# How to: Bind to an ADO.NET Data Source
|
|
|
|
This example shows how to bind a Windows Presentation Foundation (WPF) <xref:System.Windows.Controls.ListBox> control to an ADO.NET `DataSet`.
|
|
|
|
## Example
|
|
|
|
In this example, an `OleDbConnection` object is used to connect to the data source which is an `Access MDB` file that is specified in the connection string. After the connection is established, an `OleDbDataAdapter` object is created. The `OleDbDataAdapter` object executes a select Structured Query Language (SQL) statement to retrieve the recordset from the database. The results from the SQL command are stored in a `DataTable` of the `DataSet` by calling the `Fill` method of the `OleDbDataAdapter`. The `DataTable` in this example is named `BookTable`. The example then sets the <xref:System.Windows.FrameworkElement.DataContext%2A> property of the <xref:System.Windows.Controls.ListBox> to the `DataSet` object.
|
|
|
|
[!code-csharp[ADODataSet#1](~/samples/snippets/csharp/VS_Snippets_Wpf/ADODataSet/CSharp/Window1.xaml.cs#1)]
|
|
[!code-vb[ADODataSet#1](~/samples/snippets/visualbasic/VS_Snippets_Wpf/ADODataSet/VisualBasic/Window1.xaml.vb#1)]
|
|
|
|
We can then bind the <xref:System.Windows.Controls.ItemsControl.ItemsSource%2A> property of the <xref:System.Windows.Controls.ListBox> to `BookTable` of the `DataSet`:
|
|
|
|
[!code-xaml[ADODataSet#2](~/samples/snippets/csharp/VS_Snippets_Wpf/ADODataSet/CSharp/Window1.xaml#2)]
|
|
|
|
`BookItemTemplate` is the <xref:System.Windows.DataTemplate> that defines how the data appears:
|
|
|
|
[!code-xaml[ADODataSet#3](~/samples/snippets/csharp/VS_Snippets_Wpf/ADODataSet/CSharp/Window1.xaml#3)]
|
|
|
|
The `IntColorConverter` converts an `int` to a color. With the use of this converter, the <xref:System.Windows.Controls.TextBlock.Background%2A> color of the third <xref:System.Windows.Controls.TextBlock> appears green if the value of `NumPages` is less than 350 and red otherwise. The implementation of the converter is not shown here.
