I have lot of textbox in my winform. maybe 20 to 30 textbox. and I need all texbox have numerical only when typing.
I use keypress event per textbox to handle the numerical only(code below)
if (!char.IsControl(e.KeyChar) && !char.IsDigit(e.KeyChar) && (e.KeyChar != '.'))
{
e.Handled = true;
}
// only allow one decimal point
if ((e.KeyChar == '.') && ((sender as TextBox).Text.IndexOf('.') > -1))
{
e.Handled = true;
}
is there possible way to inherit all textboxes in just 1 keypress event?
Implement the keypress event for only one textbox.
Then select another text box and go to keypress event and select the method you already implemented.
