You have a very large report that need to be displayed. After some time it's displayed, but the cursor moves very slow. What can cause a problem?
could assume that the problem is related with the fact that custom cursor is used and it is being redrawn for a long time. You may think that it's strange because
you didn't use some custom cursors but they are used by default.
In order to make the cursor moving faster you need to use the following easy code:
reportViewer.CustomCursorsUsing = false;
