Numeric Data Entry in WPF

Question

How are you handling the entry of numeric values in WPF applications?

Without a NumericUpDown control, I\'ve been using a TextBox and handling its PreviewKeyDown eve

Answer 1

void PreviewTextInputHandler(object sender, TextCompositionEventArgs e)
{
    string sVal = e.Text;
    int val = 0;

    if (sVal != null && sVal.Length > 0)
    {
        if (int.TryParse(sVal, out val))
        {
            e.Handled = false;
        }
        else
        {
            e.Handled = true;
        }
    }
}
