Concept of Create Menu Items in WPF C#

Introduction

In XAML and the WPF model, when we simply want a File menu like Visual Studio's that has New, Open, Close, Exit, and a few other standard shortcuts, the Menu and the Menu Item classes represent a menu and a menu item respectively. A Menu is a collection of menu items with a command associated with each item. Child menu items are called sub menus. This article discusses how to work with menus in XAML and WPF applications.

Creating a Menu as Design Time:
<Window x:Class="Create_Menu.MainWindow"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      Title="MainWindow" Height="371" Width="606">
     <Grid>
         <Menu>
             <MenuItem Header="File">            
                 <MenuItem Header="New" />              
                 <MenuItem Header="Open" IsCheckable="True" Click="Open_Click" />              
                 <MenuItem Header="Save" Click="Save_Click"/>
                 <MenuItem Header="Close"></MenuItem>
                 <Separator/>
                 <MenuItem Header="Recent File">
                  <MenuItem Header="ajay.docx"></MenuItem>
                  <MenuItem Header="Raj.txt"></MenuItem>
                 </MenuItem>
                 <Separator/>
                 <MenuItem Header="Exit" Click="Exit_Click"/>
             </MenuItem>           
             <MenuItem Header="Font">
                 <MenuItem.ToolTip>
                     <ToolTip>
                         Open a font menu.
                     </ToolTip>
                 </MenuItem.ToolTip>
                 <MenuItem Header="Bold" IsCheckable="True" Checked="Bold_Checked" Unchecked="Bold_Unchecked"/>
                 <MenuItem Header="Italic" IsCheckable="True"  Checked="Italic_Checked"  Unchecked="Italic_Unchecked"/>
                 <MenuItem Header="Thin" IsCheckable="True" Checked="Thin_Checked"/>
                 <MenuItem Header="Medium" IsCheckable="True" Checked="Medium_Checked"/>
                 <MenuItem Header="Increase Font Size" Click="IncreaseFont_Click"/>
                 <MenuItem Header="Decrease Font Size" Click="DecreaseFont_Click"/>
             </MenuItem>
         </Menu> 
         <Label Content="Welcome to MCN Solution" Height="28" HorizontalAlignment="Left" Margin="184,143,0,140" Name="lblmsg" />
     </Grid>
 </Window>



private void Open_Click(object sender, RoutedEventArgs e)
         {
             Microsoft.Win32.OpenFileDialog dl1 = new Microsoft.Win32.OpenFileDialog();
             dl1.FileName = "MYFileSave";
             dl1.DefaultExt = ".txt";
             dl1.Filter = "Text documents (.txt)|*.txt";
             Nullable<bool> result = dl1.ShowDialog();
             if (result == true)
             {
                 string filename = dl1.FileName;
             } 
         }
         private void Save_Click(object sender, RoutedEventArgs e)
         {
             Microsoft.Win32.SaveFileDialog dl1 = new Microsoft.Win32.SaveFileDialog(); 
             dl1.FileName = "MYFileSave";
             dl1.DefaultExt = ".txt";
             dl1.Filter = "Text documents (.txt)|*.txt";
             Nullable<bool> result = dl1.ShowDialog();
             if (result == true)
             {
                 string filename = dl1.FileName;
             }
         }
         private void Exit_Click(object sender, RoutedEventArgs e)
         {
             Close();
         }
         private void Bold_Checked(object sender, RoutedEventArgs e)
         {
             lblmsg.FontWeight = FontWeights.Bold;
         }
         private void Bold_Unchecked(object sender, RoutedEventArgs e)
         {
             lblmsg.FontWeight = FontWeights.Normal;
         } 
         private void Italic_Checked(object sender, RoutedEventArgs e)
         {
             lblmsg.FontStyle = FontStyles.Italic; 
         }
         private void Italic_Unchecked(object sender, RoutedEventArgs e)
         {
             lblmsg.FontStyle = FontStyles.Normal;
         } 
         private void IncreaseFont_Click(object sender, RoutedEventArgs e)
         {
             if (lblmsg.FontSize < 20)
             {
                 lblmsg.FontSize += 2;
             }
         }
          private void DecreaseFont_Click(object sender, RoutedEventArgs e)
         {
             if (lblmsg.FontSize > 10)
             {
                 lblmsg.FontSize -= 2;
             }
         } 
         private void Thin_Checked(object sender, RoutedEventArgs e)
         {
             lblmsg.FontWeight = FontWeights.Thin;
         } 
         private void Medium_Checked(object sender, RoutedEventArgs e)
         {
             lblmsg.FontWeight = FontWeights.Medium;
         }

OUTPUT



So when we click on open, the output will be:



So when will click on save, the output will be:



The output with the tooltip looks like:



Here we used a checked event in some places, so the output will be like this:
