Ado .Net DataSet and WPF

If an element uses a binding expression and its DataContext property is null the element continues its search up the element tree. This search continues until the element finds a data object or reaches the toplevel container, which is the user control that represents the page.


DataSet is an offline disconnected data store. A DataSet can be constructed using the Fill method of SqlDataAdapter.

using System.Data;
using System.Data.SqlClient;


SqlConnection cnn;
SqlDataAdapter da;
DataSet ds = new DataSet();
private void Window_Loaded(object sender, RoutedEventArgs e)
{
    cnn = new SqlConnection(@"Data Source=.\sqlexpress;Integrated Security=sspi;Initial catalog=AirLines");
    da = new SqlDataAdapter("select * from Location", cnn);
    da.Fill(ds, "Loc");
    LayoutRoot.DataContext = ds.Tables["Loc"];
}

<Grid Name="LayoutRoot">
<ListBox ItemsSource="{Binding}"
            DisplayMemberPath="LocationName"
            Height="100" HorizontalAlignment="Left" Margin="10,10,0,0" Name="listBox1" VerticalAlignment="Top" Width="120" />
</Grid>

Binding to DataGrid

<Grid   Name="LayoutRoot">
    <DataGrid ItemsSource="{Binding}" AutoGenerateColumns="True" Height="150" HorizontalAlignment="Left" Margin="17,13,0,0" Name="dataGrid1" VerticalAlignment="Top" Width="325" />
</Grid>

WPF DataGrid Custom Columns

<Grid   Name="LayoutRoot">
<DataGrid ItemsSource="{Binding}" AutoGenerateColumns="False"  HorizontalAlignment="Left" Margin="42,12,0,0" Name="dataGrid1" Width="296">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Serial No" Binding="{Binding LocationId}" />
        <DataGridTextColumn Header="Location Name" Binding="{Binding LocationName}" />
        <DataGridTextColumn Header="Latitude" Binding="{Binding Latitude}" />
        <DataGridTextColumn Header="Longitude" Binding="{Binding Longitude}" />
    </DataGrid.Columns>
</DataGrid>
</Grid>

{Binding LocationName} is the shorthand to {Binding Path=LocationName}
