c#中如何不通过后台直接用js筛选gridview中的数据条件筛选查询？

js：

//条件筛选

var showstate = true;
function imagechange() {
if (showstate) {

$('#_toggle').hide(500, function () {
showstate = false;
image_logo.SetImageUrl("/Content/Images/01.png");
});
}
else {
$('#_toggle').show(500, function () {
showstate = true;
image_logo.SetImageUrl("/Content/Images/02.png");
});
}

}
function bt_select() {
//alert(cb_goodstype.GetValue());
updateGrid();
};

function updateGrid() {
var filterCondition = " 1=1 ";

var myDate = new Date();
//开始日期
// var end_s = ASPxDateEdit2.GetValue(); //获取今天的日期
// theDate = myDate.toLocaleDateString();
//获取控件选择的日期并进行转换
var star_s = cb_credate.GetValue(); //获取填写的日期
var star_y = new Date(star_s).getFullYear();
var star_m = new Date(star_s).getMonth() + 1;
