Add MaxCharactersAllowed property to TextBox same as MaxLength

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

Question :
Why do you want to make a Property that does the same thing ?

1st solution (easy way) :
Manage the keydown event and check how many characters are inside the textbox, if more discard any new

2nd solution (hard way)
extend your controls properties (Check class extensions)

I would create a new user control inherited from TextBox, add the new property, and add a function to handle the key press event. Then create a delagate to point to the keypress handler function and use the delagate to register the keypressefvent of the the TextBox to the key press event handler.

In my idead you could create your custom control and then listen for Windows event messages passed to your application.

Not sure if that helps
