Basic usage

<Border x:Class="HandyControlDemo.UserControl.TextDialog"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:hc="https://handyorg.github.io/handycontrol"
        CornerRadius="10"
        Width="400"
        Height="247"
        Background="{DynamicResource RegionBrush}">
    <hc:SimplePanel>
        <TextBlock Style="{StaticResource TextBlockLargeBold}" Text="Please Wait"/>
        <Button Width="22" Height="22" Command="hc:ControlCommands.Close" Style="{StaticResource ButtonIcon}" Foreground="{DynamicResource PrimaryBrush}" hc:IconElement.Geometry="{StaticResource ErrorGeometry}" Padding="0" HorizontalAlignment="Right" VerticalAlignment="Top" Margin="0,4,4,0"/>    
    </hc:SimplePanel>
</Border>

namespace HandyControlDemo.UserControl
{
    public partial class TextDialog
    {
        public TextDialog()
        {
            InitializeComponent();
        }
    }
}

Dialog.Show(new TextDialog());

Asynchronously wait for the result to return

After initializing the vm through the Initialize extension method, you can use the GetResultAsync method to achieve asynchronous wait on this basis:

Dialog.Show<InteractiveDialog>()
    .Initialize<InteractiveDialogViewModel>(vm => vm.Message = DialogResult)
    .GetResultAsync<string>()
    .ContinueWith(str => DialogResult = str.Result);

A simpler asynchronous way

var d = Dialog.Show<ProgressDialog>();
await Task.Delay(5 * 1000);
d.Close();

Pop-up behavior

If the token parameter is not given when calling the Show method, it will pop up the currently active window by default. If the value of token is given, the type of the target element will be judged internally. If the type is a window, it will pop up in the decoration layer under the window, otherwise it will look for the child elements of the target element until it finds the type of DialogContainer The child element of will finally pop up inside the child element.

<UserControl hc:Dialog.Token="DialogContainer">
    <hc:DialogContainer>
        // Internal controls
    </hc:DialogContainer>
</UserControl>
