private void textBox1_PreviewTextInput(object sender, TextCompositionEventArgs e)
{
if (!char.IsDigit(e.Text, e.Text.Length - 1))
{
e.Handled = true;
}
}
for wf:
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
{
if (!char.IsDigit(e.KeyChar) )
{ e.Handled = true;
} } }
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
e.Handled = !Char.IsDigit(e.KeyCode);
}
