將數據綁定到gridview。如何使用分頁？

Question

這是彈出一個異常，說我不能在服務器端使用分頁。

conn.Open(); 
string querstring = "select * from gt_transaction_log where LogTimeStamp between '2013-09-19 07:06:00.077' and '2013-09-19 10:28:25.163' "; 
SqlCommand cmd = new SqlCommand(querstring, conn); 
GridView1.EmptyDataText = "no record found"; 
GridView1.DataSource = cmd.ExecuteReader(); 
GridView1.DataBind(); 

GridView1.AllowPaging = true; 
GridView1.PageSize = 5; 

Answer 1

不能使用分頁與DataReader。所以，問題是這一行：

GridView1.DataSource = cmd.ExecuteReader();

你應該使用Dataset或Datatable使用DataAdapter填充GridView控件。

例子：

//使用DataTable

string querstring = "select * from gt_transaction_log where LogTimeStamp between 
        '2013-09-19 07:06:00.077' and '2013-09-19 10:28:25.163' "; 
SqlDataAdapter adapter = new SqlDataAdapter(querstring , conn); 
DataTable dt = new DataTable(); 
adapter.Fill(dt); 
GridView1.DataSource=dt; 
GridView1.DataBind(); 

//使用DataSet

string querstring = "select * from gt_transaction_log where LogTimeStamp between 
        '2013-09-19 07:06:00.077' and '2013-09-19 10:28:25.163' "; 
SqlDataAdapter adapter = new SqlDataAdapter(querstring , conn); 
DataSet ds = new DataSet(); 
adapter.Fill(ds, "Table_Name"); // you can supply a table name 
GridView1.DataSource=ds; 
GridView1.DataBind(); 

Answer 2

在設計視圖，單擊的GridView>允許分頁 或使用SqlDataSource的代替，然後讓分頁

Answer 3

，如果你想在頁面的UI分頁必須指定，那就是：

<asp:GridView ID="grid" runat="server" AllowPaging="true" PageSize="5" OnPageIndexChanging="grid_PageIndexChanging" /> 

然後在CS文件：

protected void grid_PageIndexChanging(object sender, GridViewPageEventArgs e) 
    { 
     try 
     { 
      grid.PageIndex = e.NewPageIndex; 
      BindGrid(); 
     } 
     catch (Exception ex) 
     { 
     } 
    } 

凡BindGrid（）方法是在其中我們結合電網的一個。

您可以嘗試使用此代碼.......

String constring = "Data Source=dsdsdsds;Initial Catalog=table;User Id=uid;Password=pass"; 
SqlConnection conqav = new SqlConnection(constring); 
String takeffty = "select top 10 * from table"; 
conqav.Open(); 
SqlCommand comqav = new SqlCommand(takeffty,conqav); 
GridView1.DataSource = comqav.ExecuteReader(); 
GridView1.DataBind(); 
conqav.Close();
