如何使用转发器控件在下拉列表中设置默认选择？

问题描述

protected void rpt_OnItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        try
        {
            DataTable dtFarmers = new DataTable();
            dtFarmers = objdailyreportBAL.Getfarmers();

            DropDownList ddl = (DropDownList)e.Item.FindControl("ddlfarmername");
            if (ddl != null)
            {

                ddl.DataSource = dtFarmers;
                ddl.DataTextField = "farmernamevilage";
                ddl.DataValueField = "Farmername";
                ddl.DataBind();
                ddl.Items.Add(new ListItem("--Select--", "0"));
                ddl.SelectedIndex = DDLfarmername.Items.Count - 1;
            }
         }
     }

推荐答案

ddl.DataBind();
            ddl.Items.Insert(0,new ListItem("--Select--", "0"));
            ddl.SelectedIndex = DDLfarmername.SelectedIndex;

//不确定这个线路..



如果您遇到任何问题，请回来。

// not sure with this line..
