　　本文主要讲述如何给Dev ASPxGridView后台增加列，希望对大家有帮助。

public void BindRecordList()

{

    String sqlAll=”select ID,”;

     if (ASPxGridView1.Columns.Count == 0)

            {

                //手动绑定数据

  DevExpress.Web.ASPxGridView.GridViewDataTextColumn dl = new DevExpress.Web.ASPxGridView.GridViewDataTextColumn();

dl.Caption = "显示出来的头部";

               dl.FieldName = "AgentId";

                gvRecordList.Columns.Add(dl);

                //从数据库中取的要绑定的列名与描述

                DataTable dsWidth = gd.getGradeReg();

                String Sqlcolumn=””;

                for (int i = 0; i < dsWidth.Rows.Count; i++)

            ;&nbsp;   {

 DevExpress.Web.ASPxGridView.GridViewDataTextColumn datacolumn = new DevExpress.Web.ASPxGridView.GridViewDataTextColumn();

          &nbsp;         //绑定列的描述

                    datacolumn.Caption = dsWidth.Rows[i]["GrShow"].ToString();

  ;                  //绑定列的字段

                    datacolumn.FieldName = dsWidth.Rows[i]["GrName"].ToString().Trim();

                    datacolumn.UnboundType = DevExpress.Data.UnboundColumnType.Bound;

          &nbsp;         ASPxGridView1.Columns.Add(datacolumn);

                    //取得sql语句中的字段

            &nbsp;       Sqlcolumn+=” , “+ dsWidth.Rows[i]["GrName"].ToString().Trim()

              ;  }

  &nbsp; &nbsp;       }

      &nbsp;     DataSet dsRecord = null;

    &nbsp;  &nbsp;    try

         &nbsp;  {//取得完整的sql语句

                sqlAll += ColonmFileds + &quot; from Recording " + sqlQuery();

         &nbsp; &nbsp;    dsRecord = SQLHelper.Query(sqlAll);

  &nbsp; ;            //绑定数据源

&nbsp;               ASPxGridView1.DataSource = dsRecord.Tables[0].DefaultView;

            &nbsp;   ASPxGridView1.DataBind();

           ; }

       &nbsp;    catch

     ;       {

       &nbsp;        throw;

         &nbsp;   }

        }

GridView在后台动态绑定列或者增加列的语句为：

for (int i = 0; i < dsWidth.Rows.Count; i++)

     &nbsp;      {

                BoundField bf = new BoundField();

   ;   &nbsp;         bf.DataField = dsWidth.Rows[i]["GrName"].ToString().Trim();//字段名

                bf.HeaderText = dsWidth.Rows[i]["GrShow"].ToString();//列名

 &nbsp;              GridView1.Columns.Insert(i, bf);

      &nbsp;     }
