Hello,

You can create a custom Entry, detect the input characters, if the input format is correct and convert it to the MM/dd/yyyy format.

public class MyEntry : Entry
    {
        public MyEntry(){

           
        }
        protected override void OnTextChanged(string oldValue, string newValue)
        {
            base.OnTextChanged(oldValue, newValue);
            DateTime date;
            if (newValue != null)
            {
                if (DateTime.TryParseExact(newValue, "MMddyyyy", null, System.Globalization.DateTimeStyles.None, out date))
                {
                    this.Text = date.ToString("MM/dd/yyyy");
                    //Console.WriteLine();
                }
                else
                {
                    Console.WriteLine("The number entered is not a valid date format!");
                }                                              
        }
    }

You can use it in the layout like following code.

 <local:MyEntry Keyboard="Numeric"></local:MyEntry>
