[@randomhappyguy6719]

.Net has upgraded and int representation of characters are no longer needed. We can use code like this:
char ch = e.KeyChar;
if (!char.IsDigit(ch) &&
ch != Convert.ToChar(Keys.Back) &&
ch != Convert.ToChar(Keys.Delete))
e.Handled = true;
Here we use a Convert.ToChar(Object object) to directly convert a Keys enumeration variable to a character, then compare.

i cant found your Remaining lectures of this course in this Channel. what i do? please give me link of complt tutorial of this course. Thanks

[@oblivionX000]

Is that possible with decimals as well? Cause I would try to input a period for the decimal which then the code prevents me from doing so.

[@Verses01]

Awesome Thank you!!!

[@CalebRussell1]

You helped me so much. Thank you bhai

[@MonderMurshed]

THANK U BRO!

[@amazingbandproyects3253]

Works : ) ..Thank you so much.....Regards from Costa Rica : )

[@yameen_yasin]

thankew sir aap explane bhi ache krte ho or kaam to hota he aap k acha hai

[@ZCProductions211]

If Anyone is wondering how to make it possible to enter a period like 1.70 then add
&& ch != 46 to the if statement after the ch != 8. I had to do this for the program i am making.

[@filipMmM]

thank you :)

[@krolik3524]

Thank you.

[@funtaro]

Thanks, it's help me alot

[@MrFerny82]

Hi, your tutorial is great but i'm running into an issue and I want to use number an at the end the character -, how to i do that? my example should look like this only 102030-10
Thanks

[@rodrigo-vl7bi]

thanks for showing this solution, but im sure there must be a simplier way, al keep looking for it

[@LivinExtreme]

what if I paste it doesn't work then

[@adrianm.4873]

Thank you!

[@brv0102]

thanks, bro!

[@intelligentcoding689]

Amazing. thanks

[@hafizullahmutahidi264]

Thank You So So Much

[@MegaMaliak]

Hi how do i make validation to allow format like prices ONLY? 999.99 is the precise amount i need. Nothing more than that, but can't go below 0.

[@3dwinarcip394]

Niceee❤❤❤ Thanks

[@atquoc9071]

Thanks for video

[@shovikanand3214]

very knowledgeful video....but i want to add more concept in this, here e is object of keypressEventArgs Class. & this class has 2 properties namely keychar & handled. keychar gives u key pressed by user. & handled doesnt allows wrong entry into textboxes. here char is structures. & Isdigit, Isletter, IsDigitorLetter,Issymbol .....are its properties..
hence we use , char.Isdigit(e.keychar) & similary e.handled= true; restrict wrong entry & e.handled= false; to allow entry in textbox. hope u get benifited after reading this...

[@muhdzikrie8682]

thanks

[@vihangasilva]

Thank you

[@YukthiJayakody]

Thanks a lot....

[@mikaillim9978]

hii.. why you can using DateTimePicker ? it simple :D

[@user-xg7hi5mh3g]

Thnak u for your video its great i just have a small isssue with this filtraion how can we for example just allow numbers between 0 and 13 ?

thank you soooooooo much

[@TheTrueKailash]

thank you

[@prodbyfys]

Thanks Bro

[@girishbawaskar3775]

and if i want only char than ?????

[@deano2187]

Thank you senpai

[@ariii39]

Thanks!!!!

[@malthesrensen4953]

Seems wierd that this isen't in the library already. When pasting, you can still add text to the field for example, so that has to be fixed aswell. Seems like a lot of work for something that should've been in the library already

[@IAmESG]

Or this:
if (System.Text.RegularExpressions.Regex.IsMatch(tb11.Text, "[^0-9-]")) // only accepts 0-9 and negative
{
MessageBox.Show("Please enter numbers only!");
tb11.Clear();
}

[@thifhelimbilu2477]

Thanks For that code it helps me :)

[@dennisJNT]

nice man..

[@Soundtech98]

Still doesn't prevent the user from pasting directly into the text box...

[@gnscode7988]

helpfull

[@idsoftware7]

how about decimals ?

[@kmuralikrishna1582]

if we want combination of numbers and string ?

[@kristiancagaoan2223]

THANKS BRUH

[@claytonvolner5950]

Great video. Thanks for the help

[@iiN1GH7M4R3ii]

thank youuuuu

[@angelodeus8423]

[@thiagosarraf7265]

where are you from? I'm brazilian

[@wunnathaw]

that is cool..but I input 012 or 1.11 .It cannot validate .

[@jobijose8354]

this is not an validation process infact we can block some sort of data thats all

[@sheetalvishwakarma2697]

Voice is not auditable

[@bluehornet6752]

Here's a routine that's worked well for me...
private void CharValidation_KeyDown(object sender, KeyEventArgs e)
{
// Rejects any keys not in the range of 0-9 (by ASCII number),
// the Delete key or the Back key
if ((e.KeyValue < 48 || e.KeyValue > 57) && e.KeyCode != Keys.Delete
&& e.KeyCode != Keys.Back
{
e.SuppressKeyPress = true;
SystemSounds.Beep.Play();
}
}

[@Volln0v]

This works, but not if a user used the num pad. This is what I used for my program, it's kind of lengthy but it allowed for numpad decimal, period, numlock, and arrow keys. Probably not the most efficient way, but it works.
if ((e.KeyValue < 48 || e.KeyValue > 57) && e.KeyCode != Keys.OemPeriod && e.KeyCode != Keys.NumLock && e.KeyCode != Keys.Decimal && e.KeyCode != Keys.Delete
&& e.KeyCode != Keys.Back && e.KeyCode != Keys.NumPad0 && e.KeyCode != Keys.NumPad1 && e.KeyCode != Keys.NumPad2 && e.KeyCode != Keys.NumPad3 && e.KeyCode != Keys.NumPad4 && e.KeyCode != Keys.NumPad5 && e.KeyCode != Keys.NumPad6 && e.KeyCode != Keys.NumPad7 && e.KeyCode != Keys.NumPad8 && e.KeyCode != Keys.NumPad9 && e.KeyCode != Keys.Left && e.KeyCode != Keys.Right)
{
e.SuppressKeyPress = true;
SystemSounds.Beep.Play();
}
