动态添加标签 [英] add tags dynamically

问题描述

嗨！
我在数据库中有一个表，该表由7个colms名称，open，close，low，high，target，currency组成.我有一个asp.net网页，它包含一个图像，在该图像上有3个文本框和4个标签.


我想要一种机械方法，也可以动态添加给定图像以及标签和文本框，从表中获取值并将其分配给这些标签和texbox.假设表中有20个输入项，则应在20个以上类型的图像上添加标签和文本框.

推荐答案

这是一个动态创建HTML控件的示例.
希望对您有帮助.
您可以在sb.AppendLine
中使用标签

This is an example to create HTML controls dynamically.
hope it helps you.
you can use tags in sb.AppendLine

public static System.Web.UI.HtmlControls.HtmlGenericControl select_Emp(Page p, string userid)
    {
        String[] ss=new String[6];
        SqlCommand cmd7 = new SqlCommand();
        cmd7.CommandText = "select_Emp";
        cmd7.CommandType = CommandType.StoredProcedure;
        cmd7.Connection = Db.GetConnection();
        cmd7.Parameters.AddWithValue("@userid", userid);
        SqlDataReader dr7 = cmd7.ExecuteReader();
        

        System.Web.UI.HtmlControls.HtmlGenericControl dynDiv =
        new System.Web.UI.HtmlControls.HtmlGenericControl("DIV cssClass='roundedPanel'");
        dynDiv.ID = "dynDivCode";
        dynDiv.Style.Add(HtmlTextWriterStyle.BackgroundColor, "Gray");
        dynDiv.Style.Add(HtmlTextWriterStyle.Height, "20px");
        dynDiv.Style.Add(HtmlTextWriterStyle.Width, "300px");
        //dynDiv.Controls.Add("Panel");
       // dynDiv.InnerHtml = "I was created using Code Behind";


        if (dr7.Read())
        {
            StringBuilder sb = new StringBuilder();
            sb.AppendLine("Employee Name : " + dr7[0].ToString() + "");
            sb.AppendLine("Designation : " + dr7[1].ToString() + "<br />");
            sb.AppendLine("Department : " + dr7[2].ToString() + "");
            sb.AppendLine("Location : " + dr7[3].ToString() + "<br />");
            sb.AppendLine("Email ID : " + dr7[4].ToString() + "");
            sb.AppendLine("Office No. : " + dr7[5].ToString() + "");
            sb.AppendLine("Personal Contact No : " + dr7[6].ToString() + "");
            sb.AppendLine("Address : " + dr7[7].ToString() + "<br />");
            dynDiv.InnerHtml = sb.ToString();//Finally assign the dynamic value to the dynamic DIV
            p.Controls.Add(dynDiv);

        }

        return dynDiv;
    }

您可以为此使用DataRepeater控件.

you may use DataRepeater control for that.
