I've just tried this with a custom handler (similar in nature to the demo).
I have also added the property to disable the chunks:
Works great locally. No temp folders or files are created.
When I deploy to an IIS server, however, I get the same APP_DATA can't create permission problem that I had before.
What is going on??
My handler is pretty simple and I do everything that was suggested in this post + others regarding this situation and this property.
Imports Telerik.Web.UI
Public Class CustomRadAsyncUploadHandler
Inherits AsyncUploadHandler
Implements System.Web.SessionState.IRequiresSessionState
Protected Overrides Function Process(file As Telerik.Web.UI.UploadedFile, context As System.Web.HttpContext,
configuration As Telerik.Web.UI.IAsyncUploadConfiguration, tempFileName As String) As Telerik.Web.UI.IAsyncUploadResult
'The BASE process saves things to TEMP location/folder. We don't want that.
'Return MyBase.Process(file, context, configuration, tempFileName)
Dim iDocumentID As Int64? = Nothing
Dim result As CustomRadAsyncUploadResult = Me.CreateDefaultUploadResult(Of CustomRadAsyncUploadResult)(file)
Dim config As CustomRadAsyncUploadConfiguration = TryCast(configuration, CustomRadAsyncUploadConfiguration)
If config IsNot Nothing Then
'Save our file to the TEMP area for documents
SetData.SetDocumentData.SetTempDocument(config.eDocmentCategoryType, file, config.gBatchID, config.eDocumentLocationType, iDocumentID)
'Then... pass on some vital information for the FileUploaded handler
result.iDocumentID = iDocumentID
result.eDocumentLocationType = config.eDocumentLocationType
result.sAjaxManagerClientID = config.sAjaxManagerClientID
End If
Return result
End Function
End Class
