contextmenu

I'm having some difficulty with Context Menu commands on my View Model. I'm implementing the ICommand interface for each command within the View Model, then creating a ContextMenu within the resources of the View (MainWindow), and using a CommandReference from the MVVMToolkit to access the current DataContext (ViewModel) Commands. When I debug the application, it appears that the CanExecute method on the command is not being called except at the creation of the window, therefore my Context MenuItems are not being enabled or disabled as I would have expected. I've cooked up a simple sample (

I am trying to late-bind context menus to elements, using the ContextMenu plugin . So on the first right-click on those elements, I would like to : intercept the right-click through a live event on a certain "uncontextmenued" class, determine if the data('events').contextmenu exists, if not, attach the context-menu (and change the class to avoid re-throwing this live process), re-throw the right-click event to show the right-click. I'm having trouble with the last item. jQuery allows to .click() or to .trigger('click') , which simulate a left-click, but there seems not to be a way to fire a

var OrderInfo = {"ProductID": "ProductIDValue", "ProductName": "ProductName", "Quantity": 1, "Amount": 9999, "SLQuantity": 9999, "SLDate": "08/03/2010" }; var DTO = { 'OrderInfo': OrderInfo }; $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "JasonHandler.ashx", data: JSON.stringify(DTO), dataType: "json" }); I'm trying to retrieve posted JSON data on server side in an ASHX file via this code: string strrequest = context.Request["OrderInfo"]; but it always return null. What Am I doing wrong? ronaldwidha get the request body from HttpContext.Current.Request

My question can be split into three: Is it possible to hide/remove arbitrary context menu items in Eclipse (3.6) by ... standard UI? some existing plug-in? custom plug-in? I failed to find ways to do this by methods 1 and 2. If the only option is creating custom plug-in, could anyone push me towards the right direction where to start (I have some experience in Java, but not in Eclipse plug-ins). You can hide menus or menu entries through the standard GUI: see help To hide a menu item or toolbar button: Switch to the perspective that you want to configure. Select Window > Customize Perspective.

<Button Name="btnFoo" Content="Foo" > <Button.ContextMenu Placement="Bottom" PlacementTarget="btnFoo"> <MenuItem Header="Bar" /> </Button.ContextMenu> </Button> gives me a runtime error 'UIElement' type does not have a public TypeConverter class I also tried <Button Name="btnFoo" Content="Foo" > <Button.ContextMenu Placement="Bottom" PlacementTarget="{Binding ElementName=btnFoo}"> <MenuItem Header="Bar" /> </Button.ContextMenu> </Button> and that put the ContextMenu in the top left corner of my screen, rather than at the Button You should be setting the ContextMenuService.Placement attached

I'm using jsTree 3.0.0 and I need to modify the context in one of the following ways: Change label language for the default items, disable some default items and add new items. Rewrite all items and bind to some new items the create, rename and delete function. I tried several approaches but nothing worked. For example, this returns Uncaught TypeError: Object [object global] has no method 'create' when I click on create. "contextmenu":{ "items": function($node) { return { createItem : { "label" : "Create New Branch", "action" : function(obj) { this.create(obj); alert(obj.text())}, "_class" :

I have a problem when binding a command in a context menu on a usercontrol that is on a tab page. The first time I use the menu (right-click on the tab) it works great, but if I switch tab the command will use the databound instance that was used the first time. If I put a button that is bound to the command in the usercontrol it works as expected... Can someone please tell me what I'm doing wrong?? This is a test project that exposes the problem: App.xaml.cs: public partial class App : Application { protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); CompanyViewModel
