Source Property (DataGridCollectionViewSourceBase)

Visual Basic
C#

'Declaration
 
Public Shadows Property Source As Object

'Usage
 
Dim instance As DataGridCollectionViewSourceBase

Dim value As Object

 

instance.Source = value

 

value = instance.Source

public new object Source {get; set;}

Property Value

An object representing the collection from which the view is created. By default, a null reference (Nothing in Visual Basic).

All examples in this topic assume that the grid is bound to the Orders table of the Northwind database, unless stated otherwise.

This first code example demonstrates how to create a connection to the Access version of the Northwind database and create a property named Orders to which the grid will be bound. The code should be placed in the App.xaml.vb file.

Visual Basic

Imports System.Data.OleDb

Imports System.Data

Shared Sub New()

  Dim dataSet As New DataSet()

  Dim mdbfile As String = "Data\Northwind.mdb"

  Dim connString As String = String.Format("Provider=Microsoft.Jet.OLEDB.4.0; Data Source={0}", mdbfile)

  Dim conn As New OleDbConnection(connString)

  Dim adapter As New OleDbDataAdapter()



  adapter.SelectCommand = New OleDbCommand("SELECT * FROM Orders;", conn)

  adapter.Fill(dataSet, "Orders")

  m_orders = dataSet.Tables("Orders")

End Sub



Public Shared Readonly Property Orders() As DataTable

  Get

    Return m_orders

  End Get

End Property

Private Shared m_orders As DataTable

This first code example demonstrates how to create a connection to the Access version of the Northwind database and create a property named Orders to which the grid will be bound. The code should be placed in the App.xaml.cs file.

C#

using System.Data.OleDb;

using System.Data;



Static App()

{

  DataSet dataSet = New DataSet();

  string mdbFile = @"Data\Northwind.mdb";

  string connString = String.Format( "Provider=Microsoft.Jet.OLEDB.4.0; Data Source={0}", mdbFile );



  OleDbConnection conn = New OleDbConnection( connString );

  OleDbDataAdapter adapter = New OleDbDataAdapter();



  adapter.SelectCommand = New OleDbCommand( "SELECT * FROM Orders;", conn );

  adapter.Fill( dataSet, "Orders" );



  m_orders = dataSet.Tables[ "Orders" ];

}



public static DataTable Orders

{

  get

  {

     return m_orders;

  }

}



private static DataTable m_orders;

The next example demonstrates how to bind a grid to the Orders table, which is retrieved through the Orders property implemented in the code above.

XAML

<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid"> 

  <Grid.Resources>        

  <xcdg:DataGridCollectionViewSource x:Key="cvs_orders" 

                                  Source="{Binding Source={x:Static Application.Current}, 

                                                      Path=Orders}"/> 

  </Grid.Resources> 

  <xcdg:DataGridControl x:Name="OrdersGrid" 

                        ItemsSource="{Binding Source={StaticResource cvs_orders}}"/> 

</Grid>
