Attach commands to events. Inherits from EventToCommandBehavior The EventToCommandBehavior lets you link a command to an event in your UI. For example, the Text Editor control has a TextChanged event. With this behavior, you can trigger a command whenever that event occurs—like showing a toast notification every time the text is modified. Examples <Rock:FieldContainer> <Rock:TextEditor> <Rock:TextEditor.Behaviors> <Rock:EventToCommandBehavior EventName="TextChanged" Command="{Binding ShowToast}" CommandParameter="The text has been changed." /> </Rock:TextEditor.Behaviors> </Rock:TextEditor > </Rock:FieldContainer>
