Custom Filter for Datagrid

[doev]

I need to filter a datagrid (fetches data from a remote server) in a complex way, wich means that the filter depends on some other elements from outside the datagrid. For example, on the selected rows of a second datagrid. What I need is a function, that is called when the datagrids reload is triggert, where I can pass the needed data to the request.

How can I start with this. Thx.

Solution:

$('#dg').datagrid('load', {
        data1: data1,
        data2: data2,
        data3: data3,
    });


How can I trigger it, always when a second datagrids selection changes?
