Have you ever noticed that the MouseLeftButtonDown and MouseLeftButtonUp events are not fired when a Silverlight button is clicked? The reason for this is that the button handles these two events itself by overriding the OnMouseLeftButtonDown  and the OnMouseLeftButtonUp  handlers. In the OnMouseLeftButtonDown  override, the Click event is raised and the MouseLeftButtonDown event is marked as handled so it couldn't bubble in the visual tree. The OnMouseLeftButtonUp  override also marks the MouseLeftButtonUp  as handled.

This thing can be changed using the ClickMode property of the Button control. It has the following values - Hover, Press, Release. The default one is Pressed and we have already explained it. When we have ClickMode set to Release, the Click event will be raised in the OnMouseLeftButtonUp override and the MouseLeftButtonDown and MouseLeftButtonUp events will be handled inside the button again. If we set the ClickMode to Hover, the Click event will be raised with the MouseEnter event and we will also be able to use the mouse button events.

That's it!

In Silverlight the Button, as some other controls does not have the old well known Text property. It is replaced by a new property named Content of type object. The idea is to remove the limitation to show only strings as content of a control. Now with this new approach you can put whatever you wish inside of a Button. This makes the presentation layer extremely powerful. However if you provide a regular string for the Content then the result will be exactly as if we used the Text property.

Xaml

<Button x:Name="simpleButton" Content="Click Me" />

<Button x:Name="advancedButton">

    <Button.Content>

        <CheckBox Content="Check box on a button"></CheckBox>

    </Button.Content>

</Button>

C#

Button simpleButton = new Button();

simpleButton.Content = "Click Me";

Button advancedButton = new Button();

CheckBox checkBox = new CheckBox();

checkBox.Content = "Check box on a button";

advancedButton.Content = checkBox;

As you can see the first button named simpleButton uses plain text 'Click Me' for its content, while the second button named advancedButton hosts check box control with the text 'Check box on a button'.

That's it!
