onBeforeFilter

called before data are filtered

function onBeforeFilter(
    // the column ID
    id: string,
    // the value to be filtered by
    value: string,
    // the filter configuration
    config: object
): void

Example

dgrid.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 DataGrid 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.
