[Solved] Stacking tabs when viewport size changes

Hello, can the TabStrip control alter it's orientation based on the viewport/device it's presented on? Let's say I have 5 tabs on a page and when I view this page on an iPhone or Android phone can the tabs align themselves in a stacked fashion (all-closed state). In short, how mobile-friendly is this control - we don't want users to have to scroll horizontally on a mobile device. if this is possible can it be achieved through configuration of the control or is it more of a hand-coded task?

Thanks.

List Uploaded Files and Download FIes

I was able to successfully build a web form and using the ajax uploader control, upload files to an azure blob container (i.e. MyFiles-Blobs/hsc/so/file.txt). Now I would like the user to come back to the form and view the uploaded files and download the files at a later time. Can the uploaded control do this and if so is there an example I can use. Or is there a better way of doing this task? Thanks for the help with this request!

Sys.InvalidOperationException: Could not find UpdatePanel with ID '...'

Hi,
I have just upgraded an app from RadAjax Classic to the latest version for ASP .NET AJAX. I have been through the process of switching to the RadAjaxManagerProxy, adding ajax settings programatically in Page_Load instead of Page_Init etc.

Now most of my ajax updates are now working but some are not.

After certain updates the page fails to update and I get the following javascript error:

Error: [Exception... "'Sys.InvalidOperationException: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'someAjaxifiedControlPanel'. If it is being updated dynamically then it must be inside another UpdatePanel.' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "<unknown>" data: no]

The particular control that this error message is complaining about is not part of the current update and is not currently visible. With RadAjax Classic this didn't matter, so I don't think this is the issue.

What causes this error?

Disabling "RowClick" for one column in a grid

I have set <ClientEvents OnRowClick="RowClick" /> to fire when a row is clicked. I have a Server-side checkbox on the row that I would like to exclude from this javascript event. Does anyone know if there is a way to do this and how?

Basically, I am trying to have a checkbox on the Grid row that when checked doesn't fire a server-side or client-side event. When I click on a button on the page, I'd like to cycle through the grid and get the items with a checkmark.

Thanks!
