Im using the toolkit GestureService.GestureListener, the implementation is going very well.
The main page contains a LongListSelector, and on the top (not visible to the user) I have my sliding menu that I slide using the GestureService.
when I try to scroll in the LongListSelector the menu on the top comes down, which is not good.
if im scrolling on the list don't slide the menu, other than that, slide the menu !
how to handle such an event.
thanks
Edit
<Grid x:Name="LayoutRoot">
<toolkit:GestureService.GestureListener>
<toolkit:GestureListener DragDelta="GestureListener_DragDelta"
DragCompleted="GestureListener_DragCompleted" />
</toolkit:GestureService.GestureListener>
<phone:Panorama Foreground="Black">
<phone:PanoramaItem>
<Phone:LongListSelector x:Name="MyList"
ItemTemplate="{StaticResource MyListTemplate}"/>
</phone:PanoramaItem>
<phone:PanoramaItem>
</phone:PanoramaItem>
</phone:Panorama >
</Grid>
And this is my C# Code
private void CloseSettings()
{
var trans = _feContainer.GetVerticalOffset().Transform;
trans.Animate(trans.Y, 0, TranslateTransform.YProperty, 500, 0, new CubicEase //trans.Y, 0, TranslateTransform.YProperty, 120, 0, new CubicEase
{
EasingMode = EasingMode.EaseOut
});
_isSettingsOpen = false;
}
private void OpenSettings()
{
var trans = _feContainer.GetVerticalOffset().Transform;
trans.Animate(trans.Y, 400, TranslateTransform.YProperty, 200, 0, new CubicEase
{
EasingMode = EasingMode.EaseInOut
});
_isSettingsOpen = true;
}
private void ResetLayoutRoot()
{
if (!_isSettingsOpen)
_feContainer.SetVerticalOffset(0.0);
else
_feContainer.SetVerticalOffset(120.0);
}
private void GestureListener_DragDelta(object sender, DragDeltaGestureEventArgs e)
{
if (e.Direction == System.Windows.Controls.Orientation.Vertical && e.VerticalChange > 0 && !_isSettingsOpen)
{
double offset = _feContainer.GetVerticalOffset().Value + e.VerticalChange;
if (offset > _dragDistanceToOpen)
this.OpenSettings();
else
_feContainer.SetVerticalOffset(offset);
}
if (e.Direction == System.Windows.Controls.Orientation.Vertical && e.VerticalChange < 0 && _isSettingsOpen)
{
double offsetContainer = _feContainer.GetVerticalOffset().Value + e.VerticalChange;
if (offsetContainer < _dragDistanceToClose)
this.CloseSettings();
else
_feContainer.SetVerticalOffset(offsetContainer);
}
}
private void GestureListener_DragCompleted(object sender, DragCompletedGestureEventArgs e)
{
if (e.Direction == System.Windows.Controls.Orientation.Vertical && e.VerticalChange > 0 && !_isSettingsOpen)
{
if (e.VerticalChange < _dragDistanceToOpen)
this.ResetLayoutRoot();
else
this.OpenSettings();
}
if (e.Direction == System.Windows.Controls.Orientation.Vertical && e.HorizontalChange < 0 && _isSettingsOpen)
{
if (e.VerticalChange > _dragDistanceNegative)
this.ResetLayoutRoot();
else
this.CloseSettings();
}
}
Variables declared in the class, its working really good, but as i said before, when I scroll in my longListSelector, the menu slides down, i dont want that !
