Accepted answer
Please share the complete xaml and in c# code also, I feel you should put braces for IF condition. It would give clear picture on what is happenning

@tnx swetha everything working fine....tnx alot

c# code:
private void ScrollViewer_PreviewMouseWheel(object sender, MouseWheelEventArgs e)
{
if (Keyboard.IsKeyDown(Key.LeftShift) || Keyboard.IsKeyDown(Key.RightShift))
{
if (e.Delta > 0)
scrollviewer.PageLeft();
else
scrollviewer.PageRight();
e.Handled = true;
}}

xaml code: Must use this line

Note :
1st open a xaml to write the scrollviewer code
CODE:
PreviewMouseWheel = " Event Name "> .. and click the event PreviewMouseWheel. every thing goes under the scroll viewer.
2nd write ur code on C#.
