Event needs WithEvents?

Question

Event needs WithEvents?

Connor Frayne 35

Hello,

I have this in Form1,

Public Event BTN_PROF_Details_Event()
Private Sub FID_Container_Click(sender As Object, e As EventArgs) Handles BTN_PROF_Details.Click
    RaiseEvent BTN_PROF_Details_Event()
End Sub

Then this is in an Object class

Private Sub PNL_PROF_FID_Event(ByVal sender As Object, ByVal e As EventArgs) Handles BTN_PROF_Details_Event
        Trace.WriteLine("test")
End Sub

My problem stems from the event requiring WithEvents?

How could I fix this?

Thank you,

Connor Frayne

Hi @Connor Frayne ,

When a variable is defined using WithEvents, you can declaratively specify that a method handles the variable's events using the Handles keyword.

You can use WithEvents only at class or module level. This means the declaration context for a WithEvents variable must be a class or module and cannot be a source file, namespace, structure, or procedure.

So if you want to Handle Event, you have to declare the event with WithEvents in class.

This should work in your class:

Public WithEvents f1 As Form1

Private Sub PNL_PROF_FID_Event() Handles f1.BTN_PROF_Details_Event
   Trace.WriteLine("test")
End Sub

The Form1 form must be assigned to f1. (You can use Me if the object is created inside the Form1).
