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
