文本框在ASP.NET中输入数据所面临的问题 [英] problem facing with Textboxes entering data in ASP.NET

问题描述

Hello Frnds！



正在使用c＃SqlServer 2005处理asp.net项目。



我的网页上有10个文本框和一个提交按钮...这用于保存数据库中输入的数据....它的工作正常。



我的要求是：



来自10个文本框我将只输入7个文本框....前3个文本框将照常输入每个条目。



只有一次我会进入前3个texbox ...而nextTime我将进入其他7个文本框..我不想进入前3个tbox。



前3个文本框数据对所有人来说都是通用的。



所以请帮我怎么做？



谢谢

解决方案

在你的页面加载事件中，只要它是回发就设置文本框的值 - 所以第一次它们将为空并随后将值设置为先前提交的值

我假设前3个文本框将具有公共值或默认值。如果是这种情况，为什么你甚至需要网页中的那3个文本框？



只保留7个文本框，输入您想要的数据。提交时包括在接下来的7个文本框中输入的前3个默认值和值，然后将它们保存到数据库中。

这就是你如何管理它或你想要它的方式。我给出代码示例of vb.net

 受保护的  Sub  btnSendMail_ServerClick（ ByVal  sender 作为 对象，< span class =code-keyword> ByVal  e  As  System.EventArgs）句柄 btnSendMail .ServerClick 
 ' 在插入数据库之前保存在viewstate中，如下所示 
 ViewState（   txt1）= txtCcMail.Text 
  ' 将您的代码插入到数据库中e  
 ''' ''''''''''
  ' 一旦插入数据库，将viewstate值分配回受尊重的文本框并清除其他文本框 
 txttoMail.Text = ViewState（  txt1）
 结束  Sub  

快乐编码

Hello Frnds !

am working on asp.net project using c# SqlServer 2005.

I have 10 Textboxes and a submit button on my webpage...this is use to save the data entered in database....its works fine.

My requirement is :

from total 10 textboxes i will enter only in 7 textboxes.... the first 3 textboxes will be as usual for every entry.

only once i will enter in first 3 texboxes...and nextTime i will enter in other 7 textboxes..i dont want to enter in first 3 tboxes.

the first 3 textboxes data will be common to all.

so please help me how to do this ?

Thanks

解决方案

In your page load event, set the value of the textboxes whenever it''s a postback - so the first time they will be empty and subsequently you set the values to whatever was submitted previously

I am assuming that first 3 textboxes will have common or default values. If that is the case, why do you even need those 3 textboxes in the webpage?

Keep only 7 textboxes, enter the data you want. While submitting include first 3 default values and values entered in next 7 textboxes, then save them into database.

this is just how you manage it or how you want it.I am give code example of vb.net

Protected Sub btnSendMail_ServerClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSendMail.ServerClick
'before inserting to database save in viewstate as follows
        ViewState("txt1") = txtCcMail.Text
'put your code to insert into database
''''''''''''''''
'once you inserted to database assign viewstate value back to respected textbox and clear other textboxes
        txttoMail.Text = ViewState("txt1")
    End Sub

Happy coding
