thanks in advance......

Hi
For that you can use either validate or lost focus event
Private Sub SBO_Application_ItemEvent(ByVal FormUID As String, ByRef pVal As SAPbouiCOM.ItemEvent, ByRef BubbleEvent As Boolean) Handles SBO_Application.ItemEvent
        ' BubbleEvent sets the behavior of SAP Business One.
        ' False means that the application will not continue processing this event.
        ' Validate event
        If (pVal.FormType = 133) And (pVal.ItemUID = 38) And (pVal.ColUID = 1) And _
          (pVal.EventType = SAPbouiCOM.BoEventTypes.et_VALIDATE) Then
            If (pVal.Before_Action) Then
                'write your code
            End If
        End If
        'Lost focus event
        If (pVal.FormType = 133) And (pVal.ItemUID = 38) And (pVal.ColUID = 1) And _
         (pVal.EventType = SAPbouiCOM.BoEventTypes.et_LOST_FOCUS) Then
            If (pVal.Before_Action) Then
                'write your code
            End If
        End If
    End Sub
Hope this helps

ItemEvent - Event Type - Lost Focus Event

Hi,
Just want to ask whether what eventtype i should use for this situation.
I want to do something when the itemcode in marketing document been key in correctly.
At first i use the lost focus event. but i after i find that the lost focus event will keep on check where the itemcode is key in correct or not when it lost focus. Actually I want this effect but this will caurse the scoll bar cannot move.
For example. when i put the cursor in item code column. then i go and scoll the bar. it will keep on fire the lost focus event make me cannot scoll the bar or the matrix become wrong disappeared. Any idea on it?
Sorry i maybe not explain well. But i don know how to explain on it. Hope you all understand what I mean la.
Regards
Wong

Hi Wong
1st Try to split them
2nd use beforeAction=true and ItemChanged = True
If you have 2005/2007 version on the item code et_choose_from_list and validate are similar...
If pVal.ItemUID = "38" then
if pVal.ColUID = "1" And pVal.EventType = SAPbouiCOM.BoEventTypes.et_VALIDATE then
if pVal.ItemChanged=True And pVal.BeforeAction = True then
**** do something
end if
end if
end if
or
If pVal.ItemUID = "38" then
if pVal.ColUID = "1" And pVal.EventType = SAPbouiCOM.BoEventTypes.et_choose_from_list then
if pVal.BeforeAction = True then
**** do something
end if
end if
end if

Is there something like a lost focus event (like onBlur in JS)?

It is supposed to inherit InteractiveObject events such as flash.events.FocusEvent.FOCUS_OUT ("blur" in JS)

InputField's Lost Focus Event?

Dear All,
The input field does not seem to support an onLostFocus event.
Is there a work around?
How can the lost focus be detected?
Thanks and regards,

Hi,
As far as i know no work arounds, If you try work arounds it will be too costly in terms of performance.
Only option is users mercy and handle it in onEnter

How to catching Clear-Sort button event?

Does any one know how to catch the event when user click the Clear-ALL-Sort button? I would like to do somthing in Java by catching this event.
thanks in advance.
John

I'm not really sure what you mean.
LIke, I want to use the three event listener functions like a global or static function for all of the buttons which I think I've done for the most part.
However, I'm having an issue with the current state of the button. Like...
1 - on
2 - off
3 - off
4 - off
1 - off
2 - on
3 - off
4 - off
1 - off
2 - off
3 - on
4 - off
1 - off
2 - off
3 - off
4 - on
Really redundant right? So I want to beable to pass something through the event listener functions somehow so I only have to right the listener section once instead of 4 times.
Know what I mean? If I was in an external document class structure I could just re-create my own event listener class to pass aonther property/parameter. But I don't know what I can do within AS3 internally in the Flash movie to do this.
Just seems likes there should be a relatively simple way to do this, but I'm not sure how many errors I'd have to wade through or if it's even possible.

How to catch IE7 tab change event in Java Applet?

My applet have some modeless dialogs, When I start my applet with modeless dialog in tab1, if I swith to tab2, the modeless dialog of tab1 remains open.
So I want to catch the tab change event, and set modeless dialog invisible when tab changes.
Who knows the solutions.... Thanks

To get to the IE7 browser, you'll have to go through JNI if you're using Java to get to a C level interface. You'll have to write the code to interface to it also. IE7 does not have a Java interface, inface, MS has a vested interest in not supporting a Java interface. You'll have to look up the IE7 developers docs to see the OLE interface you'll have to hit.

Lost focus event litesner vs Mouse event litesner

hi all, I having problem with JSwing components in window environment. Below is the phenomenon.
1.) create a JFrame.
2.) drag JTextField and JButton put onto the JFrame.
3.) Add FocusLostEvent into the JTextField lostFocusListener.
4.) At the event code this:-
if (lostFocusEvent.isTemparory())
return;
javax.swing.JOptionPane dialog = new javax.swing.JOptionPane(
     "Error",                         javax.swing.JOptionPane.INFORMATION_MESSAGE,                         javax.swing.JOptionPane.DEFAULT_OPTION
dialog.createDialog(this,reslabels.getString("Error_Input_Error") ).show();
5.) run the program.
6.) focus your cursor in the JTextField. Next, use your mouse click on the JButton.
7.) You should see this. Message Dialog pop-up.
8.) Well, don't click the OK/NO button from the Dialog box.
9.) Now, point your mouse to the button and see what will happen to your JButton.
10.) The JButton is Armed.
By right the Jbutton should not be armed because the focus should has gained by the dialog box.
After all, we try create the same program using MS VC++. It does not have this problem because logical enough the focus has obtained by the dialog Box. Jbutton should not perform any action. Otherwise, it is some kind of degrade the dialog show modal.
If you has above experience and solutions, please do share with me. Thanks.

WWWizard, It doesn't work. below is the source code. Please take a look and compile it and run at your window environment.
1.) Focus you cursor at the JTextField.
2.) Once ready, click on the JButton. You should see the Dialog msg pop up. Do not close the Dialog at this moment.
3.) Move your mouse pointer to the JButton that you just clicked. Why the JButton is Armed? It shouldn't happen in window environment.
