Examples

The following code example demonstrates how to override the Construct method of a custom control that is derived from the TemplateControl class.

For the full definition of the MyControl class, see TemplateControl.

// Create an event for this user control
public event System.EventHandler myControl;

// Override the default constructor.
protected override void Construct()
{
    // Specify the handler for the OnInit method.
    this.myControl += new EventHandler(MyInit);
}

protected override void OnInit(EventArgs e)
{
    myControl(this, e);
    Response.Write("The OnInit() method is used to raise the Init event.");
}

// Use the MyInit handler to set the Message property
void MyInit(object sender, System.EventArgs e)
{
    Message = "Hello World!";
}

 ' Create an event for this user control
 Public Event myControl As System.EventHandler

 ' Override the default constructor.
 Protected Overrides Sub Construct()
     ' Specify the handler for the OnInit method.
     AddHandler Me.myControl, AddressOf MyInit
 End Sub

 Protected Overrides Sub OnInit(ByVal e As EventArgs)
     RaiseEvent myControl(Me, e)
     Response.Write("The OnInit() method is used to raise the Init event.")
 End Sub


 ' Use the MyInit handler to set the Message property
 Sub MyInit(ByVal sender As Object, ByVal e As System.EventArgs)
     Message = "Hello World!"
 End Sub

Remarks

The Construct method allows design-time code execution of the Page and UserControl controls.
