如何使用asp+ 动态创建页面元素给上次的DataGrid分页增加些功能!

<%@ Import Namespace="System.Data" %>

ICollection CreateDataSource() {
DataTable dt = new DataTable();
DataRow dr;

dt.Columns.Add(new DataColumn("IntegerValue", typeof(Int32)));
dt.Columns.Add(new DataColumn("StringValue", typeof(string)));
dt.Columns.Add(new DataColumn("DateTimeValue", typeof(string)));
dt.Columns.Add(new DataColumn("BoolValue", typeof(bool)));

for (int i = 0; i < 200; i++) {
dr = dt.NewRow();

dr[0] = i;
dr = "Item " + Int32.ToString(i);
dr = DateTime.Now.ToShortDateString();
dr = (i % 2 != 0) ? true : false;

dt.Rows.Add(dr);
}

DataView dv = new DataView(dt);
return dv;
}

void Page_Load(Object sender, EventArgs e) {
if (chk1.Checked) {
MyDataGrid.PagerStyle.Mode=PagerMode.NumericPages;
}
else {
MyDataGrid.PagerStyle.Mode=PagerMode.NextPrev;
}

BindGrid();
}

void MyDataGrid_Page(Object sender, DataGridPageChangedEventArgs e) {
BindGrid();
}

void BindGrid() {
MyDataGrid.DataSource = CreateDataSource();
MyDataGrid.DataBind();
ShowStats();
}

void ShowStats() {
lblCurrentIndex.Text = "CurrentPageIndex is " + MyDataGrid.CurrentPageIndex;
lblPageCount.Text = "PageCount is " + MyDataGrid.PageCount;
}

</script>
