Examples

<asp:EntityDataSource ID="ProductDataSource" runat="server"
    CommandText="SELECT value p FROM Products AS p
        WHERE p.ProductID
        BETWEEN @OrderIdMin AND @OrderIdMax"
    ConnectionString="name=AdventureWorksEntities"
    DefaultContainerName="AdventureWorksEntities" >
    <CommandParameters>
        <asp:ControlParameter Name="OrderIdMin"
            ControlID="ProductIdMin" Type="Int32"/>
        <asp:ControlParameter Name="OrderIdMax"
            ControlID="ProductIdMax" Type="Int32" />
    </CommandParameters>
</asp:EntityDataSource>

The following example returns a projected series of columns:

<asp:EntityDataSource ID="ProductDataSource" runat="server"
    CommandText="SELECT p.ProductID, p.ProductName, p.UnitsOnOrder
         FROM Products AS p
         WHERE p.ProductID BETWEEN @OrderIDMin AND @OrderIDMax"
         ContextTypeName="AdventureWorksModel. AdventureWorksEntities">
    <CommandParameters>
        <asp:ControlParameter Name="OrderIDMin"
               ControlID="ProductIDMinTextBox" Type="Int32"/>
        <asp:ControlParameter Name="OrderIDMax"
               ControlID="ProductIDMaxTextBox" Type="Int32" />
    </CommandParameters>
</asp:EntityDataSource>
