I have created a grid which retrieves data from a database through a store using a json reader. The grid has a few custom buttons in the toolbar with custom routines.
I have noticed if I load the page and then continually add a filter to a column using the drop down, then clear the filter (using grid.filters.clearFilters();) and repeat, after between 5 and 10 iterations, the scroll bar on the grid will stop working. You can drag it up and down but the data in the grid does not move.
What could be causing this be as it seems to be independent of any code I have written. Any help would be appreciated. Thanks
