Radiobutton onCheckedChagned事件

Question

試圖實現一個單選按鈕onCheckedChanged事件，但代碼後面的函數不能解僱有人能告訴我什麼我做錯了下面的代碼。

ASPX頁面

<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" /> 

代碼隱藏

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

預先感謝您。

Answer 1

試試這個

<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

試試這個。

<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
