  Hello,
  
  To explain my problem I'll give you a quite simple example.
  
  I've a RadTreeView, RadWindow and a button on a website.
  After a button click the RadWindow will open. (I use OpenerElementId)
  In the RadWindow a site is loaded with two textboxes and a button.
  
  After a user has entered some text in these two textboxes, the user will click the botton. Now the RadWindow should close and fire an event or postback or callback or somthing, which I can catch on server side.
  
  If I use the JavaScript method radclose(returnvalue), so only one paramter will get back. But I need two values. And how can I get this values on server-site? I know there is an event ClientCallbackFunction but this function allows me only to get one value on client side...but I need these values on server-side!!
  
  Unfortunately, has the RadWindow controll no such events. Only some unusable like init, dispose, unload, databind, ...
  
  I hope you will understand what I mean. I'm not a native English speaker and it's hard to write in a understandable way...
  
  Best regards
  Danny Meier

  Hello dannyyy,
  
  As noted in the documentation (Client-side API section), if you want to return multiple values from the dialog, you will need to create the argument as a new object and assign multiple values to it:

  var arg = new Object(); arg.NameValue = document.getElementById("NewNameArea").value; arg.ProfessionValue = document.getElementById("NewProfessionArea").value;

  A working example of this approach is available in the following Code Library article: Returning multiple Values From a Dialog

  As for sending the results on the server, since the dialogs (just as the standard browser's popup) are created and handled on the client,  you will need to postback / ajax callback the arguments to the server somehow. For example you can use __doPostBack() or document.form1.submit() depending on your scenario. You can do that when the RadWindow is closed, e.g. in the OnClientClose event.

  Hi Kavya ,
  
  I believe that the sample projects from the following forum posts can get you started in your implementation:

  Hello Kavya ,
  
  I went through your code and noticed that you perform loop through all grid items inside the ItemDataBound handler. What is the purpose of this cycle? I have not found any usage of the item variable inside the loop.
  
  Moreover, note that not all grid items will be available on ItemDataBound as some of the rows will not yet be bound to data there. Nevertheless the ItemDataBound event should be raised for each grid row on the current page.
  
  Review once again the sample project from the first linked forum thread in my previous reply to familiarize with the code logic in it and inject it in your project configuration.

  Hello Steve,
  
  The post is quite old (4 years now) and this code library does not exist anymore. You can check our Returning values from a dialog demo that uses the same logic that was shown in the CL.
