Programmatic Model Binding Using UpdateModel() |
|
ASP.NET MVC offers model binding to capture form field values entered in a view. In many cases model binding to complex types serves the purpose. When the model type to fill from the values is known at development time, you can specify a parameter of that type. However, this is not always the case. That is where programmatic model binding comes handy. Programmatic model binding allows you to perform model binding at runtime based on some condition or processing logic. |

Wouldn't it be nice if server notifies the client of new data rather than client checking with the server periodically? That is what Server Sent Events (SSE) allow you to do. |

AngularJS Directive That Invokes ASP.NET MVC Action |

Recently one of the readers asked whether an AngularJS directive can invoke ASP.NET MVC actions. This article shows how a simple AngularJS directive can be created that invokes an ASP.NET MVC action using Ajax. Usually an AngularJS directive is used to perform some UI centric operation. However, nothing prevents an AngularJS directive from invoking some server side code (say an action method) to get some job done.
