Event Handling

## onDynXLS Event

Occurs before requesting additional data from the server in case of dynamic smart rendering or dynamic paging. Blockable.

              grid.attachEvent("onDynXLS", function(start,count){
                        //any custom logic here
              });

Parameters:

- start - {int} position from which data requested;
- count - {int} count of rows requested.

This event can be used to implement custom URI building in dynamic loading.

              grid.attachEvent("onDynXLS", function(start,count){
                       grid.load("some.com/load/"+start+"?size="+count);
                       return false;
              });
