如何通过xml如何动态绑定gridview

一效果：

二，核心代码：

1.读取xml文件，返回datatable

    /// 

        /// 获取xmltable
        /// 
        /// xml名字
        /// 
        public DataTable getDTXML(string xmlname)
        {
            DataTable result = new DataTable();
            string fileName = HttpContext.Current.Request.PhysicalApplicationPath + "\\Xml\\" + xmlname + ".xml";//xml的物理路径
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(fileName);
            XmlNodeList xWitsTablesList = xmlDoc.SelectNodes("/config");
            foreach (XmlNode xOracleNode in xWitsTablesList)
            {
                foreach (XmlNode node2 in xOracleNode.ChildNodes)
                {
                    if (node2.Name == "Header")
                    {
                        //   //绑定表头
                        foreach (XmlNode node3 in node2.Attributes)
                        {
                            result.Columns.Add(node3.Value);
                        }
                    }
                    else
                    {
                        //数据行
                        int i = 0;//列标志
                        DataRow dr = result.NewRow();
                        foreach (XmlNode node4 in node2.Attributes)
                        {
                            dr[i] = node4.Value.ToString();
                            i++;
                        }
                        result.Rows.Add(dr);
                    }

                }
            }
            return result;
        }

2.绑定gridview列

    /// 

    /// 绑定gridview列
    /// 
    /// 
    /// 
    /// 
    /// 
    public void HtmlGridView(GridView gv,DataTable dt,int width,int columnNumber)
    {
        try
        {
            int k=0;
            if (dt.Rows.Count > 0)
            {
                foreach (DataRow dr in dt.Rows)
                {
                    BoundField bf = new BoundField();
                    bf.HeaderText = dr["name"].ToString();
                    bf.DataField = dr["field_code"].ToString();
                    bf.HeaderStyle.Width = Convert.ToInt32(dr["width"].ToString());
                    bf.HeaderStyle.HorizontalAlign = HorizontalAlign.Center;
                    bf.HeaderStyle.ForeColor = System.Drawing.Color.Black;
                    bf.SortExpression = dr["name"].ToString();
                    gv.Columns.Add(bf);
                    k+= Convert.ToInt32(dr["width"].ToString());
                    if (dr["width"].ToString()=="0")
                    {
                        gv.Columns[columnNumber].Visible = false;
                    }
                    columnNumber++;
                }
                gv.Width = k + width;
            }
 
        }
        catch(Exception ex)
        {
            throw new Exception(ex.Message);
        }
    }

                  <%#Eval("NO") %>
                
              
            
        
      
     

    

    

 
     function add_clear() {

             $(this).val('');
