I try this code to navigate to pivotitem in another page, but it's still not work
private void Nada1_Click(object sender, RoutedEventArgs e)
{
NavigationService.Navigate(new Uri("/Nada.xaml?PivotNada.SelectedIndex=0", UriKind.Relative));
}
Can anyone help me ?
Thanks before
I have described how i can be easily done here (sample project at http://wp7pivottest.codeplex.com ) http://invokeit.wordpress.com/2012/04/01/navigate-to-selected-pivot-item-wpdev-wp7dev/
public enum PivotDef
{
One,
Two,
Three,
Four,
}
public static PivotDef SelectedPivot;
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
switch (SelectedPivot)
{
case PivotDef.One:
this.pvtControl.SelectedItem = this.pvt1;
break;
case PivotDef.Two:
this.pvtControl.SelectedItem = this.pvt2;
break;
case PivotDef.Three:
this.pvtControl.SelectedItem = this.pvt3;
break;
case PivotDef.Four:
this.pvtControl.SelectedItem = this.pvt4;
break;
}
base.OnNavigatedTo(e);
}
Here is a solution for you. Just add the following code to destination page:
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;
}
}
}
}
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);
}
Note that myPivot0
is the name of your pivot (change it based on your pivot name). Then, navigate:
NavigationService.Navigate(new Uri("/ContactP.xaml?goto=0", UriKind.RelativeOrAbsolute));
where ContactP.xaml
contains the pivots.
将该索引值作为查询字符串传递,然后更新onNNavigatedTo函数中的ivot.selectedindex值
You should be able to set the selected index of the piviot in the OnNavigatedTo method. Have a look at http://christian-helle.blogspot.co.uk/2011/02/working-around-pivot-selectedindex.html too.
