a textbox only accept numeric value?

[ssfftt]

how can i make a textbox only accept numeric value? (e.g. integer, double or decimal)? is it possible to do it in design view? or i have to code it? To validate numeric value in coding before pass the value to further process is a pain for me, can anyone help plz?

lol, just learnt to use NumericUpDown control, for those new to vb.net, try it out, cheers

you can also make your own textbox that excepts whatever you want use user control that inherits textbox.

or if ya dont want to make a user control you could just the KeyPress event of the textbox and use the IsNumeric function to only allow numbers the dash (-) and the period (.)

but the numericupdown control is much more suited in this case

i dont think keypress will do the trick. what about paste???

 

[JuggaloBrotha]

if you use a boolean variable and set it in the keydown event you can use that in the keypress event to look for the ctrl + v, of course there's the context menu of the textbox too
