有什么想法吗？我不知道为什么，但是通过将
btnSearchCausesValidationtrue<asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click"
CausesValidation="true" />
您需要将ValidationGroup添加到验证控件中，以便每个验证组可以独立于特定页面上的其他验证组执行验证。更多你可以在这里阅读 这是带有组验证的代码。您可以将其更改为您的环境

希望这能有所帮助。请提供更多服务器和客户端代码/html。1]删除或注释RangeValidator1和RangeValidator2，并尝试从日历中选择日期-您是否看到相同的行为？删除范围验证程序仍然会产生相同的奇怪行为，即必须滑动按钮两次才能接合。我尝试了此操作，如果我将其设置为true按钮根本不接合，如果我一起移除属性，按钮将不接合
