I'm working on having two forms that communicate together. In order to do this, I am passing public value from the source page. Here's how I did it:
In the source page I have:
Public ReadOnly Property CurrentCity() As String Get Return txtboxfake.Text End Get End Property Then under page_load of the page I have: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load txtteam.Text = PreviousPage.CurrentCity txtboxdate.Text = Calendar1.SelectedDate End Sub
For some reason I keep getting an error that says "NullReference exception unhandled by user code" that points to txtteam.text = PreviousPage.CurrentCity.
