[WPF] Automatically sort a GridView (continued) » Thomas Levesque's .NET blog

November » 2015 » Thomas Levesque's .NET blog. Async code is a great way to keep your app’s UI responsive.

November » 2015 » Thomas Levesque's .NET blog

You can start an async operation from the UI thread, await it without blocking the UI thread, and naturally resume on the UI thread when it’s done. This is a very powerful feature, and most of the time you don’t even need to think about it; it “just works”. However, this works only if the async operation is started from a thread that has a synchronization context (such as the UI thread in Windows Forms, WPF or WinRT). If you don’t have a sync context when the async operation starts, or if resuming on the sync context is explicitly disabled with ConfigureAwait(false), then the method resumes on a thread pool thread after the await, and there is no obvious way to get back to the UI thread.

WPF ListView ItemContainerStyle - How to Apply. ListView ItemContainerStyle specifies a style that is used by every generated ListViewItem for styling it.

WPF ListView ItemContainerStyle - How to Apply

You can create a Style inline or in the Resources section and set the ItemContainerStyle property of ListView. You can set ItemContainerStyle as StaticResource or DynamicResource. When to Use? By default you cannot modify style of ListViewItem in WPF ListView. Only by using ItemContainerStyle, you can change the styles of every ListViewItem. ItemContainerStyle example In the above example, I have set ItemContainerStyle and change the Background color of ListViewItem to AliceBlue, BorderBrush to BlanchedAlmond color, and set the BorderThickness to 2. I have also set the Trigger that will execute when ListViewItem is selected. WPF MultiTrigger and MultiDataTrigger - The complete WPF tutorial.

In the previous chapter, we worked with triggers to get dynamic styles.

WPF MultiTrigger and MultiDataTrigger - The complete WPF tutorial

So far they have all been based on a single property, but WPF also supports multi triggers, which can monitor two or more property conditions and only trigger once all of them are satisfied. There are two types of multi triggers: The MultiTrigger, which just like the regular Trigger works on dependency properties, and then the MultiDataTrigger, which works by binding to any kind of property. Let's start with a quick example on how to use the MultiTrigger. MultiTrigger. How to Remove default Image of DatePicker. C# - Find Item in ObservableCollection without using a loop. How to send string and content messages with MVVM Light Messenger. Home > C#, MVVM, Windows Phone, WinRT > How to send string and content messages with MVVM Light Messenger The Messenger component of MVVM Light easily allows to pass data between classes of our app: To send an object, we simply need to pass it to the Messenger.Send method.

How to send string and content messages with MVVM Light Messenger

But what if we just want to send string messages, like GotoDetailsPage or CloseApp? In this case, we don’t want to create a new class only to pass a string. We can instead use the NotificationMessage object that comes with MVVM Light: At lines 8-18, we check the Notification property to determine the specific message that has been sent. We have also a generic version of NotificationMessage that we can use when we want to send an object along with a string message, which for example specifies the action that we want to perform: The generic version of NotificationMessage exposes a Content property that contains the actual object. C# - WPF DatePicker, display todays date with binding to property. Making Timeline Control for DataGrid in WPF. In this article we will see how we can make a Timeline control in WPF.

Making Timeline Control for DataGrid in WPF

Making Timeline Control for DataGrid In WPF Introduction Creating A WPF Project Fire up Visual Studio 2010, create a WPF Application, and name it as TimelineSample.

As you see from the above xaml display, we have Minute rectangles Visibility made as Hidden. LINQ Inner Join with AND and OR condition. Posted By : Shailendra Chauhan, 16 Jul 2014 Updated On : 16 Jul 2014 LINQ has a JOIN query operator that provides SQL JOIN like behavior and syntax.

LINQ Inner Join with AND and OR condition

As you know, Inner join returns only those records or rows that match or exists in both the tables. The simple inner join example is given below: DataContext context = new DataContext();var q = (from pd in context.Products join od in context.Orders on pd.ProductID equals od.ProductID orderby od.OrderID select new { od.OrderID, pd.ProductID, pd.Name, pd.UnitPrice, od.Quantity, od.Price, }).ToList(); Inner Join with AND condition Sometimes, you need to apply inner join with and condition.

DataContext context = new DataContext();var q=from cust in context.tblCustomer join ord in context.tblOrder// Both anonymous types should have exact same number of properties having same name and datatype on new {a=(int?) // Generated SQLSELECT [t0]. Note Inner Join with OR condition Sometimes, you need to apply inner join with or condition. Retourner l'union définie de deux séquences.

MVVM : Event Routing to the Child ViewModel. Introduction Currently, MVVM pattern is the most recommended pattern for designing the architecture of the WPF application.

MVVM : Event Routing to the Child ViewModel

MVVM principle is based on the following component: Generally, we design our application in the same way where there is one ViewModel for a View. ViewModel is responsible to provide/update the data and event handling for its view. It’s clear from the above diagram that for controls such as Button, ContextMenu etc there is an event handler e.g. WPF INotifyPropertyChanged.

Quand un contrôle ListView ou GridView contient de nombreux éléments et que l’utilisateur les fait défiler rapidement, l’affichage intégral du contenu de chaque élément peut utiliser un grand nombre des ressources de l’interface utilisateur.

WPF Calendar View, Schedule Control, Scheduler. Wpf-Schedule control provides you with the great multi-user calendar control including powerful recurring appointments engine. Our scheduler control uses the Model/View architecture where actual appointments are separated from the User Interface presentation. That way the appointments can be presented in number of different views and new views can be added easily.

Muhammad Shujaat Siddiqi: Binding ObservableCollection to Text Properties. In this post we will be discussing the issue when we bind a collection based (ObservableCollection) property to some scalar DependencyProperty e.g. Text property of a TextBlock. Let's create a sample MVVM Light based WPF application. Note: Yes, you would need an installation of MVVM Light in order to follow this example. Let's update MainWindow's definition as follows: The above view has some expectations from view model. A Simple WPF Application Implementing MVVM.

How cool is that, huh?). WPF MVVM Pattern: A Simple Tutorial for Absolute Beginners. As part of learning MVVM pattern I tried to search many sites and blogs and found most of them are explained in a complicated manner. After some research I cracked the very basic steps in MVVM pattern, and then trying to write MVVM tutorials for absolute beginners. I don't think much more time or words spend for explaining various part of MVVM and the relationship between MVVM and WPF. If you go to the depth of WPF you will realize that MVVM is the best suitable pattern for WPF (You might not understand the difference between these two) . As a formal procedure I am giving a simple diagram and definition for MVVM I start this tutorial with two examples, i.e WpfSimple.csproj and WpfMvvmTest.csproj For the sake of simplicity, the first project (WpfSimple.csproj) avoids the Model object (an example with Model will come later).

In the example WpfSimple, the view contains only a Button and no code behind, but its click event is loosely bound with ViewModel. The View. Stretching the items in a WPF ListView within a ViewBox.
