如何在C＃，XML，.NET转发器控件中获取我的标签的loweste值 [英] How do get the loweste value of my label in C#, XML, .NET repeater control

问题描述

我试图通过多重标签从转发器控件中获取loweste标签值。

标签<％ #XPath（  TourStatusNo）％> '> 

前端

< asp：Repeater ID =CategoryRepeaterOnItemDataBound = CategoryRepeater_ItemDataBoundrunat =serverDataSourceID =XmlDataSource1> 
< itemtemplate> 
 
< h3 class =h3DAy> 
< div style =text-align：left;> 
<％＃XPath（@ day）％>：<％＃XPath（@ date）％> 
 < asp：Label Visible =falseID =lblIconrunat =server/>  
 
 
值：< asp：标签runat =serverID =lblNoText ='<％＃XPath（TourStatusNo）％>' > 
 
 
< / div> 
< / h3> 
 

C＃

我知道如何获得价值可能无法弄清楚我是如何获得TourStatusN的loveste价值

 Repeater repChild =（Repeater）e.Item.FindControl（   childRepeater）; 
 
 
 
标签lblIcon =（标签）e.Item.FindControl（  lblIcon）; 
 Label lblNo =（Label）e.Item.FindControl（  lblNo）; 
 
  foreach （RepeaterItem item  in  repChild.Items）
 { 
 
 
 
 
 
 $ b标签lblTekst1 =（标签）item.FindControl（ < span class =code-string> lblHeadChild）; 
标签lblNoNest =（标签）item.FindControl（  lblStatusNo）; 
 
  //  这里我想从我的lblNoNest获得最低值并读入我的父母转发器lblNo。我现在不知道如何获得最低价值。 
 
 
}}< blockquote  class  =   quote>< div  class  =   op> Quote：< /   div  >  

Xml文件在侧面游览中的节点TourStatusNo，我希望得到最低值，并将其读入我的父转发器头。它的b $ b

我的尝试：



我尝试使用Xpath min和max但不太擅长，我试着计算C＃...

解决方案

您好



尝试此解决方案



声明一个全局变量，如

  var  minTourStatusNo =  0 ; 

检查每个循环中minTourStatusNo值的值，如

 Repeater repChild =（Repeater）e.Item.FindControl（  childRepeater ）; 
 
 
 
标签lblIcon =（标签）e.Item.FindControl（  lblIcon）; 
 Label lblNo =（Label）e.Item.FindControl（  lblNo）; 
 
  foreach （RepeaterItem item  in  repChild.Items）
 { 
 
 
 
 
 
 $ b标签lblTekst1 =（标签）item.FindControl（ < span class =code-string> lblHeadChild）; 
标签lblNoNest =（标签）item.FindControl（  lblStatusNo）; 
  //  你可以转换你想要的数据类型，如双十进制int64等。 
  if （Convert.ToInt32（lblNoNest.Text）< mintourstatusno）
 minTourStatusNo = Convert.ToInt32（lblNoNest.Text）; 
  //  这里我想从我的lblNoNest获取最低值并读入我的父转发器lblNo。我现在不知道如何获得最低价值。 
 
 
}}< blockquote  class  =   quote>< div  class  =   op> Quote：<％= minTourStatusNo.ToString（）％>  < /   div  >  
 < /   blockquote  >  

I am trying to get the loweste label value from repeater control with multible labels.

labels<%# XPath("TourStatusNo") %>'>

frontend

<asp:Repeater ID="CategoryRepeater" OnItemDataBound="CategoryRepeater_ItemDataBound" runat="server" DataSourceID="XmlDataSource1">
    <itemtemplate>

        <h3 class="h3DAy">
            <div style="text-align: left;">
                  <%#XPath ("@day")%>:  <%#XPath ("@date")%>
               <asp:Label Visible="false" ID="lblIcon" runat="server" /> 


                            Value:<asp:Label runat="server" ID="lblNo" Text='<%# XPath("TourStatusNo") %>'>


            </div>
        </h3>

C#
I know how to get the values can just not figure out how i get the loveste value of TourStatusNo

            Repeater repChild = (Repeater)e.Item.FindControl("childRepeater");



            Label lblIcon = (Label)e.Item.FindControl("lblIcon");
            Label lblNo = (Label)e.Item.FindControl("lblNo");

            foreach (RepeaterItem item in repChild.Items)
            {

                
               


                Label lblTekst1 = (Label)item.FindControl("lblHeadChild");
                Label lblNoNest = (Label)item.FindControl("lblStatusNo");

               // here i want to get the lowest value from my lblNoNest and read into my parent repeater lblNo. Just dont now how i only get the lowest value.

What I have tried:

I try Xpath min and max but not so good at it, i tryede to count in C#...

解决方案

Hi

try this solution

Declare a global variable like

var minTourStatusNo=0;

check the value of minTourStatusNo value in each loop like

 Repeater repChild = (Repeater)e.Item.FindControl("childRepeater");
 

 
            Label lblIcon = (Label)e.Item.FindControl("lblIcon");
            Label lblNo = (Label)e.Item.FindControl("lblNo");
 
            foreach (RepeaterItem item in repChild.Items)
            {
 
                
               
 

                Label lblTekst1 = (Label)item.FindControl("lblHeadChild");
                Label lblNoNest = (Label)item.FindControl("lblStatusNo");
//you can convert what data type you want like double decimal int64 etc.
              if(Convert.ToInt32(lblNoNest.Text) <mintourstatusno)
                   minTourStatusNo=Convert.ToInt32(lblNoNest.Text);
               // here i want to get the lowest value from my lblNoNest and read into my parent repeater lblNo. Just dont now how i only get the lowest value.

 
}}<blockquote class="quote"><div class="op">Quote:<% =minTourStatusNo.ToString()%></div>
