Click a button programmatically

I want to code a button that programmatically clicks the other button when I click it.

For example, I have two buttons named Button1 and Button2, what I wanted to do is that immediately after I click Button1, it should click Button2. Is this possible?

Best implementation depends of what you are attempting to do exactly. Nadeem_MK gives you a valid one. Know you can also:

  1. raise the Button2_Click event using PerformClick() method:

    Private Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click
    'do stuff
    Me.Button2.PerformClick()
End Sub

  2. attach the same handler to many buttons:

    Private Sub Button1_Click(sender As Object, e As System.EventArgs) _
    Handles Button1.Click, Button2.Click
    'do stuff
End Sub

  3. call the Button2_Click method using the same arguments than Button1_Click(...) method (IF you need to know which is the sender, for example) :

    Private Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click
    'do stuff
     Button2_Click(sender, e)
End Sub

in c# this is working :D 

protect void button1_Click(object sender, EventArgs e){
    button2_Click(button2, null);
}

protect void button2_Click(object sender, EventeArgs e){
    //some codes here
}

for vb.net

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)   Handles Button1.Click
    Button2_Click(Sender, e)
End Sub

Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs)   Handles Button2.Click
    //some codes here
End Sub

The best practice for this sort of situation is to create a method that hold all the logics, and call the method in both events, rather than calling an event from another event;

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        LogicMethod()

End Sub

Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        LogicMethod()

End Sub

Private Sub LogicMethod()

     // All your logic goes here

End Sub

In case you need the properties of the EventArgs (e), you can easily pass it through parameters in your method, that will avoid errors if ever the sender is of different types. But that won't be a problem in your case, as both senders are of type Button.

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Button2_Click(Sender, e)
End Sub

Let say button 1 has an event called 

Button1_Click(Sender, eventarg)

If you want to call it in Button2 then call this function directly.

Button1_Click(Nothing, Nothing)
