{

this.contrlRepeater();

}
//获取指字符个数的字符
public string cuts(string aa, int bb)

PagedDataSource pds = new PagedDataSource();
pds.DataSource = kh;
pds.AllowPaging = true;

添加一个DropDownList1，用FOR循环添加LISTITEM,再为DropDownList1添加事件DropDownList1_SelectedIndexChanged（），记得将DropDownList1的AutoPostBack设为true。
下面的添加到contrlRepeater()中：
int pageall=pds.PageCount;
this.DropDownList1.Items.Clear();
for (int i = 1; i <= pageall; i++)
{
ListItem myli = new ListItem(i.ToString(), i.ToString());
myli.Enabled = true;
this.DropDownList1.Items.Add(myli);
}
this.DropDownList1.Enabled = true;
this.DropDownList1.AutoPostBack = true;
事件;
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
this.labPage.Text =this.DropDownList1.SelectedItem.Text;
this.contrlRepeater();
}
