Question on returning values to a parent window.

[Sam]

Hi,

I am basing my code off of the sample you have here:
http://demos.telerik.com/aspnet-ajax/window/examples/dialogreturnvalue/defaultcs.aspx

In your sample, on the aspx page for "Dialog2.aspx" is a javascript function:

function returnValue()
{
    //get the RadComboBox's selected item's text
    var combo = $find("<%= RadComboBox1.ClientID %>");
    var selectedCapital = combo.get_text();

    //Get a reference to the parent page (Default.aspx)
    var oWnd = GetRadWindow();

    //get a reference to the second RadWindow
    var dialog1 = oWnd.get_windowManager().getWindowByName("RadWindow1");

    // Get a reference to the first RadWindow's content
    var contentWin = dialog1.get_contentFrame().contentWindow

    //Call the predefined function in Dialog1
    contentWin.populateCityName(selectedCapital);

    //Close the second RadWindow
    oWnd.close();
}

This line here, works great, but I need to try to modify:

contentWin.populateCityName(selectedCapital);

instead of calling a function (in this case "populateCityName") I want to be able to set the control's value directly.
Is this possible?
So instead of the above line of code, I would like to do something like:

contentWin.document.getElementById("cityName").value = "hello";

Hello Sam,

In such scenario, the logic stays basically the same. The difference is that you should pass the new value as a parameter and then set it where you need it in the function on the other page.
e.g.
contentWin.populateCityName(someValue);

and in the content page
function populateCityName(arg)
{
   document.getElementById("someElement").value = arg;
}

Thank you for your response!

However, I understand the demo on the site as well as what you posted, but that's not what I'm trying to do.
I'm trying to avoid using a function on the content page.
Instead of:  contentWin.functionName(someValue)

I want to directly use "getElementById" to access controls on the content page without having to use a function to contain the calls to getElementById.

I know it's not elegant to do it this way, but I'm trying to update our existing app and this would be the easiest way to integrate the radwindow with the existing code structure.

Thanks!

Hello again Sam,

I apologize for the misunderstanding.
Yes, this is possible - you need to get a reference to the RadWindow first - in the sample below I used $find(), but if you are using RadWindowManager, you could use GetRadWindowManager().getWindowByName("winName") as well.

function setValueInWindow()
{
    //get a reference to the RadWindow
    var oWnd = $find("<%= RadWindow1.ClientID %>");
    var conentWin = oWnd.get_contentFrame().contentWindow;
    conentWin.document.getElementById("txtInput").value = "hello";
}

Note however, that this would not be applicable for complex scenarios where you have nested controls in the content page (Master / Content page for example). In such case, the ClientID of the control differs than the original one and you will need to hardcode it as you will not be able to use
<%= someControl.ClientID %>
