Without using the jQuery library, you could do something like this:

JavaScript

//when calling check and uncheck send in the element grid id

function check(GridID) {
    docheck(GridID, true);
}

function uncheck(GridID) {
    docheck(GridID, false);
}

function docheck(GridID, CheckOrNotToCheck) {
//note: to get a list of all input elements - document.getElementsByTagName('INPUT')
    var InputList = document.getElementById(GridID).getElementsByTagName('INPUT');
    for (var i = 0; InputList[i]; i++) {
        if (InputList[i].type === 'checkbox') {
            InputList[i].checked = CheckOrNotToCheck;
        }
    }
}

Use Jquery to check all checkboxes

JavaScript

 $("#btnSelectAll").live("click", function () {                          
                            $('#gridID').find("input:checkbox").each(function () {
                                this.checked = true;
                            });
                        });

$("#btnDeselectAll").live("click", function () {                          
                            $('#gridID').find("input:checkbox").each(function () {
                                this.checked = false;
                            });
                        });
