Suppose I want to allow the user to enter numbers, letters, and some special characters like *, $.
Plus limit to 3 characters.
How do I create a Mask for the AjaxControlToolKit MaskedEditExtender to allow only those characters?
I thought the mask would look something like:
"{9$\*\$}{9$\*\$}{9$\*\$}"
I started with this:
"{9$}{9$}{9$}"
I can't enter any characters into the TextBox.
According to one article the {} characters are "repetition delimiters".
So I thought using those parens was the correct syntax usage for setting the mask to allow a set of characters for a single character position in the textbox.
Thanks, Ed
