argument not specified for parameter 'eventArgs' - calling sub in another UserControl

If a UserControl contains a Sub such as

Public Sub BackOne_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles BackOne.Click

and another UserControl calls the Sub above as per;

MainForm.ctlPostEdit.BackOne_Click() where it is defined on the MainForm as;

Public ctlPostEdit As PostEdit.PostEdit,

why/how would I solve the following error

Argument not specified for parameter 'eventArgs' of 'Public Sub BackOne_Click(eventSender As Object, eventArgs As System.EventArgs)'

This worked just as is in the previous vb6 app.

Thank you,

Thank you Reed! the eventSender made sense but 'newing up eventargs wasn't obvious.

You have to provide the arguements specified in the method signiture (in this case, a System.Object and a System.EventArgs).

This can be done using:
MainForm.ctlPostEdit.BackOne_Click(Me, New System.EventArgs)

But you can also just call
MainForm.ctlPostEdit.BackOne.PerformClick()
