To set the dialog box options, follow the next steps:
- In the Apply to field drop-down menu select the text field on which to apply the server behavior.
- In the Mask drop-down menu select one of the predefined masks or create your own custom mask. To learn more about this, read the note below.
- The Restrict to mask checkbox enables the option of limiting the text field input to the mask type. If you do not check it, you can enter at most as many characters as the mask has (so less, but not more).
- In the Default value text box enter a starting value for the masked text field. You can also select it from one of the available recordsets in your page by using the lightning icon on the right.
- The three buttons on the right of the interface offer you the next functionalities:
· Click OK when you are done configuring the server behavior.
· Click Cancel to exit without applying the new settings.
· The Help button opens this help page.
Note: A mask is a validation format that provides an easy way to define your own rule for acceptable field input. The rule you write determines what type of input is allowed in each character position and the length of the entry. For the Masked Text Field widget, the following characters have special meanings:
- A – Allows only the UNICODE alphabetic characters (upper or lower-case) inside the following ranges:
These are UTF8 character codes from the following UNICODE blocks:
· Basic Latin
· Latin Extended-A
· Latin Extended-B
- X – Allows all the characters that A replaces, plus all the digits (0-9).
- 9 – Allows a number: 0-9.
- ? – Allows any character.
- If you enter any other character (other than the above) it will be inserted into the field data.
Let’s consider the following example for a Mask format: AAA?AAAA?AAAAA. The “Try this today” input is allowed, while the “Try this tomorrow” or “Try it 5 times” inputs are not allowed (the first one is too long, the second one contains characters not accepted by the mask).
