以上为前台代码👆
后台代码：
/// <summary> /// 保存临时表datatable /// </summary> protected DataTable dt0 { get { return (DataTable)ViewState["dt0"]; } set { ViewState["dt0"] = value; } } protected void btnDel_Click(object sender, ImageClickEventArgs e) { int cfs = Convert.ToInt32(cftsTB.Text); if (cfs > 1) { dt0.Rows.RemoveAt(Convert.ToInt32(hdGuid.Value)); PageDataList.BindGridView(GridViewData, dt0); cftsTB.Text = string.Format("{0}", cfs - 1); } else { PageHelper.MessageBox(this, "拆分数目需要大于1！"); } }
问题在于，①创建一个全局的临时表变量 dt0 ，用于调用和修改；②使用datatable的属性方法来进行操作、如
PageDataList.BindGridView(GridViewData, dt0);
dt0.Rows.RemoveAt(Convert.ToInt32(hdGuid.Value));
删除是根据 页面序号(hdGuid.Value)来进行操作的
附上通常创建临时表的代码：
public void creatCfdt(decimal cfNum) { string result = null; ZcKcbEntity kcb = new ZcKcbAction().GetInfo(guid); DataTable data = new DataTable(); data.Columns.Add(new DataColumn("guid", System.Type.GetType("System.String"))); data.Columns.Add(new DataColumn("zcmc", System.Type.GetType("System.String"))); data.Columns.Add(new DataColumn("czcode", System.Type.GetType("System.String"))); data.Columns.Add(new DataColumn("dj", System.Type.GetType("System.Decimal"))); data.Columns.Add(new DataColumn("je", System.Type.GetType("System.Decimal"))); data.Columns.Add(new DataColumn("syr", Type.GetType("System.String"))); data.Columns.Add(new DataColumn("sybm", System.Type.GetType("System.String"))); data.Columns.Add(new DataColumn("syfx", System.Type.GetType("System.String"))); data.Columns.Add(new DataColumn("cfdd", System.Type.GetType("System.String"))); data.Columns.Add(new DataColumn("djsj", System.Type.GetType("System.DateTime"))); data.Columns.Add(new DataColumn("sl", Type.GetType("System.Decimal"))); DataRow row2 = data.NewRow(); row2["guid"] = kcb.guid; row2["zcmc"] = kcb.zcmc; row2["czcode"] = kcb.czcode; row2["dj"] = kcb.dj; row2["je"] = kcb.je; row2["syr"] = kcb.syr; row2["sybm"] = kcb.sybm; row2["syfx"] = kcb.syfx; row2["cfdd"] = kcb.cfdd; row2["djsj"] = kcb.djsj; row2["sl"] = kcb.sl - cfNum + 1; data.Rows.Add(row2); dt0 = data; if (data != null) { //绑定数据 if (!PageDataList.BindGridView(GridViewData, data)) { result = "绑定列表失败!"; } } else { result = "获取数据失败!"; } //返回结果 PageHelper.MessageBox2(this, result); }
