As there is no easy way that I know of (then again I'm a WinForms newbie) to close the selected tab, I'd like to set up an event handler for handling a right click through which the tab will close. In simple words I want to right-click on the selected tab in order to close it. This is the event handler which I have written (yet doesn't work): private void tab_Click(object sender, EventArgs e) {

问题 I am trying to create a browser-style TabControl with a small close button on every tab in FireMonkey FM2. Since there are no TTabsheet and TPageControl components in FM2, I could not use the answer from "How to implement a close button for a TTabsheet of a TPageControl".

Searching on the net, I found

问题 Hi All! I have a trouble with xaml-markup design that is shown on a picture. How to place window buttons in one line with tab item headers TAB1 , TAB2 , TAB3 ?

问题 I have found multiple questions about this problem on SO, however I still can't quite get a realiable solution. Here is what I came up with after reading the answers. Xaml: <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="300" Width="300" x:Name="this"> <TabControl IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding Tabs, ElementName=this}" x

问题 I currently have a Form with a TabControl containing some TabPage s. Each TabPage has several controls with validation logic and appropriate ErrorProvider s. On my OK_Button_Clicked event, I call Form.ValidateChildren() in order to determine whether to save and close the form .
