You can:

  1. Use MaskedTextBox
  2. Use NumericUpDown
  3. Attach a javascript event handler to handle “keypress”, see attached screenshot.
  4. Attach a javascript event handle in code:
 this.textBox1.AddClientEventListener("keypress", @"
 var e = arguments[0];
 if ('0123456789'.indexOf(e.getKeyIdentifier()) === -1)
 e.stop();
 ");

It’s how it works in the browser.

The InputType property of the TextBox allows you to use the native implementation of the different types. It is not a Wisej widget – it’s exactly as the browser implements it.

It’s different on each browser and on each OS.

    It works. The handled property is set to true and you will find it in the different handlers related to KeyPress. What you cannot do is change the keyboard behavior of a browser on a client from server code. Wisej makes it too easy to forget that the browser and server are different machines.
