asp.net - 单选按钮 onCheckedChagned 事件

Question

试图实现一个单选按钮onCheckedChanged事件但函数背后的代码没有触发可以有人向我指出我在下面的代码中到底做错了什么。

页面

<asp:RadioButton runat="server" checked="true" OnCheckedChanged="Check_Clicked"    AutoPostBack="true"   groupname="parent_category" id="rbCat1"  />
 <asp:RadioButton runat="server" checked="false" OnCheckedChanged="Check_Clicked"  AutoPostBack="true"   groupname="parent_category" id="rbCatCream"  />

代码背后

  Public Sub Check_Clicked(ByVal sender As System.Object, ByVal e As System.EventArgs)
    dim test as string =""
  end sub

先感谢您。

Answer 1

试试这个

 <asp:RadioButton runat="server" checked="true" OnCheckedChanged="Check_Clicked"    AutoPostBack="true"   groupname="parent_category" id="rbCat1"  />
 <asp:RadioButton runat="server"  OnCheckedChanged="Check_Clicked"  AutoPostBack="true"   groupname="parent_category" id="rbCatCream"  />


Protected Sub Check_Clicked(ByVal sender As System.Object, ByVal e As System.EventArgs)Handles rbCat1.CheckedChanged, rbCatCream.CheckedChanged
   dim test as string =""
end sub

Answer 2

试试这个。

  <asp:RadioButtonList ID="rdolist" AutoPostBack="true" runat="server" OnSelectedIndexChanged="rdolist_SelectedIndexChanged">
    <asp:ListItem Text="test" Value="test"></asp:ListItem>
    <asp:ListItem Text="test1" Value="test1"></asp:ListItem>
  </asp:RadioButtonList>

// on code behind
Protected Sub rdolist_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rdolist.SelectedIndexChanged
   // your code
end sub
