Repeater分页显示最普通的方法2<转>

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();
