如何在asp.net中验证转发器控件 [英] how to validate the repeater control in asp.net

问题描述

源页面代码如下

 <   div  >  
 <  < span class =code-leadattribute> asp：Repeater     ID   =  Repeater1    runat   =  server >  
 <   HeaderTemplate  > ;  
 <   table     border   =  0    width   =  600px    cellpadding   =  2    cellspacing   =  1   样式  =  border：1px solid maroon ; >  
 <   tr     bgcolor   =  maroon >  
 <   th  >  
 course <   / th  >  
 <   th  >  
 Courseamt​​ <   / th  >  
 <   th  >  
 Coursedate <   / th  >  
 
 <   / tr   >  
 <   / HeaderTemplate  &克t;  
 <   itemtemplate  >  
 <   tr  >  
 
 <   td     width   =  100 >  
 <％＃DataBinder.Eval（ Container，  DataItem.course）％> 
 <   / td  >  
 <   td  >  
 <％＃DataBinder.Eval（Container，  DataItem.Courseamt​​）％> 
 <   / td  >  
 <   td     width   =  150 >  
 <％＃DataBinder.Eval（Container，  DataItem.Coursedate）％> 
 <   / td  >  
 
 <   / tr  >  
 <   / itemtemplate  >  
 <   alternatingitemtemplate  >  
 <   tr     bgcolor   = ＃e8e8e8 >  
 <   td     width   =  100 >  
 <％＃DataBinder.Eval（Container，  DataItem.course）％> 
 <   / td  >  
 <   td  >  
 <％＃DataBinder.Eval（Container，  DataItem.Courseamt​​）％> 
 <   / td  >  
 <   td     width   =  150 >  
 <％＃DataBinder.Eval（Container，  DataItem.Coursedate）％> 
 <   / td  > > 
 <   / tr  >  
 <   / alternatingitemtemplate  >  
 <   footertemplate  > ;  
 <   / footertemplate  >  <   / table  > ;  
 
 
 
 <   asp：Button     ID   = < span class =code-keyword>提交    runat   =  server    /  >  
 
 <   div     style   =  font-size：14px;颜色：海军 >  
 <   / div  >  
 <   / div  >  

我的代码如下

 受保护  void  Page_Load（ object  sender，EventArgs e）
 {
 SqlConnection con =  new  SqlConnection（  Server =（local）; initial catalog = Himt_Testing; Trusted_Connection = True）; 
  string  str; 
 SqlCommand cmd =  new  SqlCommand（  select * from Tb_Course_details，con）; 
 cmd.Connection.Open（）; 
 Repeater1.DataSource = cmd.ExecuteReader（）; 
 Repeater1.DataBind（）; 
 cmd.Connection.Close（）; 
} 

当我运行上面的代码时，在转发器控件中显示如下输出



< pre lang =text> Coursename Amount Coursedate

RPST 400 29 Apr 14
RPSCRB 500 30 Apr 14

然后我有一个叫做提交的按钮。



当我点击提交按钮时，我必须显示RPST和RPSCRB课程必须是同一日期的消息。



我怎么能用转发器控制来验证。







已添加 pre 标签。

使用复选框验证转发器控件 [ ^ ]

http://www.chrislord.me/blog/aspnet-validation-control-inside-a-repeater-or- listview / [ ^ ]

Source page code as follows

<div>
<asp:Repeater ID="Repeater1" runat="server">
<HeaderTemplate>
<table border="0" width="600px" cellpadding="2" cellspacing="1" style="border: 1px solid maroon;">
<tr bgcolor="maroon">
<th>
course</th>
<th>
Courseamt</th>
<th>
Coursedate</th>

</tr>
</HeaderTemplate>
<itemtemplate>
<tr>

<td width="100">
<%# DataBinder.Eval(Container, "DataItem.course")%>
</td>
<td>
<%# DataBinder.Eval(Container, "DataItem.Courseamt")%>
</td>
<td width="150">
<%# DataBinder.Eval(Container, "DataItem.Coursedate")%>
</td>

</tr>
</itemtemplate>
<alternatingitemtemplate>
<tr bgcolor="#e8e8e8">
<td width="100">
<%# DataBinder.Eval(Container, "DataItem.course")%>
</td>
<td>
<%# DataBinder.Eval(Container, "DataItem.Courseamt")%>
</td>
<td width="150">
<%# DataBinder.Eval(Container, "DataItem.Coursedate")%>
</td>>
</tr>
</alternatingitemtemplate>
<footertemplate>
</footertemplate></table>


       
    <asp:Button ID="Submit" runat="server" />
    
<div style="font-size:14px; color:Navy">
     </div>
</div>

My code as follows

protected void Page_Load(object sender, EventArgs e)
{
    SqlConnection con = new SqlConnection("Server=(local);initial catalog=Himt_Testing;Trusted_Connection=True");
    string str;
    SqlCommand cmd = new SqlCommand("select *  from Tb_Course_details", con);
    cmd.Connection.Open();
    Repeater1.DataSource = cmd.ExecuteReader();
    Repeater1.DataBind();
    cmd.Connection.Close();
}

when i run the above code shows output as follows in repeater control

Coursename   Amount   Coursedate

RPST       400       29 Apr 14
RPSCRB     500       30 Apr 14

Then i have one button called Submit.

When i click submit button,i have to show the message the RPST and RPSCRB course must be same date.

for that how can i validate using repeater control.
