In this article, we’ll dive into one of the core building blocks of WPF — XAML. We’ll explore how it works and why it plays such an important role in building modern desktop applications. What is XAML? XAML stands for eXtensible Application Markup Language. It’s a markup language used to design the user interface in WPF applications. XAML allows developers and designers to work separately, making the code cleaner and easier to manage. Think of it as HTML for WPF apps. XAML Syntax XAML uses XML-style syntax. Every UI element is an XML tag. Attributes define properties like height, width, and content. You can also nest elements inside others to create more complex layouts. For example, placing a TextBlock inside a Grid layout. <Grid>     <TextBlock Text="Hello, WPF World!"                 Width="200"                 Height="50"              ...

How to show xml data in DataGrid?

XMLData.xml

<Students>
  <Student>
    <Roll>1</Roll>
    <Name>Kumar</Name>
  </Student>
  <Student>
    <Roll>2</Roll>
    <Name>Harsh</Name>
  </Student>
</Students>

Create a class for xml data
public partial class Student
    {

        public int Roll { getset; }
      
        
        public string Name { getset; }
    }
Code To get data from xml file
XmlSerializer serializer = new XmlSerializer(typeof(ObservableCollection<Student>)newXmlRootAttribute("Students"));//here Student is type and Students is root of xml
         
            using (StreamReader reader = newStreamReader(@"D:\XMLData.xml"))
            {
                //Deserilize the xml file and assign to collection
                LstStudents =(ObservableCollection<Student>)serializer.Deserialize(reader);
            };
private ObservableCollection<Student> _lstStudents=new ObservableCollection<Student>();

        public ObservableCollection<Student> LstStudents
        {
            get { return _lstStudents; }
            set {SetProperty(ref _lstStudents , value); }
        }

Bind LstStudents to DataGrid
<DataGrid ItemsSource="{Binding LstStudents}"Width="200" AutoGenerateColumns="False">
                <DataGrid.Columns>
                    <DataGridTextColumn Header="Roll"Binding="{Binding Roll}"  />
                    <DataGridTextColumn Header="Name"Binding="{Binding Name}"  />
                </DataGrid.Columns>
              
            </DataGrid>
