以下是引用片段:
其主要代码实现过程如下: protected void Page_Load(object sender, EventArgs e) { // 在此处放置用户代码以初始化页面 if (!Page.IsPostBack) { //绑定配件类别列表 this.Dropdownlist1.DataTextField = "clmc"; this.Dropdownlist1.DataValueField = "clbh"; this.Dropdownlist1.DataSource = DataBase.Get_Table("select * from clxx where clzt <> '停运'"); this.Dropdownlist1.DataBind(); this.Dropdownlist1.SelectedIndex = 0;
this.Textbox4.Text = DateTime.Now.ToString("yyyy-MM-dd hh:mm"); this.Textbox5.Text = DateTime.Now.ToString("yyyy-MM-dd hh:mm"); this.Textbox4.Attributes["readonly"] = "true"; this.Textbox5.Attributes["readonly"] = "true";
if (Request.QueryString["ID"] != null) { //显示当前的车次信息 DataTable tmpda = new DataTable(); tmpda = DataBase.Get_Table("select * from ccxx where idkey = " + Request.QueryString["ID"]); if (tmpda.Rows.Count > 0) { this.Textbox1.Text = tmpda.Rows[0]["ccmc"].ToString(); this.Textbox2.Text = tmpda.Rows[0]["fcz"].ToString(); this.Textbox3.Text = tmpda.Rows[0]["dzz"].ToString(); this.Textbox4.Text = Convert.ToDateTime(tmpda.Rows[0]["fcsj"].ToString()).ToString("yyyy-MM-dd hh:mm"); this.Textbox5.Text = Convert.ToDateTime(tmpda.Rows[0]["ddsj"].ToString()).ToString("yyyy-MM-dd hh:mm"); this.Textbox6.Text = tmpda.Rows[0]["pj"].ToString(); this.Textbox7.Text = tmpda.Rows[0]["ytsjd"].ToString();
this.Dropdownlist1.SelectedValue = tmpda.Rows[0]["clbh"].ToString(); this.Dropdownlist2.SelectedValue = tmpda.Rows[0]["cczt"].ToString(); } } }
