How to close RadWindow after save?

[Wai Loon Ho]

Hi All,

I have a link to popup a RadWindow.
This is working fine.

On the popup window, I have 3 radio button (Excel, PDF, CSV) and 2 buttons (Save As, Close).
This is working fine.

When user click on 'Save As' button, system will show a 'Save As' window to user to choose the file name and file location.
System will then export the data to the format they choose.
This is working fine.

When user click on 'Close' button, system will close the popup window.
This is working fine too.

Now, the problem is the popup window didn't close after the data is exported.
I think this is due to the system still need to continue to do the export even I have the close at the end of the function.

Please help.

Hello,


Consider the RegisterStartupScript() server method to invoke the client function than injecting the script and see whether it helps. I believe that this blog post will be of help.

Hi Shinu,
Thanks for the reply.
Actually I tried this method also. It gave me the same result. The RadWindow popup still failed to close by itself.
User still need to click on the 'Close' button to close the popup.

protected void btnSaveAs_Click(object sender, EventArgs e)
{
    Logger.LogInformation("Start", "btnSaveAs_Click", "DownloadFormat");
        DownloadData();
        if (!Page.ClientScript.IsStartupScriptRegistered("CloseWindow"))
        {
            Page.ClientScript.RegisterStartupScript(this.GetType(), "CloseWindow", "Close();", true);
        }
    Logger.LogInformation("End", "btnSaveAs_Click", "DownloadFormat");
}

I have had similar issues when using the RadWindow and attempting to use the RegisterStartupScript() process to close the RadWindow after the processing within the RadWindow is complete.  Googling the Internet produces many recommendations to use the same RegisterStartupScript -- which I have never been able to get to work correctly.

As a workaround, I have since resorted to (from the code behind portion of the RadWindow) performing a Response.Redirect to a "special" .aspx I create for each of these situations...this "special page" contains very little code:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="UserIsLoggedOn.aspx.vb" Inherits="UserIsLoggedOn" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body onload="returnToParent();">
    <form id="form1" runat="server">
    <div>

    </div>
    </form>
</body>
    <script type="text/javascript">
        function returnToParent() {
            //create the argument that will be returned to the parent page
            var oArg = new Object();
            oArg.selSSO = "Y";
            //get a reference to the current RadWindow
            var oWnd = GetRadWindow();
            //Close the RadWindow and send the argument to the parent page
            oWnd.close(oArg);
        }
        function GetRadWindow() {
            var oWindow = null;
            if (window.radWindow) oWindow = window.radWindow;
            else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
            return oWindow;
        }
    </script>
</html>

Please note that there is no "code behind" for the "special page".  If needed, one could also pass data field values to the "special page" via the query string and use them as arguments when returning to the parent.  This method has resolved my issues.  It's not pretty, but it does seem to work predictably for me.

If you should discover any "secrets" to making the "RegisterStartupScript()" process work correctly, I would love to know them!

Hello Wai,

I noticed that you have your entire page enclosed in the script tag. Why not try moving your table outside of the script tag and see if that helps.

Also, for Lynn, instead of using RegisterStartupScript, why not just use RegisterClientScriptBlock. It's always worked for me using RegisterClientScriptBlock.

I hope that helps.

Wai,

Did you ever find a viable solution for this issue.  I'm having the same issue.

thanks

Hi Justin,

 Basically, what you should do is to execute closing script from the server. If you have tried this but it still does not work, please prepare a sample, fully runnable code (use a fake programmatic datasource of needed) and share the full source code here. Once you provide this, we will built up a test demo and debug and fix it on our side so that you will be then able to apply the same logic in your original application.

Kind regards,
Svetlina

Here is a simple sample.  This sample uses a radwindow to select export options and used RadGrid for exporting.  Once the grid is exported the window should then be closed.  I cannot get it to close.

Hello Justin,

 Thank you for the provided code, we were able to reproduce the problem. We researched it and found that the problem is that the response stream is changed to the file and to achieve what you need with this code you should refresh the page.

However, what we suggest is to first close the radWindow (you should do so anyways) and then invoke the export as shown below:

            var oWindow = null;
            if (window.radWindow) oWindow = window.radWindow;
            else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
            return oWindow;
        }
        function CloseDialog() {
            GetRadWindow().close();

I hope that my reply is helpful and for your convenience I attached a sample demo - let me know how it goes.

Hello Svetlina,

I have the same exact situation and by using your workaround closing the radwindow before doing a postback does nothing but to close the radwindow. It doesnt invoke the export which is defeating the whole purpose. Please let me know if you have any updates or any other workarounds for this situation.

Thanks,
Chad

[Justin]

Chad,

I never found a viable solution to this problem.  I ended up having to leav the window open and requiring the user to close it.

Sorry, I hope you find somwthing that works for ya.

[Marin Bratanov]

Hi guys,

I tried the code provided by Svetlina and I can confirm that it works fine and the RadWindow closes itself. You can find a video from my experiment in the following link: http://screencast.com/t/iMvT5JArfEH. There is only one small omission there - the cancel button calls the same function as the export button, yet this is not related to the other functionality. Please make sure that in your projects the buttons are not wrapped in update panels and the postbacks are executed. If, for some reason the event validation breaks the __doPostBack() function you may try to trigger it by using the client-side name of the button (although this actually does the same as the server code block):

function CloseDialog(button) {
     GetRadWindow().close();
     __doPostBack(button.name, "");
}

<asp:Button runat="server" ID="btnExport" Text="Export" OnClientClick="CloseDialog(this);return false;" OnClick="btnExport_Click" />

Dear Telerik,

How about if you use Radbutton instead of button, why won't it work?

function CloseDialog(button) {
     GetRadWindow().close();
     __doPostBack(button.name, "");
}

<asp:Button runat="server" ID="btnExport" Text="Export" OnClientClick="CloseDialog(this);return false;" OnClick="btnExport_Click" />

Thank you in advanced

[Princy]

Hi Vikas,

Try the following code snippet.

ASPX:

<telerik:RadButton runat="server" ID="btnExport" Text="Export" OnClientClicked="CloseDialog" OnClick="btnExport_Click" />

JS:

function CloseDialog(sender,args)
       {
            GetRadWindow().close();
            __doPostBack(sender.name, "");
       }

Thanks,
Princy.

[vikas]

Dear Princy,

Thank's for the reply how to do it in the back code instead, still using Radbutton .

Regards

[Princy]

Hi Vikas,

I suppose you want to close the Window from server side. You need to inject the javascript function to the asp label as it's text and write the client side method to close the RadWindow as shown below.

ASPX:

<telerik:RadButton runat="server" ID="btnExport" Text="Export"  OnClick="btnExport_Click" />
<asp:Label ID="Label1" runat="server"></asp:Label>

C#:

protected void btnExport_Click(object sender, EventArgs e)
   {
        Label1.Text = "<script type='text/javascript'>CloseDialog()</" + "script>";
   }

JS:

<script type="text/javascript">
    function CloseDialog()
       {
            GetRadWindow().close();
            __doPostBack("<%=btnExport.UniqueID %>", "");
       }
</script>

Hope this helps.

Thanks,
Princy.

I have the same problem . But the difference is that button to download is in Parent Page. then open radwindow and download File.
How I make force the Post-back to close radwindow ?

Thanks

Regards

[Marin Bratanov]

Hello Christian,

If a postback returns as a file it changes the entire response and you cannot register a script that will close the RadWindow.

If you are showing a RadWindow just to download the file and it stays opened without content after that I can suggest you look into the content-disposition HTTP header for your file and send it to the user from the main page without a RadWindow at all. When set to attachment the page will not be disposed because only a file will be returned that will not be inline in the page.

Hi Marin,

Can you please provide some more details for this?

I need to download a document (display save as option) when user clicks on "Ok" button in a rad window and close the window.

Thanks,

Amruta.

[Ahmed]

Simple way to force closing rad window, just put it inside update panel like that :

<asp:UpdatePanel ID="uppChangeHallPriceWindow" runat="server" UpdateMode="Conditional" RenderMode="Block">
  <ContentTemplate>
     <telerik:RadWindow ID="RadWindow1" runat="server">
       <ContentTemplate>
                                       
       </ContentTemplate>
    </telerik:RadWindow>
  </ContentTemplate>
</asp:UpdatePanel>

Important: you have to apply this properties to the update panel :

 UpdateMode="Conditional" RenderMode="Block"

 

then inside the button you want to execute the close command perform :

updatepanel1.update()

this command will close radwindow and no refresh to your Webpage and no need to javascript, I tried it.

[Marin Bratanov]

Hi Ahmed,

I would generally advise against such an approach. Please review the following articles on the matter:

• using RadWindow with AJAX and why you should avoid such an update panel, unless absolutely necessary (and why it has the effect of closing the RadWindow): http://docs.telerik.com/devtools/aspnet-ajax/controls/window/how-to/how-to-use-radwindow-with-ajax.
• how to open a RadWIndow from the server code (and, thus, how to close it - just replace the call to show() with close()): http://docs.telerik.com/devtools/aspnet-ajax/controls/window/troubleshooting/opening-from-the-server.
