I have another example of this same behavior where the active cell gets "stuck" when i edit the last cell in a column in a virtual grid. I can''t hit the left arrow key (to move to the cell to the left) for about 4 seconds.
If i type in data and hit enter to committ, i can''t move the active cell back to the the left for a few seconds. I hit the left arrow key but it takes 4 seconds for it to actually move.
NOTE:
On the QueryNextCurrentCellPosition event, i call
grid.CurrentCell.EndEdit(); to make sure it commits because by default it stays in editing mode.
i have added this code to the example project and upload the solution again . I named it VirtualGridwithlastColissueadded.zip
VirtualGridwithlastColissueadded0.zip
