一个类似于Windows复制和粘贴功能的弹出框 [英] A pop-up box similar to the windows copy and paste function

问题描述

Wpf MVVM模型开发

1. UI一个ProgressControl.xaml，用于弹出进度条窗口文件，主要内容如下：

Wpf MVVM model development
1. UI a ProgressControl.xaml, for the pop-up progress bar window file, the following major elements:

<StackPanel>

        <TextBlock  Text="{Binding Caption}"  Style="{StaticResource CaptionText}"/>
        <Border Style="{StaticResource ContentBorder}">
            <StackPanel>
                <StackPanel Style="{StaticResource ContentMessageBorder}">
                    <TextBlock   Text="{Binding Message}" Style="{StaticResource ContentMessage}" />
                    <telerik:RadProgressBar  Minimum="0" Maximum="100" Margin="10,10,10,0"

                     Width="260" Height="25"  Value="{Binding Value}" Visibility="Visible" />
                </StackPanel>
                <StackPanel  Style="{StaticResource ButtonContainer}">
                    <telerik:RadButton Command="{Binding CancelCommand}" Content="{Resx CancelBtnText}" IsCancel="True"  />
                </StackPanel>
            </StackPanel>
        </Border>
    </StackPanel>

对应的VM属性：

Corresponding VM attributes:

bool IsHidden { set; }
string Caption { get; set; }
bool IsVisible { get; set; }
string Message { get; set; }
int Value { get; set; }
ICommand CancelCommand { get; }

2.我在另一台虚拟机中导出图像和弹出进度条，主要代码如下：

2. I export images and pop-up progress bar in another VM, the main code is as follows:

_progressVM.IsVisible = true;
 _progressVM.Caption = "Exporting";

if (modeIndex == "1")
                    {
                        var navImages = NavBarSelectedDocument.DocumentImagesUC_VM.Images.Where(x => x.IsDefaultImage == false).ToList();
                        if (!isExportSplitPage)
                        {
                            navImages = NavBarSelectedDocument.DocumentImagesUC_VM.Images.Where(x => x.IsDefaultImage == false && x.IsSplitPage == false).ToList();
                        }
                        int i = 0;
                        int count = navImages.Count;
                        foreach (var item in navImages)
                        {
                            i++;
                            _progressVM.Message = item.LinkedDocument.Name + "--" + item.Image.Name;
                            _progressVM.Value = ((i * 100) / count);
                            _project.ExportDocument(item.ImagePath, exportPath, item.LinkedDocument.Name, item.Name);
                        }
                    }

_progressVM.IsVisible = false;

上面的代码可以弹出一个很好的进度条窗口，但我现在要取消该功能，即弹出窗口中有一个Cancel按钮，单击取消，弹出窗口关闭，并停止导出图片。我设置正在进行取消按钮绑定命令IsVisible = false，但是不起作用，编辑的注意啊？为了实现这个功能我需要做些什么，追求大神帮助，非常感谢

The code above can be a good progress bar window pops up, but I now want to cancel the function, that is, there is a Cancel button in the pop-up window, click Cancel, the pop-up window is closed, and stop the export picture. I set up in progress Cancel button bindings command IsVisible = false, but does not work, Editor''s Note ah? What do I have to do in order to achieve this functionality, pursuing big God help, thank you very much

推荐答案

尝试使用Thread来执行中止正在运行的导出

Try to use Thread to execute an abort the running export

private System.Threading.Thread thread = new System.Threading.Thread(Export);
private void Export(){
_progressVM.IsVisible = true;
 _progressVM.Caption = "Exporting";
 
if (modeIndex == "1")
                    {
                        var navImages = NavBarSelectedDocument.DocumentImagesUC_VM.Images.Where(x => x.IsDefaultImage == false).ToList();
                        if (!isExportSplitPage)
                        {
                            navImages = NavBarSelectedDocument.DocumentImagesUC_VM.Images.Where(x => x.IsDefaultImage == false && x.IsSplitPage == false).ToList();
                        }
                        int i = 0;
                        int count = navImages.Count;
                        foreach (var item in navImages)
                        {
                            i++;
                            _progressVM.Message = item.LinkedDocument.Name + "--" + item.Image.Name;
                            _progressVM.Value = ((i * 100) / count);
                            _project.ExportDocument(item.ImagePath, exportPath, item.LinkedDocument.Name, item.Name);
                        }
                    }
 
_progressVM.IsVisible = false;
}

点击导出按钮，请致电：

On click Export button, please call:

thread.Start();

点击取消按钮，请致电：

And on Cancel button click, call:

if (thread.IsAlive || thread.IsBackground)
{
   thread.Abort();
}
