中继器控制链接按钮不起作用 [英] repeater control link button not working

问题描述

我的代码：

 <   asp：SqlDataSource     ID   =  dsCollections    runat   =  server   < span class =code-attribute> ConnectionString   =   <％ $ ConnectionStrings：csConnectionString ％>   
   
                  < span class =code-attribute>   SelectCommand   =  SELECT [CategName]，[Id] FROM [Category] >  <   / asp：SqlDataSource  >  
 <   asp：Repeater     ID   =  Repeater1   < span class =code-attribute> runat   =  server >  
 <   ItemTemplate  >  
 <  < span class =code-leadattribute> asp：LinkBut​​ton     ID   =  LinkBut​​ton1    runat   =  server    OnCommand   =  LinkBut​​ton1_Command < span class =code-attribute>   CommandName   =  MyUpdate    CommandArgument   = '  <％ #Eval（  CategName）％> ' >  LinkBut​​ton <   / asp：LinkBut​​ton  >  
  <   / ItemTemplate  >  
 <   / asp：Repeater  >  

< br $>


asp.net代码：

  protected   void  LinkBut​​ton1_Command（ object  sender，CommandEventArgs e）
 {
  if （e.CommandName ==   MyUpdate）
 {
 Response.Write（ 工作）; 
} 
} 

解决方案

ConnectionStrings：csConnectionString ％>

SelectCommand = SELECT [CategName]，[Id] FROM [Category] > < / asp：SqlDataSource >
< span class =code-keyword>< asp：Repeater ID = Repeater1 runat = 服务器 >
< span class =code-keyword>< ItemTemplate >
< asp：LinkBut​​ton ID = LinkBut​​ton1 runat = 服务器 OnCommand = LinkBut​​ton1_Command CommandName = MyUpdate CommandArgument =' <％ #Eval（ CategName）％> ' > LinkBut​​ton < / asp：LinkBut​​ton >
< / ItemTemplate >
< / asp：重复r >

asp.net代码：< br $> b $ b

 受保护  void  LinkBut​​ton1_Command（ object  sender，CommandEventArgs e）
 {
  if （ e.CommandName ==   MyUpdate）
 {
 Response.Write（   work）; 
} 
} 

我认为你应该绑定来自代码的数据...

因为它的工作..

 DataTable dt =  new  DataTable（）; 
 dt.Columns.Add（  CategName）; 
  for （ int  i =  0 ; i <   10 ; i ++）
 {
 dt.Rows .Add（  CategName + i）; 
} 
 Repeater1.DataSource = dt; 
 Repeater1.DataBind（）; 
 

如果那是一个Repeater Control，那么你可以尝试定义 Repeater.ItemCommand Event [ ^ ]。

my code:

<asp:SqlDataSource ID="dsCollections" runat="server" ConnectionString="<%$ ConnectionStrings:csConnectionString %>"

         SelectCommand="SELECT [CategName], [Id] FROM [Category]"></asp:SqlDataSource>
  <asp:Repeater ID="Repeater1" runat="server">
    <ItemTemplate>
        <asp:LinkButton ID="LinkButton1" runat="server" OnCommand="LinkButton1_Command" CommandName="MyUpdate" CommandArgument='<%# Eval("CategName") %>'>LinkButton</asp:LinkButton>
    </ItemTemplate>
</asp:Repeater>

asp.net code:

protected void LinkButton1_Command(object sender, CommandEventArgs e)
   {
       if (e.CommandName == "MyUpdate")
       {
           Response.Write("work");
       }
   }

解决方案

ConnectionStrings:csConnectionString %>" SelectCommand="SELECT [CategName], [Id] FROM [Category]"></asp:SqlDataSource> <asp:Repeater ID="Repeater1" runat="server"> <ItemTemplate> <asp:LinkButton ID="LinkButton1" runat="server" OnCommand="LinkButton1_Command" CommandName="MyUpdate" CommandArgument='<%# Eval("CategName") %>'>LinkButton</asp:LinkButton> </ItemTemplate> </asp:Repeater>

asp.net code:

protected void LinkButton1_Command(object sender, CommandEventArgs e)
   {
       if (e.CommandName == "MyUpdate")
       {
           Response.Write("work");
       }
   }

i think you should bind the data from code behind...
because its working..

DataTable dt = new DataTable();
           dt.Columns.Add("CategName");
           for (int i = 0; i < 10; i++)
           {
               dt.Rows.Add("CategName" + i);
           }
           Repeater1.DataSource = dt;
           Repeater1.DataBind();

If that is a Repeater Control, then you can try defining the Repeater.ItemCommand Event[^].
