onBeforeFilter

called before data are filtered

void onBeforeFilter(string id,string value,object config);

id	string	the column ID
value	string	the value to be filtered by
config	object	the filter configuration

Example

dtable.attachEvent("onBeforeFilter", function(id, value, config){
    //ignores short filter-strings during filtering
    if (value.length < 3) return false;
})

Details

The event fires only for built-in Datatable, Treetable, and Excelviewer filters. To catch the moment when view data are filtered by the API, handle the onBeforeFilter event of its Datastore.

Returning false within an event handler will prevent data filtering.

If you have several filters, the event will fire for every one of them.
