What have you tried so far? You ask for code but have not shared any effort made from your side.

No one is going to post any code for you.

Go through each of these articles and try implementing validation logic on your own.

The question is over a year old and the OP specifically also said "Textbox (Include Char and Numbers & Starts with Char)" - your code only validates for integers only, not numbers
