Introduction

Here in this article we are discussing that how to use StatusBar in WPF. We have taken a CheckBox, Label and StatusBar control, when we checked the CheckBox. StatusBar will display in active and running state, when unchecked it will be in inactive and stopped state.

Getting Started

  • Simply create a new WPF application.
  • Drag a Grid, StatusBar, CheckBox and Label control on your MainWindow. Your window will look like below.

    <Window x:Class="MainWindow"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="271" Width
    ="327">
        <Grid>
            <StatusBar Height="30" Name="Stbr" VerticalAlignment="Bottom">
                <StatusBarItem>
                    <Label Name="labelStbr" Content="InActive" />
                </StatusBarItem>
                <StatusBarItem HorizontalAlignment="Right" >
                    <Label Name="labelRunning" Content="Stopped" />
                </StatusBarItem>
            </StatusBar>
            <CheckBox Height="16" HorizontalAlignment="Left" Margin="10,10,0,0"Name="checkOnOff"
    VerticalAlignment="Top" Width="120" Content="state" ToolTip="Click to activate">
                <CheckBox.Triggers>
                    <EventTrigger RoutedEvent="CheckBox.Checked">
                        <EventTrigger.Actions>
                            <BeginStoryboard>
                                <Storyboard>
                                    <StringAnimationUsingKeyFrames Storyboard.TargetName="labelStbr"
    Storyboard.TargetProperty="Content">
                                        <StringAnimationUsingKeyFrames.KeyFrames>
                                            <DiscreteStringKeyFrame Value="Active" KeyTime="0:0:0" />
                                        </StringAnimationUsingKeyFrames.KeyFrames>
                                    </StringAnimationUsingKeyFrames>
                                    <StringAnimationUsingKeyFrames
                                        Storyboard.TargetName="labelRunning"
                                        Storyboard.TargetProperty
    ="Content">

                    <EventTrigger RoutedEvent="CheckBox.Unchecked">
                        <EventTrigger.Actions>
                            <BeginStoryboard>
                                <Storyboard>

                                        </StringAnimationUsingKeyFrames.KeyFrames>
                                    </StringAnimationUsingKeyFrames>
                                    <StringAnimationUsingKeyFrames
                                        Storyboard.TargetName="labelRunning"
                                        Storyboard.TargetProperty
    ="Content">
                                        <StringAnimationUsingKeyFrames.KeyFrames>
