It seems I've uncovered a bug in the compression module, or I may be doing something wrong.

It seems that when you use it to compress ViewState, it fails in the following scenario:

Main page, compression module enabled to compress viewstate (I actually have not enabled it to compress the viewstate, but its doing it anyway, without the browser file). On that page, a button opens a RadWindow, which calls another page. When the RadWindow is closed, the main page returns a javascript error saying that the ViewState doesn't match. This makes sense because the second page in the RadWindow modified the variable that's storing the compressed viewstate, and now they don't line up. This seems to be the case in both modes, hidden variable and session.

Is there any solution to this, or am I doing something wrong?

Thanks in advance,

Alex T

Static Reflection

All,

I realize that this is more of a request than a bug, but I consider anything using strings to do reflection as a bug. It is bad, bad, bad...especially when we have such things as Static Reflection available to us in 3.5 with Expression<T>. The reason is that you don't get any compile time checking. Instead, you don't find out that you mispelled something or a property has been deprecated until run time when you finally click on that page where the grid lives.

Anyways, I am wondering what the plan is to change your columns to use Static Reflection versus using strings as DataFields. The reason that I ask this, besides it really bugging me, is that I am working on an implementation of our own bound column that uses it. Since I can't override its functionality as easy as you, especially because of all the internal calls, I will request that you make your grid columns start using Static Reflection. In case you don't know what this is, instead of mapping an object to a string representation of the property, you can actually map it to a compiled version of it using lambda. Below is an example of what I would love to see. A Fluent Interface would be my next request.

var amphireGridBoundColumn = new AmphireGridBoundColumn<Product>().MapDataField(x => x.CasePrice);

amphireGridBoundColumn.HeaderText =

"Case Price";

radGrid.MasterTableView.Columns.Add(amphireGridBoundColumn);

Thanks for taking the time to read this and I hope that you can implement it soon.

Q1 2009 - Uninstall Labeling Bug

Hi Guys,

This is a minor bug that does not effect the execution of your products, but it is a bug none-the-less.

In the Windows Uninstall window your products are not consistently listed. Currently they are listed as follows:

RadControls for Silverlight Q1 2009
RadControls for WPF Q1 2009
Telerik RadControls for ASPNET AJAX Q1 2009
Telerik RadControls for WinForms Q1 2009

Your names have always been consistent in the past either ALL starting with RadControls or Telerik so they are grouped clearly.

~Mike

Binding data in a DetailTable

I have a hierarchial grid that displays applications on the top level. Under each application I display the users for that application. What I want to do is have the username linked to the page for that user. I thought it was a fairly simple issue to solve but after a few hours trolling the forums and digging through the documentation I still can't figure out how to accomplish what I need.

I need to set the NavigateUrl for each user server side because we encrypt the querystring on the URL link to a user. For a normal grid I simply subscribe to the OnDataBound event for the grid and in that method I get the Hyperlink instance and set it using information from from the row (as seen here).

I tried subscribing to the OnDataBound event on the DetailTable GridTableView but the event never fires.
I know this could probably be accomplished by encrypting the data and putting it in the object bound for the detailTable for each user before the databind but I'd rather do it by not modifying the object that I bind to.

Is this possible?
Thanks.

Prototype compatibility

I am using RadScheduler (version 2008.3.1125.20) with prototype.js on the same page.

I attached an example. When you move App3 to a timeslot 10am-11am, you get the following error:

_87.get_start() Object doesn't support this property or method

And it locks the control.

I hope it gets resolved soon. It is really causing us a lot of frustration.

Thanks,
Oleg.

Telerik.WebControls and Ajax ModalPopupExtender and RadUpload

A bit of a mouthful on the title, sorry about that, but I want to make sure you get a slight idea of what I am trying to achieve.

Ok, so a brief description.
I have a RadUpload Control inside a AJAX ModalPopupExtender Panel. This works fine in IE 7, but in FireFox (version 3.0.7) the 'select' button will not work. All the other buttons do, but that one won't. In IE 7 though, it works fine.
I haven't tested it in any other browsers yet.

The other issue is to do with the RadUpload File validation. I checked http://demos.telerik.com/aspnet/Upload/Examples/CustomValidation/DefaultCS.aspx?RadUrid=aadb5481-df77-46ad-8602-87a54ed7c12b for custom validation. The thing that keeps stopping me getting any further is the reference to Telerik.WebControls.
I can not find any documentation anywhere telling me anything about this reference. If I go to 'Add Reference' I can see Telerik.WinControls, but no mention of WebControls anywhere. If I try to add the imports Telerik.WebControls, it just moans saying it can not find it.
I need the import because without it I can not use ValidateFileEventArgs which is really what I need to use.
Please can someone point me in the right direction. If you require a code example, I will put some in here.

Thanks,
r3plica
