SpellCheck Features of WPF textbox

Take a look at the MSDN example for the best:

Http://msdn.microsoft.com/zh-cn/library/vstudio/system.windows.controls.primitives.textboxbase.spellcheck (v= vs.100). aspx

Give an example a comment:

        Public MainWindow () {InitializeComponent (); Mytextbox.contextmenu = Getcontextmenu ();//Initialize Right-click menu (Context menu)} void Tb_contextmenuopening (object
            sender, RoutedEventArgs e) {int caretindex, cmdindex;

            Spellingerror Spellingerror; Mytextbox.contextmenu = Getcontextmenu ();//get default Menu Caretindex = mytextbox.caretindex;//cursor position Cmdind ex = 0;//menu item Ordinal spellingerror = Mytextbox.getspellingerror (Caretindex);//Gets the current cursor error, or null if there is no spelling error F (spellingerror! = null) {//correct spelling of each recommended spelling error, create a menu item foreach (String str in
                    spellingerror.suggestions) {MenuItem mi = new MenuItem (); Mi. Header = The text content of the str;//menu item mi.
                    FontWeight = Fontweights.bold;
Mi.command = editingcommands.correctspellingerror;//menu item Clicking on the executed command is a command that changes the spelling error at the current cursor.                    Mi. CommandParameter = str;//The parameter of this command mi. Commandtarget = mytextbox;//This command executes the target text box MyTextBox.ContextMenu.Items.Insert (Cmdindex, MI);//Add the item to the right-click menu Ordinal position cmdindex++;//sequence number increment} Separator separatorMenuItem1 = new Separator (
                );
                MyTextBox.ContextMenu.Items.Insert (Cmdindex, separatorMenuItem1);//Insert a split horizontal line cmdindex++;
                MenuItem Ignoreallmi = new MenuItem ();//Create a new menu item that ignores all spelling errors Ignoreallmi.header = "Ignore all";
                Ignoreallmi.command = Editingcommands.ignorespellingerror;
                Ignoreallmi.commandtarget = MyTextBox;
                MyTextBox.ContextMenu.Items.Insert (Cmdindex, Ignoreallmi);
                cmdindex++;
                Separator separatorMenuItem2 = new Separator ();
            MyTextBox.ContextMenu.Items.Insert (Cmdindex, separatorMenuItem2);//Insert a split line, followed by the default menu item.

 }
        }       Private ContextMenu Getcontextmenu () {ContextMenu cm = new ContextMenu ();
            Can Create STATIC custom menu items if exists here ...
            MenuItem M1, M2, M3, M4;
            M1 = new MenuItem (); M1.
            Header = "File";//m1.command = Applicationcommands.save;
            m2 = new MenuItem (); M2.
            Header = "Save";
            M3 = new MenuItem (); M3.
            Header = "SaveAs";
            M4 = new MenuItem (); M4.

            Header = "recent Files"; Can add functionality for the custom menu items here ... cm.
            Items.Add (M1); Cm.
            Items.Add (m2); Cm.
            Items.Add (m3); Cm.

            Items.Add (M4);
        return cm; }

The user dictionary can be defined in the SpellCheck customdictionaries, and the spelling checker ignores these words.

Then we study the Spellingerror class to see if we can play any tricks.
