Examples

This section provides two code examples. The first demonstrates how to extend the AccessDataSourceDesigner class. The second demonstrates how to derive a copy of the AccessDataSource class and associate it with a designer.

The following code example demonstrates how to extend the AccessDataSourceDesigner class. The code alters the placeholder that represents the control on the design surface and adds a property to the Properties grid.

// Shadow control properties with design time properties.
protected override void PreFilterProperties(IDictionary properties)
{
    // Call the base class method first.
    base.PreFilterProperties(properties);

    // Add the ConnectionString property to the property grid.
    PropertyDescriptor property =
        (PropertyDescriptor)properties["ConnectionString"];
    Attribute[] attributes = new Attribute[]
    {
        new BrowsableAttribute(true),
        new ReadOnlyAttribute(true)
    };
    properties["ConnectionString"] = TypeDescriptor.CreateProperty(
        GetType(), property, attributes);
}

' Shadow control properties with design time properties.
Protected Overrides Sub PreFilterProperties(ByVal properties As IDictionary)

    ' Call the base class method first.
    MyBase.PreFilterProperties(properties)

    ' Add the ConnectionString property to the property grid.
    Dim prop As PropertyDescriptor
    prop = CType(properties("ConnectionString"), PropertyDescriptor)

   Dim atts(1) As Attribute
    atts(0) = New BrowsableAttribute(True)
    atts(1) = New ReadOnlyAttribute(True)

    properties("ConnectionString") = TypeDescriptor.CreateProperty( _
        prop.GetType(), prop, atts)
End Sub

The following code example demonstrates how to derive a copy of the AccessDataSource class and associate it with the designer that was defined in the preceding example.

// Create a control and bind it to the ExampleAccessDataSourceDesigner.
[AspNetHostingPermission(System.Security.Permissions.SecurityAction.Demand,
    Level = AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermission(System.Security.Permissions.SecurityAction.InheritanceDemand,
    Level = AspNetHostingPermissionLevel.Minimal)]
[Designer(typeof(CustomControls.Design.ExampleAccessDataSourceDesigner))]
public class ExampleAccessDataSource : AccessDataSource
{
    // Does nothing extra
}

' Create a control and bind it to the ExampleAccessDataSourceDesigner.
<AspNetHostingPermission(System.Security.Permissions.SecurityAction.Demand, _
    Level:=System.Web.AspNetHostingPermissionLevel.Minimal)> _
<AspNetHostingPermission(System.Security.Permissions.SecurityAction.InheritanceDemand, _
    Level:=System.Web.AspNetHostingPermissionLevel.Minimal)> _
<Designer("CustomControls.Design.ExampleAccessDataSourceDesigner")> _
Public Class ExampleAccessDataSource
    Inherits AccessDataSource

    ' Does nothing extra
End Class

Remarks

In a visual designer, when you switch from Source to Design view, the markup source code that describes the AccessDataSource control is parsed and a design-time version of the control, which is just a placeholder, is created on the design surface. When you switch back to Source view, the design-time control, which includes the values of the properties in the Properties grid, is persisted to the markup source code and edited into the markup for the Web page.
