SDK. C#. Individual Item events.

[Former Member]

public void CreateButton()
{
    Item button = ...
    // Create button
    ...
    ...
    ...
    ( button.Specific as Button ).ClickAfter += OnClick;
}
			
public void OnClick( object sboObject, SBOItemEventArg pVal )
{	
    // MessageBox
}

Hello. I have a question about individual item events. It is impossible to cause the event. The above code does not work. How can I rise this event (without inspection if(form && button && event_type) ). Thanks.

Hi Roman,

This boils back to the scope of your variable.
You did not declare a variable for the Button. The reference for your button item will be in local of this procedure.
Once it goes out of scope and the GC collected it, the event will not trigger anymore.

Solution is to declare an SAPbouiCOM.Button object in a place where this button object will live as long as you need it.
Usually it is a variable in your class to handle this form.

Edy

Hi Roman,

Your code should be work. I have tested and works fine.

Check if your code doesn't have some EventFilter config.

My SAP B1 version is 9.1 PL 12.

Hope it helps.

Thanks, Diego. You was right - it's bad EventFilter in program. Now it works.
