Ajax tab control

There is a issue when we use ajax tab control on 开发者_高级运维a web page and when that page is accessed in fire fox 7.0 version then ajax tabs does not show. can anyone solve this?

Yes i got error in fire fox error console. The error is

Error: uncaught exception: [Exception... "Index or size is negative or greater than the allowed amount" code: "1" nsresult: "0x80530001 (NS_ERROR_DOM_INDEX_SIZE_ERR)" location: "http://localhost:1573/myPage.aspx?_TSM_HiddenField_=ctl00_ContentPlaceHolder1_ScriptManager1_HiddenField&_TSM_CombinedScripts_=%3b%3bAjaxControlToolkit%2c+Version%3d3.0.30930.28736%2c+Culture%3dneutral%2c+PublicKeyToken%3d28f01b0e84b6d53e%3aen-US%3ab0eefc76-0092-471b-ab62-f3ddc8240d71%3ae2e86ef9%3a1df13a87%3aee0a475d%3ac4c00916%3a6e0e9b78%3a9ea3f0e2%3ac7c04611%3acd120801%3a3858419b%3a96741c43%3a38ec41c0%3afde3863c%3a9e8e87e9%3a4c9865be%3aba594826%3a757f92c2%3abae32fb7%3a182913ba Line: 16"]

I was getting the exact same error but on the AsyncFileUpload control. After doing some research, I narrowed the problem down to the actual AjaxControlToolkit itself.

I was running an older version, so I upgraded to the latest version as of November 16th, 2011 and the problem was resolved.

So try the latest version either by direct download or via the NuGet Package Manager in Visual Studio.
