C# DataGridView合計行

在網上搜了很多關於DataGridView合計行的設計及源碼，都不是很合我心意。於是自己寫了一個關於合計行的DLL。以后每次要用到合計行的時候只要引用這個DLL就可以了。

 

效果圖如下：

 

 

 

 

引用Dll：

 

附上例子源碼：

 

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        TSumRow.TSumCols tsc = new TSumRow.TSumCols();
        List<Jyinfo> ListJy = new List<Jyinfo>();

        private void Form1_Load(object sender, EventArgs e)
        {
            DGV.AutoGenerateColumns = false; //禁止自動創建列
            DGV.AllowUserToResizeColumns = false; //禁止自動調整列寬
        }

        private void button1_Click(object sender, EventArgs e)
        {
            GetData();
        }

        /// <summary>
        /// 獲取數據
        /// </summary>
        private void GetData()
        {
            Jyinfo j = null;
            List<Jyinfo> listjy = new List<Jyinfo>();
            using (SqlConnection conn = new SqlConnection("Data Source=.;Initial Catalog=Test;User ID=sa;Password=123456"))
            {
                conn.Open();
                SqlCommand cmd = conn.CreateCommand();
                cmd.CommandText = @"SELECT [Id],[Name],[Age],[Sl],[Zl],[Dj],[Je] FROM [dbo].[JyInfo]";
                SqlDataReader reader = cmd.ExecuteReader();
                while (reader.Read())
                {
                    j = new Jyinfo();

                    j.Id = Convert.ToInt32(reader["Id"]);
                    j.Name = reader["Name"].ToString();
                    j.Age = Convert.ToInt32(reader["Age"]);
                    j.Sl = Convert.ToInt32(reader["Sl"]);
                    j.Zl = Convert.ToInt32(reader["Zl"]);
                    j.Dj = Convert.ToInt32(reader["Dj"]);
                    j.Je = Convert.ToInt32(reader["Je"]);

                    listjy.Add(j);
                }
                reader.Close();
            }
            ListJy = listjy;
            DGV.DataSource = ListJy;


            #region 匯總行  《以下就是顯示DataGridView合計行的代碼》
            List<TSumRow.TColumns> listTc = new List<TSumRow.TColumns>();
            TSumRow.TColumns Tc = new TSumRow.TColumns();
            Tc.Col_Name = "Col_Id";    //DataGridView列的序號列列名
            Tc.Col_Value = "合計：";   //要顯示在合計行的值
            listTc.Add(Tc);

            Tc = new TSumRow.TColumns();
            Tc.Col_Name = "Col_Name";    //DataGridView列的姓名列列名
            var q = from b in ListJy
                    group b by b.Name;
            Tc.Col_Value = q.Count().ToString();//匯總多少個客戶
            listTc.Add(Tc);

            Tc = new TSumRow.TColumns();
            Tc.Col_Name = "Col_dj";     //DataGridView列的單價列列名
            Tc.Col_Value = string.Format("{0:F2}", ListJy.Average(a => a.Dj));//平均單價
            listTc.Add(Tc);

            Tc = new TSumRow.TColumns();
            Tc.Col_Name = "Col_je";    //DataGridView列的金額列列名
            Tc.Col_Value = string.Format("{0:F2}", ListJy.Sum(a => a.Je)); ;//總的銷售額
            listTc.Add(Tc);

            tsc.AddHz(listTc, DGV, pan);
            #endregion
        }
    }

    /// <summary>
    /// 交易信息實體類
    /// </summary>
    [Serializable]
    public class Jyinfo
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public int Age { get; set; }
        public int Sl { get; set; }
        public int Zl { get; set; }
        public int Dj { get; set; }
        public int Je { get; set; }
    }
}

合計我使用的是Panel對象。

定義對象：Panel對象名為pan,DataGridView對象名為DGV
