Pass that index value as query string and then update the pivot.selectedindex value in onNNavigatedTo function

blocks|key|632879|text|您应该能够在OnNavigatedTo方法中设置piviot的选定索引。也可以看看http://christian-helle.blogspot.co.uk/2011/02/working-around-pivot-selectedindex.html。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|632880|entityMap|0|LINK|mutability|MUTABLE|url|http://christian-helle.blogspot.co.uk/2011/02/working-around-pivot-selectedindex.html^0|15|2D|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

You should be able to set the selected index of the piviot in the OnNavigatedTo method.

<pre><code>public enum PivotDef

public static PivotDef SelectedPivot;

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)

blocks|key|2536882|text|这是为您提供的解决方案。只需将以下代码添加到目标页面：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2536883|protected+override+void+OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs+e)

++++if+(NavigationContext.QueryString.ContainsKey("PivotNada.SelectedIndex"))

Here is a solution for you. Just add the following code to destination page:

<pre><code>protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
 if (NavigationContext.QueryString.ContainsKey("PivotNada.SelectedIndex"))
 {
 int selectedIndex = -1;
 if(int.TryParse(NavigationContext.QueryString["PivotNada.SelectedIndex"].ToString(), out selectedIndex))
 {
 if(selectedIndex != -1)
 {
 pivot.SelectedIndex = selectedIndex;
 }
 }
 }
}
</code></pre>

blocks|key|632925|text|protected+override+void+OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs+e)
{
++string+strItemIndex;
++if+(NavigationContext.QueryString.TryGetValue("goto",+out+strItemIndex))
++{
++++myPivot0.SelectedIndex+=+Convert.ToInt32(strItemIndex);
++}
++base.OnNavigatedTo(e);
}|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|632926|请注意，myPivot0是枢轴的名称(根据枢轴名称进行更改)。然后，导航：|unstyled|offset|length|style|CODE|632927|NavigationService.Navigate(new+Uri("/ContactP.xaml?goto=0",+UriKind.RelativeOrAbsolute));|632928|其中ContactP.xaml包含枢轴。|632929|entityMap^0|0|4|8|0|0|2|D|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$B|C]]|$1|D|3|E|5|F|7|R|8|@$G|S|H|T|I|J]]|9|@]|A|$]]|$1|K|3|L|5|6|7|U|8|@]|9|@]|A|$B|C]]|$1|M|3|N|5|F|7|V|8|@$G|W|H|X|I|J]]|9|@]|A|$]]|$1|O|3|-4|5|F|7|Y|8|@]|9|@]|A|$]]]|P|$]]

<pre><code>protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
 string strItemIndex;
 if (NavigationContext.QueryString.TryGetValue("goto", out strItemIndex))
 {
 myPivot0.SelectedIndex = Convert.ToInt32(strItemIndex);
 }
 base.OnNavigatedTo(e);
}
</code></pre>

Note that <code>myPivot0</code> is the name of your pivot (change it based on your pivot name). Then, navigate:

<pre><code>NavigationService.Navigate(new Uri("/ContactP.xaml?goto=0", UriKind.RelativeOrAbsolute));
</code></pre>

where <code>ContactP.xaml</code> contains the pivots.

I try this code to navigate to pivotitem in another page, but it's still not work

<pre><code>private void Nada1_Click(object sender, RoutedEventArgs e)
 {
 NavigationService.Navigate(new Uri("/Nada.xaml?PivotNada.SelectedIndex=0", UriKind.Relative));
 }
</code></pre>

Can anyone help me ?
