Hi,
I would like to suggest that you extend the RadGrid GridEditFormItem.ExtractValues method to support updating any business object. It could use reflection to find any properties that match the names of data bound columns.

This would make the data binding very powerful! If you don't use declarative databinding getting the values back into your database is a pain. But being able to simply update a LINQ generate entity object with a single method call would be a huge improvement.

So instead of doing :-

    
                Hashtable values = new Hashtable();  
        
                item.ExtractValues(values);  
        
                C.CategoryValue = (string)values["CategoryValue"];  
        
                C.Selectable_ = (bool)values["Selectable_"];  
        
            // etc. for all fields

You could do :-

    
                item.ExtractValues(C);

Intermittent issues with RadDecorator

Hi all

I am using Q1 2009 and I keep getting intermittent behaour with skinning of my pages.

I am using Usercontrols and RadAjaxManager skin Office2007. I would deploy the App ( incedently now when I deploy I have to visit each page doesn't seem to jit properly anyway ) , login and test all ok. login again this time different things would not skin. RadPanelBar, RadDockingZone, RadGrid. I could then try things like reboot server and client PC. clear browser caches and they start to work. All very odd, anyone got any bright ideas ?

FullScreen Slow - 5 Seconds or so - Normal?

Just wondering if it's normal for the fullscreen toggle to take up to 5 seconds or so running the samples (3.1314.35).

No biggie, but in lookin at it compared to an older editor we are replacing it was basically immediate so I want to make sure I'm not doing something wrong.

What should be expected?

Thx

ACTUALLY, running some of the samples with more toolbars turned on, it seems to be running as long as 10 seconds ;)

Security warning on folder creation in IE7

Hi All,

I am using RadEditor Q3 2008 (02.1001) and when, in a ImageManager or DocumentManager dialog, I want to create a new folder I get in IE7 a warning about a scriptprompt (for entering the new folder name).

In a previous version the foldername had to be entered in the dialog itself, and I saw the new version (Q1 2009) using a RadWindow as a prompt, but upgrading is currently not an option.

Is there a way to circumvent / surpress this issue server-side, or use a radwindow instead of a javascript prompt?

Thanks in advance,

Regards,

Roland

PanelBar DataBinding Subcontrols

I have a PanelBar that is databounded to a list via the code behind. Inside the PanelBar I want a template that has a control inside it and the control is databounded OnItemDataBound of the PanelBar by getting a value from the PanelBarItem. The issue I'm having is that I can't find the control to bind to it. The code throws a null reference exception on line 27 of the code behind below.

Default Sort Order Anytime Field is Sorted

Is there a way to have the grid default to Descending when a sort is used. I don't want the grid to come up sorted by default. I simply want it to use Descending first as the default sort direction. I was surprised that there wasn't a property in the sort settings to do this. Am i missing something?

[Solved] Toolbar error in IE8

I have a page with a RadToolBar which works perfectly in IE7 and Firefox 3 but having installed IE8 it throws a script error when a button is clicked.

I have created a stripped down page with just a toolbar in and I am getting the same error. The error occurs when clicking on a dropdown item from a RadToolBarSplitButton or a RadToolBarDropDown.

            </body> 
        
            </html>

According to the IE8 script debugger the error is:

    
              Invalid argument.  Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_HiddenField&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d3.5.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3a0d787d5c-3903-4814-ad72-296cea810318%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2009.1.311.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3af48f6488-574a-46fe-9b15-624f013d8c03%3a16e4e7cd%3af7645509%3a24ee1bba%3a1e771326%3aa7e79140, line 4240 character 1

The line the error points to is

    
            this.get_animationContainer().style.zIndex=this._originalZIndex;

The error is thrown as the dropdown closes.

I'm using Visual Studio 2008 and the project is using .NET Framework 3.5 SP1 with the 2009.1.311.35 version of the Telerik.Web.UI.dll from the Bin35 folder.

Is this a known error and is there a fix for this?

Thanks,
Nick
