WPF : Create CheckBox programmatically

Question

How can I create this from code ?

<CheckBox Command="{Binding Source={StaticResource VMLocator}, Path=TimeTableInformationViewModel.MyCommand }"
                  CommandParameter="{Binding valueFromInput}" />

I am not sure how to set Command property from behind code :

    public static DataTemplate CreateDataTemplate()
    {
        var block = new FrameworkElementFactory(typeof(CheckBox));
        block.SetBinding(CheckBox.CommandProperty, new Binding(""));
        DataTemplate newDataTemplate = new DataTemplate() { VisualTree = block };

    }

Have you tried anything yourself yet? Is there a particular part you're having trouble with? — Dan Puzey

Try this:

TypeOfYourObject vmLocator = (TypeOfYourObject)Resources["VMLocator"];
CheckBox checkBox = new CheckBox();
checkBox.Command = vmLocator.TimeTableInformationViewModel.MyCommand;
checkBox.CommandParameter = vmLocator.valueFromInput;

UPDATE >>>

There are a number of ways of doing this, but I have included a simple example that includes setting up a Binding... for more than this, please refer to the How do I build a DataTemplate in c# code? post to find out how to create a larger DataTemplate in code.

FrameworkElementFactory checkbox = new FrameworkElementFactory(typeof(CheckBox));
checkBox.Name = "aCheckBox";
checkBox.SetBinding(TextBlock.IsCheckedProperty, new Binding("YourBoolProperty"));
DataTemplate dataTemplate = new DataTemplate() { VisualTree = checkbox };
