Disabling swipe gesture in Windows Phone 8.1 pivot control

问题

I am making a Universal app. For the windows phone part I have implemented a pivot page in it. Now I want the swipe gesture (for navigating through different pivot items) in pivot page to be disabled so that only when a button on the first PivotItem is tapped then it shows the second PivotItem. I tried setting the IsHitTestVisible property of the Pivot control to false but then all the PivotItem are blocked.

It goes against the WINDOWS UI Guide and shouldn't really be implemented.

However, for the sake of theory if nothing else, you could do something like this.

Consider you have 5 pivot items, give your first and last PivotItem a name as

<controls:PivotItem Header="Item1" Name="first">
...

 <controls:PivotItem Header="Item5" Name="last">

Handle the Pivot's LoadingPivotItem and LoadedPivotItem events. You can then do something like this:

//class level variable we use for the current pivot
PivotItem currentItem = null;

private void Pivot_LoadingPivotItem(object sender, PivotItemEventArgs e)
{
//if the next item is going to be "first" pivot
//and the previous item was the "last" pivot...
if (e.Item == first && currentItem == last)
{
  //...reset the Pivot back to the last one.
   mainPivot.SelectedItem = last;
}

//same theory as above but checking if we're 
//sliding to the last one from the first one
if (e.Item == last && currentItem == first)
{
   mainPivot.SelectedItem = first;
}
}

private void mainPivot_LoadedPivotItem(object sender, PivotItemEventArgs e)
{
 //once the pivot is loaded, update the currentItem
 currentItem = e.Item;
}

Hope this works.. For any queries .. revert back.
