Question

I’ve a link button:

<asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" Text="View" PostBackUrl='<%# Eval("Name", "../Image/Uploaded/{0}") %>'>

The Eval value is based on what image is loaded to the formview.

For example, I want to view the Panorama.jpg image and while I am clicking that linkbutton, the error shows:

The HTTP verb POST used to access path '/Image/Uploaded/Panorama.jpg' is not allowed.

I’ve tried using this code to solved but it is the same:

Dim imgUplPath As String = Request.PhysicalApplicationPath & "../Image/Uploaded/"
Dim f2 As New FileIOPermission(FileIOPermissionAccess.Read, imgUplPath)
Try
    f2.Demand()
Catch s As SecurityException
    Console.WriteLine(s.Message)
End Try

Anyone can help me, please? Thanks a lot

Answer 1

You are trying to do a POST request to an image resource – jpg. That’s not valid; there’s no handler for POST requests for jpg resources.

Perhaps what you are looking for is to link right to the image URL, instead of using the PostBackUrl of a LinkButton
