Add MaxCharactersAllowed property to TextBox same as MaxLength

[zohaib82]

Hi,

In my project I set max char allowed for TextBox using following

TextBox.MaxLength = 20;

I want add one more property as MaxCharactersAllowed. This will work same as MaxLength

TextBox.MaxCharactersAllowed = 20;

I found that TextBox properties written in "System.Windows.Controls.TextBox.cs"

Any idea how to add property?

- Thanks
