OnClose of Radwindow need to perform server side code

[Albert]

Hi,

Is there a way to perform a server side code, say bind a radtreeview after closing the radwindow or is there a way to bind a radtreeview to a linqdatasource control using javascript?

Thanks!

Hello Albert,

You can attach OnClientClose event to the window and make an ajaxRequest like given below and from there you can call the desired function.

ClentSide:

function OnClientClose ()
{
  var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");
        ajaxManager.ajaxRequest();
}

C#:

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
   {
       //your code here
   }

Thanks,
Shinu.

Hi Spiros,

Please have a look into the sample code snippet to achieve your scenario.

C#:

RadWindowManager1.RadConfirm("Are you sure you want to exit?", "CallBackFunction", 500, 300, null, "Confirm");

JavaScript:

function CallBackFunction(args) {
    //args will return the response
}

Thanks,
Shinu.

Thanks for your quick response. My problem is far more complex basically.
From JS
    <telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
        <script type="text/javascript" language="javascript">

            function openWin() {
                var oWnd = radopen("RadProducts.aspx", "RadWindow1");
            }

            function clientShow(sender, eventArgs) {
                var txtInput = document.getElementById("txtInput");
                sender.argument = txtInput.value;
            }

            function clientClose(sender, args) {
                if (args.get_argument() != null) {
                    var txtInput = document.getElementById("txtInput");
                    txtInput.value = args.get_argument();
                }
            }

            function OnClientClose(sender, args) {
                var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");
            alert(args);
            ajaxManager.ajaxRequest(args);
        }

        </script>

    </telerik:RadScriptBlock>

I can pass a textbox as a parameter but on the other form (Popup) i can not get from the
server the value sended

    <script type="text/javascript" language="javascript">

        function GetRadWindow() {
            var oWindow = null;
            if (window.radWindow)
                oWindow = window.radWindow;
            else if (window.frameElement.radWindow)
                oWindow = window.frameElement.radWindow;
            return oWindow;
        }

        function pageLoad() {

            txtInput = document.getElementById('txtUserInput');
            txtSecond = document.getElementById('TextBox1');

            var currentWindow = GetRadWindow();
            txtInput.value = currentWindow.argument;
        }

        function returnArg() {

            var oWnd = GetRadWindow();
            oWnd.close(txtSecond.value);
        }

        function cancelAndClose() {
            var oWindow = GetRadWindow();
            oWindow.close(null);
        }

    </script>
        </telerik:RadScriptBlock>

Any idea .
Thanks

Hi Spiros,

Please have a look into the sample code snippet to pass value from parent page to Radwindow and from RadWindow to parent page.

Parent Page ASPX:

<telerik:RadTextBox ID="radtxtInput" runat="server" Label="Input">
</telerik:RadTextBox>
<br />
<telerik:RadTextBox ID="radtxtOutput" runat="server" Label="Output">
</telerik:RadTextBox>
<br />
<telerik:RadButton ID="radbtnOpenWin" runat="server" AutoPostBack="false" OnClientClicked="ShowDialoag" Text="Show Dialog">
</telerik:RadButton>
<telerik:RadWindowManager ID="RadWindowManager1" runat="server" OnClientClose="OnClientClose">
</telerik:RadWindowManager>

Parent Page JavaScript:

<script type="text/javascript">
    function ShowDialoag(sender, args) {
        var textbox = $find("<%=radtxtInput.ClientID%>");
        radopen("ShowDialog.aspx?TextBoxValue=" + textbox.get_value(), null);
    }
    function OnClientClose(oWnd, args) {
        var arg = args.get_argument();
        if (arg) {
            var txtValue = arg.txtValue;
            $find("<%=radtxtOutput.ClientID%>").set_value(txtValue);
        }
    }
</script>

RadWindow Page ASPX:

<telerik:RadTextBox ID="radtxtAccept" runat="server">
</telerik:RadTextBox>
<telerik:RadButton ID="radbtnClosewin" runat="server" Text="Close with argument"
    AutoPostBack="false" OnClientClicked="returnToParent">
</telerik:RadButton>

RadWindow Page C#:

protected void Page_Load(object sender, EventArgs e)
{
    radtxtAccept.Text = Request.QueryString["TextBoxValue"];
}

RadWindow Page JavaScript:

function returnToParent() {
    var oArg = new Object();
    oArg.txtValue = $find("<%=radtxtAccept.ClientID %>").get_value();
    var oWnd = GetRadWindow();
    if (oArg.txtValue) {
        oWnd.close(oArg);
    }
}
function GetRadWindow() {
    var oWindow = null;
    if (window.radWindow) oWindow = window.radWindow;
    else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
    return oWindow;
}

Hope this will helps you.
Thanks,
Shinu.
