Hi Vladimir,
Here you have a simple example to reproduce the error:
Default.aspx

Default.aspx.vb
Imports Ext.Net

Dim _DocumentID As System.String
Dim _DocumentPDFContent As System.Byte() =Convert.FromBase64String("yourbytearray")
Try
_DocumentID = context.Request.Params("DocumentID")
context.Response.Clear()
context.Response.ContentType = "application/pdf"
context.Response.AddHeader("Content-Disposition", "inline;")
context.Response.BinaryWrite(_DocumentPDFContent)
HttpContext.Current.ApplicationInstance.CompleteRequest()
Catch ex As Exception
Throw
End Try
End Sub
Public ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
Get
Return False
End Get
End Property
End Class
The error only appears in IE8. Under Chrome i can see my document in the preview window.
Thanx!
