The MaskedEdit control is an ASP.NET AJAX control that can be attached to a TextBox control. The supported data formats are: Number, Date, Time, and DateTime. MaskedEdit uses the culture settings specified in the CultureName property. If none is specified the culture setting will be the same as the page: English (United States).

The MaskedEdit control has to be integrated with the MaskedEditValidator to verify the input.

It validates date formats entering. It is also used for time and number formats also.
