ASP.NET - 控制事件不在Repeater内部触发

<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand">

<asp:Button ID="Button1" runat="server" CommandName="MyCommand" Text="Click Me" />

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    if (e.CommandName == "MyCommand")
    {
        // 在这里处理事件逻辑
    }
}
