Grid filter

how to set the id for the filters and get the id of the filter

If you meant the id of filter html element, you can get this element by DOM:

- for select filter:
var el = grid.hdr.rows[2].cells[COLUMN_INDEX].getElementsByTagName(“SELECT”)[0];
- for text:
var el = grid.hdr.rows[2].cells[COLUMN_INDEX].getElementsByTagName(“INPUT”)[0];

Then you can set id for this element: = “some id”;
