# Binding to DataReader

To extract values from a data source using a **DataReader,** use the GridViewTemplate **LoadFrom()** method to consume an object instance that supports `IDataReader`. The code sample below uses a `OleDbDataReader` reading an `Access` data source:

```C#
OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=..\\..\\DataSources\\Nwind.mdb");
conn.Open();
OleDbCommand cmd = new OleDbCommand("Select TOP 5 * FROM Customers", conn);
OleDbDataReader reader = cmd.ExecuteReader();
radGridView1.MasterTemplate.LoadFrom(reader);
```

```VB.NET
Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=..\\..\\DataSources\\Nwind.mdb")
conn.Open()
Dim cmd As New OleDbCommand("Select TOP 5 * FROM Customers", conn)
Dim reader As OleDbDataReader = cmd.ExecuteReader()
RadGridView1.MasterTemplate.LoadFrom(reader)
```
