Numeric TextBox Controls

Peter's Data Entry Suite includes four textboxes that handle numeric data. Here are the features of each numeric TextBox.

IntegerTextBox - Allows only integers. Options include only allowing positive numbers and showing the thousands separator.
DecimalTextBox - Allows decimal values. Options include only allowing positive numbers, showing the thousands separator, establishing a limit of decimal digits, and adding trailing zeros.
CurrencyTextBox - Allows currency values. Options include allowing the currency symbol, allowing only positive numbers, allowing extra decimal digits, and showing the thousands separator.
PercentTextBox - Allows percentage values. Options include allowing the percentage symbol and support for either integer or decimal formatting.

They all offer these features:

Filter keystrokes and reformat as you exit the field.
Use fuzzy logic to handle minor errors like extra decimal characters or back-to-back thousands separators.
Supports any culture by using the Culture of the page or one you assign.
Offer spinner buttons to increment and decrement their values.
Get and set the value of the textbox through a property reflecting the datatype (integer or double) instead of using the Text property and converting it yourself.
It inherits from the DES TextBox, gaining all of the javascript technologies from its ancestor such as "value when blank", interactive hints, and autotabbing.
