C# 等待框

今天發現dev控件自帶了等待框，調用方便，而且不會阻塞主線程。

 

拉一個窗體，界面上放兩個按鈕，顯示等待框，隱藏。

<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="顯示等待框" HorizontalAlignment="Left" Margin="258,122,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click"/>
        <Button Content="隱藏" HorizontalAlignment="Left" Margin="464,122,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click_1"/>

    </Grid>
</Window>

后台寫代碼測試看看

    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("請稍后......","正在加載數據");
            frm.Visible = true;
            
        }

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