Working with WPF StatusBar using VB.NET

Introduction

Here I am sharing a small story in which 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.
  
  
  
  
• Your MainWindow.xaml page will look like below.
  
  <Window x:Class="MainWindow"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      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">
                                      <StringAnimationUsingKeyFrames.KeyFrames>
                                          <DiscreteStringKeyFrame Value="Running..." KeyTime="0:0:0" />
                                      </StringAnimationUsingKeyFrames.KeyFrames>
                                  </StringAnimationUsingKeyFrames>
                              </Storyboard>
                          </BeginStoryboard>
                      </EventTrigger.Actions>
                  </EventTrigger>
                  <EventTrigger RoutedEvent="CheckBox.Unchecked">
                      <EventTrigger.Actions>
                          <BeginStoryboard>
                              <Storyboard>
                                  <StringAnimationUsingKeyFrames
                                      Storyboard.TargetName="labelStbr"
                                      Storyboard.TargetProperty="Content">
                                      <StringAnimationUsingKeyFrames.KeyFrames>
                                          <DiscreteStringKeyFrame Value="InActive" KeyTime="0:0:0" />
                                      </StringAnimationUsingKeyFrames.KeyFrames>
                                  </StringAnimationUsingKeyFrames>
                                  <StringAnimationUsingKeyFrames
                                      Storyboard.TargetName="labelRunning"
                                      Storyboard.TargetProperty="Content">
                                      <StringAnimationUsingKeyFrames.KeyFrames>
                                          <DiscreteStringKeyFrame Value="Stopped" KeyTime="0:0:0" />
                                      </StringAnimationUsingKeyFrames.KeyFrames>
                                  </StringAnimationUsingKeyFrames>
                              </Storyboard>
                          </BeginStoryboard>
                      </EventTrigger.Actions>
                  </EventTrigger>
              </CheckBox.Triggers>
          </CheckBox>
      </Grid>
  </Window>
   
• Now run your application
