检查是否已选中“全选”复选框

Question

so i have a telerik client grid with a gridclientselectcolumn. Im trying to figure out when the select all checkbox is clicked.

something like:

function(sender, e){
if (e.SELECTALLCHECKBOX){
//do something
}

is there a way to simply check if the checkbox has been clicked.

Thanks

I hate to be the guy who always recommends jQuery but . . . I would recommend jQuery.

$('#selectAllCheckbox:checked').on('change', function(e) {
    if ($(this).prop('checked') {
        $('#otherCheckbox').prop('checked', true);
    }
    else {
        $('#otherCheckbox').prop('checked', false);
    }
}

Be careful about using .prop() as opposed to .val(). There are some subtle differences that can get you in trouble.
