Creating Numeric Textbox (.Net 4.0 - Winforms)
May 12, 2012I'm trying to create my own numeric textbox that will handle decimal as well as whole number values. The concept is, unlike the regular textbox, this one will accept a value of 'Double' data type and show it with proper formatting e.g. Leading Digits, Digit Grouping etc. When the textbox value is called, it returns the actual 'Double' data type value. The entire thing is done through the 'Text' property; wherein the regular 'Text' property is shadowed and one with 'Double' data type is used.

If nothing or a char or string is entered, I want to inform them to enter the number and clear the box. From a suggestion somewhere it was said to simply use validating. I thought e.handled was correct by that doesn't show up as an option. It works if the input is a number. If not, the messagebox shows and closes on OK but I can't do anything else. Any click (even to 'X' the window) anywhere brings up the messagebox. This is basically what I've tried:

I have found a couple of possible methods, although the sites which I found them where very unclear on how they actually work. I feel strongly that I should know how all of my own programs work >_>
I have no actually got this to work with my program yet. Are there better methods than this?
