Perform Load upon after click button - vb.net

Question

I am trying to use the panel and buttons to load 2 different forms along with entity framework and ado model stuff. I am trying to load the 2nd form this picture, using the codes running on the first form since they have the same table. but what happen is whenever I close the 2nd form and try to switch on the second user from this form(driverlist), I am still getting the results that I created before on the first user, I kinda think that the 2nd form is not being loaded although I put some code:
Private Sub DriverLicense_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim user_id As Integer = Driverlist.tbxUser_id.Text
Driverlist.db = New [Emme_Subic_Transport_Corporation_Payroll].EmmeSubicEntities
Driverlist.db.UserDetails.Where(Function(c) c.isDeleted <> 1 And c.Id = user_id).Load()
UserDetailBindingSource.DataSource = Driverlist.db.UserDetails.Local
If Driverlist.tbxUser_id.Text.Count < 1 Then
MessageBox.Show("Please Select an Employee ID First", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information)
Drivertest.Panelswitch(Driverlist)
Else
Me.Show()
End If
End Sub
Private Sub DriverLicense_Activated(sender As Object, e As EventArgs) Handles Me.Activated
Dim user_id As Integer = Driverlist.tbxUser_id.Text
Driverlist.db = New [Emme_Subic_Transport_Corporation_Payroll].EmmeSubicEntities
Driverlist.db.UserDetails.Where(Function(c) c.isDeleted <> 1 And c.Id = user_id).Load()
UserDetailBindingSource.DataSource = Driverlist.db.UserDetails.Local
End Sub
I binded the 2nd form through other resources of data binding from the properties but still on the same resources as the first form. Im pretty new to this so please stop putting negatives on my questions. If you think I am bad at this, I know and I am sorry. by the way this is the code from the buttons and panel if that helps. Thanks everyone.
Sub Panelswitch(Panel As Form)
PanelControl.Controls.Clear()
Panel.TopLevel = False
PanelControl.Controls.Add(Panel)
Panel.Show()
End Sub
Private Sub Btntest_Click(sender As Object, e As EventArgs) Handles Btntest.Click
Panelswitch(Driverlist)
End Sub
Private Sub Btntest2_Click(sender As Object, e As EventArgs) Handles btntest2.Click
Panelswitch(DriverLicense)
End Sub

There are number of things I would avoid, just looking at your pictures, but that goes beyond your question.
Secondly, agreed with the comment, you should revise your question further (I see you tried, but still, it's neither complete or clear).
If I understand correctly, you have container PanelControl, which you fill either with a form DriverList or DriverLicence. I just want to make sure - are you sure you have your instances corectly set? Because I would expect that the switch would act only for displaying correct form, but should behave differently for the [persistent] list DriverList and DriverLicence, which should be probably a new instance every time you want to add a licence. But this code is not shown, just guessing the problem might be along those lines. There are quite few design possibilities, I guess.
Simplified, the point is:
Private Sub Btntest2_Click(sender As Object, e As EventArgs) Handles btntest2.Click
Dim DriverLicenceInstance as new DriverLicence
Panelswitch(DriverLicenseInstance)
End Sub
I also think, that you might have your binding set incorrectly for the 2nd form, the DriverLicence. I'm not proficient in .NET binding, but it seems to me that you declare the bindings as two separate things (comes from the copying the code?). But what you probably need to do is to use the same binding source for both parts. See here: A-Detailed-Data-Binding-Tutorial.
