This event is raised if the ImeMode property is changed by either a programmatic modification or through interaction.
For more information about handling events, see Consuming Events.
Example
[Visual Basic, C#, C++] The example below is an event handling method that is executed when the Text property value changes. The Control class has several methods with the name pattern PropertyName Changed that are raised when the corresponding PropertyName value changes(PropertyName represents the name of the corresponding property).
[Visual Basic, C#, C++] The following example changes the ForeColor of a TextBox displaying currency data. The example converts the text to a decimal number and changes the ForeColor to Color.Red if the number is negative and to Color.Black if the number is positive. This example assumes you have a Form that contains a TextBox.
[Visual Basic] Private Sub currencyTextBox_TextChanged(sender As Object, _ e As EventArgs) Handles currencyTextBox.TextChanged Try ' Convert the text to a Double and determine if it is a negative number. If Double.Parse(currencyTextBox.Text) < 0 Then ' If the number is negative, display it in Red. currencyTextBox.ForeColor = Color.Red Else ' If the number is not negative, display it in Black. currencyTextBox.ForeColor = Color.Black End If Catch ' If there is an error, display the text using the system colors. currencyTextBox.ForeColor = SystemColors.ControlText End Try End Sub [C#] private void currencyTextBox_TextChanged(object sender, EventArgs e) { try { // Convert the text to a Double and determine if it is a negative number. if(double.Parse(currencyTextBox.Text) < 0) { // If the number is negative, display it in Red. currencyTextBox.ForeColor = Color.Red; } else { // If the number is not negative, display it in Black. currencyTextBox.ForeColor = Color.Black; } } catch { // If there is an error, display the text using the system colors. currencyTextBox.ForeColor = SystemColors.ControlText; } } [C++] private: void currencyTextBox_TextChanged(Object* /*sender*/, EventArgs* /*e*/) { try { // Convert the text to a Double and determine if it is a negative number. if (Double::Parse(currencyTextBox->Text) < 0) { // If the number is negative, display it in Red. currencyTextBox->ForeColor = Color::Red; } else { // If the number is not negative, display it in Black. currencyTextBox->ForeColor = Color::Black; } } catch (Exception*) { // If there is an error, display the text using the system colors. currencyTextBox->ForeColor = SystemColors::ControlText; } }
