Disabling a button​

Disabled Button

<Button IsEnabled="False" Content="Button" />

In C#, you can enable/disable a button using button.IsEnabled = booleanValue;.

Hiding a button​

Using Visibility="Collapsed" makes the component disappear as if it doesn't exist. Use Visibility="Visible" to show it.

<Button Name="Btn" Content="Button" Visibility="Collapsed" />

To show/hide a disabled button in C#, do the following:

/* Show */
Btn.Visibility = Visibility.Visible;

/* Hide */
Btn.Visibility = Visibility.Collapsed;

Calling a function​

C#​

void Button_Click(object sender, RoutedEventArgs e)
{
    // Process
}

XAML​

<Button Click="Button_Click" Content="Button" />
