Refresh Radgid on Radwindow close without postback

[Kaushal]

Hi ALL,

         Let me tell you my current flow and what i want to do.

         I have one parent page with link as "Add New" and RadGrid, when user click on link radwindow will get open.

        User will fill up the details and click on save button, record will get save into DB and want to refresh the RadGrid on parent page.

        I have used RadAjaxManager on parent page to call radajaxrequest to refresh the grid.and update that particular grid only,

        But on same page i have to maintain history.back functionality on cancel button, whenever ajaxrequest get fire page will get postback.so when user click on cancel button user will stay on same page rather than previous page.

       Can you please help me out to refresh the parent page grid without any postback, so i can mange window.history on cancel button.

Thanks Shinu for your quick reply.

I had gone through your provided reference link and read the discussion.

I had used same approch to refresh my parent page grid on child window close.

Please check my code below.

// Parent page JS.
<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
        <script type="text/javascript">
                 function refreshGrid(arg)
                 {
                // Fire ajax request according to argument.
    if(arg != '')
    {
             $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest(arg);
    }
                 }
                    </script>
    </telerik:RadCodeBlock>

// Parent page html

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest"
        ClientEvents-OnRequestStart="RequestStart" ClientEvents-OnResponseEnd="ResponseEnd">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="radgrd" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="radgrd">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="radgrd"  />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

// Child Page JS

function GetRadWindow() {
    var oWindow = null;
    if (window.radWindow) oWindow = window.radWindow;
    else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
    return oWindow;
}
function CloseWindowWithArgs(args) {
    var oWin = GetRadWindow();
    oWin.close();
    oWin.BrowserWindow.refreshGrid(args);
}

// Parent page ajaxrequest

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
        {
            // Ajax request
            if (e.Argument == Constants.STATUS)
            {
                 radgrd.Rebind();
            }

        }

But whenever ajaxrequest call, page get postback and i can't manage window.history.go(-1).

So, is there any way to refresh grid without page get postback? so i can manage pare history.

Hi Kaushal,

Can you confirm that RadAjaxManager does not come as null in your client method? From what I understand, it is on a parent page of the one that you use to access it, so simply using its client ID will not work. If so, you should try the GetCurrent() method:

$find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest(arg);

All the best,
