winform 调用存储过程显示分页列表

直接贴代码吧

SqlHelper

上图是分页列表显示页面，其对应的.cs 代码如下：

Title

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;

    {
        SqlHelper db = new SqlHelper();

        public int NowPage = 1, PageCount = 1, PageSize = 20;
        public Form1()
        {
            InitializeComponent();
        }
        public void BindData()
        {
            setBtnStatus();

         //这里是调用存储过程并传入页码和当前页面
            this.dataGridView1.DataSource = db.ExecuteDataSetProc("Pagination", PageSize, NowPage).Tables["TGongWen"];        
        }  
        private void Form1_Load(object sender, EventArgs e)
        {
            BindData();
        }
        //计算余页
        public int OverPage()
        {
            int pages = 0;
            if (rowcount % PageSize != 0)
                pages = 1;
            else
                pages = 0;
            return pages;
        }
        public void setBtnStatus()
        {
           rowcount= db.ReturnRowCount("select count(1) from TGongwen ");
           PageCount = rowcount / PageSize + OverPage();
            this.label2.Text="共"+PageCount+"页 共"+rowcount+"条记录";
            this.label1.Text = "当前是第" + NowPage + "页";
            if (NowPage > 1)
            {
                this.button5.Enabled = true;
                this.button6.Enabled = true;
            }
            else
            {
                this.button5.Enabled = false;
                this.button6.Enabled = false;
            }
            if (NowPage == PageCount)
            {
                this.button7.Enabled = false;
                this.button8.Enabled = false;
            }
            else
            {
                this.button7.Enabled = true;
                this.button8.Enabled = true;
            }       
        }
        private void button5_Click(object sender, EventArgs e)
        {
            NowPage = 1;
            Form1_Load(sender,e);
        }
        private void button6_Click(object sender, EventArgs e)
        {
            NowPage -= 1;
            Form1_Load(sender,e);
        }
        private void button7_Click(object sender, EventArgs e)
        {
            NowPage += 1;
            Form1_Load(sender,e);
        }
        private void button8_Click(object sender, EventArgs e)
        {
            NowPage = PageCount;
            Form1_Load(sender,e);
        }
        private void button2_Click(object sender, EventArgs e)
        {
            string id = this.dataGridView1.SelectedRows[0].Cells[0].Value.ToString();
            if (db.ExecuteNonQuery("delete from TGongwen where gid=" + id)>0)
            {
                MessageBox.Show("删除成功");
            }
            Form1_Load(sender, e);
        }
        private void button3_Click(object sender, EventArgs e)
        {
            Manager m = new Manager();
            m.CmdType = "edit";
            m.Id = Convert.ToInt32(this.dataGridView1.SelectedRows[0].Cells[0].Value.ToString());
            m.Show();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            Manager m = new Manager();
            m.CmdType = "add";
            m.Show();
        }    
    }
}

新增数据和修改数据页面以及所对应的.cs 文件

Manager

    {
        SqlHelper db = new SqlHelper();

        }
        private string cmdType;

        public string CmdType
        {
            get { return cmdType; }
            set { cmdType = value; }
        }
        private int id;

        public int Id
        {
            get { return id; }
            set { id = value; }
        }
        public void GetModelData()
        {
            DataSet ds = db.ReturnDataSet("select * from tgongwen where gid=" + Id);
            if (ds.Tables[0].Rows.Count > 0)
            {
                this.textBox1.Text = ds.Tables[0].Rows[0]["title"].ToString();
                this.textBox2.Text = ds.Tables[0].Rows[0]["neibuyonghu"].ToString();
                this.textBox3.Text = ds.Tables[0].Rows[0]["reader"].ToString();
            }
        }
        private void button1_Click(object sender, EventArgs e)
        {     
            if (CmdType == "add")
            {
                if (add() > 0)
                {
                    MessageBox.Show("添加成功！");
                    button2_Click(sender, e);
                }
            }
            else
            {
                if (update() > 0)
                {
                    MessageBox.Show("修改成功！");
                    button2_Click(sender,e);
                }
            }

        }
        public int add()
        {
           return db.ExecuteNonQuery("insert into tgongwen (title,fariqi,neibuyonghu,reader)values('"+this.textBox1.Text+"','"+System.DateTime.Now.ToString()+"','"+this.textBox2.Text+"','"+this.textBox3.Text+"')");
        }
        public int update()
        {
            return db.ExecuteNonQuery("update tgongwen set title='"+this.textBox1.Text+"',neibuyonghu='"+this.textBox2.Text+"',reader='"+this.textBox3.Text+"' where gid="+Id );
        }
        private void button2_Click(object sender, EventArgs e)
        {
            Form1 f = new Form1();
            f.Show();
            this.Close();
        }
        private void Manager_Load(object sender, EventArgs e)
        {
            GetModelData();
        }
    }
}

对了，还有存储过程忘记贴了就在下面

到此结束。
