本文主要講述如何給Dev ASPxGridView后臺增加列，希望對大家有幫助。

public void BindRecordList()

{

    String sqlAll=”select ID,”;

     if (ASPxGridView1.Columns.Count == 0)

      ;      {

                //手動綁定數(shù)據(jù)

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

dl.Caption = "顯示出來的頭部";

               dl.FieldName = "AgentId";

                gvRecordList.Columns.Add(dl);

                //從數(shù)據(jù)庫中取的要綁定的列名與描述

                DataTable dsWidth = gd.getGradeReg();

          ;      String Sqlcolumn=””;

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

                {

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

                    //綁定列的描述

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

                    //綁定列的字段

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

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

   ;                 ASPxGridView1.Columns.Add(datacolumn);

   &nbsp;                //取得sql語句中的字段

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

   &nbsp;            }

  &nbsp;  &nbsp;      }

     &nbsp;      DataSet dsRecord = null;

         &nbsp;  try

            {//取得完整的sql語句

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

 ;               dsRecord = SQLHelper.Query(sqlAll);

&nbsp;         &nbsp;     //綁定數(shù)據(jù)源

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

    &nbsp;           ASPxGridView1.DataBind();

       &nbsp;    }

        &nbsp;   catch

   &nbsp; &nbsp;      {

                throw;

    &nbsp;     ;  }

        }

GridView在后臺動態(tài)綁定列或者增加列的語句為：

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

    &nbsp;       {

        &nbsp;       BoundField bf = new BoundField();

     ;           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);

        ; ;   }
