Form.InputLanguageChanged Event


Occurs after the input language of the form has changed.

 event System::Windows::Forms::InputLanguageChangedEventHandler ^ InputLanguageChanged;
public event System.Windows.Forms.InputLanguageChangedEventHandler InputLanguageChanged;
public event System.Windows.Forms.InputLanguageChangedEventHandler? InputLanguageChanged;
member this.InputLanguageChanged : System.Windows.Forms.InputLanguageChangedEventHandler 
Public Custom Event InputLanguageChanged As InputLanguageChangedEventHandler 

Event Type



The following example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the InputLanguageChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type Form named Form1. Then ensure that the event handler is associated with the InputLanguageChanged event.

private void Form1_InputLanguageChanged(Object sender, InputLanguageChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "InputLanguage", e.InputLanguage );
messageBoxCS.AppendFormat("{0} = {1}", "Culture", e.Culture );
messageBoxCS.AppendFormat("{0} = {1}", "CharSet", e.CharSet );
MessageBox.Show(messageBoxCS.ToString(), "InputLanguageChanged Event" );
Private Sub Form1_InputLanguageChanged(sender as Object, e as InputLanguageChangedEventArgs) _ 
     Handles Form1.InputLanguageChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "InputLanguage", e.InputLanguage)
    messageBoxVB.AppendFormat("{0} = {1}", "Culture", e.Culture)
    messageBoxVB.AppendFormat("{0} = {1}", "CharSet", e.CharSet)
    MessageBox.Show(messageBoxVB.ToString(),"InputLanguageChanged Event")

End Sub


You can use this event to make changes to your form's appearance and text based on changes made to the input language of the form.
