Using Panel Open Forms

Hello,
I’m currectly studing the bunifu and trying to create test programs for education purpuse only .
I have a question if someone can help me out. I’m using VB.net 2015 and mysql
I’m trying to make this:

Form1(AdminMenu) is my main form.
Form2(UsersAddCP) is my sub form

In form1 i had added Panel and i want to open Form2 inside of it.
Inside the form2 i have 7 textboxes 4 checkboxes and 1 button (Form2 is register user)
And i have a problem when i fill all fields and press the button from the Form2 , in mysql database is created new record but all fields are empty, it looks like whatever i type is not readed. But if i set in textboxes default value text in mysql create it with this information.

In form1 button to open form2 in panel is like this:

Dim form2 As UsersAddCP= New UsersAddCP()
        form2.TopLevel = False
        form2.TopMost = True
        Dim form1 As AdminMenu = CType(Application.OpenForms("AdminMenu"), AdminMenu)
        Dim panel1 As Panel = CType(form1.Controls("panel1"), Panel)
        panel1.Controls.Clear()
        panel1.Controls.Add(form2)
        form2.Show()

What is the problem that when i type information in textboxes and click the button in Form2 is not reading anything.
Please note if i make Form2 to show as normal open new window form and fill the textboxes and checkboxes all records are added correctly. I’m having only the problem with Panels . Please someone can help me out, i cannot find any guide or someone to help me.
I would be glad if someone make video about this it will help a lot of people like me that are trying this.
I must note that in form2 button save uses RegisterUser() module to insert all the information
Here is my code :

Public Sub RegisterUser()
        Try
            With cmd
                .Connection = conn
                .CommandText = "INSERT INTO users (uname,upassword,ucode,ucreate,utools,usearch) VALUES (@user,@pass,@ucd,@crt,@uto,@usrh)"
                .Parameters.AddWithValue("@user", UsersAddCP.TextBox1.Text)
                .Parameters.AddWithValue("@pass", UsersAddCP.TextBox2.Text)
                .Parameters.AddWithValue("@ucd", UsersAddCP.AdminCheck.Checked)
                .Parameters.AddWithValue("@crt", UsersAddCP.CreateCheck.Checked)
                .Parameters.AddWithValue("@uto", UsersAddCP.ToolsCheck.Checked)
                .Parameters.AddWithValue("@usrh", UsersAddCP.SearchCheck.Checked)
                .ExecuteNonQuery()
                .Parameters.Clear()
                .CommandText = "INSERT INTO personal (pacc,pName,pEmail,pYazaki,pPhone,pPosition) VALUES (@user,@name,@email,@yazaki,@phone,@position)"
                .Parameters.AddWithValue("@user", UsersAddCP.TextBox1.Text)
                .Parameters.AddWithValue("@name", UsersAddCP.TextBox3.Text)
                .Parameters.AddWithValue("@email", UsersAddCP.TextBox4.Text)
                .Parameters.AddWithValue("@yazaki", UsersAddCP.TextBox5.Text)
                .Parameters.AddWithValue("@phone", UsersAddCP.TextBox7.Text)
                .Parameters.AddWithValue("@position", UsersAddCP.TextBox6.Text)
                Result = .ExecuteNonQuery
            End With
        Catch ex As Exception
            MsgBox(ex.Message)
        Finally
            If Result > 0 Then
                MessageBox.Show("Sign Up Successful", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information)
            Else
                MsgBox("Failed to register user!")
            End If
            cmd.Dispose()
            If conn IsNot Nothing Then
                conn.Close()
            End If
        End Try
    End Sub
