Missing events in MyBase when using control inheritance

I have been programming in C# for the past few years and I'm now trying
to implement something in VB.NET (Framework 1.1) that I'm having a
problem with...

In C# I can create a new class and make it dervived from a Microsoft
Windows Forms control (e.g. TabControl), then in the constructor I can
add an event handler to the ControlAdded and ControlRemoved events like

public Class1()
// TODO: Add constructor logic here

this.ControlAdd ed += new ControlEventHan dler(Class1_Con trolAdded);
this.ControlRem oved += new
ControlEventHan dler(Class1_Con trolRemoved);


The ControlAdded and ControlRemoved events are protected events of the
base class TabControl, when attempting this Using VB.NET it fails, for
example. This:
Private Sub TabControl1_Con trolAdded(ByVal sender As System.Object, _
ByVal e As System.EventArg s) Handles MyBase.ControlA dded

End Sub

Creates a compile time error and Visual Studio.NET intellisense does
not show ControlAdded and ControlRemoved events as being available
events off of MyBase.

I would like to know if anyone can recommend a work around to this. I
really need to handle these two events in my dervived control.

'System.EventAr gs' => 'ControlEventAr gs'.

Hi I use the following syntax to have events inherited from base to child classes which works nicely (virtual and override keyword on events). But I am wondering if it is a "supported" way of using events since I never saw it used anywhere in MSDN documentation/samples?! Or it will just break when I upgrade to .NET Framework 2.x in the coming years namespace MyNamespac public delegate void MyDel() public class MyBase public virtual...

I have been working for quite some time on this issue which in theory should be quite simple. The problem is that the Cancel and Save events are not fired when their respective buttons are clicked. I have read several posts which say to put your column generating section in the Page_Init section and it will solve the problem....however, it hasn't solved mine. Can somebody please take a look at this and provide any insight if possible?

Is there any way to reliably catch KeyUp events for Function keys in particular while inside a datagrid? I have a form with KeyPreview=True and I am using the Form.KeyUp event to handle several function keys (F5, F6, etc.) The problem is I have a datagrid on this form and it seems whenever the datagrid has the focus, it consumes most of the key events without passing them on to me. I have tried using a DataGridTextBox control, which...

I have a control that inheirts from "Panel". I want to prevent the user from having access to the MoueUp event.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
