Hi,

If you need entry without prompts, then you should use WebTextEdit. Idea behind WebMaskEdit is provide strict length of entry.

It is very easy to filter entry. Example of editor which has max length of 30 and allows only A-Z and a-z entries:

<script type="text/javascript">
function WebTextEdit1_KeyPress(oEdit, keyCode, oEvent)
{
 //------------------
 // cancel all characters which are smaller than A and larger than z
 // A==65, z==122
 if(keyCode < 65 || keyCode > 122)
  oEvent.cancel = true;
 //------------------
 // cancel all characters which are between Z and a
 // Z==90, a==97
 if(keyCode > 90 && keyCode < 97)
  oEvent.cancel = true;
}
</script>
