Answer 1

您可以定义进度条＆amp;的ValueChanged事件。将值设置为弹出窗口。请参考以下示例：

//Define a popup in your code, add a Label to it; the below code could be added to the 
//ctor/any other block which would be invoked prior to the ValueChanged event. 
//Please ensure Popup is declared such that it is visble/accessible in any of the 
//functions - in this case, the ValueChanged Event & where you decide to add label & 
//placement values to it.

Popup pop = new Popup();
Label lbl = new Label();
pop.Child = lbl;
pop.Placement = placementMode.Relative;
pop.PlacementTarget = progressBar;//assuming name of ProgressBar is progressbar

private void ProgressBar_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
{
    pop.IsOpen = true;
    //Set the horizontal offset of Popup in accordance to dimensions of your progress bar
    (pop.Child as Label).Content = progressBar.Value.ToString();
    Thread.Sleep(100);
    pop.IsOpen = false;
}

注意：如果你需要弹出式外观​​＆amp;根据您的屏幕截图，您必须修改标签的模板。
