  2. OnButtonClick - fired when the postback button (if displayed) beside the input control is clicked
  3. OnDisable - fired when the input is disabled
  4. OnEnable - fired when the input is enabled
  5. OnError - fired when the user enters invalid data
  6. OnFocus - fired when the input control gains focus
  7. OnKeyPress - fired when a keyboard key is pressed
  8. OnLoad - fired when the input control is loaded on the client
  9. OnMouseOut - fired when the mouse cursor leaves the input area
  10. OnMouseOver - fired when the mouse cursor is over the input
  11. OnMouseOut - fired when the mouse cursor leaves the input area
  12. OnMouseOver - fired when the mouse cursor is over the input
  13. OnMoveDown - fired when the user decreases the value of any enumeration or numeric range mask part of RadMaskedTextBox (with either keyboard arrow keys or mouse wheel)
  14. OnMoveUp - fired when the user increases the value of any enumeration or numeric range mask part of RadMaskedTextBox (with either keyboard arrow keys or mouse wheel)
  15. OnValueChanged - fired when the data entry in the input is changed by the user (right after the control loses focus)
