                                    I created a FluentDesign Form, where I add a XtraUserControl1 as TabForm. After that I pressing on a button in hamburger menu, to create a TabPage with specific name and control. After creating some controls inside TabPage, I want to close them though close button in TabFormControl, but nothing is happening.

                                    Imports System.Threading Public Class Form1 Private m_tabControl = New XtraUserControl1 Public Sub New() InitializeComponent() FluentDesignFormContainer1.Controls.Add(m_tabControl) m_tabControl.Dock = DockStyle.Fill End Sub Private Sub AccordionControlElement2_Click(sender As Object, e As EventArgs) Handles AccordionControlElement2.Click Dim l_control = New Views.ATX_DBA_TestEntitiesView.ATX_DBA_TestEntitiesView Dim l_controlName As String = AccordionControlElement2.Text m_tabControl.AddTab(l_controlName, l_control) End Sub End Class ------------------------------------------------------------------- Public Class XtraUserControl1 Public Sub New() InitializeComponent() End Sub Public Sub AddTab(ByVal pi_ControlName As String, ByVal pi_Control As Control) Dim l_TabPage = XtraTabControl1.TabPages.Add(pi_ControlName) l_TabPage.Controls.Add(pi_Control) End Sub End Class

                                  Hi Jens,

                                  Thank you sharing the code snippet. However, this information is insufficient to say precisely why this happens. Would you please isolate this issue into a small compilable project? This will help us narrow down the issue and find its cause as soon as possible.
                                  I look forward to your reply.

                                  Its not really small, but I think you can see what happened.

                                Yes, by default, clicking the XtraTabControl close button has no effect. You can handle the XtraTabControl.CloseButtonClick event to implement the required behavior (for instance, hide/remove the currently active tab page). For example:

                                Private Sub XtraTabControl1_CloseButtonClick(sender As Object, e As EventArgs) Handles XtraTabControl1.CloseButtonClick Dim arg As ClosePageButtonEventArgs = TryCast(e, ClosePageButtonEventArgs) TryCast(arg.Page, XtraTabPage).PageVisible = False End Sub

                                Please try it and let us know your results.

                                  I've created a separate ticket on your behalf (T814354: The hamburger menu buttons ignore the mouse cursor). It has been placed in our processing queue and will be answered shortly.
