How to define form field prefix in ASP.NET MVC

阅读更多关于 How to define form field prefix in ASP.NET MVC

问题 I am attempting to render a composite ProductCatalog view in ASP.NET MVC. This requires that I render multiple Product views per page. Each product view is a separate form. I need the form fields to have a prefix based on the id, so that I don't have duplicate IDs in the rendered document. Is there a way to define a prefix to be applied to all the form fields that are generated by the Html Extensions, or do I need to build this out manually? 回答1: Yes, you can define a prefix for the controls

Disable or enable Submit button on Checkbox checked event

阅读更多关于 Disable or enable Submit button on Checkbox checked event

问题 I want something like this but with a slight change. I want a Button to be enabled or disabled on Checkbox checked event, i.e. when checkbox is checked then and then only button should be enabled otherwise it is disabled. This should be done using jQuery Code not JavaScript. As this is MVC form so there is no Form ID. 回答1: $(function() { $('#id_of_your_checkbox').click(function() { if ($(this).is(':checked')) { $('#id_of_your_button').attr('disabled', 'disabled'); } else { $('#id_of_your

How to use ReportViewer 2010 in MVC.NET 2

阅读更多关于 How to use ReportViewer 2010 in MVC.NET 2

问题 Basically I want to know how to embed a report into MVC.Net 2. 回答1: I did the question, because there's not enough information on the web, or the information is not that complete so you can start working. The first thing you have to know is that the report viewer is a webcontrol so you can't use it on MVC, so first thing you have to do is create a web form so you can add the report viewer. In the example I've done I'm using Visual Studio 2010. The webform looks like this: <html xmlns="http:/

阅读更多关于 Change default browser in Visual Studio 2010 RC

问题 In Visual Studio 2010 (RC) there is no longer a "browse with" context menu when right clicking .aspx pages. How can you change the default browser now? By default it seems to use the operating system default browser, but I would prefer to use IE when debugging ASP.net apps. (I am testing this with ASP.net MVC 2) 回答1: There is no "Browse With" option on the .aspx Views in an MVC project as they are not meant to be directly browseable. What I tend to do is add a Default.aspx webform in the root

问题 I have a new WIndows Server 2008 R2 x64 DataCentre with Framework 3.5 SP1 and Framework 4 installed.

Foreach on IEnumerable property and CheckBoxFor in ASP.Net MVC

阅读更多关于 Foreach on IEnumerable property and CheckBoxFor in ASP.Net MVC

问题 I believe this question applies to any of the "For" Html helpers, but my specific problem is using CheckBoxFor... I have a model that is of type IEnumerable, where rights is a simple POCO. This model is actually a property of a bigger model that I created an EditorTemplate for. Here is the bigger picture of my model: public class bigmodel { public string Title {get; set;} public string Description {get; set;} [UIHint("ListRights")] public IEnumerable<rights> Rights {get;set;} } public class
