Hi all,

I found this forum really useful and I hope this question can be answered here as well.

I have an object declared in a class (a custom user control) and assigned value in a sub; I then try use another sub (a property Get) to retrieve the value and return it to the caller - in vain with VB Studio.Net showing the object is not instantiated at all in the sub. I wonder shouldn't declaring the object in the class makes it persistent throughout the class?? I then tried to make it a Shared object but it won't work either. Does it have to do with loading? Will the object loss it value because the page is postback? Could anyone help please!! this is very urgent work!!


Thanks Heaps!!

excerpts of code:

PublicClass directlink


Inherits System.Web.UI.UserControl


PrivateShared dtContractor As DataTable


... [code omitted]



Private​
Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) HandlesMyBase.Load



'Put user code to initialize the page here


If (Page.IsPostBack = False) Then

sbDataBind()

EndIf

EndSub

PrivateSub sbDataBind()

dtContractor.Columns.Add(New DataColumn("EligibilityNumber", Type.GetType("System.Int32")))

dtContractor.Columns.Add(
New DataColumn("ProviderName", Type.GetType("System.String")))

dtContractor.Columns.Add(
New DataColumn("Contractor", Type.GetType("System.Boolean")))

dtContractor.Columns.Add(
New DataColumn("MaxContractorNumber", Type.GetType("System.Int32")))

...[omitted code for adding data in rows]

PublicReadOnlyProperty SelectedTexts() As DataTable


Get

...
dtRow("Contractor") = Me.dtContractor.Rows(i)("Contractor")
...
EndGet

EndProperty



End Class
