Can a server-side RadWindow's content survive a postback?

I couldn't find a direct answer to this question, and I haven't had any luck making it work either.

For example:
on "Page0.aspx", I have a RadWindowManager and a button.
When I click the button, a RadWindow is created and added to the RadWindowManager server-side.

Initially, the RadWindow loads "Page1.aspx"....from "Page1", I navigate to "Page2.aspx" (This is all inside the RadWindow)

Now, I click the button on "Page0.aspx" and it adds another RadWindow to the RadWindowManager.

My first RadWindow which should be showing "Page2", now goes back to its default page: "Page1".

I've messed with opening RadWindows client-side and that seems to do what I want to a limited extent.

But I want to be able to work with the RadWindows server side. Possible?

Grid Repaint

I am having some trouble using the repaint method??
The problem I am having is that the filter is a set of textboxes, drop-down, etc. When I hide them the grid moves up and expands to fill the available space, as I would like it to do. But the grid contents just move up and dont expand.

Here is my javascript code (I am able to access the grid, but the repaint method does not seem to exist):

case "tbrQueryPanel":

var filter = contentWin.document.getElementById("filter");

if (filter) {

if (filter.style.display == '') {

filter.style.display = 'none';

}

else {

filter.style.display = '';

}

var grid = contentWin.document.getElementById("Grid_RadGrid");

grid.repaint();

break;

Here is my Grid (scrolling and static headers are enabled, and it is nested inside a user control, which is nested inside a radpane, inside another container):

<telerik:RadScriptManager ID="ScriptManager" runat="server" />

<telerik:RadGrid ID="RadGrid" runat="server" Width="100%" Height="100%"

Font-Names="Verdana" GridLines="Horizontal" AllowSorting="True" ShowGroupPanel="True"

Skin="Office2007" AllowPaging="True" PageSize="50" AutoPostBack="True">

<MasterTableView>

<HeaderStyle Wrap="false" />

</MasterTableView>

<ClientSettings AllowDragToGroup="True">

<Scrolling UseStaticHeaders="true" AllowScroll="True" SaveScrollPosition="True"/>

<Selecting AllowRowSelect="True" />

<ClientEvents OnRowDblClick="RowDblClick" />

</ClientSettings>

<PagerStyle AlwaysVisible="true" />

<ExportSettings ExportOnlyData="true" IgnorePaging="true"/>

</telerik:RadGrid

>

Closing Dock Triggers 'Compatibility Mode', Refreshes Page

Hi, I created a simple Dock to pass messages back but when the close icon in the dock is clicked IE8 triggers compatibility mode and reloads the page. After that I can refresh the page and everything works. It is only on the first page load the issue presents itself.

Here is my code, first the Master Page:

Master page code behind (simplified):

namespace Web.App_Templates

{

using System;

using System.Web.UI;

public partial class Site : MasterPage

{

public void ShowFeedback(string feedBackText, bool useAlert)

{

if (feedBackText == string.Empty)

{

this.Feedback.Text = feedBackText;

this.TelerikDock.Title = feedBackText;

this.TelerikDockLayout.Visible = false;

}

else

{

if (useAlert)

{

var radAlertScript =

string.Format(

"function f(){{radalert('{0}', 330, 210);Sys.Application.remove_load(f);}};Sys.Application.add_load(f);",

feedBackText);

ScriptManager.RegisterStartupScript(

Page,

Page.GetType(),

"Feedback",

radAlertScript,

true);

}

else

{

this.Feedback.Text = feedBackText;

this.TelerikDockLayout.Visible = true;

}

public void ShowFeedback(string feedbackTitle, string feedBackText, bool useAlert)

{

if (feedBackText == string.Empty)

{

this.Feedback.Text = feedBackText;

this.TelerikDock.Title = feedBackText;

this.TelerikDockLayout.Visible = false;

}

else

{

if (useAlert)

{

var radAlertScript =

string.Format(

"function f(){{radalert('{0}', 330, 210, '{1}');Sys.Application.remove_load(f);}};Sys.Application.add_load(f);",

feedBackText,

feedbackTitle);

ScriptManager.RegisterStartupScript(

Page,

Page.GetType(),

"Feedback",

radAlertScript,

true);

}

else

{

this.Feedback.Text = feedBackText;

this.TelerikDock.Title = feedbackTitle;

this.TelerikDockLayout.Visible = true;

}

(bear with me :) Content Page:

<%@ Page Title="Home" Language="C#" MasterPageFile="~/App_Templates/Site.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Web.Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<%@ MasterType VirtualPath="~/App_Templates/Site.Master" %>

<asp:Content ID="HeadContent" ContentPlaceHolderID="HeadContentPlaceHolder" runat="server">

</asp:Content>

<asp:Content ID="ScriptContent" ContentPlaceHolderID="ScriptContentPlaceHolder" runat="server">

</asp:Content>

<asp:Content ID="MainContent" ContentPlaceHolderID="MainContentPlaceHolder" runat="server">

</asp:Content>

...and finally, the content page code behind (again simplified):

namespace Web

{

using System;

public partial class Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

this.Master.ShowFeedback("Test Title", "Test normal feedback message.", false);

// this.Master.ShowFeedback( "Test Title", "Test pop-up feedback message.",true);

}

Everything works fine, there are no errors (client or server) but when I click close, that is when the compatibility view triggers and the page reloads (displaying the messages again).

Can anyone tell me what the issue is? I'll admit my experience of using Dock is minimal, so hopefully it's something stupid simple :)

Thanks in advance,
Richard

RadGrid Export error -- No data exported

RadAjaxPanel.AjaxPanelRequestEventHandler vs RadAjaxControl.AjaxRequestDelegate

Hi,

I am upgrading an application from Classic Telerik controls to the latest ASP.NET AJAX ones. I have replaced the following line of code

AjaxPanel.AjaxRequest -=

new RadAjaxPanel.AjaxPanelRequestEventHandler(ContentPaneControl_AjaxRequest);

with this one:

AjaxPanel.AjaxRequest -=

new RadAjaxControl.AjaxRequestDelegate(ContentPaneControl_AjaxRequest);

because the former would no longer compile.

It's crazy, but I can't even find where I got the idea for the second line. Anyway, the problem is that it works with some of my controls but not with others. For some controls it goes into ContentPaneControl_AjaxRequest, for others - it doesn't. The code is all in one script. They all go to that same script.

Any ideas?

Thanks,
Olga

Create RadAjaxManager in codebehind

Hi,

Is it possible to create RadAjaxManager in codebehind?

I have a master page and I am creating a RadAjaxManager in the OnInit method of the master page. Later when I try to ajaxify a control within an aspx page using the AddAjaxSettings method I created in master page I get Object reference not set to an instance of an object.

Master Page

protected override void OnInit(EventArgs e)

{

HtmlForm form = (HtmlForm)this.Controls[3];

form.Controls.Add(new RadAjaxManager());

}

public void AddAjaxSetting(Control ajaxified, Control updated, RadAjaxLoadingPanel loading)

{

HtmlForm form = (HtmlForm)this.Controls[3];

RadAjaxManager ajax = form.Controls[1] as RadAjaxManager;

ajax.AjaxSettings.AddAjaxSetting(ajaxified, updated, loading);

}

ASPX page

protected void Page_Load(object sender, EventArgs e)

{

(this.Master as PortalMaster).AddAjaxSetting(button, panel, loading);

}

Edit: I get the null reference error in ajax.AjaxSettings.AddAjaxSetting(ajaxified, updated, loading); line. All variables are pointing to correct objects (ajax, button, panel, loading).

Thank you...

Ajax
