关于AspxGridView中找控件的问题，各位大虾帮忙看看

Question

点击一个按钮时，再在AspxGridView里找checkbox，怎么找呢？这样就会报未将对象引用到对象的实例protected void btnSave_Click(object sender, EventArgs e)
        {
            for (int i = 0; i < G1.VisibleRowCount; i++)
            {
                CheckBox chkselect = G1.FindRowCellTemplateControl(i, (GridViewDataColumn)G1.Columns[2], "chkSelect") as CheckBox;
                CheckBox chkupdate = G1.FindRowCellTemplateControl(i, (GridViewDataColumn)G1.Columns[3], "chkUpdate") as CheckBox;
                CheckBox chkDelete = G1.FindRowCellTemplateControl(i, (GridViewDataColumn)G1.Columns[4], "chkDelete") as CheckBox;
                int moduleID = int.Parse(G1.GetRowValues(i, "pub_dict_value_id").ToString());
                ListBase<PubRoleAuth> lst= PubRoleAuthProvider.FindBySqlWhere(" role_id=12 and module_id=" + moduleID + "");
                if (lst.Count > 0)
                {
                    PubRoleAuth roleauth = new PubRoleAuth();
                    roleauth.Role_id = 12;
                    roleauth.Module_id = moduleID;
                    roleauth.Is_view = chkselect.Checked;
                    roleauth.Is_edit = chkupdate.Checked;
                    roleauth.Is_delete = chkDelete.Checked;
                    if (PubRoleAuthProvider.Update(roleauth))
                    {
                        ShowMessage("dasfad", false);
                        this.ShowMessage("修改权限成功！",false);
                    }
                }
                else 
                {                }
            }
        }

你应该在客户端写js，遍历整个页面来寻找input标签，然后判断该标签是否是checkbox。
