One issue that you may have is when you need to bind a control (such as a ListBox or a DataGrid) in the View to a collection exposed from the ViewModel (as a property) but don t have that collection available at the time that the ViewModel is instantiated. For example, say you need to bind a ListBox control in the View to a collection of objects exposed by the ViewModel. However, the ViewModel doesn t have that collection available when it is instantiated, as it has to go off and retrieve the collection from the server. How do you handle this problem The answer is to have the ViewModel expose the collection as a property of type ObservableCollection. When the ViewModel is instantiated, an empty ObservableCollection should be instantiated and made available to the View for the ListBox control to bind to. Then when the collection has been retrieved from the server, its contents should be added to the empty ObservableCollection collection (instead of replacing it), which (as we discussed back in 6, Implementing Summary Lists ) the View is listening to for changes and updates accordingly as the data becomes available. c# pdf parser: Download file in windows C# application - CodeProject c# populate pdf form fields GitHub - asido/ EpubSharp : C# library for reading EPUB file format

Note There will also often be an additional property exposed from the ViewModel named IsBusy. This is a Boolean value indicating whether or not the ViewModel is waiting for a response from the server (when retrieving or persisting Models (also known as entities), which a control such as the BusyIndicator control in your View can then bind to (as described in 6, Implementing Summary Lists ). You can then bind this IsBusy property to the IsBusy property on a BusyIndicator control (using one-way binding), which will enable the View to display the indicator whilst the ViewModel is busy communicating with the server, informing the user that the application is waiting for data to be returned. However, to keep this scenario simple, we ll omit this property and binding for the time being. pdf annotation in c#: C# tutorial: PDF Annotations - worldbestlearningcenter.com free pdf library c# .net The C# PDF Library | Iron PDF

I Tip One way to eliminate the deadlock issue in this sample is to acquire and release locks in the same order in both threads. Although there is still no synchronization and the output is not guaranteed correct, the program will complete its iterations as expected. Operations (containing logic and behavior) will be exposed from your ViewModel as public methods. For example, in our login screen scenario, we have a BeginLogin method in the ViewModel and a Login button in the View. The BeginLogin method needs to be invoked in response to the user clicking the Login button in the View (hence the method should be invoked in response to the Click event of the button being raised). There are three ways you can invoke an operation on a ViewModel in Silverlight: In the code-behind Using an action or behavior that will be triggered by an event being raised on a control Using commands (new to Silverlight 4) >>> $("<img />", { "src":"not/an/image.png", ...ot be loaded!"); }) .appendTo("body"); [ img image.png ] The image cannot be loaded! c# populate pdf form fields How to create a pdf file in C# - CSharp - Net-Informations.Com

Invoking the operation in the code-behind is the traditional solution to this problem, but it doesn t typically conform to the MVVM way of interacting between the View and the ViewModel. Therefore, we ll look instead at how to implement the other two methods now (as pictured in Figure 12-5). We discussed triggers, actions, and behaviors back in 10, Advanced XAML and Data Binding; these aren t native functionality available in Silverlight but are available using the Expression Blend Interactivity library. You can leverage the CallMethodAction action from this library to call a method on the ViewModel, which provides a solution for invoking operations on the ViewModel from the View. In other words, when something happens in the user interface, call a method in the ViewModel. For example, to call the Login method on the ViewModel in response to the Click event of the button, you would add the following XAML (in bold) to the button: <Button Name="LoginButton" Content="Log In" Height="30" Width="90"> <i:Interaction.Triggers> <i:EventTrigger EventName="Click"> <ei:CallMethodAction TargetObject="{Binding}" MethodName="Login"/> </i:EventTrigger> </i:Interaction.Triggers> </Button> .scroll() Race conditions occur when multiple threads or processes are attempting to access a single resource, resulting in unexpected behavior or security flaws when events occur out of sequence. For example, consider the simple computation in Listing 3 2. Listing 3 2. A Simple Loop to Update an Integer Value using System; namespace 3 { class Program { static int x = 0; static void Main(string[] args) { for (int i = 0; i < 3; i++) { x++; } Console.WriteLine("{0}", x); Console.ReadLine(); } } } how to use abcpdf in c# Exporting to PDF from GridView in C# Windows Forms Applications
