Hi,
My problem is that on my opened RadWindow I have a RadGrid.
Is it possible to return a complex list of object to parent?
Lets say my grid has 3 columns (1 checkbox and 2 string ones)
Can I return something like datasource or create custom class in js?
Should I iterate through the radgrid items?
Any code sample would be great.
Thanks

Hello Margan,
The RadWindow provides methods for communication between the RadWindow and the parent. For this you need to subscribe to the following functions.

Hi Shinu,
I already implemented the communication and I can return simple types like string.
My problem is that I would like to return more complex type.
What I want to do is to return data from RadGrid in that opened RadWindow.
My question is how to get that data from RadGrid in my js ReturnToParent function.
I need to extract that data from RadWindow and on my parent page I have to create a new RadGrid using this extracted data.
Thanks

Hi Sebastian,
You can return any object you create in the RadWindow to the main page when you close it. How you are going to create that object and then interpret its value depends on your custom scenario.
To see how to transfer objects after the window is closed take a look at the following demo: http://demos.telerik.com/aspnet-ajax/window/examples/dialogreturnvalue/defaultcs.aspx and more notably the returnToParent() function in Dialog1.aspx. This object is retrieved in the OnClientClose() event handler in the main page.

Hi,
Yes I used that example earlier.
But I was wondering how i can for example iterate through DataGrid and return to parent a list of strings for example.
Nevertheless now I have this kind of problem.
I've returned simple text from my RadWindow and now I want to add it to a ListBox.
The js sample code looks like this:
But this fails and I get Telerik.Web.UI.RadListBoxItem is not a constructor
Any ideas why?

var custom = arg.custom;

}
}
But this fails and I get Telerik.Web.UI.RadListBoxItem is not a constructor
Any ideas why?

Hello Sebastian,
The Telerik Controls are server controls, which means that you cannot dynamically create them via JavaScript, but only through server-side code (as any other server control).

Thanks Marin,
I was just referring to code from http://demos.telerik.com/aspnet-ajax/listbox/examples/clientside/addremovedisable/defaultcs.aspx
where the function is in javascript like this:
So it can't be done? When I use the RadWindow and return some values from it I can't populate any RadListControl with it? It works only when populating simple textboxes or something like that?
Thanks

listBox.trackChanges();
//Instantiate a new client item

item.set_selected(true);
listBox.get_items().add(item);
item.scrollIntoView();

Hello Sebastian,
On my end this seems to be working fine. You can find my test page attached as a reference. Here is a video from my experiment: http://screencast.com/t/9lXbWKQG3HbG.
If you are still experiencing difficulties modify my page until it displays the unusual behavior and send it back.
All the best,
