Web Api Request Content is empty in action filter

by

The request body is a non-rewindable stream; it can be read only once. The formatter has already read the stream and populated the model. We’re not able to read the stream again in the action filter. You could try: public class LogAttribute : ActionFilterAttribute { public override void OnActionExecuting(HttpActionContext actionContext) { var myModel = actionContext.ActionArguments[“myModel”]; … Read more

Dependency injection and ASP.Net Membership Providers

If you are configuring the custom membership providers via the <membership> element in the Web.config file, then I can see the issues you will have with dependency injection.

401 response code for json requests with ASP.NET MVC

by

In classic ASP.NET you get a 401 http response code when calling a WebMethod with Ajax. I hope they’ll change it in future versions of ASP.NET MVC. Right now I’m using this hack: protected void Application_EndRequest() { if (Context.Response.StatusCode == 302 && Context.Request.Headers[“X-Requested-With”] == “XMLHttpRequest”) { Context.Response.Clear(); Context.Response.StatusCode = 401; } }

So you should load the data by using ToList and then translate into SelectListItem as: var query = dba.blob.ToList().Select(c => new SelectListItem { Value = c.id.ToString(), Text = c.name_company, Selected = c.id.Equals(3) }); Edit: To make it more … Read more
