推荐答案
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Button Name="BStart" Content="Start" Width="100" Height="50" HorizontalAlignment="Left" Click="BStart_Click" />
<Button Name="BCapture" Content="Capture" Width="100" Height="50" HorizontalAlignment="Right" IsEnabled="False" />
</Grid>
</Window>
您可以通过 xaml 禁用捕获,然后通过在 c# 中编写代码启用它.
you can disable Capture by xaml and then enable it by writing code in c#.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WpfApplication1
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void BStart_Click(object sender, RoutedEventArgs e)
{
BStart.IsEnabled = false;
BCapture.IsEnabled = true;
}
}
}
启用和禁用使用 IsEnabled 属性.并点击按钮使用 Click 事件.
for enable and disable use IsEnabled Property. and for clicking on the button use Click event.
