LoginViewDesigner.Initialize(IComponent) Method

  • Reference

Definition

Namespace:
System.Web.UI.Design.WebControls
Assembly:
System.Design.dll

Prepares the designer to view, edit, and design the associated control.

public:
 override void Initialize(System::ComponentModel::IComponent ^ component);
public override void Initialize (System.ComponentModel.IComponent component);
override this.Initialize : System.ComponentModel.IComponent -> unit
Public Overrides Sub Initialize (component As IComponent)

Parameters

component
IComponent

A LoginView, which implements an IComponent.

Exceptions

ArgumentException

component is not a LoginView or of a class derived from LoginView.

Examples

The following code example shows how to override the Initialize method in a class that is inherited from the LoginViewDesigner class to change the behavior of a control that is derived from the LoginView class at design time. The example throws an ArgumentException, if the associated control is not a MyLoginView object.

public override void Initialize(IComponent component)
{
    // Ensure that only a MyLoginView can be created in this designer.
    if (!(component is MyLoginView))
        throw new ArgumentException();

    // Call the base method to generate the markup.
    base.Initialize(component);
} // Initialize

' Generate the design time markup.
Public Overrides Sub Initialize(ByVal component As IComponent)

    ' Ensure that only a MyLoginView can be created in this designer. 
    If Not TypeOf component Is MyLoginView Then
        Throw New ArgumentException()
    End If

    ' Call the base method to generate the markup.
    MyBase.Initialize(component)

End Sub

Remarks

The visual designer calls the Initialize method when it is ready to use the designer to render the LoginView control. The Initialize and its base methods configure properties and set up events that are necessary for the operation of the designer.

The component parameter is the LoginView control that is associated with this designer or a copy of the LoginView control.
