wpf?
yes
handle
PreviewTextInput and validate
set eventArgs.Handled to true if its not validso i had this
PreviewKeyDown="TextBox_PreviewKeyDown" then i just write some code in the method in order to select only the key i want. That it ?no
PreviewTextInput not KeyDown
then you check if the text is valid, in your case if its a decimal numberaww ok cause preview key check only the last key pressed instead of the whole text
i will look some regex expression or something like this thanks i didn't know there was preview event
sure
you can also use
TryParsei will do that once i've make sure that my string is a decimal 🙂
you can use that to check if its a decmial
oohhhh i thought it just convert my number from string to double or others
also returns whether it can be converted or not
insane 😮 now i just need to avoid multple dot
thanks a lot you give me all the int i needed
np
