Acessing an ArrayList on the masterpage from a UserControl

Can this be done?

I can access controls such as textboxes, labels etc but i can't seem to access my ArrayList. I have:

Code:

---

ArrayList MyArrayList= (ArrayList)this.Page.FindControl("ListNameArray");

---

I also have int and string values that i need to pass back and forth from the masterpage and usercontrol, how can this be done?


Any help grately appreciated.

Which UserControl? do u mean Content Page of the master page or something else?

If UserControl is Content Page then,
---------------------------------
First thing is ArrayList is not an Control. So, u can't access it using Findcontrol method.

However, It's very easy to get arrayList value. Just define one public variable arrayList in ChildControl (Content Page).

Suppose u have one Master Page 'Main.master' and and a Content Page 'WebForm1.aspx' the following code can give u some idea abt it.

Code:

---

Public Partial Class WebForm1
    Inherits System.Web.UI.Page
    Public arrList As ArrayList

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
     
    End Sub

End Class

---

Code:

---

Public Partial Class Main
    Inherits System.Web.UI.MasterPage


    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    End Sub

    Protected Sub btnCheckArrayList_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCheckArrayList.Click

        If DirectCast(Me.Parent, WebForm1) IsNot Nothing Then
            Dim objClassOfWebForm1 As WebForm1 = DirectCast(Me.Parent, WebForm1)
            objClassOfWebForm1.arrList = New ArrayList()
            Response.Write("created")
        End If
    End Sub
End Class
