There are some errors in the tutorial.  On page 188, the document says to add the CreateUswerWizardWrapper.  The Create User control has not even been created yet.  Not even a blank file.  The details of the create user wizard aren't filled out until page 192.  Yet the document says to hit Ctrl + F5 on page 188.  It will not run if you've already added the control for

Also, I turned the "sign up" button to point to Register.aspx, but this is never mentioned in the document.

Lastly, it's a little ambiguous as to where to add the code on page 183.  Is this code to be added to WebProfile.cs or some other file?  When you added "public class WebProfile" to the class WebProfile, you get "Error  'WebProfile': member names cannot be the same as their enclosing type".  I knew what to do, but not sure everyone will without clarification.

Great tutorial though.  Just some minor stuff.

Alan's a lot farther into the tutorial than I am. 

I'm new to telerik controls, and these tutorials are just what I need.  I've just begun the tutorials, and I've found some errors as well (I'll post more as I go, if you'd like).

minor error p.30: 
menuItem.NavigateUrl = "http://www.telerik.com (http://www.telerik.com/)";  
 

should be:
menuItem.NavigateUrl = "http://www.telerik.com";  

(That's how it is in the source code)

p.31:   

 

Value="<%=MyConstants.PURCHASE_TICKETS%>">  
 

should be:

Value="<%#MyConstants.PURCHASE_TICKETS%>"

(There are three places where "<%=" should be replaced with "<%#").

There also needs to be a "DataBind();"  in Page_Load().  Perhaps that's obvious to some, but it wasn't to me, and I didn't see it mentioned on this page (p.31).   Similarly, it wasn't obvious to me that Constants were in the same namespace as the aspx page (the courseware made a big deal about what namespace the constants were in, so I assumed it was different from the rest), and I spent some time trying to figure out how that was suppose to work.  I was very happy when I found the source code files, as that cleared everything up.

As I said, this is my very first use of telerik controls, so it's likely I'm getting hung up on stuff that other people wouldn't.

Hope this is helpful!

Speaking of the source code to the tutorial:

When I open the samples, I get a variety of "component not found" errors that eventually go away when I add a RadAjaxManager to the file. 

My questions are:
1) Is it suppose to be this way?
and if "yes",
2) Why isn't the RadAjaxManager already in the file when I open it?  Is it a version thing?

Thanks in advance!

The download of the chm helpfiles shows problems on the two systems I have tried it with.

One box uses IE6 (testing machine).  All pages show an error instead of the document.

One box uses IE7 (this box).  All pages report a script error, and after clicking through the error I can view the contents.

Hello Scott,

Is it possible that the issue you encountered with the chm version of the help is due to the reason depicted in this KB article? Please try the solution discussed in the article and let us know whether this addresses the problem.

Kind regards,

No.  There are two solutions in the referenced KB article.  I tried both on both systems and neither fixes my problem. 

I did not recieve an open file security warning, so method 1 is inapplicable.

I had attempted using the the 'Unblock' solution before writing the first time for the IE6 system without success.  After you pointed me to this article I attempted the same thing on the IE7 box with no change in behavior.

Since I was evaluating Telerik and we don't have a contract yet, sending in screenshots with a support ticket is not an option.

For IE6: the help app starts, but then fails to display the pages.   Instead of the contents, it displays an explorer error page that says "The page cannot be displayed" at the top and "Cannot find server or DNS Error Internet Explorer" at the bottom.   So my system acts like it needs to reference some non-existant address but fails when making the attempt.

For IE7: The help app starts, but during the startup it freezes up with a javascript permissions error.
Line: 18  
Char: 5  
Error: Permission Denied  
Code: 0  
URL: mk@MSITStore:C:(long path)\RadControlsForASP.NET.AJAX.chm::/mk:@MSITStore:C:\(error cuts off here due to length)  
 
   Do you want to continue running scripts on this page?  
                        [Yes][No] 

It doesn't matter if you click Yes or No, the page will display after that, minus the nice formatting one gets in the online version.

Hi Scott,

Please download the latest documentation and try it out. Just extract the archive at a convenient location and open the RadControlsForASP.NET.AJAX.chm file (double check that the "CHM" sub-folder is correctly extracted at the same level as well) and make sure that the file is unblocked as described in the KB. If you still experience the problem please open a support ticket (yes, we do provide support for evaluation users as well) and attach a screenshot of the error you are receiving.

All the best,
Ivo

In the documentation, RadControls for ASP.NET AJAX,

(1) why do the client AJAX $ functions not show up in the intellisense window in VS 2005 when ctl + space is pressed (and yes, I have a RadScriptManager control on the page)?

(2)  why are there references and screenshots for adding RadScriptManager to web.config through the VS designer interface when in fact there is no option for doing so when opening the properties window for RadScriptManager?  What should the full reference be in web.config?

tia,
Mark

On page 487 of RadControls for ASP.NET AJAX, we find:

Rows have an additional set of events to handle drag and drop operations on the client side:

OnRowDragStarted: This event is fired when a row is about to be dragged.
OnRowDropping: This event is fired before a row is dropped.
OnRowDropped: This event is fired after a row is dropped.

none of which exist (though OnRowDrop does), and no documentation to implement drag-and-drop for the RadGrid.

Hello Mark,

The aforementioned events are part of the client-side API. OnRowDrop is a server-side event.

Never mind!  Discovered the assembly that should be referenced is System.Web.ApplicationServices, and renamed the class so it was not the same as the page

Thank you for the step-by-step tutorial...it is a great help in learning about the telerik asp.net ajax controls and VS 2010. I jumped in at section 9: Screen Real Estate Management. I'm following the directions rather than loading the code provided, and everything works fine other than the last part where clicking a linkbutton is supposed to open one of the three windows that are contained in the RadWindowManager. When I click a button the screen refreshes but the window is not opened. 

If I change the property VisibleOnPageLoad to true for the windows, they load fine on load. Clicking a button then does a postback but doesn't seem to actually control the window. 

One other point: the documentation said to drag the RadWindowManager to the bottom of the web page and then click the ... for the Window Property. The Window property wasn't initially available...I had to actually drag a window into the manager before that property was available. Then I could use it to add more windows and configure them. 

Here is the code...do you see anything I'm doing wrong?

    <asp:Table ID="Table1" runat="server" Height="700px" BorderColor="#FF0066" 
        BorderStyle="Solid" BorderWidth="1px" Width="1000px">

Hi Steve,

I cannot see any issues with your code, unless having the first two RadWindows open via the first button only and the third RadWindow via the third linkbutton. Note the OpenerElementID properties of the RadWindows - they are LinkButton1, LinkButton1 and LinkButton3 respectively. This means that a click on the first button (Telerik) will open the first two windows (Telerik and OP2S); a click on the second linkbutton (Google) will perform a postback as there is no RadWindow associated with it; a click on the third (Wikipedia) will open the third RadWindow (Wikipedia). You can see this behavior in a video I recorded: http://screencast.com/t/CZx6xsQeI88x.

If you want each linkbutton to open only one RadWindow you should set the OpenerElementID properties accordingly (most likely to LinkButton2 for the OP2S RadWindow).

As for the windows collection - it is available as soon as you add the RadWindowManager to the page. Of course, you need to add a RadWindow to it before you can set its properties. You can alsternatively use the visual configuration manager through the smart tag if you find it more comfortable. More information on it is available in this help article.


Best wishes,
Marin

Thanks Marin...pretty amazing support. 

The linkbutton number was a typo...corrected that and no change. 

I just created a new page and then added script manager and windows manager to it and the attached image shows that there is now windows collection property available. If I use the configuration manager to add one window, then the property appears and I can use it. 

Your video is great...that is exactly what I expected to happen. 

I'm going to jump back a few chapters in the tutorial and start working in sequence, so won't worry about this lesson until I get back here again.

One thing that may be pertinent...I installed the Q2 2011 NET40 components and then installed a trial version of Sitefinity. At that point VS started pointing to the Q3 components that were installed with Sitefinity. I'm new to all this (VS and Telerik) and got some errors and then reloaded all the DLLs in the bin folder from the Q3 install folder on my hard drive. So someplace along the line I may have some crossed-over references. 

If I have other strange issues I will just uninstall all of it and reinstall one version.

Again, thanks for your response.

Steve

Hi Steve,

It is possible that there has been some mismatch in your project's references, especially if you have some assemblies installed in the GAC and referenced from there instead of from the Bin folder. Please examine the project's references and make sure they all match.

Take your own time and examine the Courseware more throughly and let me know if you have any further questions.


All the best,
Marin

Hi,

the latest (offline) documentation for "ASP. NET AJAX" in CHM format is no longer available via http://www.telerik.com/download/RadControlsForASP.NET.AJAX.zip. Please update, as an offline version is quite convenient!
The download option also disappeared in http://docs.telerik.com/

Hello Norbert,

You can download the offline documentation packages (CHM, Help2, Help3) from your account. Once you go to the UI for ASP.NET AJAX tab, you will see a "browse all product files" link on the right, just above the big blue "download" button. This is where you can find the files now.

Hello Nisim,

There isn't actually a step-by-step tutorial that shows how to migrate each property and method in Telerik UI for ASP.NET AJAX from.NET 1.1 to .NET 4.5.

What I can suggest, however, is that you go through our online documentation and live demos, in order to see how to configure RadWindow and integrate it with other Telerik UI controls. You can also find useful Migration from RadWindow for ASP.NET ("Classic") to RadWindow for ASP.NET AJAX  help article as well as the server-side and client-side API of the control.

Please feel free to open a support ticket/forum thread for any questions or issues that arise regarding Telerik UI controls.

Hello Norbert,

We have migrated our documentation to GitHub, so you can clone the corresponding GitHub repository on your machine from here - https://github.com/telerik/ajax-docs

There is also a wiki section in the repository which provides detailed explanation on how to clone the repository and build the site locally: https://github.com/telerik/ajax-docs/wiki

Note also that this is just a temporary solution and we will research for a better solution on shipping an offline version of our documentaion (a CHM, web site archive, etc.)
