How can disable checkbox all rows in datatable?

Hello. I have a question.
I know how to apply css to a row that meets certain conditions when I do onbeforeload of datatables.
But how do I search the input boxes inside?

In my site, code like this.

var dialogGrid = $('#LEQPEN011_3_GMASTR001_grid');
dialogGrid.attachEvent('onItemDblClick', function(rowId, e, node) {
	var data = this.getItem(rowId);
	var row = grid2.getItem($rowId);
	row = $.extend({}, row, data);
	row.id = $rowId;
	grid2.updateItem(row.id, row);
	grid2.refresh();
	rowData = {};
});

ex) Condition is A = B. all rows data is different.
if A = 1, B = 2 then false.
else A = 1, B = 1 then true.
when condition is true then checkbox is disabled.

At the grid.onBeforeRender event, I want to know how to implement the code to disable checkbox for that row when certain conditions are true.

Please answer me.

somebody help me…

Hi @Juste,
Could you please describe the issue you’ve encountered in more detail and provide an example (using our Snippet Tool)?
Do you need when double-clicking on a row in one datatable, depending on the conditions, the state of the checkbox changes in another datatable? If so, here’s a basic example:
