Question

I have a simple class abc

class abc
        {
            public string a { get; set; }
            public string b { get; set; }
            public string c { get; set; }

            public abc(string d, string e, string f)
            {
                a = d;
                b = e;
                c = f;
            }
        }



public MainPage()
        {
            InitializeComponent();

            abc obj = new abc("abc1", "abc2", "abc3");
            LayoutRoot.DataContext = obj;


        }

and a grid which contain three textbox 1 2 3 I am trying to bind these 3 properties of a class to a grid usercontrol.

<Grid x:Name="LayoutRoot" Background="White">
        <TextBox Height="27" HorizontalAlignment="Left" Margin="125,86,0,0" Name="textBox1" Text="{Binding Path= a}" VerticalAlignment="Top" Width="120" />
        <TextBox Height="25" HorizontalAlignment="Left" Margin="21,192,0,83" Name="textBox2" Text="{Binding Path= b}"  Width="120" />
        <TextBox Height="25" HorizontalAlignment="Left" Margin="250,192,0,0" Name="textBox3" Text="{Binding Path= c}" VerticalAlignment="Top"  Width="120" />
    </Grid>

it doesn’t show any error but it does not show any output to a screen,what specific problem it creating?

Answer 1

Try do not use “Path= ” (with space) in the binding expression. Try use:

Text="{Binding a}"

“Path” is present hiddenly in binding expressions. You need read some resources about bindings.
