Blazor Input Mask - Custom Mask Patterns
This example demonstrates the custom mask functionalities of the MaskedTextBox component. Enter time value in meridiem format, and enter IP value in numeric format.
Properties
The custom mask is achieved by the following ways:
Custom characters:
You can form the mask with any non-mask elements (literals), and you can configure the behavior of that non-mask element as mask element through the CustomCharacters property.
In this demo, the "Time" mask '99 : 99 >PM' contains the literals P and M, where it is configured to allow the inputs as 'P', 'A', 'p', 'a', and 'M', 'm'.
Regular expression:
Alternatively, you can use the regular expressions as mask element to validate the input of the particular input place.
Here, in the "IP address" example, each character is masked by an regular expression to allow a particular range of values.
