectory();
 
            if (dirPath) oAjaxPanel.ajaxRequest(dirPath);
        }
    }
</script>

 

The purpose of the function is to refresh the RadFileExplorer, but this function never gets called. I have a button click the opens Upload.aspx as a RadWindow as follows:

<asp:Button ID="btnUpload" runat="server" Text="Upload" OnClientClick="fncOpenPopupWin('UploadMgr.aspx?UpFolder=', 'rwUploadParent'); return false;" />

 

As you see the OnClientClick of the button calls another function and passes the page name to open, including a query string parameter, and the name of the RadWindow:

<script type="text/javascript">
    function fncOpenPopupWin2(strPage, strParent) {
        var varLocation = "/Root";
        var winNewRep = radopen(strPage + varLocation, strParent);
    }
</script>

 

When the button is clicked, page Upload.aspx opens, the user does what he/she wants, and then closes Upload.aspx. At that point, I expect the OnClientClose of the RadWindownManager to execute, but it never does.

I have read many postings about this kind of problem here on the forum, but none of the solutions have helped my situation. I appreciate any time someone takes to review this and offer suggestions.

 

Thank you,

Steven

Hello Steven,

Have you gone through the following help article: http://www.telerik.com/help/aspnet-ajax/window-troubleshooting-wrong-window-opened.html? If this is not the case - do you have the AjaxControlToolkit in the Bin folder and if so - what happens if  you remove it? Also, have you examined your page for JavaScript errors and does resolving them help, if there are any? What I also notice in your snippets is that the button's click calls fncOpenPopupWin() while you have pasted a function fncOpenPopupWin2(strPage, strParent) so the difference may be coming from a different piece of code there.


All the best,

Marin,

 

Thank you for your response.

 

I had not read the article that you provided, but I have now. It discusses the issues of having more than one RadWindowManager in a page. I had already read about this in other forum postings that discussed the same problem that I am having. I went through the Opening Windows documentation as well.

 

I originally had 2 RadWindowManager in my page, one for each RadWindow, I moved my 2 RadWindow into one RadWindowManager, leaving me with only 1 RadWindowManager.

 

I am not utilizing a master page within my project, so that should rule out any possible issue of another RadWindowManager. When I go to Edit > Find within Visual Studio to search through my ASPX and look for instances of RadWindowManager, I only find one instance. But when I load the same page into my web browser and then right-click > View Source, the source shows 2 instances of RadWindowManager, as follows:

 

Sys.Application.add_init(function() {

    $create(Telerik.Web.UI.RadWindowManager, {"autoSize":true,"clientStateFieldID":"radWinMgr_ClientState","enableShadow":true,"formID":"frmFileExplorer","iconUrl":"","minimizeIconUrl":"","name":"radWinMgr","reloadOnShow":true,"showContentDuringLoad":false,"skin":"Windows7","visibleStatusbar":false,"windowControls":"['rwUploadParent','rwDownloadParent']"}, {"close":fncClientClose}, {"child":"rwUploadParent"}, $get("radWinMgr"));

});

Sys.Application.add_init(function() {

    $create(Telerik.Web.UI.RadWindowManager, {"behaviors":36,"clientStateFieldID":"radFileExplor_windowManager_ClientState","enableAriaSupport":true,"formID":"frmFileExplorer","height":"340px","iconUrl":"","minimizeIconUrl":"","modal":true,"name":"windowManager","shortcuts":"[[\u0027close\u0027,\u0027Esc\u0027]]","skin":"Office2010Blue","title":"Upload","visibleStatusbar":false,"width":"451px","windowControls":"[]"}, null, null, $get("radFileExplor_windowManager"));

});

 

I have no clue as to why it shows a second RadWindowManager for radFileExplor (this is the ID that I assigned to my RadFileExplorer control). Could this be the reason why my OnClientClose is not executing when I close my RadWindow? The first RadWindowManager (radWinMgr) is the only one I see when I am in design view of Visual Studio. If this second RadWindowManager is the cause of my problem, how do I resolve this problem, since I don’t see this second RadWindowManager while in design view of Visual Studio? As I have mentioned, I am not using a master page within the project.

 

Thank you,

Steven

 

BTW, the fncOpenPopupWin2 that I mention in my initial post is basically a typo. Throughout my project, it is simply fncOpenPopupWin.

Hello Steven,

The RadFileExplorer uses a RadWindowManager internally and this is why it is present in the page source. This is why I advised that you examine it so see the order in which they are created. The article I linked also offers the way to solve the case - by using $find(desiredManagerClientID).open() instead of just radopen():
var winNewRep = $find("<%=radWinMgr.ClientID %>").open(strPage + varLocation, strParent);

in fncOpenPopupWin().
