OnValueChanged Method

Fires ValueChanged event. This method gets called whenever the value in the control changes.

Syntax

'Declaration
 
Protected Overridable Sub OnValueChanged( _
   ByVal e As EventArgs _
)

   EventArgs e

Example

Following code prints out the value as it changes. Current value in the masked edit can be invalid. For example, in the case of a date, if the input hasn't been fully entered then a DateTime object can not be constructed. To find out if the masked edit has a valid value entered, following code uses IsFullyInput property. If the input is invalid, it prints out the text in the masked edit.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.

      ' ValueChanged gets fired whenever value inside the masked edit changes.
      ' Following code prints out the current value in the masked edit. If the value
      ' is invalid, then it prints out the text.

      If Me.UltraMaskedEdit1.IsFullyInput Then
