How to get values programmatically from RadWindow?

[mohsinjk jk]

Hi,

I am working RadWindow control. I want to get values from RadWindow and use these in parent window (web page) using C#.Net (code behind).

I have already saw/read some demo but i am not getting because most them are not based on code behind those examples are using aspx.

for example: http://demos.telerik.com/aspnet-ajax/window/examples/clientsideevents/defaultcs.aspx?product=window

I want these type of code in code behind file like C#.Net.

Please guide me.

Thanks

Hello mohsinjk jk,

RadWindow can display a content page, different from the parent one. In such case, because the parent page and the content are 2 separate pages, the communication between them is done on the client - just like with a standard IFRAME.
Since Q3 2009, RadWindow supports content template. In such scenario, the content is on the main page and you can access it directly from codebehind. See this demo and this help topic for more information on the subject.

can I catch the Radwindow close event. and what is this onclientclose? How i can know radwindow is closed now using code behind code.

Hi,


The OnClientClose is the client event which fires when the window closes. A simple method to check whether the window is closed or not, is by placing HiddenField on page and setting the value from OnClientClose event. Now access the HiddenField value from code behind to check whether window clossed.

I am little bit confuse about its functionality. Could you send me any example code. It would be great. Thanks

Hi,

Try setting a hiddenfield as follows to check whether a Window is open.

Javascript:

<script type="text/javascript">
function OnClientClose()
  {
   document.getElementById("HiddenField1").value = "closed";
  }
function OnClientShow()
  {
    document.getElementById("HiddenField1").value = "shown";
  }
</script>

C#:

string windowStatus = HiddenField4.Value;

Thanks,
Princy.
