使用的System.Web;
使用System.Web.UI程序;
使用System.Web.UI.WebControls;
命名空间LibrarySystem.AdminPage
{
    公共部分类ManageBooks：System.Web.UI.Page
    {
        保护无效的Page_Load（对象发件人，EventArgs的发送）
        {
            如果（FormView1.CurrentMode == FormViewMode.Insert）
            {
                文本框dateadded = FormView1.FindControl（dateaddedTextBox）的文本框;
                    dateadded.Text = DateTime.Now.ToString（D）;

解决方案

您必须使用数据绑定事件为... 

 保护无效FormView1_DataBound（对象发件人，EventArgs的发送）
{
    如果（FormView1.CurrentMode == FormViewMode.Insert）
    {
        文本框dateadded = FormView1.FindControl（dateaddedTextBox）的文本框;
        dateadded.Text = DateTime.Now.ToString（D）;
    }
}

编辑：您需要通过你的日期列在DetailsView的插入方法

 保护无效DetailsView1_ItemInserting（对象发件人，DetailsViewInsertEventArgs E）
{
    e.Values​​ [DateColumnName] =（（文本框）DetailsView1.FindControl（dateaddedTextBox））文本。
}

I want to put the current date in my formview 'dateadded' but its not showing when I load it in the browser. I'm using code behind but how can I display it with date and time?

Here's a my code behind.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;


namespace LibrarySystem.AdminPage
{
    public partial class ManageBooks : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if(FormView1.CurrentMode == FormViewMode.Insert)
            {
                TextBox dateadded = FormView1.FindControl("dateaddedTextBox") as TextBox;
                    dateadded.Text = DateTime.Now.ToString("d");
            }
        }
    }
}

You have to use the Databound event for that...

 protected void FormView1_DataBound(object sender, EventArgs e)
{
    if (FormView1.CurrentMode == FormViewMode.Insert)
    {
        TextBox dateadded = FormView1.FindControl("dateaddedTextBox") as TextBox;
        dateadded.Text = DateTime.Now.ToString("d");
    }
}

Edit: You need to pass your Date Column in the inserting method of the DetailsView

protected void DetailsView1_ItemInserting(object sender, DetailsViewInsertEventArgs e)
{
    e.Values["DateColumnName"] = ((TextBox)DetailsView1.FindControl("dateaddedTextBox")).Text;
}

这篇关于设置当前日期的FormView的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
