Path Property

ViewStateException.Path Property

Gets the path of the HTTP request that resulted in a view-state exception.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

'Declaration
Public ReadOnly Property Path As String

Property Value

Type: System.String
A String containing the path from the request.

This property returns the same value as the PATH_INFO variable in the ServerVariables property. It returns the portion of the path after the host name. For example, in the URL http://www.contoso.com/virdir/page.html, Path would return /virdir/page.html.

The following code example demonstrates how to implement a method that deserializes a base64-encoded string and returns an ICollection collection of property settings. The Deserialize method can throw an HttpException exception that contains a ViewStateException object as an inner exception. The example shows how you can catch an HttpException exception and retrieve the properties from the ViewStateException object.

Private Function LoadControlProperties(ByVal serializedProperties As String) As ICollection

    Dim controlProperties As ICollection = Nothing 

    ' Create an ObjectStateFormatter to deserialize the properties. 
    Dim formatter As New ObjectStateFormatter()

    Try 
        ' Call the Deserialize method.
        controlProperties = CType(formatter.Deserialize(serializedProperties), ArrayList)
    Catch e As HttpException
        Dim vse As ViewStateException
        Dim logMessage As String

        vse = e.InnerException

        logMessage = "ViewStateException. Path: " + vse.Path + Environment.NewLine
        logMessage += "PersistedState: " + vse.PersistedState + Environment.NewLine
        logMessage += "Referer: " + vse.Referer + Environment.NewLine
        logMessage += "UserAgent: " + vse.UserAgent + Environment.NewLine

        LogEvent(logMessage)

        If (vse.IsConnected) Then
            HttpContext.Current.Response.Redirect("ErrorPage.aspx")
        Else 
            Throw e
        End If 
    End Try 
    Return controlProperties
End Function 'LoadControlProperties
