重新加载PhoneApplicationPage [英] Reloading a PhoneApplicationPage

问题描述

我正在使用silveright进行Windows Phone的应用程序，有时我需要重新加载屏幕上显示的同一页面。我正在使用PhoneApplicationPage类来构建我的页面。

Hi, I'm doing an application for windows Phone with silveright, and i need to, sometimes, reload the same page shown on screen. I'm Using the PhoneApplicationPage class to build my pages.

我有一个必须刷新同一页面的按钮，名为page6，所以当我点击它时我会调用一个应该按下的按钮事件刷新页面。有谁知道怎么做？

I have a button the must refresh the same page, named page6, so when i click it i call a button event that should refresh the page. Does anyone knows how to do it?

我已经尝试过这个：

NavigationService.Source = new Uri("/Page6.xaml", UriKind.Relative);//or this
NavigationService.Navigate(NavigationService.Source);//or this
Navigate(NavigationService.CurrentSource);

 

 

推荐答案

static int refreshCount;
 
void Button_Click(object sender, RoutedEventArgs e)
{
	Debug.WriteLine(NavigationService.Source);
	string url = NavigationService.Source.ToString();
 
	if (!url.Contains("RefreshCount="))
	{
		if (NavigationContext.QueryString.Count < 1)
		{
			url += "?RefreshCount=" + ++refreshCount;
		}
		else
		{
			url += "&RefreshCount=" + ++refreshCount;
		}
	}
	else
	{
		url = Regex.Replace(url, @"RefreshCount=+\d", "RefreshCount=" + ++refreshCount);
	}
	NavigationService.Navigate(new Uri(url, UriKind.Relative));
}
