you have set variableRowHeight="true" , in this case its not possible to make scrollbar consistent. The height will vary with the changing height of the content, other wise the content will scroll partially. In dataGrid and Listcontrol the data is added when we scrollup and down so when we scroll row is added and removed ,the component does not know itself that whats exact height would be before adding the new row, in fixed height its predefined .

@ Davis,
thanks for your reply,
But, this should not be the case.
Can we have any work around for this problem...

I tried to find some work around but, it seems technically its not possible, unless we have fixed height of content, since content is populated dynamically in dataGrid and List due to performance improvement
