选中checkbox改变它所在的gridview单元格的背景颜色
请问怎样实现这个功能？
注意是gridview单元格的背景色

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox cb = e.Row.FindControl("CheckBox1") as CheckBox;
string id = GridView1.DataKeys[e.Row.RowIndex].Value.ToString();
if (cb != null)
{
cb.Attributes.Add("onclick", "changeColor('" + cb.ClientID + "'," + id + ");");
}
}
}
function changeColor(cb, id) {
var tr = document.getElementById(cb).parentElement.parentElement;
tr.style.backgroundColor = "red";
}
