在 ASP.net 中填充 SQL 的 GridView 的日期格式 - 非绑定字段
Date Format to a GridView populated with SQL in ASP.net - NOT boundfield
这是创建 GridView 的代码,其他一切都是用 C# 发生的,我的意思是用 C# 代码填充:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="STANDBY_JOURNALS Email.aspx.cs" Inherits="STANDBY_JOURNALS_Email.STANDBY_JOURNALS_Email" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="SQL" OnClick="Button1_Click" />
<asp:Button ID="Button2" runat="server" Text="SEND" OnClick="Button2_Click" />
<br />
<asp:GridView ID="GridView1" runat="server" Font-Size="Smaller">
</asp:GridView>
</div>
</form>
</body>
</html>
我需要将日期格式添加到此 GridView,但如果我尝试使用 BOUNDFIELD
,它会在 table 的开头创建一列,如下所示:
<asp:GridView ID="GridView1" runat="server" Font-Size="Smaller">
<Columns>
<asp:BoundField DataField="Journal Date" DataFormatString="{0:MMMM d, yyyy}" />
</Columns>
</asp:GridView>
这是我的代码:
using System;

using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net;
using System.Net.Mail;

using System.Data.SqlClient;
using System.IO;
namespace STANDBY_JOURNALS_Email
{
public partial class STANDBY_JOURNALS_Email : System.Web.UI.Page
{
SqlConnection vid = new SqlConnection("Data Source=xxxxxxxx; Initial Catalog=xxxxxxxxxxx; User id=xxxxxx; Password=xxxxxxx");
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
string sqlquery1 = "SELECT * FROM DBO.STANDBY_JOURNALS_DQMS WHERE [Ledger Grp] IN ('ACTUALS','GRP_FXRATE','CONSEGRP') AND [Source] = 'CON' OR [Source] LIKE 'Q%' ORDER BY [Source], [SystemDateTime],[SystemTime] ASC";
String str = sqlquery1;
SqlCommand xp = new SqlCommand(str, vid);
vid.Open();
xp.ExecuteNonQuery();
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = xp;
DataSet ds = new DataSet();
da.Fill(ds, "Name");
GridView1.DataSource = ds;
GridView1.DataBind();
vid.Close();
}
public override void VerifyRenderingInServerForm(Control control)
{
/* Verifies that the control is rendered */
}
protected void Button2_Click(object sender, EventArgs e)
{
using (StringWriter sw = new StringWriter())
{
using (HtmlTextWriter hw = new HtmlTextWriter(sw))
{
String EmailFrom = "xxxxxx@xxxxx.co.nz";
String EmailTo = "xxxxxx@xxxxx.co.nz";
String EmailSubject = "this is a subject";
//String EmailBody = "Cuerpo del Mensaje";
GridView1.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
MailMessage mm = new MailMessage(EmailFrom, EmailTo);
mm.Subject = EmailSubject;
mm.Body = "Report:<hr />" + sw.ToString(); ;
mm.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "XXXXXXXXXXXXXX";
smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
smtp.Port = 25;
smtp.Timeout = 20000;
smtp.Send(mm);
}
}
}
}
}
任何人都可以帮助了解如何影响使用 GridView 创建的 table 中的列?
将 GridView 的 AutoGenerateColumns
属性 设置为 false
(我认为这是您正在寻找的唯一解决方案)并为所有必需的列添加 BoundFields。
或者,如果您使用的是 TemplateFields,则可以选择为 TemplateField
设置日期格式。无需添加 BoundField
如:
<asp:TemplateField ItemStyle-Width = "100px" HeaderText = "date"
SortExpression="date" >
<ItemTemplate>
<asp:Label ID="lblreceived_at" runat="server"
Text='<%# Eval("date","{0:d}")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
在 BoudField 中,试试这个格式:
DataFormatString="{0:dd/MM/yyyy}"
输出:
01/06/2017 00:00:00
最简单的方法就是在查询中使用 SQL MID()
,
SELECT MID(Journal_Date,1,8) AS JD FROM DBO.STANDBY_JOURNALS_DQMS
它会给你
01/06/17
如果您在 SQL 查询中添加以下 Convert
函数,您的目的就会达到。例如:
Select CONVERT(varchar,YOUR_DATE_COLUMN,107) as JournalDate, * From YOUR_TABLE_NAME
