Hi. In application I maintain jqgrid used to get data.

So, there is a filter and a grid (jqgrid) filtered data load in. Searching appropriate data for filter is rather long operation.

Now when page is load and jqgrid allocated it queries server with default filter.

And after that users can fill filter click search button and get results.

So, when they first time come on page they see set of data filtered by default filter – and they didn't want it.
