Question

我有一个在这里启用和禁用按钮的方法。我输入一个数字时应该执行if-else阻止lbDivide 'öde'，'0'和'00' 按钮应处于活动状态，但只能激活 öde 按钮。我该怎样解决这个问题？

öde=付款


KişiSayısı=有多少人？

private void Bol_Click(object sender, RoutedEventArgs e)
    {
        lbDivide.Text = "0";
        btnBol.Opacity = 0.5;
        btnBol.IsEnabled = false;
        lbPayment.Visibility = Visibility.Hidden;

        if (lbDivide.Text == "0")
        {
            btnQr.Opacity = 0.5;
            btnQr.IsEnabled = false;
            zero.Opacity = 0.2;
            zero.IsEnabled = false;
            double_zero.IsEnabled = false;
            double_zero.Opacity = 0.2;
        }
        else
        {
            btnQr.Opacity = 1;
            btnQr.IsEnabled = true;
            zero.Opacity = 1;
            double_zero.Opacity = 1;
            zero.IsEnabled = true;
            double_zero.IsEnabled = true;
        }

Answer 1

我想我知道错误在哪里。

private void Bol_Click(object sender, RoutedEventArgs e)
{
    lbDivide.Text = "0";   /// in this line of code you're basically setting lbDivide.text to be 0 every time the button is clicked, so the else condition will never be met.
    btnBol.Opacity = 0.5;
    btnBol.IsEnabled = false;   /// you're basically disabling the button after the first click.
    lbPayment.Visibility = Visibility.Hidden;

    if (lbDivide.Text == "0")
    {
        btnQr.Opacity = 0.5;
        btnQr.IsEnabled = false;
        zero.Opacity = 0.2;
        zero.IsEnabled = false;
        double_zero.IsEnabled = false;
        double_zero.Opacity = 0.2;
    }
    else
    {
        btnQr.Opacity = 1;
        btnQr.IsEnabled = true;
        zero.Opacity = 1;
        double_zero.Opacity = 1;
        zero.IsEnabled = true;
        double_zero.IsEnabled = true;
    }
}

Answer 2

if（lbDivide.Text ==＆＃34; 0＆＃34;）改变if（lbDivide.Text.Equals（＆＃34; 0＆＃34;））

Wpf按钮IsEnabled无法正常工作
