Hi, my data looks like the following

    
                SELECT year(scheduledIn) [theYear] 
        
                , month(scheduledIn)[theMonth] 
        
                , scheduledIn 
        
                ,workOrderId 
        
                FROM            [Work Orders] 
        
                WHERE       aircraftID = 122 
        
                    AND         archived = 0 
        
                    AND completed = 1 
        
                ORDER BY    year(scheduledIn) DESC, month(scheduledIn) DESC

2008   11   2008-11-20 05:21:55.183   4949
2008   7   2008-07-09 11:53:59.307   4124
2008   7   2008-07-14 23:47:14.160   4150
2007   11   2007-11-07 00:00:00.000   2823
2007   8   2007-08-08 12:53:24.167   2304

What I need to do in the TreeView is to display it like this,,,

2008
-->-->11
-->-->-->4949
-->-->7
-->-->-->4124
-->-->-->4150
2007
-->-->11
-->-->-->2823
-->-->8
-->-->-->2304

How can I accomplish this? I need to use this form through my site for various things, so any help would be appreciated. Thanks!

Dropdown not rendering in RadSplitter with RadFormDecorator in IE 7

Hi,

In the following code, the dropdown control does not render in IE 7 or IE 8 compatibility mode. Removing the form decorator control causes the dropdown to render.

I'm running .NET 2.0 and RAD Controls 2009.1.527.20.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="FormDecoratorTest.aspx.cs" Inherits="FormDecoratorTest" %>

skins issue

I'm on my way to update my telerik contol set, and I encounterd a problem with Scheduler. I can not find any docimentation on changes, but direct statements - like here - that css style names are not changed! In fact when changing the control the old skin stops working in a very unplesant way...
There is any info on it?

[Solved] Empty RadMenu gives an JavaScript error "childNodes is null or not an object"

Hi,

After I update my trial version of the RadControls ASP.NET to the full version I started getting a JavaScript error ('childNodes' is null or not an object). Then I realized that it does not allow adding a RadMenu with no items. I'm adding an empty one to be actually created on the server-side.

I'm using the latest version of the RadControls ASPNET AJAX Q1 2009 (2009.1.402.35)

Here is the code which I could replicate the error:

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="TelerikTests2.WebForm1" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml" > 
        
            <head runat="server"> 
        
                <title></title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                <telerik:RadScriptManager ID="RadScriptManager1" runat="server"> 
        
                </telerik:RadScriptManager> 
        
                <div> 
        
                    <telerik:RadMenu ID="RadMenu1" runat="server"> 
        
                    </telerik:RadMenu> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

Isn't it possible to place an empty RadMenu on a page? Or am I doing something wrong?

Thanks,

Eduardo

Ajax, master and controls loaded dynamically

Hello,

Here is my trouble :

I've got a master page (called PODMaster.master) which contains RadAjaxManagerProxy and a contentplaceholder as described below :

    
                    <form id="Form1" method="post" runat="server">  
        
                    <asp:ScriptManager ID="ScriptManager1" runat="server">  
        
                    </asp:ScriptManager> 
        
                    <telerik:RadAjaxManager ID="AjaxManager1" runat="server" EnableAJAX=true>  
        
                    </telerik:RadAjaxManager> 
        
                    <telerik:RadWindowManager Behavior=None ReloadOnShow=true Modal=true InitialBehavior=None VisibleStatusbar=false VisibleTitlebar=false id="Singleton" Skin="Default" runat="server">  
        
                    </telerik:RadWindowManager> 
        
                    <div> 
        
                        <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">  
        
                        </asp:ContentPlaceHolder> 
        
                    </div> 
        
                </form>

Then, the application loads an ascx control (called wucPOD.ascx) which contains different html tables and a contentplaceholder :

    
            <asp:PlaceHolder ID="ContenuPage" Runat="server"></asp:PlaceHolder>

This ascx controls loads dynamically user controls called modules.
A module is an ascx control which contains a label, a placeholder for actions buttons, and a content placeholder.

For example, imagine that I've 2 controls loaded by wucPOD.ascx in my page : controlA and controlB.
The controlA contains a RadGrid 'GrilleRetards' and the RadGrid contains action button.
The controlB contains a RadGrid 'GrillePrets'.

So what I'd like to do is when I click on the button in the RadGrid of the controlA, the RadGrid in the controlB is updated, and the 2 controls are ajaxified, of course.

What could be the best approch to perform this ?

Note that I've already done that with a RadAjaxManagerProxy on controlA and controlB.
In the controlA, on load, i've added AjaxSetting like this :

    
                    If Not IsNothing(SessionsProfil.getModule_Pret()) Then 
        
                        AjaxManagerProxyRetards.AjaxSettings.AddAjaxSetting(GrilleRetards, SessionsProfil.getModule_Pret())  
        
                    End If

and on the command evenement :

    
                                If Not IsNothing(SessionsProfil.getModule_Pret()) Then 
        
                                    SessionsProfil.getModule_Pret().Refresh()  
        
                                End If

But as you see, i saved the module controlB in a session variable to allow refreshing it.
And I think it's not the best approach.

I supose that I need a RadAlaxManagerProxy on the main user control wucPOD, and register each ajaxsetting in child modules (for example controlA) but I'm not sure.
And more, some modules are not ajaxified and need redirections.
So could you please tell me how I could do that ?
Thanks for your answer
Yann

RadWindow Close From Inside RadWindow

I've looked all over the forums and even tryed googling for the solution with no luck. I have 2 sites, one is the parent site that the user will be viewing and another host all the forms, we'll call it the child site, that hosts forms needed to submit info back (parent site is legacy and child are new). The parent site has an older version of 2008.3.1314.35 of telerick ajax controls. The child site has version 2009.01.0527.35. I won't be able to update the parent site because it's a big site and when I tried to update it, I had over 100+ pages that errored out and with one developer it's going to take a while to resolve all the errors.

Now my question is, is it possible for me to open a radwindow with the child site in it from the parent site and close the radwindow and refresh the parent site from a button on the child?

An off question but has to do with the parent site/ child site relationship. How do I maximize the radwindow server side (this is using the radwindow from version 2008.3.1314.35) using follwing code?

    
            RadWindow newwindow = new RadWindow();  
        
            newwindow.ID = "RadWindow2";  
        
            newwindow.NavigateUrl = url;  
        
            newwindow.VisibleOnPageLoad = true;  
        
            newwindow.ReloadOnShow = true;  
        
            newwindow.OffsetElementID = button.ClientID;  
        
            newwindow.Left = new Unit(100);  
        
            newwindow.Top = new Unit(100);  
        
            newwindow.Width = width;  
        
            newwindow.Height = height;  
        
            newwindow.Modal = true;  
        
            newwindow.Behaviors = WindowBehaviors.Default;  
        
            newwindow.KeepInScreenBounds = true;  
        
            RadWindowManager1.Windows.Add(newwindow);

MyBusinessObjects.cs class

In the online help docs i read this...

"If you would like to familiarize with the MyBusinessObjectCollection class and its Select method, it is located under the App_Code/Grid/MyBusinessObjects.cs class of the RadControls for ASP.NET AJAX installation"

Where can i find the complete download for the source files for the MyBusinessObjectCollection since can't locate App_Code with my install?

Kind regards

Displaying multiple items in CB Text

Hi All,

I'm trying to implement a combobox with checkboxes using examples found in other threads. I have the basic functionality working except I can't get the list of selected items to appear in the text area which always shows the text for the first item in the list on page load. Once I get this working I need to extend it to work with multiple combos on the page. Anyway the code is below.

    
                public class ComboCheckBoxTemplate : ITemplate 
        
                { 
        
                    public void InstantiateIn( Control container ) 
        
                    { 
        
                        CheckBox cb = new CheckBox(); 
        
                        cb.ID = "ComboCheckBox"; 
        
                        cb.DataBinding += new EventHandler( CheckBox_DataBinding ); 
        
                        container.Controls.Add( cb ); 
        
                    } 
        
                    void CheckBox_DataBinding( object sender, EventArgs e ) 
        
                    { 
        
                        CheckBox target = (CheckBox) sender; 
        
                        RadComboBoxItem item = (RadComboBoxItem) target.BindingContainer; 
        
                        target.Text = (string) DataBinder.Eval( item, "Text" ); 
        
                    } 
        
                }

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

                </form>

The text in the combo is always "Item 1". At one point it was at least updating the text while the combo was open but that no longer works. Also the button to set values sets the checkboxes but the item text disappears. It reappears if the get values button is clicked.

Any help would be appreciated.
