aspx.cs

私有 无效 BindList() { 数据集ds = ProductController1.GetAllProducts(); lblMsg.Text = " " ; 如果(ds.Tables [ 0 ].Rows.Count > 0 ) { dlProduct.DataSource = ds; dlProduct.DataBind(); } 其他 { lblMsg.Text = " 没有这样的项目!!!请添加一个" ; } }

存储过程

ALTER 过程 [dbo].[spGetAllBrand] AS 选择品牌名称，说明来自 tblBrands 其中有效= 1

解决方案

在您的数据集中，没有可用于BrandName name的列.检查GetAllProducts中的拼写错误.尽管您尚未发布GetAllProducts的代码，但错误提示您需要验证列名.如果您没有用于存储产品的任何产品类别，则此方法应该可以正常工作.尝试添加一列描述并检查它是否对您有用? 谢谢

aspx.cs

private void BindList() { DataSet ds = ProductController1.GetAllProducts(); lblMsg.Text = ""; if (ds.Tables[0].Rows.Count > 0) { dlProduct.DataSource = ds; dlProduct.DataBind(); } else { lblMsg.Text = "No such Item !!! Please add one"; } }

stored procedure

ALTER procedure [dbo].[spGetAllBrand] AS select BrandName,Description from tblBrands where Active=1

解决方案

Hi, In your DataSet there is no column available with BrandName name. Check typo mistake in GetAllProducts. Although you have not posted code of GetAllProducts but error says that you need to verify the column name. If you do not have any class of product to store products then this should work fine. try to add one column description and check if it works for you ? Thanks
