When I click on a cell to edit (CellClickAction="Edit"), the window position doesn't move, no scrolling occurs. Everything is just fine, except my row isn't selected so my style for the background color of the row doesn't work. I want to know why selecting the cell or editing the cell doesn't by definition select the row.
To get around this, I tried to use RowSelect. When I set the cell to select the row (CellClickAction="RowSelect"), the window scrolls to the top so I can't see the row that's been selected any more and editing the cell becomes an exerise in futility. Note that it's the actual window that is scrolled -- if I set a height on the Grid, the scroll position in that piece is maintained properly but the whole window is scrolled to the top. When I have 2 grids on a page, this is a serious problem and prevents editing.
This is with the newest package, using IE8. I want to know why editing the cell doesn't do the window scrolling thing, but selecting the row does. Obviously, selecting and editing the cell doesn't select the row (my first point), so what exactly happens on row selection that isn't happening on cell selection?
No matter what the cell mode, clicking on the row selector to select the row does exhibit this odd window scroll behavior.
Any help appreciated. I'm at my wits end with this control, it isn't doing anything I want it to do properly. Thanks!

Researching further, I see that if you add this handler
function UltraWebGrid1_AfterSelectChangeHandler(gridId, rowId){ var grid = igtbl_getGridById(gridId); var activeCell = grid.getActiveCell(); alert(activeCell);}
activeCell has a value after you click on a cell, but it is null if you select a row.
This seems to negate the following:
"If the user is performing a range selection, the cell that is defining the farthest extent of the range is the active cell. (The range is determined by the relationship of the position of the active cell to that of the "anchor" cell, or the cell that was active when the range selection was initiated.)"
This bug occurs when a row is selected and then another row is selected. It would seem the active cell is being used as an offset, yet it is null, therefore the scroll position internally is 0 instead of whatever it should be. This is a guess on my part, but it's pretty consistent that the scrolling to top=0 thing happens specifically when the selection moves rows and there was no active cell previously. When a row is selected, active cell is null, so even if you select a row far down, when you select another, you're popped to the top.
Will post more if I find a solution.

Vince - could you answer how to stop the scrolling that occurs on row select? I think the original post was complaining about the scrolling.
revbones,
I believe that this would be best handled by submitting a support request, likely including a full application that Developer Support can run and debug for testing purposes.
I don't currently have an environment in which to test this myself. I'm also not sure what scrolling behavior is being described. Because of these reasons, I can't tell whether this is expected behavior, a potential bug in our controls, or a compatibility issue with Internet Explorer 8.
Was there ever an answer as to why it scrolls to the top when a row is selected? I am having the same problem. scrollToView does not work either.
This happens with WebGrid and WebHierarchalGrid as well.
Can someone please explain how to stop it!!
I too have the same problem with 2009.2 and 2010.2, all service releases. Very annoying when there is more than 1 page of data and you click to expand a row and the page scrolls to the top.
