private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (!(Char.IsLetterOrDigit(e.KeyChar) == true ||(e.KeyChar)==8))
{
e.cancel = true;
}
}
i tried the above code for my alphanumeric filter as a textbox
it is giving me the following error.:
its saying :
--->System.Windows.Forms.KeyPressEventArgs' does not contain a definition for 'cancel' <-----
help!
how can i get it to work
my main aim is to only let the user type alphanumeric strings into teh textfield.

Just remember that C# is case sensitive - lol
Try: e.Cancel

I know it old but i managed to find this forum while search and the answer is...
e.Handled = true;
but you might want to put a MessageBox there too, as there is no warning it just doesn't type anything

Hey Ankur,
Actually i do not have a .NET installed box right nw at my disposal(hence no intellisense :-)) hence all the code i am putting is from my head. I beleive there are two more events to handle the keyboard events like keyDown, keyUp. Why don't u try playing around with them, u'll surely get a solution else whenever i get my hand on a .NET installed box i'll be able to help u.

yeah tried it myself also before this thread.. it doesnt stop the non alphanumeric to be printed into the text box. so was curious if i was doing it right.
anyhow. thanks..
regards,
Ankur
PS: i will try someother way to stop those darn non-alpha chars to be typed.
