I have a gridview which has 4,100 rows and 30 columns. If I scroll the grid to the right (in other words so I can see columns 18 thru 30) and then choose to filter on one of those columns, the default filter dialog pops up as expected. However as soon as I select a value in the pop-up dialog the grid immediately scrolls to the left, the dialog stays visible but 'empties'. I then scroll the grid to the right and the filter has been applied as expected. If I filter on a column that is visible initially (i.e. columns 1 thru 17) then this problem does not exist, Is this behavior by design and if so how do I turn it off or if it is a problem is their a work around or fix available. Please advise - thanks
