From time to time I see the following error caught in our system's error logs:

The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters.
   at System.Convert.FromBase64String(String s)
   at Telerik.Web.UI.CryptoService.Decrypt(String encryptedString, String password)
   at Telerik.Web.UI.AsyncUploadHandler.GetConfiguration(String rawData)
   at Telerik.Web.UI.AsyncUploadHandler.EnsureSetup()
   at Telerik.Web.UI.AsyncUploadHandler.ProcessRequest(HttpContext context)
   at Telerik.Web.UI.HandlerRouter.ProcessHandler(String handlerKey, HttpContext context)

   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

I haven't been able to tie it t any specific input or activity. Any idea what might be causing it?

Hi friends,I have Telerik Treelist control which works perfectly when I use EditFormType="AutoGenerated"
but when I use EditFormType="Template" with a customized template my template for insertion is not showing when I click in the Add(+) image.The template for edit works fine.
When I use breakpoint in the RadTreeList1_ChildItemsDataBind event I found this error.
I have a textbox and checkbox in the template.
The aspcheckbox is creating the problem.I tried with the following solution of using RadTreeList1_ItemCommand()
System.Collections.Specialized.ListDictionary newValues = new System.Collections.Specialized.ListDictionary();
    newValues["AccountName"] = string.empty
    newValues["IsDirect"] = true;

Hi Team,

User Action : User will do a single click and modify the cells and he will go the next page of the RadGrid by click on the pager. User will modify the values in the next page and so on and when user comes back to the previous page the user should see the modified values. There should not be any popup or any warning when the user moves from one page to another page using pager.



How to get the modified values or modified rows with values before the user moves another pager using the pager of the RaGrid in the codebehind ? Is there any event where we can get the modified rows?

Is there anyway to attach the sample code which we are working

Hello,
I have the following scenario. I have an empty RadGrid and I want to inline insert items. I also have a button and on the button click I need to insert all the items from the RadGrid into a database.
I want to use a DataTable that is placed in a session object as a datasource for my RadGrid. On every RadGrid insert item event I want to add a row into my session DataTable. And after a button click I am going to take each row from the DataTable and insert it's data into an EntityObject (which is in my case called "Product") which I'm going to insert into a database with context.SaveChanges() method.
What I can't accomplish is to store temporary data in a DataTable that is stored in session object.

Please, is there any example of something similar?
