Hi all,

how do I set a Textbox to only accept numerical values in vb .net

many thanks

On Text Box Key Press event procedure write

if Not Instr(1,"1234567890",chr$(KeyAscii,0) > 0 or KeyAscii = 8) then
KeyAscii=0

I am not sure the NumericUpDown list is what I am looking for,

as what I have is a simple Textbox, and I just want to ensure that only
numbers are entered, (later they are picked up by a formula)

on further research i have found
TextBox1.Numeric = true

for VB

so maybe there is an equivalent for VB .net?

I would not prvent the user from entering non-numeric characters.
Instead I would add validation code to its 'Validating' event handler
and use an ErrorProvider to make the user aware of wrong input.
