The ASP.NET WebForms trace output has a section for Application State. Is it possible to see the same using Glimpse?
In my home controller's Index() method, I tried adding some test values, but I don't see the output in any of the Glimpse tabs.
ControllerContext.HttpContext.Application.Add("TEST1", "VALUE1");
ControllerContext.HttpContext.Cache.Insert("TEST2", "VALUE2");
I didn't see anything in the documentation either.
I don't think that there is an out-of-the-box support for this, but it would be trivial to write a plugin that will show this information.
For example to show everything that's stored in the ApplicationState you could write the following plugin:
[Glimpse.Core.Extensibility.GlimpsePluginAttribute]
public class ApplicationStateGlimpsePlugin : IGlimpsePlugin
{
public object GetData(HttpContextBase context)
{
var data = new List<object[]> { new[] { "Key", "Value" } };
foreach (string key in context.Application.Keys)
{
data.Add(new object[] { key, context.Application[key] });
}
return data;
}
public void SetupInit()
{
}
public string Name
{
get { return "ApplicationState"; }
}
}
and then you get the desired result:
and to list everything that's stored into the cache:
[Glimpse.Core.Extensibility.GlimpsePluginAttribute]
public class ApplicationCacheGlimpsePlugin : IGlimpsePlugin
{
public object GetData(HttpContextBase context)
{
var data = new List<object[]> { new[] { "Key", "Value" } };
foreach (DictionaryEntry item in context.Cache)
{
data.Add(new object[] { item.Key, item.Value });
}
return data;
}
public void SetupInit()
{
}
public string Name
{
get { return "ApplicationCache"; }
}
}

I'm trying to save my session in ASP.NET Core, but it is not getting saved.
I have looked at other answers, suggesting to change CookiePolicyOptions and nothing has worked so far. I have another project with the exact same code (presumably), and it works there but not in this project.
In my controller I have:
[HttpPost]
public IActionResult AddToPlan(int mealId)
{
PlanCart planCart = GetPlanCart();
planCart.AddItem(mealId);
SavePlanCart(planCart);
// ALWAYS 1
var y = planCart.returnList();
foreach (var x in y)
{
var z = x; // For debug purposes
}
return RedirectToAction("Index");
}
private PlanCart GetPlanCart()
{
PlanCart planCart = HttpContext.Session.GetJson<PlanCart>("PlanCart") ?? new PlanCart();
return planCart;
}
private void SavePlanCart(PlanCart planCart)
{
HttpContext.Session.SetJson("PlanCart", planCart);
}
I have a class with extension methods:
public static class SessionsExtensions
{
public static void SetJson(this ISession session, string key, object value)
{
session.SetString(key, JsonConvert.SerializeObject(value));
}
public static T GetJson<T>(this ISession session, string key)
{
var sessionData = session.GetString(key);
return sessionData == null
? default(T) : JsonConvert.DeserializeObject<T>(sessionData);
}
}
Startup class:
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseAuthentication();
app.UseSession();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
app.UseCookiePolicy();
}
services.Configure<CookiePolicyOptions>(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.None;
});
services.AddSession();
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
services.AddMemoryCache();
I have checked my session. The session DOES exist but every time the count of the PlanCartList is 1 and previous items are lost.
If anybody could help me it would be very much appreciated because I'm losing my mind here!
I am using the Grid of Kendo (Angular 2) for Add/Edit/Delete a Row in the grid:
http://www.telerik.com/kendo-angular-ui/components/grid/editing/
In the original Code, the data is obtained from a rest service like this:
private fetch(action: string = "", data?: Product): Observable<Product[]> {
return this.jsonp
.get(`http://demos.telerik.com/kendo-ui/service/Products/${action}? callback=JSONP_CALLBACK${this.serializeModels(data)}`)
.map(response => response.json());
}
But, I want to work with a array for add/edit/delete rows in memory. Next, I want to do click in the button submit and send the data (with all my changes) to the server.
My solution for this is like this:
https://gist.github.com/joedayz/9e318a47d06a7a8c2170017eb133a87e
Overview:
I declare an array:
private view: Array = [{ProductID: 1, ProductName: "pelotas", Discontinued: undefined, UnitsInStock: 80}];
and override the fetch method like this:
private fetch(action: string = "", data?: Product): Observable<Product[]> {
/*return this.jsonp
.get(`http://demos.telerik.com/kendo-ui/service/Products/${action}?callback=JSONP_CALLBACK${this.serializeModels(data)}`)
.map(response => response.json());*/
debugger;
if(action=="create"){
var product : Product = new Product(-1, data.ProductName, data.Discontinued, data.UnitsInStock);
this.view.push(product);
}else if(action=="update"){
var indice = this.view.indexOf(data);
if(indice>=0)
this.view[indice] = (JSON.parse(JSON.stringify(data)));
}else if(action=="destroy"){
var indice = this.view.indexOf(data);
if(indice>=0)
this.view.splice(indice, 1);
}
return Observable.of(this.view);
}
My Question is: Exists some way of communicate the create/update/delete of items in my array of a simple or reactive form to my grid?
As you are using in-memory array you do not need to use Observables. The Grid component is already bound to the array, thus it is just necessary to manipulate the data. For example:
export class AppComponent {
public dataItem: Product;
#ViewChild(GridEditFormComponent) protected editFormComponent: GridEditFormComponent;
private view: Array<Product> = [{ ProductID: 1, ProductName: "pelotas", Discontinued: undefined, UnitsInStock: 80 }];
public onEdit(dataItem: any): void {
this.dataItem = Object.assign({}, dataItem);
}
public onCancel(): void {
this.dataItem = undefined;
}
public addProduct(): void {
this.editFormComponent.addProduct();
}
public onSave(product: Product): void {
if (product.ProductID === undefined) {
this.createProduct(product);
} else {
this.saveProducts(product);
}
}
public onDelete(e: Product): void {
this.deleteProduct(e);
}
public saveProducts(data: Product): void {
var index = this.view.findIndex(x => x.ProductID === data.ProductID);
if (index !== -1) {
this.view = [
...this.view.slice(0, index),
data,
...this.view.slice(index + 1)
];
}
}
public createProduct(data: Product): void {
this.view = [...this.view, data];
}
public deleteProduct(data: Product): void {
this.view = this.view.filter(x => x.ProductID !== data.ProductID);
}
}
Given the following simple OData 4 controller (please see below), how do I $select just the cities?
http://localhost//api/Customers?$select=Location
Gives me:
{
"#odata.context":"http://localhost/api/$metadata#Customers(Location)","value":[
{
"Location":{
"Country":"Ireland","City":"Sligo"
}
},{
"Location":{
"Country":"Finland","City":"Helsinki"
}
}
]
}
But I don't know how to drill down one deeper so that I just get the cities. Is this even possible?
public class CustomersController : ODataController
{
private List<Customer> customers = new List<Customer>()
{
new Customer
{
CustomerId = 1,
Location = new Address
{
City = "Sligo",
Country = "Ireland"
}
},
new Customer
{
CustomerId = 2,
Location = new Address
{
City = "Helsinki",
Country = "Finland"
}
}
};
[EnableQuery]
public List<Customer> Get()
{
return customers;
}
}
The grammar for $select does not allow a path expression like Location/City. Your best bet is to define an OData function bound to the Customers entity set. E.g.,
[HttpGet]
public IEnumerable<string> GetCities()
{
return customers.Select(c => c.Location.City);
}
And invoke it as follows:
GET http://localhost/api/Customers/ServiceNamespace.GetCities
I wish to store an action link in the model.
Something like
public MvcHtmlString ActionLink_New
{
get { return Html.ActionLink("new", "Edit", "News", new { Area = "Admin" }, null); }
}
It appears the model needs a webviewpage context.
Failing that, I thought I would store just the route values.
public RouteValueDictionary[] RouteValue_New
{
get { return new RouteValueDictionary[] { Area = "Admin" }; }
}
//View
#Html.ActionLink("new", "Edit", "News", Model.RouteValue_New, null)
The Area in the property is red. Is either or both scenario achievable. What do i need to add to get this to work, thanks.
try this
public object RouteValue_New
{
get {
return new { Area = "Admin" };
}
}
I am interested in changing the structure folder. I have read many articles, but I have not found the solution.
I want to do so to distribute the files and folders on thematic folders. I have created a base class BaseViewEngine from RazorViewEngine
public class BaseViewEngine : RazorViewEngine
{
public BaseViewEngine()
{
MasterLocationFormats = new[]
{
"~/Themes/My/master.cshtml"
};
ViewLocationFormats = new[]
{
"~/Modules/{1}/{0}.cshtml"
};
PartialViewLocationFormats = new[]
{
"~/Blocks/{0}.cshtml"
};
}
}
But it is not working.
Update
Control is primitive. Only for test
public class HomeController : Controller
{
public ActionResult Index()
{
var test = new Test { Text = "Hello" };
return View(test);
}
}
And View
#model DemoModules.Test
<h2>Index</h2>
But when I run project. I Get error
CS0103: The name of the 'model' does
not exist in the current context
About structure folder, see the source of subject matter
You don't really have to implement a new engine to change the paths, you can just register them as you want:
private static void RegisterViewEngines(ICollection<IViewEngine> engines)
{
engines.Clear();
engines.Add(new RazorViewEngine
{
MasterLocationFormats = new[] { "~/Themes/My/master.cshtml" },
ViewLocationFormats = new[] { "~/Modules/{1}/{0}.cshtml" },
PartialViewLocationFormats = new[] { "~/Blocks/{0}.cshtml" },
});
}
protected void Application_Start()
{
RegisterViewEngines(ViewEngines.Engines);
}
For reference, the default paths are as follows (not including Areas):
ViewLocationFormats = new [] {
"~/Views/{1}/{0}.cshtml",
"~/Views/{1}/{0}.vbhtml",
"~/Views/Shared/{0}.cshtml",
"~/Views/Shared/{0}.vbhtml"
};
MasterLocationFormats = new [] {
"~/Views/{1}/{0}.cshtml",
"~/Views/{1}/{0}.vbhtml",
"~/Views/Shared/{0}.cshtml",
"~/Views/Shared/{0}.vbhtml"
};
PartialViewLocationFormats = new [] {
"~/Views/{1}/{0}.cshtml",
"~/Views/{1}/{0}.vbhtml",
"~/Views/Shared/{0}.cshtml",
"~/Views/Shared/{0}.vbhtml"
};
Check out this post: http://weblogs.asp.net/imranbaloch/archive/2011/06/27/view-engine-with-dynamic-view-location.aspx
Hope this helps.
Take a look at the web.config file in the default Views folder. There's some stuff in there that is required for Razor views to work - particularly the base class for views and the namespaces that will be used to compile the view.
