Calling an control event

[pvbangera]

Hi ppl

I want to call an control event from my procedure or function.

Say, I want to call a click event of CommandButton1. In VB6, it was very easy as there were no arguments to pass.

But how to do it in VB.Net? Mean, how to pass the 'sender' and 'e' argument while calling the event?

Pls guide

Regards,

Prakash

Investigate Raise Events, if I am correct then the event hasn't necessarily occured through the keyboard but you still want to act as if it has.

Not a solution but a response based on your posting.

Then do:

Private Sub SomeProcedure()
'Fire off the click event of CommandButton1
CommandButton1.PerformClick()
End Sub

PerfromClick is there. But that can be used only for Click event.

But what about other events?

Just declare the arguments and call the event passing the args.

Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDown
    Dim s As System.Object
    Dim ev As System.EventArgs
 
    Button1_MouseEnter(s, ev)
 
End Sub
 
Private Sub Button1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.MouseEnter
    MessageBox.Show("button1 mouse enter")
End Sub

You don't have to declare anything , like this :

Button1_Click(sender, e)

or

Button1_Click(Me, e)

Yes sender is generally the item that raised the event (in this cause the button) and you can pass Nothing or EventArgs.Empty if you don't need that parameter.
