Cross Page Post Back
I'm hoping someone can help me with a Cross Page Post Back
In the source page, I have declared a Public Property:
Public ReadOnly Property userAccountID() As Int32
In the Destination Page, I have declared a PreviousPage.
<%@ PreviousPageType VirtualPath="~/secure_members/accountDetails.aspx" %>
I am attempting to set the value of a control on a DetailsView control, inserting
Protected Sub DetailsView1_ItemInserting(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.DetailsViewInsertEventAr gs) _
e.Values("UserName") = User.Identity.Name
e.Values("registrationEventID") = "1"
e.Values("registrationAccountID") = PreviousPage.userAccountID
When I run the page, I get this error:
Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Line 14: e.Values("registrationAccountID") = PreviousPage.userAccountID
What am I missing? When i typed the inserting object for the Account ID (e.Values("registrationAccountID") = PreviousPage.userAccountID), the userAccountID popped up in the intellisense so I thought it would work.
Any help is appreciated!
