I want to know how can I get the route values in Razor Pages (Page.cshtml).
Ex.
https://localhost:44320/AdminPanel/Admins
if I was using MVC i would get these datas as
var controller = ViewContext.RouteData.Values["Controller"]; //AdminPanel
var action = ViewContext.RouteData.Values["Action"]; //Admins
How can i get these values in Razor Pages?
For anyone trying to get it you can get it by:
var fullRoute = ViewContext.RouteData.Values["Page"]; // AdminPanel/Admin
Assuming you have a page named AdminPanel.cshtml in your Pages folder, add a parameter after #page on the first line, like this:
#page "{action}"
Then in the code behind (AdminPanel.cshtml.cs), add a prop and a parameter to your OnGet method like so:
private string _action;
public void OnGet(string action) {
_action = action; //now do whatever you want with it
}
You can add a getter if you want to access it in your model back on the cshtml page.
Note: doing the above will make that page require an action be specified. Alternatively, you can also make it optional by adding a question mark (#page "{action?}") and setting a default value in your OnGet (OnGet(string action="")).

Somehow I find this hard to describe, but here I go:
I have a div in my SelectClasses Razor view page with an id="id152".
In order for me to show that div on the page at reload, I have to add the suffix #id152 to my page url.
<div id="id152">blabla</div>
...
..
Section 7
Now my question: Is there a way to add/pass this suffix to a 'RedirectToAction()'?
public ActionResult Index()
{
//All we want to do is redirect to the class selection page and add a suffix
return RedirectToAction("SelectClasses", "Registration", new { id = 99 })); //add suffix here somewhere
}
So when my SelectClasses view is shown, the url looks something like this:
'[url]/SelectClasses/99#id152'
The RedirectToActionResult (among the rest of RedirectTo* results) is meant to be used for generation of URLs based on registered routing data.
In your case, you wish to concatenate a hash parameter value (#id152) that is not being sent to the server and only used by the browser. That's why said methods don't bother dealing with it.
I suggest you do this instead:
var redirUrl = Url.Action("SelectClasses", "Registration", new { id = 99 });
redirUrl = String.Concat(redirUrl, "#id152");
return Redirect(redirUrl);
I'm trying to set up a function in Polymer 1.0 which will allow a JSON response to tell my application which {{BindingVariable}} in which to insert the response. Unfortunately, the syntax for referencing these binding variables seems to be similar to this:this.BindingVariable, which doesn't allow for dynamic variable names.
What I really need is a way to reference these dynamically like how we can reference anything else in the DOM/PolyDOM. For example: document.querySelector('#'+elementID).
Is there any way to reference binding annotations dynamically? I've searched through the entire Polymer DOM and can't find them listed anywhere even though I know they're in the page.
example
app._onResponseRetrieved = function(e) {
for (var key in e.detail.response) {
// none of these work, but they demonstrate what I'm trying to accomplish
// this.key = e.detail.response[key];
// this.querySelector(key) = e.detail.response[key];
// window[key] = e.detail.response[key];
// document[key] = e.detail.response[key];
// Polymer.dom(key) = e.detail.response[key];
}
JSON Sent to _onResponseRetrieved
{"contactFormOutput":"Success!"}
Binding Annotation in index.html
<div>{{contactFormOutput}}</div>
this[key] = e.detail.response[key];
Javascript allows [] on any object for dynamic property referencing
I want to route from one page to another page.
Candidatesvas- controller
Here I have code,
[Authorize, HttpPost,HandleErrorWithAjaxFilter]
public ActionResult Details(FormCollection collection)
{
Order order = _repository.GetOrder(LoggedInOrder.Id);
order.CreateDate = DateTime.Now;
order.Amount = 360;
order.Validity = 60;
_repository.Save();
}
when I click Index page,"any link", it saves in db and go to next details page.
Index.aspx:
<%:Html.actionlink("Details","Details","Candidatesvas")%>
like that...
Global.ascx:
routes.MapRouteLowercase(
"SaveVas",
"details/candidatesvas",
new { controller = "Candidatesvas", action = "Details" }
);
But when i click link, it shows "resource cannot be found". i changed many way. please help me. i can't find out the issue?
Your controller action is decorated with the [HttPost] attribute which means that this action is only accessible with the POST verb. Then you have shown some link on your page:
<%:Html.ActionLink("Details","Details","Candidatesvas")%>
But as you know a link sends GET request. If you want to be able to invoke this action you should either remove the [HttpPost] attribute from it or use an HTML <form> instead of a link.
try this
<%:Html.actionlink("Details","Details","Candidatesvas",null,null)%>
You can't use Html.actionlink for post method.
go for jquery
Or call form submit on click function.
I am using the SSRS 2008r API to create and manage SSRS from a webform application. When creating a folder I see where I can add a folder name as well as specify additional meta data (custom properties) that can be a part of the folder. My question is how do I populate additional fields in the catalog database via the api. When I look at the CreateFolder method the only properties I can add at the insert are folder name, path, and custom properties:
rs.CreateFolder(folderName, "/", props); // foldername is a string passed in from the form
However I would also like to set at this time the description, and hidden value.
I'd appreciate any suggestions on how this is accomplished. Every example I have seen within MSDN only shows setting the folder name, path, and custom properties.
thanks in advance
Set the item properties (Description and Hidden) by initializing a Property class for each. Never done it before, but I'm guessing it would look something like this (assuming C#):
...
// description property
Property description = new Property();
description.Name = "Description";
description.Value = "Your description here.";
// hidden property
Property hidden = new Property();
hidden.Name = "Hidden";
hidden.Value = "True"; // not sure on value here, may be True/False, Yes/No
// build properties array
props[0] = description;
props[1] = hidden;
// create folder
rs.CreateFolder(folderName, "/", props); // foldername is a string passed in from the form
I have a simple function that I want to call in the code behind file name Move
and I was trying to see how this can be done and Im not using asp image button because not trying to use asp server side controls since they tend not to work well with ASP.net MVC..the way it is set up now it will look for a javascript function named Move but I want it to call a function named move in code behind of the same view
<img alt='move' id="Move" src="/Content/img/hPrevious.png" onclick="Move()"/>
protected void Move(){
}
//based on Search criteria update a new table
protected void Search(object sender EventArgs e)
{
for (int i = 0; i < data.Count; i++){
HtmlTableRow row = new HtmlTableRow();
HtmlTableCell CheckCell = new HtmlTableCell();
HtmlTableCell firstCell = new HtmlTableCell();
HtmlTableCell SecondCell = new HtmlTableCell();
CheckBox Check = new CheckBox();
Check.ID = data[i].ID;
CheckCell.Controls.Add(Check);
lbl1.Text = data[i].Date;
lbl2.Text = data[i].Name;
row.Cells.Add(CheckCell);
row.Cells.Add(firstCell);
row.Cells.Add(SecondCell);
Table.Rows.Add(row);
}
}
Scott Guthrie has a very good example on how to do this using routing rules.
This would give you the ability to have the user navigate to a URL in the format /Search/[Query]/[PageNumber] like http://site/Search/Hippopotamus/3 and it would show page 3 of the search results for hippopotamus.
Then in your view just make the next button point to "http://site/Search/Hippopotamus/4", no javascript required.
Of course if you wanted to use javascript you could do something like this:
function Move() {
var href = 'http://blah/Search/Hippopotamus/2';
var slashPos = href.lastIndexOf('/');
var page = parseInt(href.substring(slashPos + 1, href.length));
href = href.substring(0, slashPos + 1);
window.location = href + (++page);
}
But that is much more convoluted than just incrementing the page number parameter in the controller and setting the URL of the next button.
You cannot do postbacks or call anything in a view from JavaScript in an ASP.NET MVC application. Anything you want to call from JavaScript must be an action on a controller. It's hard to say more without having more details about what you're trying to do, but if you want to call some method "Move" in your web application from JavaScript, then "Move" must be an action on a controller.
Based on comments, I'm going to update this answer with a more complete description of how you might implement what I understand as the problem described in the question. However, there's quite a bit of information missing from the question so I'm speculating here. Hopefully, the general idea will get through, even if some of the details do not match TStamper's exact code.
Let's start with a Controller action:
public ActionResult ShowMyPage();
{
return View();
}
Now I know that I want to re-display this page, and do so using an argument passed from a JavaScript function in the page. Since I'll be displaying the same page again, I'll just alter the action to take an argument. String arguments are nullable, so I can continue to do the initial display of the page as I always have, without having to worry about specifying some kind of default value for the argument. Here's the new version:
public ActionResult ShowMyPage(string searchQuery);
{
ViewData["SearchQuery"] = searchQuery;
return View();
}
Now I need to call this page again in JavaScript. So I use the same URL I used to display the page initially, but I append a query string parameter with the table name:
http://example.com/MyControllerName/ShowMyPage?searchQuery=tableName
Finally, in my aspx I can call a code behind function, passing the searchQuery from the view data. Once again, I have strong reservations about using code behind in an MVC application, but this will work.
How to call a code-behind function in aspx:
<% Search(ViewData["searchQuery"]); %>
I've changed the arguments. Since you're not handling an event (with a few exceptions, such as Page_Load, there aren't any in MVC), the Search function doesn't need the signature of an event handler. But I did add the "tablename" argument so that you can pass that from the aspx.
Once more, I'll express my reservations about doing this in code behind. It strikes me that you are trying to use standard ASP.NET techniques inside of the MVC framework, when MVC works differently. I'd strongly suggest going through the MVC tutorials to see examples of more standard ways of doing this sort of thing.
