I have gone through the thread:
binding two VerticalScrollBars one to another
it has almost helped to achieve the goal but still there is something missing. It is that moving the scrollbars left-right or up-down gives expected behavior of scrolling in both of my scrollviewers but when we try to scroll using/clicking arrow buttons at the ends of these scrollbars in scrollviewers only one scrollviewer is scrolled which is not the expected behavior.
So what else we need to add/edit to solve this?
One way to do this is using the ScrollChanged
event to update the other ScrollViewer
<ScrollViewer Name="sv1" Height="100"
HorizontalScrollBarVisibility="Auto"
ScrollChanged="ScrollChanged">
<Grid Height="1000" Width="1000" Background="Green" />
</ScrollViewer>
<ScrollViewer Name="sv2" Height="100"
HorizontalScrollBarVisibility="Auto"
ScrollChanged="ScrollChanged">
<Grid Height="1000" Width="1000" Background="Blue" />
</ScrollViewer>
private void ScrollChanged(object sender, ScrollChangedEventArgs e)
{
if (sender == sv1)
{
sv2.ScrollToVerticalOffset(e.VerticalOffset);
sv2.ScrollToHorizontalOffset(e.HorizontalOffset);
}
else
{
sv1.ScrollToVerticalOffset(e.VerticalOffset);
sv1.ScrollToHorizontalOffset(e.HorizontalOffset);
}
}
