如何在WPF中设置复选框的初始状态(在XAML或代码中)?

IsChecked="True"

XAML编号:

<!-- Initialized checked -->
<CheckBox x:Name="cbxSwitch" IsChecked="True" Content="Simple switch" />

<!-- Initialized in third state -->
<CheckBox x:Name="cbxSwitch3" Content="3 state switch"
    IsThreeState="True" IsChecked="{x:Null}" />

反恐精英:

// Two-state CheckBox doesn't require checking null
if (cbxSwitch.IsChecked == true)
{
    // Do something if selected
}

// In three-state CheckBox, IsChecked may be true, false or null
if (cbxSwitch3.IsChecked ?? false)
{
    // Do something only if IsChecked==true (selected)
}
