close "x" button question

[Ken]

I using the code in the tabstrip tutorial to put a close "x" button on tabs and it works but is
there any way to actually destroy the tabs instead of hiding or collapsing them?

This is the code from the tutorial...

 Private Function newButton() As RadButtonElement
 Dim radB As New RadButtonElement()
 radB.MaxSize = New Size(12, 12)
 AddHandler radB.Click, AddressOf HideTab
 radB.Font = New System.Drawing.Font("Verdana", 6, FontStyle.Regular, GraphicsUnit.Point, (DirectCast(0, Byte)))
 radB.Text = "x"
 radB.TextAlignment = ContentAlignment.MiddleRight
 'Alignment defines where the button will be placed on the tab
 radB.Alignment = ContentAlignment.TopRight
 Return radB
End Function
Private Sub HideTab(ByVal sender As Object, ByVal e As EventArgs)
 Dim buttonElement As RadElement = (DirectCast(sender, RadElement))
 buttonElement.Parent.Visibility = ElementVisibility.Collapsed
End Sub

Hi Ken,

Thank you for the question.

Yes, you can dispose TabItem instead of hiding it. To do this you have to remove it from the RadTabStrip Items collection. Please, review the following revised HideTab event:

Private Sub HideTab(ByVal sender As Object, ByVal e As EventArgs)
    Dim buttonElement As RadElement = DirectCast(sender, RadElement)
    'buttonElement.Parent.Visibility = ElementVisibility.Collapsed;
    Dim tab As TabItem = TryCast(buttonElement.Parent, TabItem)
    If tab IsNot Nothing Then
        Me.radTabStrip1.Items.Remove(tab)
        tab.Dispose()
    End If

End Sub
