GridView中采用来LinkButton修改表格中的数据（绑定数据在TextBox中）

本文主要是介绍GridView中采用来LinkButton修改表格中的数据（绑定数据在TextBox中），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

    【实例1】直接在数据库中读取

  protected void alter_Click(object sender, EventArgs e)//修改
        {
            Panel1.Visible = true;
            LinkButton lbt = (LinkButton)sender;
            DataControlFieldCell dcf = (DataControlFieldCell)lbt.Parent;
            GridViewRow gvr = (GridViewRow)dcf.Parent;

            //选中行标注颜色
            foreach (GridViewRow gvr1 in GV_PF.Rows)
            {
                gvr1.BackColor = System.Drawing.Color.Empty;//没有颜色，透明
            }
            gvr.BackColor = (System.Drawing.Color)(new System.Drawing.ColorConverter()).ConvertFromString("#669999");

            decimal id = Convert.ToDecimal(gvr.Cells[10].Text.Trim());
            id_main = id;

             private BLL.OriginalCertificate.AlterOriginalCertificate B_AlterOriginalCertificate = new BLL.OriginalCertificate.AlterOriginalCertificate();
            Entity.TB_OriginalCertificate E_TB_OriginalCertificate = B_AlterOriginalCertificate.getEntity(id_main);// 得到一个对象实体（model层）
            txt_Explain.Text = E_TB_OriginalCertificate.Explain;
            txt_Bills.Text = E_TB_OriginalCertificate.Bills.ToString();
            txt_TotalMoney.Text = E_TB_OriginalCertificate.TotalMoney.ToString();
            txt_Idea.Text = " 验收人：" + E_TB_OriginalCertificate.Idea_Test
                + "\n\r 主席：" + E_TB_OriginalCertificate.Idea_Chairman;

 

*****************************************************************************************

【实例2】直接在GridView中读取

 protected void lbnAlertClick(object sender, EventArgs e)  //修改记录
        {
            GridViewRow gvr = (GridViewRow)((DataControlFieldCell)(((LinkButton)(sender)).Parent)).Parent;

            //选中行标注颜色
            foreach (GridViewRow gvr1 in gvList.Rows)
            {
                gvr1.BackColor = System.Drawing.Color.Empty;//没有颜色，透明
            }
            gvr.BackColor = (System.Drawing.Color)(new System.Drawing.ColorConverter()).ConvertFromString("#9900FF");

           绑定数据在TextBox中

           txtName_File.Text = gvr.Cells[2].Text;
            txtSummary.Text = gvr.Cells[3].Text;  
            txtRemark.Text = gvr.Cells[4].Text; 

            ViewState["index"] = gvr.Cells[0].Text;

            ViewState["Id"] = gvr.Cells[1].Text;  //ID

            trAlert.Style.Value = "";
        }

 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

添加【修改】按钮

 protected void btnAlert _Click(object sender, EventArgs e)      //修改按钮操作
        {
            if (txtName_File.Text.Trim() != "" &&txtSummary.Text.Trim() != "")
            {      

               Entity.TB_ProductionPlan E_ProductionPlan = new Entity.TB_ProductionPlan();

                E_ProductionPlan.Id = Convert.ToDecimal(ViewState["Id"].ToString());

                E_ProductionPlan.Name_File = txtName_File.Text.Trim();
                E_ProductionPlan.Summary = txtSummary.Text.Trim();
                E_ProductionPlan.Id_ReportPerson = Convert.ToDecimal(Session["USER_ID"]);
                E_ProductionPlan.Date_Report = DateTime.Now;

           if (B_ProductionPlanAlert.update(E_ProductionPlan))      //更新一条记录
                {
                         msgBox.Show(this, "修改成功！");

                }

            }

}
