PanelContainerDesigner.Initialize Method (IComponent)

 

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

Namespace:   System.Web.UI.Design.WebControls
Assembly:  System.Design (in System.Design.dll)

Public Overrides Sub Initialize (
	component As IComponent
)

Parameters

component
Type: System.ComponentModel.IComponent

A Panel, which implements an IComponent.

Exception Condition
ArgumentException

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

The visual designer calls the Initialize method when it is ready to use the designer to render the Panel 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 Panel control that is associated with this designer or a copy of the Panel control.

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

' Initialize the designer.
Public Overrides Sub Initialize(ByVal component As IComponent)

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

    MyBase.Initialize(component)

End Sub ' Initialize
