Question

Is it possible to hide a part of a WPF control? .NET 4 has a DatePicker which renders 4 parts, according to MSDN. Is it possible to hide (in my case) the TextBox part (probably named PART_TextBox)?

I have seen examples of styling the DatePicker completely, and it involves alot of XAML, when all I want to do is hide one part of the control.

Well, I have a solution for your case 🙂

class MyDateTimePicker : DatePicker
{
    public override void OnApplyTemplate()
    {
        base.OnApplyTemplate();

        var textBox = this.Template.FindName("PART_TextBox", this) as UIElement;
        if (textBox != null)
        {
            textBox.Visibility = Visibility.Hidden;
        }
    }
}
