ASP.NET Dynamic Data PRO and CONS

由 余生颓废 提交于 2019-12-10 01:58:58
问题 I heard about ASP.NET Dynamic Data in ASP.NET 4. I would like to know if you have implemented in real scenario web application and your opinions, specially in terms of customization. Some questions: Can I Use custom logic to validate Fields? Is it possible add logic when User press for example a DELETE button for a specific Table? As at a first look, it seems very easy build Scaffolding but any Cons? Thanks for your time! Regards 回答1: I've mostly used Dynamic Data to create "developer only"

问题 There is a lot of information about how to implement and customize scaffolding with Dynamic Data and ASP.NET MVC. What exactly is the definition of scaffolding when used in this context? 回答1: It means that the Dynamic Data framework will auto-generate a set of routes based on the table names in a data model (e.g. a Linq to SQL data context), and a predefined set of operations (essentially CRUD). When you e.g. visit http://example.com/Products/Details.aspx , where "Products" is the name of a

ASP.NET Dynamic Data DisplayColumn Attribute Causing Sorting Issue

由 我只是一个虾纸丫 提交于 2019-12-05 18:24:31
Using ASP.NET Dynamic Data with a LINQ to SQL DataContext from the Northwind Database... When I add a DisplayColumn Attribute to one of my LINQ to SQL entity classes and reference a property from my custom code in the partial class, I lose the ability to sort by that column in the generated GridViews . I continue to lose the ability to sort even if I reference a non-custom property as the sortColumn . Why is this happening? Example Code: [DisplayColumn("LastNameFirstName", "LastName", false)] public partial class Employee { public string LastNameFirstName { get { return LastName + ", " +

Do you think ASP.Net Dynamic Data is worth it?

At the risk of sounding misinformed, I'm under the belief that this is basically useful for RAD and fast sketching of an application. It feels somewhat Ruby-esque in the sense that it scaffolds pretty much everything you need from a CRUD application. Easier work for us, right; and most people are none the wiser. I'm fairly green in the workplace, I just start working at an actual job as a developer (cubicles and free coffee) so my opinions might be a bit on the green side, but I'd love some comments from more senior people. Is this somewhere between MVC2(basic scaffolding) and Microsoft

How to build an IEnumerable<int>.Contains() Expression?

I'm currently working with ASP Dynamic Data for the first time and I'm trying to build a filter. Our users have a need to locate items in a list based upon whether or not the item is a child of a selected parent (our items can have more than one parent). The items in question are Segments and each Segment has a property called RouteIds, of type IEnumerable, which is a collection of all of the Segment's parent Ids. I've gotten to this point in overriding the GetQueryable method in my filter, but I keep getting exceptions thrown on the last line shown: ConstantExpression ce = Expression.Constant

I have a class called 'Article' in a project called 'MyProject.Data', which acts as the data layer for my web application. I have a separate project called 'MyProject.Admin', which is a web-based admin system for viewing/editing the data, and was build using ASP.NET Dynamic Data. Basically I want to extend the Article class, using a partial class, so that I can augment one of its properties with a "UIHint" extender, which will allow me to replace the normal multi-line textbox with an FCKEdit control. My partial class and extender would look like this: [MetadataType(typeof(ProjectMetaData))]
