In one of these usercontrols I have a grid with a list of data, where it is possible to open a radwindow. In this window user can do some update of data and when user close this window I want to refresh the grid. I have readed all possible information about the AJAX wai to do this, but nothing happent. Can anyone help me?

Here is the code.

user control who hold the grid:

    }
    function ShowEditForm(id, rowIndex, tp) {
        var grid = $find("<%= RadGrid_AKtivitetsListe.ClientID %>");

        var rowControl = grid.get_masterTableView().get_dataItems()[rowIndex].get_element();
        grid.get_masterTableView().selectItem(rowControl, true);

       if (tp == "copy")
       {
           WindowOpen(1000, 600, "../UI/AktDetaljer/AktivitetsCopy.aspx?AktID=" + id, "eMTEP-DK - Aktivitetsdetaljer");

Hi Fan,

In your code you have set the RadAjaxManager proxy to update the grid. For the logic to work however, you need to set the RadAjaxManager control to do that. To do this, you need to programatically set (in Page_Load or Page_Prerender):
RadAjaxManager.GetCurrent(Page).AjaxSettings.AddAjaxSetting(RadAjaxManager.GetCurrent(Page), RadGrid_AKtivitetsListe)

I hope this helps.


Best wishes,

Thank you Georgi and HAPPY NEWYEAR

It don't work. The only way I can get it to work is by activating the client onclose script.

Hello Fan,

I was not able to run your code so at this point I cannot tell what the reason for the problem is. Please isolate the problem in a separate, runnable project (this blog post will help you in this task) and send it to us in a support ticket. There is no need to send us your real database - you can use one of the fake ones linked in the blog.
Once we receive that project, we will check it and get back to you right away.


Regards,
Georgi Tunev
