Controls on controls

I have two controls in a custom module. Control 1 is view. Control2 is search. User selects value on Control2 and I want to update Control1(View). I cannot find syntax to change values on Control1 from Control2. The following is function on Control1 that is called from Control2 after pageInit and load on Control1. I have tried many many ways to findControl but all fail.

'Function on Control1 called from Control2 after Control1 PageInit/load:

        Public Function loadformValues(ByVal intValue As Int32)

            Dim objControl as Control1 = Page.FindControl("Control1")
            Dim tb As New TextBox
            tb = objControl.FindControl("tbsecure_lastname")' fails at finding textbox on Control1
            tb.Text = intValue

        End Function

Thank you for any assistance

Re: Controls on controls

A better way to do this is to create a Public Property in Control1 called SecureLastName (which is a wrapper for the text box's text property) for example

Public Property SecureLastName as String
    Get
       Return tbsecure_lastname.Text
    End Get
    Set (Value as String)
       tbsecure_lastname.Text = Value
    End Set
End Property

And then modify the code in Control2

       Public Function loadformValues(ByVal intValue As Int32)

            Dim objControl as Control1 = Page.FindControl("Control1")
            objControl.SecureLastName = intValue

        End Function

If you need to expose all the properties of the control expose the control as a Property

Public ReadOnly Property SecureLastName as TextBox
    Get
       Return tbsecure_lastname
    End Get
End Property

This will allow you to do the following

       Public Function loadformValues(ByVal intValue As Int32)

            Dim objControl as Control1 = Page.FindControl("Control1")
            objControl.SecureLastName.Text = intValue

        End Function
