Hello, Asad,
I'm not sure that I understand the problem.
Why can't you just put the code of the inherited form's event handler
into a conditional block? I.e. something like:
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles Button1.Click
If (Appropriate...) Then
Do actions...
End If
End Sub
Is it actually the code of the event handler in the Base form that you
need to inhibit? In this case, I would either:
a) Define an overridable property to control when the Base form code is
executed. E.g. something like:
Protected Overridable ReadOnly _
Property SkipBaseButtonClick() As Boolean
Get
Return False
End Get
End Property
Then test this property in the Base form's handler:
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles Button1.Click
If (Not SkipBaseButtonClick) Then
Do actions...
End If
End Sub
Override the property in the inherited form and return either True or
False as appropriate.
or
b) Define a new event in the Base form that includes a "Cancel"
argument. E.g. something like:
Public Event BaseButtonClick(_
ByVal sender As System.Object, _
ByVal eCancel As System.ComponentModel.CancelEventArgs)
Raise this new event in the Base form handler and only execute the base
form code if the "cancel" property of eCancel is not returned as True.
Then in the inherited form Handle BaseButtonClick instead of Button1.Click.
But let me know if it is something else that you are looking for.
Cheers,
Randy

really need that there, then in the logic of that click event, you could
branch to the MyBase.Button1_Click() event instead of processing the
inherited form's code.

>>>hi to all
this is the problem about inheritence. I have designed a form with some
essential controls which are required for every form which will
inherited from it. for example i have Button1 on parent form and this
button is visible to me on inherited form.
The problem is:
I have written a click event of the button1 on both of the forms. tell
me the way if i click the button on inherited form only parents' click
event will be called and iherited form's evend wil not be called.
Plz guide me in this regard
Thans in advance
