Hi guys!
I would like to know if there is any way to accept only numbers with two decimal places (example: 123.55) only on my text boxes. I have not yet tried any code but what I have searched is using the masked text box. But I do not like to use it due to the fact that I do not know about it :) anyone can help me? Thanks in advance!

So you are lazy, and we are supposed to take care of you ?

1 solution

Writre code textbox keypress event like Below

C#
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
    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;
    }
}
