i have a grid (virtual) with about 100 rows, when the user clicks a separate check box i go thro and hide certain rows( about 90%) based on a cell content. this is fine but when i go thro and unhide those rows the vertical scroll bar fails to come back. Even if i set the scroll bar to display it is not enabled

After hiding the rows, try calling grid.Refresh() to see if that makes the scrollbar appear properly.

Attached is little sample with a button that hides rows in a virtual grid. The scrollbar seems to work as expected for me using version 3.3. What are you doing differently? Can you upload a sample showing the problem?

The RowHiddenEntries collection is used at design time and not really intended for use at run time. To reset the hidden rows at runtime, use code like: this.gridControl1.Rows.Hidden.ResetRange(1, this.gridControl1.RowCount);
