Answer 1

SQL表EmpDetail根據您的情況可以嘗試下面的代碼

我希望它可以幫助你

protected void GridviewBind() 
{ 
    using (SqlConnection con = new SqlConnection("Data Source=RapidProgramming;Integrated Security=true;Initial Catalog=RPDB")) 
    { 
     con.Open(); 
     SqlCommand cmd = new SqlCommand("Select Name,Salary FROM YOUR TABLE", con); 
     SqlDataReader dr = cmd.ExecuteReader(); 
     GridView1.DataSource = dr; 
     GridView1.DataBind(); 
     con.Close(); 
    } 
} 

<asp:GridView ID="GridView1" runat="server" BackColor="White" 
       BorderColor="#3366CC" BorderStyle="None" 
       BorderWidth="1px" CellPadding="4" 
       style="text-align: center; margin-left: 409px" Width="350px"> 
    <FooterStyle BackColor="#99CCCC" ForeColor="#003399" /> 
    <HeaderStyle BackColor="#003399" Font-Bold="True" ForeColor="#CCCCFF" /> 
    <PagerStyle BackColor="#99CCCC" ForeColor="#003399" HorizontalAlign="Left" /> 
    <RowStyle BackColor="White" ForeColor="#003399" /> 
    <SelectedRowStyle BackColor="#009999" Font-Bold="True" ForeColor="#CCFF99" /> 
    <SortedAscendingCellStyle BackColor="#EDF6F6" /> 
    <SortedAscendingHeaderStyle BackColor="#0D4AC4" /> 
    <SortedDescendingCellStyle BackColor="#D6DFDF" /> 
    <SortedDescendingHeaderStyle BackColor="#002876" /> 
</asp:GridView>;

你可以簡單地使用SqlDataSource。您可以將SqlDataSource從它所說的Data，SqlDataSource的工具箱中移出。然後您將使用智能標籤配置數據源。然後使用gridview上的智能標記，選擇您放置在aspx頁面上的SqlDataSource。這非常快，需要很少或沒有編碼。 http://msdn.microsoft.com/En-us/Library/z72eefad.aspx這會告訴你更多一點。希望這可以幫助你！

爲了運行這些代碼，你需要與你更換的ConnectionString憑據myServerName \ myInstanceName，MYDATABASE，名爲myUsername，MYPASSWORD

using System.Data; 
using System.Data.SqlClient; 

string sConnectionString = @"Data Source=myServerName\myInstanceName;Initial Catalog=myDataBase;User ID=myUsername;Password=myPassword;"; 

protected void Page_Load(object sender, EventArgs e){ 
    if(!IsPostBack) 
     BindGridView(); 
} 

private void BindGridView() {    
    DataTable dt = new DataTable();   
    SqlConnection con = null;   

    try { 
     string sQuery = "SELECT ID, Name, Salary FROM EmpDetail"; 

     SqlConnection con = new SqlConnection(sConnectionString); 
     con.Open(); 
     SqlCommand cmd = new SqlCommand(sQuery, con); 
     SqlDataReader sdr = cmd.ExecuteReader(); 

     dt.Load(sdr); 
     Gridview1.DataSource = dt; 
     Gridview1.DataBind(); 
    } 
    catch{ } 
    finally{ 
     dt.Dispose(); 
     con.Close(); 
    } 
}

<asp:GridView ID="GridView1" runat="server"> 
</asp:GridView> 

protected void Page_Load(object sender, EventArgs e) { 
    if (!IsPostBack) { 
     bindData(); 
    } 
} 

public void bindData() { 
     SqlConnection con=new SqlCponnection(ConnectionStrings); 
     SqlDataAdapter da = new SqlDataAdapter("select * from Your TableName", con); 
     DataSet ds = new DataSet(); 
     try { 
      da.Fill(ds, "YourTableName"); 
      GridView1.DataSource = ds; 
      GridView1.DataBind(); 
     } catch (Exception e) { 
      Response.Write(e.Message); 
     } finally { 
      ds.Dispose(); 
      da.Dispose(); 
      con.Dispose(); 
     }

use Class7917 
select * from Emp 
alter table Emp add images varchar(100) 
sp_helptext 'usp_emp_insert_update' 
alter proc usp_emp_insert_update 
@empid int, 
@name varchar(50), 
@cid int, 
@sid int, 
@dob datetime, 
@isactive int, 
@hobbies varchar(100), 
@images varchar(100) 
as 
begin 
if(@empid=0) 
    begin 
    insert into Emp(Name,cid,sid,dob,isactive,hobbies,images) 
    values(@Name,@cid,@sid,@dob,@isactive,@hobbies,@images) 
    end 
else 
    begin 
    update Emp set Name=@name,cid=@cid,sid=@sid, 
    dob=@dob,isactive=@isactive,hobbies=@hobbies,images=@images 
    where EmpID=@empid 
    end 
end 
truncate table Emp

試試這個....

protected void Page_Load(object sender, EventArgs e) 
{ 
    using (var conn = new SqlConnection(ConfigurationManager.ConnectionStrings["myDB"].ConnectionString)) 
    { 
     SqlCommand cmd = new SqlCommand("select * from Table1", conn); 
     conn.Open(); 
     SqlDataReader dr = cmd.ExecuteReader(); 
     GridView1.DataSource = dr; 
     GridView1.DataBind(); 
     conn.Close(); 
    } 

} 

<div> 
    <asp:GridView ID="GridView1" runat="server"></asp:GridView> 
</div>
