Tabstrip / Multipage Inside Custom Control

Hi, I am attempting to use a Tabstrip / Multipage inside a custom control. I have created a simple control to illustrate the problem I am having.

    
            using System;  
        
            using System.Collections.Generic;  
        
            using System.Text;  
        
            using System.Web.UI;  
        
            using System.Web.UI.WebControls;  
        
            using Telerik.Web.UI;  
        
            namespace BT.NIEA.StakeholderControls  
        
            {  
        
                [ToolboxData("<{0}:TestTabStrip runat=server></{0}:TestTabStrip>")]  
        
                public class TestTabStrip : WebControl  
        
                {  
        
                    protected override void OnInit(EventArgs e)  
        
                    {  
        
                        // Create a Panel  
        
                        Panel pnlCreate = new Panel();  
        
                        pnlCreate.Visible = true;

                        RadTab tab1 = new RadTab();

                        rmpCreate.SelectedIndex = 0;  
        
                        // Create a Page View

                        Button myButton1 = new Button();  
        
                        myButton1.Text = "Button 1";  
        
                        pvPage1.Controls.Add(myButton1);  
        
                        // Create a Page View  
        
                        RadPageView pvPage2 = new RadPageView();  
        
                        // Create a Button and add it to the PageView  
        
                        Button myButton2 = new Button();  
        
                        myButton2.Text = "Button 2";  
        
                        pvPage2.Controls.Add(myButton2);  
        
                        // Create a Page View  
        
                        RadPageView pvPage3 = new RadPageView();  
        
                        // Create a Button and add it to the PageView  
        
                        Button myButton3 = new Button();  
        
                        myButton3.Text = "Button 3";  
        
                        pvPage3.Controls.Add(myButton3);  
        
                        // Add the PageViews to Our Multi Page  
        
                        rmpCreate.PageViews.Add(pvPage1);  
        
                        rmpCreate.PageViews.Add(pvPage2);  
        
                        rmpCreate.PageViews.Add(pvPage3);  
        
                        // Add The TabStrip to Our Panel  
        
                        pnlCreate.Controls.Add(ts);  
        
                        // Add the MultiPage to the Panel  
        
                        pnlCreate.Controls.Add(rmpCreate);  
        
                        // Finally add the Panel to the Page  
        
                        this.Controls.Add(pnlCreate);  
        
                    }  
        
                    protected override void Render(HtmlTextWriter writer)  
        
                    {  
        
                        base.Render(writer);  
        
                    }  
        
                }  
        
            }

This gives me a JavaScript error: 'undefined is null or not an object', and the tabstrip will not change multipage.
Could someone advise where I am going wrong please?

RadEditor TextChanged event not firing

Hey All,

I am using the RadEditor control (the most recent version) and have implemented a custom toolbar button with a custom dialog. The controls TextChanged event was working just fine until I implemented the custom toolbar button and dialog. However, since the implementation of those items the TextChanged event quit firing. My situation may be unique because I am using a commercial version of Sitefinity. The editor control is being used in a custom edit mode for a custom control. Does anyone have any suggestions as to why the TextChanged event is not firing?

Thank You.

LINQ to SQL as datasource, etc.

Well, tomorrow the 4th is the last day for the special package price, so I need this answered right away.

I have Q3 ASP.net beta version.

Does this support LINQ to SQL? Are there any known problems with using Linq to SQL in my entire project for all controls?

My application is going to be 100% linq to sql, so is this going to be a problem?

thanks.

Moon.

RadMenu hidden by the box container

Dear all,

I am using a RadMenu at the top right border of some boxes (web parts). In some parts once the mouse is over the menu is displayed properly over the current content. In other parts, instead, it is hidden by the border of the box container as it flows "inside it" instead of being displayed at the top of it.

What is curious is that where it does not work properly in Explorer it does in Firefox and the opposite.

I also tried to set z-index:1 in the .RadMenu class (to force the menu at the top level) but the WebResource.axd file seems to keep an old version of the css file without modifications.
The same result even clearing the browser cache and setting UseEmbeddedScripts= "false"; for the RadMenu control (is there another expression to force the system to take the original file instead of taking them from cache?)

Thanks in advance.

Marcel

RadScheduler problem

I'm binding a radscheduler with a datasource...the problem is that the appointments are not getting displayed in the correct cells (time slots in weekly view and day slots in monthly view)....

I have fromTime,ToTime (time only )and date (date only) fields in the DataSource....

time field's format = hh:mm:ss (12h)
date field's format = dd-mmm-yyyy

Do I have to apply specific formats on the fields?

RadControls for Ajax or Not

I have been a user of Telerik for over 2 years and I noticed recently that everything has moved over to the Ajax suite. I can still download the last version of the normal ASP.NET controls, but I wonder, should I be using the Ajax controls because that is where the product suite is going? Can I have both the Ajax and Non-Ajax controls installed on the same machine? Would it hose me? I guess I am asking because right now, I have a mix of Ajax and non-Ajax control needs. In one scenario, just showing some tabs and displaying some data, I really don't want to use Ajax. But I seem forced to in the Ajax controls.

So my question is, can I have both Ajax and nonAjax version of RAD Controls installed? Do I need to? And if I do not...how can I turn off Ajax support from my Ajax version of the suite?
