How to Change MDI Tab Size in WinForms TabbedMDI

18 Nov 20181 minute to read

You should handle the TabControlAdded event handler and use the ItemSize property to change the tab size.

C#

// Handle the TabControlAdded event. 

this.tabbedMDIManager.TabControlAdded += new TabbedMDITabControlEventHandler(tabbedMDIManager_TabControlAdded); 

private void tabbedMDIManager_TabControlAdded(object sender, TabbedMDITabControlEventArgs args) 

{ 

// To change the size. 

args.TabControl.ItemSize = new Size(40, 40); 

}

VB.NET

' Handle the TabControlAdded event. 

AddHandler tabbedMDIManager.TabControlAdded, AddressOf tabbedMDIManager_TabControlAdded

Private Sub tabbedMDIManager_TabControlAdded(ByVal sender As Object, ByVal args As TabbedMDITabControlEventArgs)

' To change the size. 

args.TabControl.ItemSize = New Size(40, 40)

End Sub
