Copy the XPO\XpoHelper.cs(vb) file to your project. To add this functionality to an existing ASP.NET MVC project, do the following:ġ. The usage is demonstrated in the Controllers\OrdersController.cs(vb) file. It provides the implementation of typed method delegates required to calling to a grid view model's GridViewModel.ProcessCustomBinding method. The XPO\XpoBindingHandlers.cs(vb) file contains a universal class that can be used in real projects without modifications. In real projects, it should be replaced with a custom implementation integrated with the application architecture and business requirements.Ĥ. This implementation is intended for demonstration purposes only. In the example, the XPDictionary instance is prepared in the XPO\DatabaseSchemaHelper.cs(vb) file. XPDictionary provides metadata information used to map persistent objects to database tables. The GetNewSession and GetNewUnitOfWork methods implemented in the extended XpoHelper class accept an XPDictionary instance as a last parameter. The XpoDefault.GetConnectionPoolString method is used to prepare such connection string.ģ. XPO automatically creates DataStorePool when the connection string contains the special parameter. To handle the concurrent access to a data store, this example uses the DataStorePool component. Refer to the XPO\XpoHelper.cs(vb) file for implementation details.Ģ. To address this requirement, it is necessary to create a separate Data Access Layer for each user, instead of sharing a single ThreadSafeDataLayer instance between all users as it recommended to do in regular scenarios. In this scenario, the persistent classes schema can be changed at run time.

This example extends a standard approach of connecting an ASP.NET application to an XPO data store described in this article: How to use XPO in an ASP.NET (Web) application. Refer to our online documentation to understand concepts used in this example.ġ. XPO provides components that can be used to load objects without knowing their types at compile time ( XPCollection) or building complex queries with grouping, filtering, sorting and data aggregation ( XPView). Our GridView component for ASP.NET MVC platform has an API that allows you to populate a grid with data manually taking into account the current grid state (filtering, sorting, grouping) - Custom Data Binding.Ĥ.
Refer to this Knowledge Base article to learn more about this functionality: How to create persistent metadata on the fly and load data from an arbitrary table.ģ. XPO supports dynamic mapping to the database tables without declaring any classes. Refer to the tutorials in our online documentation to get started with XPO: Getting Started.Ģ. eXpress Persistent Objects (aka XPO) are used as a data access layer. This example is based on the following technologies:ġ. This approach can be used to support adding/removing database columns without modifying the application code, to implement a generic View consuming data from an arbitrary table (or even database) selected by the user, or to implement a SaaS application. The approach demonstrated in this example can be used when you need to take advantage of the partial data loading feature, but cannot use statically declared business models mapped to the database. How to bind editors to XPO objects in an ASP.NET MVC application How to use XPO in an ASP.NET (Web) application Refer to the following articles for XPO best practices: This example demonstrates an edge-case scenario and uses XPO in an uncommon way. How to bind an ASP.NET MVC GridView extension to a table with an unknown schema using Custom Data Binding and XPO XpoBindingHandlers.cs (VB: XpoBindingHandlers.vb).DatabaseSchemaHelper.cs (VB: DatabaseSchemaHelper.vb).OrdersController.cs (VB: OrdersController.vb).But how to pass in these templates using a simple C# parameter. Required parameters: a header and footer template, item template, edit item template. The idea was simple: an extension method to the HtmlHelper class would be enough. Why not create a simple GridView extension method which generates a nice looking, plain-HTML grid with all required features like paging, editing, deleting, alternating rows. I advised him to look for a nice foreach implementation or using ExtJS, Dojo or similar.

Code based ASP.NET MVC GridView JEdit on GitHubĮarlier this week a colleague of mine asked me if there was such thing as a DataGrid or GridView or something like that in the ASP.NET MVC framework.
