I wrote the code in C#.
I was writing a simple example of clicking the button to add the values in the two text boxes.
- MainWindow.xaml.cs
namespace bhwpftest
{
public partial class MainWindow : Window
{
**Calc calc = new Calc();**
public MainWindow()
{
InitializeComponent();
**panel.DataContext = calc;**
}
1-1. MainWindow.xaml
<TextBox Grid.Column="0" Text="{Binding **Value1**}"></TextBox>
<TextBox Grid.Column="1" Text="{Binding **Value2**}"></TextBox>
<TextBlock Grid.Column="3" Text="{Binding **Result**}" ></TextBlock>
and
- MainWindow.xaml.cs
//Calc calc = new Calc(); //dosen't work
**public Calc calc { get; set; } = new Calc();**
...
public MainWindow()
{
InitializeComponent();
//panel.DataContext = calc;
}
2-1. MainWindow.xaml
<Window x:Class="bhwpftest.MainWindow"
.
.
.
**DataContext="{Binding RelativeSource={RelativeSource Self}}"**
>
<TextBox Grid.Column="0" Text="{Binding **calc.Value1**}"></TextBox>
<TextBox Grid.Column="1" Text="{Binding **calc.Value2**}"></TextBox>
<TextBlock Grid.Column="3" Text="{Binding **calc.Result**}" ></TextBlock>
</Window>
I think it is same working
I want to know why there is such a difference and what the difference is.
Thank you.
