Refreshing a control on parent after window close.

[Jure]

Hey!
I am using RadWindow to post some comments.
On the main page I have a listview with items, every item has a button named comment, when you click the comment button a new radWindow pops up with a text box and submit button. When you click the submit button the comment is posted and the comment radWindow is closed. Now I need to refresh the listview on parent page with listView.DataBind() command... But I am having some problems in doing that.

Sincerely, Jure

Hi Jure,


Attach OnClientClose to RadWindow and in the handler, invoke an ajaxRequest to server. Now in the server code (AjaxMAnager_AjaxRequest) refresh the ListeVew control.

Feel free to write again if you need further help,


Thanks,
Princy.

Heyas;

How would this work using the Ajax Manager proxy?  For example, I have a master page.  In the content page I have the proxy control, a window manager, 3 windows, and a data grid.  Selecting a record in the data grid provides a form to fill out.  Clicking the "submit" button should submit the form, and close the window.  When the window closes, the grid should rebind.  I've tried setting it up similarly to what some of the other posts suggest, but I am having no success. I am hoping to get help.  Here's the relevant code:

ASPX Code:

<!-- Begin AJAX Code -->
<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadTabStrip1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadMultiPage1" UpdatePanelHeight="" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="CreditsGrid">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadWindowManager1"
                    UpdatePanelHeight="" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>
<!-- End AJAX -->

<!-- Windows Begin -->
<telerik:RadWindowManager ID="RadWindowManager1" runat="server">
    <Windows>
        <telerik:RadWindow runat="server"
            ID="CreditsWindow"
            VisibleOnPageLoad="false"
            OnClientClose="closeRadWindow"
            NavigateUrl="CreditsWindow.aspx"
            Title="Credit transaction review"
            Width="600" Height="550" />

        <telerik:RadWindow runat="server"
            ID="CLTRWindow"
            VisibleOnPageLoad="false"
            Title="Help - Datagrid"
            Width="600" Height="450"
            NavigateUrl="" />

        <telerik:RadWindow runat="server"
            ID="NCRWindow"
            VisibleOnPageLoad="false"
            Title="Help - Datagrid"
            Width="600" Height="450"
            NavigateUrl="" />
    </Windows>
</telerik:RadWindowManager>
<!-- Windows End -->

<!-- Javascript begins -->
<script type="text/javascript">
    function openRadWin()
    {
        radopen(null, "GridHelpWindow");
    }
    function closeRadWindow()
    {
        $find("<%= RadAjaxManagerProxy1.ClientID %>").ajaxRequest();
    }
</script>
<!-- Javascript ends -->

If possible, I would like to simply call the following function in the code behind from the OnClientClose event:

Sub Refresh()

    ProcessReview()
    CreditsGrid.DataBind()

End Sub

Hi beemer,

To make an Ajax request, you need to get a reference to the Ajax manager in the main page, not the proxy. Please check this help article for more details:

Hello Steve,

Give a try with the following approach in the demo.
Window / Edit Dialog for RadGrid

Hope it helps.

Thanks,

The example you reference has the AjaxManager on the same page.  I and the others asking the question have the Ajax Manager on a Master Page.  The <Script> does not recognize the AjaxManager, it does not compile.
How do you refrsh a RadGrid when you have an AjaxManagerProxy on the page and an AjaxManager on a Master page?

[Georgi Tunev]

Hello Terry,

 You can get a reference to the proxy by using the syntax shown in article linked in the reply from 18 Nov. 2010. For convenience I am pasting part of the code below:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript">
    function myUserControlClickHandler() {
        $find("<%= RadAjaxManager.GetCurrent(PageClientID %>").ajaxRequest("content");
    }
</script>
</telerik:RadCodeBlock>

I have an Ajax Manager on a Master Page.  I am having trouble refreshing a RadGrid when I have an AjaxManagerProxy on the page and an AjaxManager on a MasterPage.
I also have RadDatePicker controls on the page.  When I first load the page, one datepicker displays the start of the week and the other datepicker control displays the end of the week.
If I open the RadWindow, make changes and close the RadWindow, the grid refreshs fine.
If I choose start and end dates one month (or any time frame i nthe future) in the future, open the RadWindow and make changes.  When I close the RadWindow, the page assumes it is not a Post Back and reloads the page, resetting the start and end dates to the current week.
I need the grid to refresh without changing the value in the RadDatePicker.
Is this possible?

[Georgi Tunev]

Hello Terry,

If the datepickers are outside of the grid and only the grid is updated via Ajax request, pickers' values should not be reset. To be able to help further however, I need to get a better view over your exact case. Please open a support ticket and send me a small sample project that isolates the problem so I can investigate further.

Kind regards,
