如何导航到 Windows Phone 中的某个 Pivot 页面? [英] How can I navigate to a certain Pivot page in Windows Phone?

问题描述

我创建了一个带有两个链接的 MainPage.两者都会将用户带到一个新的 Pivot 页面.但是，第一个链接将打开 Pivot 的第一页，而第二个链接将打开 Pivot 的第二页.

I have created a MainPage with two links. Both will take the user to a new Pivot page. However, the first link will open the first page of the Pivot, while the second will open the second page of the Pivot.

到目前为止我有以下代码:

I have the following code so far:

主页:

NavigationService.Navigate(new Uri("/PivotTester.xaml?goto=" + i, UriKind.Relative));

然后在 PivotTester 页面上:

and then on PivotTester page:

namespace CelticNow
{
public partial class PivotTester : PhoneApplicationPage
{
    PivotTester pivot = new PivotTester();

    public PivotTester()
    {
        InitializeComponent();
    }

    protected override void OnNavigatedTo(NavigationEventArgs e)
    {
        string strItemIndex;
        if (NavigationContext.QueryString.TryGetValue("goto", out strItemIndex))
            pivot.SelectedIndex = Convert.ToInt32(strItemIndex);

        base.OnNavigatedTo(e);
    }
}
}

我添加了Pivot pivot = new..."，因为使用 PivotTester.SelectedIndex 不起作用.

I added in the "Pivot pivot = new..." as using PivotTester.SelectedIndex wouldn't work.

任何人都可以提供有关我如何进行这项工作的解决方案吗?谢谢.

Can anyone provide a solution as to how I would make this work? Thanks.

//Remove if not necessary

 {
   string strItemIndex;
    if(NavigationContext.QueryString.Contains("goto"))

      pivotControl.SelectedIndex = Convert.ToInt32(strItemIndex);
