Hi

We need MaskedTextBox to accept uppercase letters only, which can be achieved by defining custom mask rule for it. However, that requires the user to enter uppercase letters manually. Can a feature request be made for the functionality that even if user enters lowercase letters, it can be displayed as uppercase letters?

Example use case of this feature - Postal codes input is one of the example use cases. It requires letters to be uppercase, and when user provides lowercase input, it either needs to be processed separately to convert to uppercase or the input gets ignored with default behavior.

Currently, the MaskedTextBox component does not support RTL. It would be nice to have RTL support in all components.

MaskedTextBox, there is no support "placeholder" text in the control prior to user input. It would be nice if, instead of showing the mask, it could show placeholder text like native HTML input box does until you begin typing then it would show the mask prompts. Full support for styling the placeholder text using the ::placeholder pseudo class would also be required.
