wpf - Is this a crazy way to handle multi Validation types with IDataError and WPF?

We are using the standard method for our controls to report broken BO rules. This is done via the interface IDataError in our BO’s and in XAML the control is bound to the BO’s property etc. This approach works OK. But we need to show 2 types of visuals in the UI depending on the type (or category if you like) of the invalidation error. If it’s a required field then we show a CueBanner (water mark) but for other types we change the colour of the controls boarder. In both scenarios we set the tool type of the error message.

The Problem with IDataError is that it doesn’t support a method/property to distinguish between error types.

The only way I can do that is by examining the error text, required field text must contain the key word “required”. The following approach doesn’t feel right but it’s the only way I can determine the type of error and then deal with it accordingly. All required field rules must have as part of the error text “required field”. To make this all work I have created a custom dependency property called ErrorMessage. In my ResourceDictionary I have a Style.Trigger for Validation.HasError. In there I set my dependency properties value to the ErrorContent. Now when my dependency properties value changes I can examine the text and set the Validation.SetErrorTemplate( myControl, newErrorTemplate) to the template to suit the error type. I have to wire up a few events to the control such as lost and got focus to manage removing or adding the cueBanner template but the whole thing will work. It’s just that I’m not sure it’s the best way to do it.

PS. When I set the ErrorTemplate i’m doing this in code, thats building and adding it. Is there a way to point Validation.SetErrorTemplate to a static resource keeping in mind that I need to switch between at least 2 types?

Your thoughts please..

javascript - JQuery.Validate 插件可以阻止提交 Ajax 表单吗

我正在使用 JQuery 表单插件 ( http://malsup.com/jquery/form/ ) 来处理表单的 ajax 提交。我还插入了 JQuery.Validate ( http://docs.jquery.com/Plugins/Validation ) 以进行客户端验证。

我所看到的是，当我期望验证失败时，它不会阻止表单提交。当我使用传统表单（即非ajax）时，验证失败完全阻止了表单提交......这是我想要的行为。

我知道验证已正确连接，因为在 ajax 提交发生后仍会出现验证消息。

那么我错过了什么阻止了我想要的行为？下面的示例代码......

asp.net - 如何动态设置 ValidationGroup

我有一个带有 2 个用户控件 (.ascx) 的 ASP.NET 2.0 网页。每个 UserControl 都包含一堆验证器。在页面上放置 ValidationSummary 将显示两个 UserControl 的所有验证错误。在每个 UserControl 中放置一个 ValidationSummary 将显示两个控件的所有错误两次。

我想要的是每个 UserControl 的 ValidationSummary，只显示该 UserControl 上的错误。

我试图通过在每个用户控件上动态设置验证器的 ValidationGroup 属性来解决这个问题。这样每个验证摘要应该只显示其用户控件的错误。我用过这段代码：

然而，这似乎禁用了客户端和服务器端验证，因为提交表单时不会发生验证。

帮助？
