WinForm 分页控件

测试截图

控件设计

新建一个Pagination类，继承自System.Windows.Forms.UserControl。设定好用户控件的大小，托入一个TableLayoutPanel控件到UserControl上，根据实际情况布局好所需控件，如上图所示。（注：以下源码中的Button和TextBox继承自自定义的控件，非WinForm原生控件，因此部分属性原生控件可能不存在，请自行根据情况修改）

调用

新建一个WinForm程序，在Form上拖入Pagination控件、ListView控件、Label控件。添加Form的Load事件以及Pagination的PageChanged事件。（如下图所示）

 调用源码

        private void Form1_Load(object sender, System.EventArgs e)
        {
            PaginationTest.TotalCount = 945;
            ListViewTest.Columns.Add("Index");
            ListViewTest.Columns.Add("Number");
        }

        private void PaginationTest_PageChanged(int startIndex, int pageSize)
        {
            ListViewTest.Items.Clear();
            for (int i = startIndex; i < startIndex + pageSize; i++)
            {
                System.Windows.Forms.ListViewItem lvi = new System.Windows.Forms.ListViewItem((i + 1).ToString("000"));
                lvi.SubItems.Add((i + 1).ToString("000"));
                ListViewTest.Items.Add(lvi);
            }

            int page = ((startIndex + 1) / PaginationTest.PageSize) + 1;
            int totalPage = System.Convert.ToInt32(System.Math.Ceiling((double)PaginationTest.TotalCount / PaginationTest.PageSize));
            label1.Text = "总共 " + PaginationTest.TotalCount + " 条数据，每页显示 " + PaginationTest.PageSize + " 条，当前第 " + page + " 页， 共 " + totalPage + " 页";
        }
