winform 调用存储过程显示分页列表

直接贴代码吧

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;
using System.Windows.Forms;

namespace ADMEWinForm
{
public partial class Form1 : Form
{
SqlHelper db = new SqlHelper();
public int rowcount;
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

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

namespace ADMEWinForm
{
public partial class Manager : Form
{
SqlHelper db = new SqlHelper();
public Manager()
{
InitializeComponent();
}
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。
