Getting into the first serious WPF project. It seems like there are a lot of basic controls flat out missing. Specifically, I am looking for the Numeric UpDown control. W
The given answers are OK. However, I wanted the buttons to auto hide, when mouse leave the control. Here is my code based on vercin answer above:

public partial class IntegerTextBox : UserControl
{
public IntegerTextBox()
{
InitializeComponent();
}
public int Maximum
{
get { return (int)GetValue(MaximumProperty); }
set { SetValue(MaximumProperty, value); }
}
public readonly static DependencyProperty MaximumProperty = DependencyProperty.Register(
"Maximum", typeof(int), typeof(IntegerTextBox), new UIPropertyMetadata(int.MaxValue));
public int Minimum
{
get { return (int)GetValue(MinimumProperty); }
set { SetValue(MinimumProperty, value); }
}
public readonly static DependencyProperty MinimumProperty = DependencyProperty.Register(
"Minimum", typeof(int), typeof(IntegerTextBox), new UIPropertyMetadata(int.MinValue));
public int Value
{
get { return (int)GetValue(ValueProperty); }
set { SetCurrentValue(ValueProperty, value); }
}
public readonly static DependencyProperty ValueProperty = DependencyProperty.Register(
"Value", typeof(int), typeof(IntegerTextBox), new UIPropertyMetadata(0, (o,e)=>
{
IntegerTextBox tb = (IntegerTextBox)o;
tb.RaiseValueChangedEvent(e);
}));
public event EventHandler ValueChanged;
private void RaiseValueChangedEvent(DependencyPropertyChangedEventArgs e)
{
ValueChanged?.Invoke(this, e);
}
public int Step
{
get { return (int)GetValue(StepProperty); }
set { SetValue(StepProperty, value); }
}
public readonly static DependencyProperty StepProperty = DependencyProperty.Register(
"Step", typeof(int), typeof(IntegerTextBox), new UIPropertyMetadata(1));
RepeatButton _UpButton;
RepeatButton _DownButton;
public override void OnApplyTemplate()
{
base.OnApplyTemplate();

}
private void btup_Click(object sender, RoutedEventArgs e)
