The suggested solution to this problem:

private void ultraMaskedEdit1_KeyPress(object sender, KeyPressEventArgs e)
{
   if (Char.IsDigit(e.KeyChar))
      e.Handled = true;
}

If you have a mask "AA######A" then the first 2 'A's will now accept only letters but the '#' mask will not accept a number because it has been rejected by the key press event. The code could be extended to cope with this but if that was the case you have just ended up writing a custom mask input control to cover missing features in the original (possibly?)

Hello,

Isn't the above solution sufficient enough for you?

Did you try it:

private void ultraMaskedEdit1_KeyPress(object sender, KeyPressEventArgs e)
{
   if (Char.IsDigit(e.KeyChar))
      e.Handled = true;
}

I don't know the reason why there is no alpha-only specifier but you could use the 'A' specifier ad handle the KeyPress event and set the Handled property of the event args to true if the character is numeric, thus preventing numeric entry.
