使用压光机选择器后按钮控制不接合
使用压光机选择器后按钮控制不接合
提问于 2012-06-07 22:08:37
我有一个日历选择器，看起来像
<asp:ImageButton ID="calStartImage" runat="server" ImageUrl="../images/SmallCalendar.gif"
AlternateText="Please select start date" />
<ajaxToolkit:CalendarExtender ID="calStartDate" runat="server" TargetControlID="txtStartDate"
Format="MM/dd/yyyy" PopupButtonID="calStartImage" />还有一个搜索按钮，如下所示
<asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click"
CausesValidation="false" />当我从日历中选择一个日期并按下Search..The first time btnSearch_Click doesnt fire..If时，我再次单击Search，它工作正常。因此，在单击事件生效之前，我必须单击搜索按钮两次。只有当我从日历控件中选择一个日期时，才会发生这种情况。
下面是完整的控制：
<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">

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。您可以在此处阅读更多内容Specifying Validation Groups
这是你使用组验证的代码。您可以将其更改为您的环境。

我不知道为什么，但是可以通过将btnSearch的CausesValidation属性设置为true来解决您的问题
<asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click"
CausesValidation="true" />页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
