I want to format my textbox to have 4 numerical integers at all times. Example 90 would equal 0090. I also do not want letters to be entered. Any help would be greatly appreciated

    Is this WinForms or Web?

You mean like a Masked Textbox? You can use a mask of "0000" to ensure only numbers can be entered, and that you need four of them.

If it's for asp.net you could look at a MaskedEdit or a jQuery solution.

  • textBox1.Text = string.Format("{0:0000}", someNumber); This is the way I have it I am new to C# a huge leap for me from Visual Basic

  • Is one of the rare occasions where a masked textbox is useful (often, it is too limited).
