遍历Label 和遍历 DropDownList

动态增加表字段对数据库稳定性有很大影响，那只好来死的了，嘿嘿。

说明：pnlMaterial是容器名，页面中有Label1-Label40, Dropdownlist1-Dropdownlist40，如此之多控件....


  ///

    /// 遍历页面的label并赋值,    ///

    protected void RenameLabel()
    {
        foreach (Control ctr in this.pnlMaterial.Controls)
        {

            if (ctr.GetType().ToString() == "System.Web.UI.WebControls.Label")
            {
                //Response.Write("id:" + ctr.ID+ "   text:" + ((Label)ctr).Text + "
");

                if (ctr.ID.ToString().Length == 6)
                {
                   int LabelId1 = Convert.ToInt32(ctr.ID.Substring(5, 1).ToString().Trim());

                    ((Label)ctr).Text = BLL.EDI.EDIType.GetTypeName(LabelId1);
                }
              
                if (ctr.ID.ToString().Length == 7)
                {
                   int LabelId2 = Convert.ToInt32(ctr.ID.Substring(5, 2).ToString().Trim());

                    ((Label)ctr).Text = BLL.EDI.EDIType.GetTypeName(LabelId2);

                }
                
            }

        }

    }


   ///

    /// 遍历dropdownlist赋值
    ///

    protected void SetDropDownListValue()
    {
        foreach (Control ctr in this.pnlMaterial.Controls)
        {

            if (ctr.GetType().ToString() == "System.Web.UI.WebControls.DropDownList")
            {
                //Response.Write("id:" + ctr.ID + "   text:" + ((DropDownList)ctr).DataTextField.ToString() + "
");

                if (ctr.ID.ToString().Length == 13)
                {
                    int LabelId1 = Convert.ToInt32(ctr.ID.Substring(12, 1).ToString().Trim());

                    ((DropDownList)ctr).DataSource = BLL.EDI.EDIMaterial.List(LabelId1);

                    ((DropDownList)ctr).DataValueField = "mName";

                    ((DropDownList)ctr).DataTextField = "mCode";

                    ((DropDownList)ctr).DataBind();
                }

                if (ctr.ID.ToString().Length == 14)
                {
                    int LabelId2 = Convert.ToInt32(ctr.ID.Substring(12, 2).ToString().Trim());

                    ((DropDownList)ctr).DataSource = BLL.EDI.EDIMaterial.List(LabelId2);

                    ((DropDownList)ctr).DataValueField = "mName";

                    ((DropDownList)ctr).DataTextField = "mCode";

                    ((DropDownList)ctr).DataBind();
                }

            }

        }

    }
