I have a CF application.
In some view i have a ContextMenu that shows OK.
Is there a way to catch an event as the menu is drawn/opened?
I need to do some things just as the menu is drawn, because doing it later (on menuitem click) is already too late.

update ... I used popup event.

Working with the RadDesktopAlert WinForms component by Telerik, I am wondering how can I perform an action when the user clicks anywhere on the alert window.
To put it blunt, the buttons suck, and it is much more natural (easier) for a user to just click anywhere in the window. I checked the basics, and there doesn't appear to be an event for "Click", nor does it appear to expose it's Hwnd or Handle.
The events that are available are
Closed
Closing
Disposed
Disposing
Opened
Opening
PropertyChanged
RadPropertyChanged
RadPropertyChanging
The problem with the buttons is the UI looks wacky when trying to right-align, and the "click" event doesn't fire unless you click well inside the button - TWICE. So using the Buttons are not an option. What I am looking for is a place to write code that runs when the user clicks anywhere on the RadDesktopAlert box.
Thanks in advance.
The RadDesktopAlert component, has a Popup property, which holds the actual popup element. You can use its Click event for the purpose:
AddHandler radDesktopAlert1.Popup.Click, AddressOf Popup_Click
Visual Studio with VB.net: If I create a copy of a button on the forms designer, the click event is added to the click event handler of the source button.
How do I change this behaviour ? I want the click event of the second button be wired to a totally new click handler code, not to the already existing one of the first button.
There are two ways to copy a button.
CTRL+C / CTRL+V (or same with right click menu). This will create a new button with a new event handler. Note that this new event handler is not created automatically, but will be created on button click in VS designer.
CTRL + drag a control into a new location. This will create a copy with the same event handler, i.e. add an event handler to already existing one. This is the behavior you are seeing.
I'd be interested to know the official reference about this behavior, found the above by experiment. I've used CTRL + drag copy method 95% of the time, and had the same question for quite a while. Fortunately, there is a quick fix for event wiring - read below.
If you used the wrong method, you can manually delete the wiring code (the second handles clause), then double-click the button in question to create new click event handler for it (not a big deal).
I can't seem to get the Open Panel's New Document button to work. Currently I am just using the default application provided Open Panel (iCloud enabled OS X app) which has a New Document button at bottom left of the window.
However I just get a system beep when I click on it, I would expect this button would do the same as File->New menu option but it does nothing other than beep.
How can I either enable this button to simply create a new blank file or remove it altogether.
Finally I figured it out.
It seems the New Document button is somehow hardware to the CMD+N keystrokes. I had reassigned CMD+N to apply Normal style to text and this breaks the New Document button.
Seems odd that the button is not wired to newDocument method on First Responder rather than to a keystroke combination.
EDIT
I logged a Bug ID# 14886108 and it seems it may be fixed in Mavericks
How can I unselect all ListView items when I click outside the ListView in xaml for Windows Store Application?
When I add handlers to LostFocus event I unselect all but in case when I just want to chenge selected item LostFocus event also triggers.
Can anyone share the solution of this problem?
How about waiting a bit after LostFocus to see if it was indeed lost. Like by calling RunAsync on Dispatcher? Seems a bit like a hack, but it could work.
In Sencha-touch, how can I make a form popup when a user clicks on an item in a list?
I would attach a listener to the 'itemtap' or 'itemdoubletap' events within your Ext.List instance which triggers the display of your form. That's off the top of my head as I haven't touched (rimshot) Sencha Touch since before it came out of beta.

You might want to explore disclosures, which place an arrow on the list item for the user to click, or as Wilhelm says, attach to a regular tap or selection event.
For 'modal' popups, simply create a panel with floating:true. See the docs at http://dev.sencha.com/deploy/touch/docs/?class=Ext.Panel and the examples in the User Interface / Overlays section of http://dev.sencha.com/deploy/touch/examples/kitchensink/
for this i will guide you please go through link which i have give will help You alot
