这篇文章主要介绍了ASP.NET中repeater控件用法,实例分析了repeater控件数据绑定、删除等相关技巧,具有一定实用价值,需要的朋友可以参考下

本文实例讲述了ASP.NET中repeater控件用法。分享给大家供大家参考。具体实现方法如下

repeater绑定数据

代码如下:
protected void Page_Load(object sender, EventArgs e)
{
        if(!IsPostBack)
            BindStudent();
}

private void BindStudent()
{
        string str = ConfigurationManager.ConnectionStrings["stun"].ConnectionString;
        using (SqlConnection sqlCnn = new SqlConnection(str))
        {
            using (SqlDataAdapter da = new SqlDataAdapter("select from student", sqlCnn))
            {
                DataSet ds = new DataSet();
                da.Fill(ds);
                this.Repeater1.DataSource = ds;
                this.Repeater1.DataBind();
            }
        }
}

删除数据

代码如下:
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
        if (e.CommandName == "Delete")
        {
            string str = ConfigurationManager.ConnectionStrings["stun"].ConnectionString;
            using (SqlConnection sqlCnn = new SqlConnection(str))
            {
                using (SqlCommand sqlCmm = sqlCnn.CreateCommand())
                {
                    sqlCnn.Open();
                    sqlCmm.CommandText = "delete from student where sid="
                        + e.CommandArgument.ToString();
                    sqlCmm.ExecuteNonQuery();
                }
            }
            this.BindStudent();
        }
        else if (e.CommandName == "Edit")
        {
            Server.Transfer("Edit.aspx?sid=" + e.CommandArgument.ToString());
        }
}

前台

代码如下:

启用，禁用

代码如下:
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
        //string status = e.CommandName;
        if ((e.CommandName == "true")||(e.CommandName == "false"))
        {
            string str = ConfigurationManager.ConnectionStrings["stun"].ConnectionString;
            using (SqlConnection sqlCnn = new SqlConnection(str))
            {
                using (SqlCommand sqlCmm = sqlCnn.CreateCommand())
                {
                    sqlCnn.Open();
                    sqlCmm.CommandText = "update student set status=@status where sid="
                        + e.CommandArgument.ToString();
                    sqlCmm.Parameters.AddWithValue("@status",e.CommandName);
                    sqlCmm.ExecuteNonQuery();
                }
            }
            this.BindStudent();
        }
}
