Problem with DefaultButton in Q2 2012

Did this issue come back to life in Q2? After upgrading to Q2 the issue described here was noticed in my login page which contains two radTextboxes and a radButton placed within an asp panel (default button set to radButton). If you enter a user name then use tab to enter the password, hitting enter on your keyboard (while radTextbox has focus) does nothing. Only after hitting the enter button twice or using the mouse to click back to the first textbox makes the enter key work. I tried setting the EnableSingleInputRendering to false but this did nothing. If I replace the radTextbox with an asp textbox everything works as expected.

Client Side Validation After Exiting Each Cell

I have a spreadsheet-type grid using GridBoundColumn and InPlace edit and I want to do a client-side numeric validation after the user exits each cell. I am not able to use a GridNumericColumn because of issues described here. Is there some kind of OnCellExit event that I can use? Thanks.

Cascading DropDownList's in RadGridView EditForm

So I've been Googling this and have found various articles pertaining to it, but none of the solutions seem to work. The screen I'm working on has a grid view for vehicle listings. When a listing is edited, the user can edit the Vehicle Type, Manufacturer & Model.

When a user selects Vehicle Type, the Manufacturer DropDownList will rebind, when a user selects a Manufacturer, the Model DropDownList will rebind. Unfortunately, I keep getting this error: 'DropDownList2' has a SelectedValue which is invalid because it does not exist in the list of items.

Maybe I have the binding order mixed up. Here is my code:

<telerik:RadGrid ID="radVehicleListingGrid" runat="server" AllowAutomaticDeletes="True" AllowAutomaticUpdates="True" CssClass="AdminGridView" DataSourceID="sdsVehicleListings" GridLines="None" Skin="">

support for notification button/menu?

any ideas on how to accomplish something like this?

I could create a series of icons 1-100 but that would be kinda crazy.

DecimalSeparator, GroupSeparator properties for GridNumericColumn

Hi,

RadNumericTextBox controls contains DecimalSeparator and GroupSeparator properties in NumberFormateSettings collection. But these properties are not available in RadGrid's GridNumericColumn. Unfortunately GridNumericColumn's DataFormatString property also not working correctly. How can I achieve these properties behaviour in GridNumericColumn? (Even I'm ready to develop CustomRadGrid control also.)

sys.application null or not an object

Hi

I recently purchased RadControls for Asp.net ajax, and installed it on my machine. I use VS2005 and VS 2008, with .NET Framework 2.0 and 3.5 respectively. I added a RadScheduler control to one of the usercontrols in my project and added a script manager on to the control. After I run the page, I get a Sys.Application is null or not an object error, followed by many other javascript errors. I am unable to use Radcheduler's navigation events. I am not sure if its beacuse to this. please reply.

Question on Data loading

Is it correct that the AutoCompletebox loads the entire data, then filters it? I would have thought that it would use a parameterized query to limit the loading. The scenario I would use this for has several thousand rows ( and always increasing). Not sure which would be worse, making the page initially wait while everything loads, or repeated hits on the database as the user types.

Does the loaded data end up in Viewstate? The apps Viewstate is already getting really huge.

Thanks

WebParts && Nested RadDocks

Thank you in advance...

I am working on a project in which I would like to utilize RadDocks to create a user customizable environment. The host website is a Sharepoint site that consists of MOSS host pages that contain numerous User controls.

I was wondering if the RadDock controls can be used in the MOSS host pages to contain WebParts?

Secondly... is it possible to have nested RadDocks?

i.e.

        MOSS Host Pages
            - RadDocks (containers for multiple User Controls on host page)
                - User Control
                    - RadDocks (container for multiple asp.net controls)
