Dynamic Tab Control Inheritance

[spach]

I've got a tab control and want to dynamically add tabs depending on the output from a database.

I can easily add a new tab, however I want to inherit the controls and layout from the initial tab.

Can anyone help me???

Many thanks in advance

You should define a UserControl that contains all the controls you want to display on a tab. You should then define an inherited TabPage class that, when created, creates an instance of your UserControl and displays it, e.g.

Public Class TabPageEx
    Inherits System.Windows.Forms.TabPage

    Private WithEvents uc As New UserControl1

    Public Sub New()
        Me.uc.Margin = New Padding(0)
        Me.uc.Dock = DockStyle.Fill
        Me.Controls.Add(Me.uc)
    End Sub

End Class

Now you can create instances of your TabPageEx class and add them to the tabControl instead of regular TabPages.

Many thanks for your help, Seems straight forward when you think about it!!

I would appreciate it if you could share your method for dynamic tabpages based on database output.
thanks

Hi,
I never did implement it as I needed differing controls within the control!

Sorry I can't be of more help.

Thanks

tab class with usercontrol

Hi Experts,
i'm a beginner to vb. can anyone plz help me in solving this issue.

i have user control defined as:
Public Class UserControl1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
TextBox1.Text = "asdf"
End Sub
End Class

and created a tab class as follows:
Public Class MyTabControl
Inherits System.Windows.Forms.TabControl
Private WithEvents uc As New UserControl1()
Public Sub New()
Me.uc.Margin = New Padding(0)
Me.uc.Dock = DockStyle.Fill
Me.Controls.Add(Me.uc)
End Sub
End Class


Now on my main form i have a button to add tab with name from textbox.

Public Class Form1
Dim f1 As New MyTabControl()

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
f1.Controls.Add(New TabPage(TextBox1.Text))
End Sub

The error thrown is: Cannot add 'UserControl1' to TabControl. Only TabPages can be directly added to TabControls.

can anyone plz let me know what mistake am i doing here.

Read post #2 again by jmc, you made a class that inherited from tabcontrol instead of tabpage.
