Handle master page button(s) click events on content page

[De_Novice]

I have a master page ( masterpage.master) that has 2 link buttons lnkbtn_save and lnkbtn_edit. I have 2 content pages ( product and customer). When the user is on customer.aspx and clicks the lnkbtn_edit I want the controls on the customer page to be enabled and when the user clicks lnkbtn_save, I want the customer data to be saved. Basically the linkbuttons click event needs to be handles in the content page. learning for the fist process in this video ()[^] I could create a click event for one link button. How would I do this for two buttons. Here is my code:-- masterpage.aspx.vb

Partial Class MasterPage
Inherits System.Web.UI.MasterPage
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

End Sub

Protected Sub lnkbtn\_save\_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButton1.Click

End Sub

Public ReadOnly Property Masterbtnsave() As LinkButton
    Get
        Return lnkbtn\_Save
    End Get

End Property

End Class

customer.aspx.vb

Partial Class customer
Inherits System.Web.UI.Page

Protected Sub Masterbtnsave\_Click(ByVal sender As Object, ByVal e As System.EventArgs)
    MsgBox("from customer page")
End Sub
Protected Sub Page\_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    AddHandler Me.Master.Masterbtnsave.click, AddressOf Masterbtnsave\_Click

End Sub

End Class

My question is: in the masterpage code behind I am returning the actual name of the lnkbutton in the property, how can I make this such that it returns the name of the button that was clicked. And then in the content page based on the button that was clicked some code is executed. Any help will be appreciated

There is also an abstract approach. I am new to classes and delegate events, kindlt explain in detail to a beginner.
