CheckBoxList控件绑定数据和设置选定项

//获取属性
ProductPropertyDataSet propertyList = ProductProperty.SelectProductPropertyData();

foreach (var item in propertyList.DataList)
{
cblProperty.Items.Add(new ListItem(item.PropertyName, item.PropertyId.ToString()));
}

int id = int.Parse(Request.QueryString["id"].ToString());
DataTable dt = ProductCategory.SelectCategoryRelationPropertyDataByCategoryId(id);
for (int i=0;i<cblProperty.Items.Count;i++)
{
for (int j = 0; j < dt.Rows.Count; j++)
{
if (cblProperty.Items[i].Value == dt.Rows[j]["propertyId"].ToString())
{
cblProperty.Items[i].Selected = true;
}
}
}
