Send dynamic content (json client-side, string server-side) to RadWindow
I'd like to send JSON (or string) object to RadWindow to be able to populate its content with  this object.
Similar to Value RadNotification property: public string Value { get; set; }

Code snippet below illustrates what I'd like to achieve.


function showWindow(jsonObject) {
    var windowManager = GetRadWindowManager();
    if (windowManager) {
        var window = windowManager.getWindowByName("RadWindow1");

        if (window != null) {
            window.DynamicContent = jsonObject; //Set content
            window.show();
        }
    }
    return;
}

function RadWindow1_Show(sender, args) {
    var jsonObject = sender.DynamicContent;

    if (jsonObject != null) {
        var selector = null;

        selector = 'span[id*="Content"]';
        var domElements = $telerik.$(selector);
        if (domElements != null && domElements.length > 0) {
            var spanId = domElements.attr('id');
            var span = $get(spanId);
            if (span != null)
                span.innerHTML = message;
        }
    }

    return;
}

Hello Ricard,

The code snippet you have share would actually work, as you can add custom expando properties to the client-side object:

<telerik:RadWindowManager runat="server">
    <Windows>
        <telerik:RadWindow runat="server" OnClientShow="OnClientShow" ID="RadWindow1">
            <ContentTemplate>
                <div class="window-content"></div>
            </ContentTemplate>
        </telerik:RadWindow>
    </Windows>
</telerik:RadWindowManager>
<input type="text" id="fn" value="John" />
<input type="text" id="ln" value="Doe" />
<telerik:RadButton runat="server" OnClientClicked="OnClientClicked" ID="RadButton1" Text="Show Window" AutoPostBack="false" />
<script>
    function OnClientShow(sender, args) {
        var name = sender.DynamicContent.FirstName + " " + sender.DynamicContent.LastName;
        $telerik.$(sender.get_contentElement()).find(".window-content").text(name)
    }
    function OnClientClicked(sender, args) {
        var wnd = GetRadWindowManager().GetWindowById("RadWindow1");
        wnd.DynamicContent = {
            FirstName: document.getElementById("fn").value,
            LastName: document.getElementById("ln").value
        };
        wnd.show();
    }
</script>

 

If you need to pass some data from the server-side, you can add it to the Attributes collection and access it on the client-side.

C#:

 RadWindow1.Attributes.Add("my-data", "Server-side data");

JavaScript:

windowObj.get_element().getAttribute("my-data");

Another way is storing the data in a hidden field, which you can access on the client-side. For more complex data, you can serialize an object to JSON string from the server-side and on the client-side use the JSON.parse(), to receive an object from the string.
