This is custom control that provides a way to alert users whether an operation was successfully completed or not. Why use MessageBox when you have the powerfull WPF in your hands?

Aren't you tired of all the MessageBoxes on your applications? Isn't there a better way to alert users whether an operation was successfully completed? For years I used MessageBox or a static label in WinForms applications, and they came with me when I started to migrate to WPF.

However, WPF is so much more powerfull than that, and I thought why not create something different? Because let's face it, using MessageBox is like using javascript alert function in a web page, don't you think?. So it is settle, we need something new, but what? Well, once I was a [Rails] (http://rubyonrails.org/) developer and Rails has a interesting [flash message system] (http://guides.rubyonrails.org/action_controller_overview.html#the-flash), so I thought of creating a control that acts slightly similar.

So, let's see how the control works. It has two mainly properties: MessageType and Message.

MessageType whether a Error, Success or Notice. These influence which style the control uses.

Message it's the message itself. As soon as this property is changed, the FlashMessage fades in automatically.

FadesOutAutomatically besides clicking on the close button, you can configure whether it fades out automatically.

FadeOutTime it specifies how much time the FlashMessage waits to fades out after it fades in;

Add a reference of FlashMessage.dll to your project.

Add the namespace to your Window:

xmlns:flash="clr-namespace:FlashMessage;assembly=FlashMessage"

Add the control wherever you like:

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="27"/>
    </Grid.RowDefinitions>

    <flash:FlashMessage Grid.Row="0" Grid.Column="0" Message="Successfully saved." MessageType="Success"/>

    <!--Others controls-->
</Grid>
