C# 等待框

今天发现dev控件自带了等待框，调用方便，而且不会阻塞主线程。

拉一个窗体，界面上放两个按钮，显示等待框，隐藏。

<Window x:Class="WaitDialogTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WaitDialogTest"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <Button Content="显示等待框" HorizontalAlignment="Left" Margin="258,122,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click"/>
        <Button Content="隐藏" HorizontalAlignment="Left" Margin="464,122,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click_1"/>

    </Grid>
</Window>

后台写代码测试看看

    public partial class MainWindow : Window
    {
        DevExpress.Utils.WaitDialogForm frm;
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            frm = new DevExpress.Utils.WaitDialogForm("请稍后......","正在加载数据");
            frm.Visible = true;
            
        }

        private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            frm.Visible = false;
        }
    }
