C# how to put comma for a dicimal in textbox?????

Accepted answer

the best way is allow only nomber, in behind code when you wanted to display this as in currency just convert that nomber into currency format and display.

hi,

it is not the best way giving coma(,) to enter by user in decimal field they can enter like more than one coma

for example,

5,300 correct

15,55,300 may be correct based on currency as per your country

12,,3,5 this is totally wrong

so dont allow any thing apart from nomber if you wanted to allow dot(.) then allow only one.

change this

if (char.IsNumber(e.KeyChar))

to

if (char.IsNumber(e.KeyChar) || e.KeyChar == ',')

so that it will accept comma as well
