Repeater分页显示

简单的说，先从控件工具箱中拖入两个label（currten page当前页，count page总页），四个linkbuttion（首/下页/上页/尾页）。
无非就是+1 -1 的问题，

附:pb.returnDs(根据SQL语句返回dataSet数据集.temptable表)
public DataSet returnDs(string sqlStr)
{

DataSet ds = new DataSet();
try
{
//conn.Open();
SqlCommand comm = new SqlCommand(sqlStr, conn);
comm.CommandTimeout = 20;
this.conn.Open();
SqlDataAdapter sda = new SqlDataAdapter(comm);
sda.Fill(ds, "temptable");
return ds;
conn.Close(); conn.Dispose(); comm.Dispose();

}
catch (Exception e)
{
throw (e);
// ds = null;
return ds;
}
finally
{
this.conn.Close();
}
