HI
I use stylesheetmanager to load my styles
but now I need to change the logo for my server side events
so I put this on pageload

If Not Session("folderStyle") = Nothing Then

Dim link As New HtmlLink()

link.Href = Session("folderStyle")

link.Attributes.Add("rel", "stylesheet")

link.Attributes.Add("type", "text/css")

Page.Header.Controls.Add(link)

End If

So when I load the new styel I overwrite the definitions in the common stylessheetmanager references
--
the problem is that Stylesheetmanager load the styles at the last row of html before </head>tag
so the result is

<link href="/css/ProdottiManzi/English/stile.css" rel="stylesheet" type="text/css" />

<link href=

"/Telerik.Web.UI.WebResource.axd?compress=1&_TSM_CombinedScripts_=%3b%3b%7c634859195287498065%3a94dbb91c%3a58260d52%3a267fe04e%3bTelerik.Web.UI%2c+Version%3d2012.2.912.40%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ait-IT%3a6aabe639-e731-432d-8e00-1a2e36f6eee0%3aed2942d4%3a53e1db5a%3ad126a8ef%3a92753c09%3a91f742eb%3a4f5793d0%3afe53831e%3bTelerik.Web.UI.Skins%2c+Version%3d2012.2.912.40%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ait-IT%3ab0377b55-749e-4497-8000-b9ed5bce0744%3a6856648a%3af7a27b73%3a261be263"

type="text/css" rel="stylesheet" /><title>

</title></head>

and as you can see my definition is before and not after
telerik sheets and mine used in stylesheetmanager

is there some property to change or my I add a style reference at runtime ?
thanks

[Solved] Dynamically created TabStrip losing PageView on postback

I have a dynamically added usercontrol that dynamically creates a TabStrip and associated PageViews from a database. For SEO purposes what I want this to do is create the PageViews for some of the tabs initially but also have some of the Tabs that will dynamically add thier PageViews on TabClick. Some of these also get additional user controls added to the PageView.

The problem is that the tabs with PageViews work fine until I click one that loads another page OnPostBack. Once the new PageView is dynamacally added OnPostBack I loose all of the ones that were originally created.

I believe I need to use the multipage PageViewCreated event to persist the dynamically created controls inside a RadPageView such as what is shown on this demo http://demos.telerik.com/aspnet-ajax/tabstrip/examples/applicationscenarios/loadondemand/defaultcs.aspx.

My problem is I am adding the content to the initially created PageViews by placing it into a Literal using Controls.Add which works fine initially. The problem is I can't seem to find it using e.PageView.FindControl to persit it in the PageViewCreated event below which always shows "PageView not found" in the code below.

Any help would be greatly appreciated!

Thanks in advance,
Dave

Identifying when a user saves without changes

When a user modifies a schedule is there a way to detect on the server if the appointment and the modified appointment are the same, in other words, there are no changes? Or client side is there a way to simply call the cancel submit when save is clicked with no changes?

I cannot find any way to do a compare on the appointment and the modified appointment that is built in and would cover all information passed from the form.

Thanks!

The process cannot access the file because it is being used by another process.

I have 5 web applications running on the same server. The code is identical between each application, differences being web.config, theme, etc. Three of the applications upload files successfully while the other two fail with the following event being logged : "The process cannot access the file because it is being used by another process."

I'm fairly convinced this is an environmental problem, but I've triple checked and all of the applications are set-up the same in IIS and the permisssions on the folders are also the same.

Also, the files are uploaded to the temp directory and remain as random named files, and the error occurs when I clcik the "Save Documents" built in button.

Does anyone have any idea's on what could be causing this?

Thanks,
Joe

Reset Scrollbar to Top

I have a paginated RadGrid populated server-side via NeedDataSource. Pagination is handled via AJAX. When we scroll down the results in the grid, hit the next page button, we want the scroll bar to be reset back to the top of the gird. Currently, it is persisting to its last position.

I've tried both solutions in this post: http://www.telerik.com/community/forums/aspnet-ajax/grid/reset-scrollbar-to-top.aspx

Is there a solution for this? And why doesn't SaveScrollPosition="False" work? We are using version 2011.1.519.35 of Telerik.Web.UI.

Thanks.

[Solved] AsyncUpload iOS 6 null InputStream

iOS 6 allows for photos and videos to be uploaded via safari. Everything works well on the AsyncUplod including the server side FileUploaded event. However, when I try to access the InputStream via e.File.InputStream I get a null / file not found exception. I can watch the temporary folder where the file gets uploaded to and no file is ever written there. All of the server side and client side events fire like normal without the file ever being written to the server.

Am I missing something here or is there a bug for safari on the iPad?
