Hi there,

Is there any solution to this problem ?

I have an issue in telerik control like RadLIstbox or Combobox .there is one method set_text which is not supported in the IE9 browser and other browser are working fine.

SCRIPT438: Object(RadListbox) doesn't support property or method 'set_text'

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:

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)

radCaptcha in ASCX user control does not validate on first attempt (but does on subsequent postbacks)

Dear Telerik

Please could you advise if there is a workaround for my scenario, which is causing inconsistent validation behaviour in the radCaptcha control.

I have an ASCX user control in which a radCaptcha is added DECLARATIVELY in the ASCX markup. I use the <captchacontrol_id>.Validate and Page.Validate(<myvalidationgroup>) functions in my server-side button handler. On the user's first attempt to use the page to postback with validation, the IsValid property switches incorrectly to False as a result of running these functions, even if the captcha code is entered correctly. However, if the user tries again, the validation is successful, with the expected IsValid value of False being shown.

I do not believe this is directly a problem with my code, because this behaviour is only seen in the situation when the HttpRuntime process has to start up to serve the page. If the process is already running from previous requests, the 'first attempt failure' problem I describe above does not occur. It is as though the httphandler in Telerik.Web.UI.WebResource.axd is not ready until after the first postback. I have tried using the HttpHandlerUrl property to see if this serves to 'preload' the httphandler, but this does not seem to make any difference, e.g.:

myCaptchaId.HttpHandlerUrl = "~/Telerik.Web.UI.WebResource.axd"

I have also tried moving the <captchacontrol_id>.Validate and/or Page.Validate(<myvalidationgroup>) functions to different places in the page life cycle before the button handler runs, and in various 'If Page.IsPostBack' clauses, but this also is not useful. The problem of the initial validation failure remains consistent.

I am wondering if you could advise me about the best way of resolving this issue, as I believe I have now spent more time than is reasonable (several days) trying to resolve the problem. For example, can you me of any workaround for my scenario that would ensure that the radCaptcha control and the httphandler would be ready to perform the correct validation behaviour on the first attempt?

Thankyou for your advice on the problem.

Regards

Paul
