[Solved] Window Behaviour after AJAX Request

[Marco]

Hello,

I launch the windows from image buttons in a template column in a radgrid (located in a content page that inherits from a masterpage). When I click the cancel buttons on the window and simply close the window, the original settings i specify are maintained. However, when I click a button that does something then executes an ajax request to refresh the underlying grid, every window I open loses the settings I previously defined.

My RadWindowManager/Window setup:

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" Behavior="None"
                InitialBehaviors="Pin" KeepInScreenBounds="True" Modal="True"
                PreserveClientState="True" ReloadOnShow="True" ShowContentDuringLoad="False"
                VisibleStatusbar="False">
                <Windows>
                    <telerik:RadWindow Skin="Vista"  ID="InsertTaskWindow" runat="server"
                        Title="Criar Tarefa" Height="620px"
                        Width="750px" Left="" Modal="true" Overlay="True"
                        ShowContentDuringLoad="False" Behavior="None" Behaviors="None"
                        InitialBehavior="Pin" InitialBehaviors="Pin" ReloadOnShow="True"
                        VisibleStatusbar="False" KeepInScreenBounds="True"  />
                    <telerik:RadWindow Skin="Vista"  ID="EditTaskDialog" runat="server"
                        Title="Editar Tarefa" Height="620px"

                        Behaviors="None" InitialBehavior="Pin" InitialBehaviors="Pin"
                        KeepInScreenBounds="True" Left="" Modal="True" NavigateUrl=""
                        ReloadOnShow="True" ShowContentDuringLoad="False" style="display:none;"

                </Windows>
            </telerik:RadWindowManager>

Example Window JavaScript:

<script type="text/javascript">
            function CloseAndRebind(args) {
                GetRadWindow().Close();
                GetRadWindow().BrowserWindow.refreshGrid(args);
            }

            function GetRadWindow() {
                var oWindow = null;
                if (window.radWindow) oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog
                else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; //IE (and Moz as well)

                return oWindow;
            }

            function CancelEdit() {
                GetRadWindow().Close();
            }


        </script>

Code executed on clicking a cancel button:

protected void LnkCancelChanges_Click(object sender, EventArgs e)
    {
        ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "CancelEdit();", true);
    }

Code executed on clicking "accept" button:

protected void LnkAcceptChanges_Click(object sender, EventArgs e)
    {
        int result = SqlDataSourceEdit.Update();

        ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "CloseAndRebind();", true);
    }

JavaScript refresh grid function on content page:

function refreshGrid(arg) {
                        $find("<%= RadAjaxManager.GetCurrent(this).ClientID %>").ajaxRequest("Rebind");
                    }

Ajax request code on content page:

protected void RadAjaxManagerProxy1_AjaxRequest(object sender, AjaxRequestEventArgs e)
    {
        RadGrid grid = (RadGrid)LoginView1.FindControl("RadMultiPageMain").FindControl("PageViewTarefas").FindControl("RadGridTarefas");
        if (e.Argument == "Rebind")
        {
            grid.MasterTableView.SortExpressions.Clear();
            grid.MasterTableView.GroupByExpressions.Clear();
            grid.Rebind();
        }
        else if (e.Argument == "RebindAndNavigate")
        {
            grid.MasterTableView.SortExpressions.Clear();
            grid.MasterTableView.GroupByExpressions.Clear();
            grid.MasterTableView.CurrentPageIndex = grid.MasterTableView.PageCount - 1;
            grid.Rebind();
        }
    }

Any Ideias?

Thanks in advance.

I've noticed that if I refresh the browser, the window settings I specified are applied again. Could this be an ajaxmanagerproxy issue?

[Marco]

I believe I've found a temporary solution. On the content page (code-behind), where I initiate a rebind of my grid via the ajax request, if I manually respecify all my parameters they will take effect on subsequent window loads. But I'm still in the dark on why the manager and window settings are defaulted/lost. Any ideas?


Thanks in advance.

Hi Marco,

The code that you posted looks fine and at this point we cannot tell what the reason for the problem might be. If you manage to isolate the problem in a small sample project, please send it to us and we will check it.
