![]() ![]() Here, I will explain the function, given above. Private void executemethod(object parameter) private bool canexecutemethod(object parameter) Multi Binding is already discussed in Explain Multi Binding In MVVM - WPF article. In command parameters, we have to pass multiple (two) parameters, where one is check box content name and another is "IsChecked". Base on its action we perform our further operation. When command fires from the view screen, we have to decide that, whether the user checks the check box or un-checks the check box. On the other hand, execute method contains the actual logic like assigning all the checked check box values to the ‘Name’ property. Public event EventHandler CanExecuteChangedĪdd Īlso, we create two new methods - canexecute and execute, where canexecute allows to fire execute method or not. ![]() Public Rela圜ommand(Action executemethod,Func canexecutemethod) This is taught in the ICommand Interface In MVVM - WPF article.Ĭode - Rala圜ommand.cs public class Rela圜ommand:ICommand Thus, we create the Relay Command class, which implements the ICommand interface. In simple words, we have to create a checkbox, which is checked on the change of the event in Windows form Application, but in MVVM pattern, we say that we have to create a command for the same. Here, when the user checked the checkbox, we have to display its selected checkbox content in the textbox, so first we have to create a command for the checkbox, which is checked. Thus, we create a WPF Window, as shown below. The user has to select the check box and whatever check box the user selects, you have to display the list of all the checked checkboxes in the text box. Let’s take an example to create one WPF Application, put four checkboxes and put one text box in it. Before starting this article please read Explain INotifyPropert圜hanged In WPF - MVVM and ICommand Interface In MVVM - WPF article. Today, I will explain how to use checkbox in WPF using MVVM pattern.
