numeric only textbox

[Magiaus]

i thought .net had a property to do this but i can't find it. what is the .net way to do it?

with keypress event

Private Sub OnKeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)

   e.Handled = (Not Char.IsControl(e.KeyChar)) AndAlso _
     (Not Char.IsNumber(e.KeyChar)) AndAlso _
     (Not (Char.IsPunctuation(e.KeyChar) And _
     (((e.KeyChar = ".") And
     (Text.IndexOf(".") = -1)) Or _
     ((e.KeyChar = "-") And (SelectionStart = 0)))))

End Sub

that allows decimals and negative numbers also

also take not that if it is something you may use more often, you can create a class that inherits TextBox and change Private to Protected Overrides for the event. Now you have a reusable numeric only textbox class that retains all the orginal textbox functionality

Isnt inheritance awesome?
