一个简单的分页代码

    今天看了一下同事写的分页代码 虽然效率不高 但是比我的简单多了
数据量小的首选（别忘了定义gridview的pagesize）
protected void LinkButton1_Click(object sender, EventArgs e)
    {
        GridView1.PageIndex = 0;
        BusinessWork BusinessWork = new BusinessWork();
        DataTable dt = new DataTable();
        dt = BusinessWork.BusinessWorkDataTable("Archives_DakfGetAll");
        if (dt.Rows.Count > 0)
        {
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }
    }
    protected void LinkButton2_Click(object sender, EventArgs e)
    {
        if (GridView1.PageIndex - 1 >= 0)
        {
            GridView1.PageIndex = GridView1.PageIndex - 1;
            BusinessWork BusinessWork = new BusinessWork();
            DataTable dt = new DataTable();
            dt = BusinessWork.BusinessWorkDataTable("Archives_DakfGetAll");
            if (dt.Rows.Count > 0)
            {
                GridView1.DataSource = dt;
                GridView1.DataBind();
            }
        }
    }
    protected void LinkButton3_Click(object sender, EventArgs e)
    {
        if (GridView1.PageIndex + 1 <= GridView1.PageCount)
        {
            GridView1.PageIndex = GridView1.PageIndex + 1;
            BusinessWork BusinessWork = new BusinessWork();
            DataTable dt = new DataTable();
            dt = BusinessWork.BusinessWorkDataTable("Archives_DakfGetAll");
            if (dt.Rows.Count > 0)
            {
                GridView1.DataSource = dt;
                GridView1.DataBind();
            }
        }
    }
    protected void LinkButton4_Click(object sender, EventArgs e)
    {
        GridView1.PageIndex = GridView1.PageCount;
        BusinessWork BusinessWork = new BusinessWork();
        DataTable dt = new DataTable();
        dt = BusinessWork.BusinessWorkDataTable("Archives_DakfGetAll");
        if (dt.Rows.Count > 0)
        {
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }
    }
