推荐答案

3层体系结构必须处理获取数据.您的数据绑定(无论检索到什么)仅是一个参与者-基于前端.
因此，根据您的图层逻辑，可以在前端获取XML格式的数据.拥有它后，使用它将其与网格绑定.

看这里:

3 layer architecture has to deal with getting the data. Your binding of data (whatever retrieved) is only one player - front end based.
so, based on your layer logic, get the data in XML format in your frontend. Once you have it, use it to bind it with grid.

我在举一个简单的例子

i am giving a simple example

private void ReadxmlFromXmlTextReader(string file_Path )
    {
        DS_purchase = new DataSet(); // Create the DataSet to read the schema into.    
        FileInfo FInfo = new FileInfo(file_Path);
        if (FInfo.Exists)
        {
            System.Xml.XmlTextReader xmlReader = new System.Xml.XmlTextReader(FInfo.FullName);
            xmlReader.WhitespaceHandling = WhitespaceHandling.None;
            try
            {
                DS_purchase.ReadXml(xmlReader);
               }
            catch (Exception ex)
            {
                    
            }
            finally
            {
                xmlReader.Close();
            }

        }
        
    }
