Ways to Use Button Control: WPF

Button, a simple and small name to listen in all the programming languages. All the windows, forms, dialog boxes and even user controls mostly use this button to be performed some action. Open, close, submitting a form and whatever to do can also be performed by button.

Button control is of content control type, means it have a content property to be assigned by us. The content may be a string or anything that can be used under the conditions.

<Button Name=”loginButton” Content=”Click to Login”></Button>

The above button will look like a standard button control and saying the user to click if he/she want to login. Actually, it only have its content property, doesn’t have defined any action to be performed when user will click. So click event have to be defined to perform an action when user click on it.

<Button Name="loginButton" Content="Click to Login" Click="loginButton_Click"></Button>

In the code behind file the click event is generated like the following code in C# language

private void loginButton_Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("You are logged in");
}

The message box is not pre-defined. When user click on the button it will show the above message each time. We can bind our button to the commands defined in a class to be performed the same action as in click event. The following code is used to bind a button to a command.

<Button Name="loginButton" Content="Click to Login" Command="{Binding ClickCommand}"></Button>

The command can be simply defined as the below code in C# language:

public ICommand ClickCommand
{
get
{
return showDetailCommand;
}
}

ICommand is the interface that is used for this command binding. We will learn it later. We can use a button as per our requirements using its properties.
