As the documentation says, the Offset properties set the position relative to the application window:
Gets or sets the distance between the left side of the application
window and the left side of the popup.
This means, that the position is set in absolute relative to the window and will not update automatically when the GridView is scrolled. Instead, you will have to update it manually by observing the scroll viewer events. First use the VisualTreeHelper to find ScrollView inside the GridView:
public static ScrollViewer FindScrollViewer(DependencyObject d)
{
if (d is ScrollViewer) return d as ScrollViewer;
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(d); i++)
{
var child = VisualTreeHelper.GetChild(d, i);
var result = FindScrollViewer(child);
if (result != null) return result;
}
return null;
}
You can use this helper method like this:
var scrollViewer = FindScrollViewer(MyGridView);
And now attach the scrollViewer.ViewChanged or scrollViewer.ViewChanging event and update the popup position as you see fit.
