I have a strange issue in my blazor app. I don't know why but when I navigate from a specific path of my app to another path then I get a 400 disconnect message in my browser console.
When I navigate back to the entry point the connection becomes established again.
There are these paths right now
/
/Admin/Users
/Admin/Users/{name}
Admin/Users shows me a list of all employees from my SQL-Database.
<table class="table table-bordered">
<thead>
<tr>
<th>Name</th>
<th>E-Mail</th>
<th>Status</th>
<th>Aktion</th>
</tr>
</thead>
<tbody>
#foreach (var mitarbeiter in UserManager.Users)
{
<tr>
<td>#mitarbeiter.FirstName #mitarbeiter.LastName</td>
<td>#mitarbeiter.Email</td>
<td></td>
<td>
<a href="/Admin/Users/#mitarbeiter.UserName" class="btn btn-primary">
<i class="fa fa-edit"></i>
</a>
</td>
</tr>
}
</tbody>
</table>
As you can see, each employee has a a-Tag to /Admin/Users/{name}. When I click on it, everything works as expected. When I use the navigation now to go back to /Admin/Users then the connection will be terminated. It becomes established again when I go to / or to /Admin/Users manually again.
The navigation is defined as:
<AuthorizeView Roles="Administratoren">
<Authorized>
<div class="sb-sidenav-menu-heading">System</div>
<nav class="sb-sidenav-menu-nested nav">
<NavLink href="/Admin/Users" class="nav-link">Benutzer</NavLink>
</nav>
</Authorized>
</AuthorizeView>
The page /Admin/Users/{name} just displays some razor components to edit the employee. All sites uses the same default layout which contains the blazor.server.js
<script src="/_framework/blazor.server.js"></script>
Does anybody know, how I can fix this issue or what is causing it?
Thanks in advance!
To fix this issue, I added the following code to my _Host.cshtml
<base href="~/" />

I have a bit of a dilemma. I have a table of 3 columns. Column 1 is a button to make that row active. The 2nd column is the name of the person. And the 3rd column is a button to view the person's details.
Using Selenium C#, I can search for a specific person in the table and click the button to View, using the code below:
currentDriver.FindElement(By.XPath("(.//*[normalize-space(text()) and normalize-space(.)='Name of person'])")).Click();
How do I select the button before the name of the person?
EDIT: Added HTML -
<table class="table table-hover>
<thead>...</thead>
<tbody id="listCompany">
<tr>
<td>
<span id="a5" class="badge btnActivateCompany clsActiveCompany15" ><i class="fas fa-times"></i></span>
</td>
<td>Test Director</td>
<td>
<button.>...</button>
</td>
</tr>
</tbody>
The class btnActivateCompany is used several times depending on how many rows exist. And the id changes depending on the rows as well. So I have to search to find the correct record and then select the span before it.
I tried the following to select the object:
currentDriver.FindElement(By.XPath("(.//*[normalize-space(text()) and normalize-space(.)='Test Director'])[1]/preceding::span[1]")).Click();
I get the feeling you've modified the HTML as you've posted. I guess you stripped out some data and typed other content in. You say you want the button before the person, but in your code the button is after the person?
Either way, both are achievable. I made a few quick additions to help visibility. If i'm wrong please correct me as it influences xpaths.
Quick change log: I ran your html through a beautifier, added text to all the columns for visibility, added "border=1" to the table, remove the . from button, added the </table> and duplicated the row so i can check unique objects are found.
This is the result: (useful if anyone else wants to chip in an identifier)
<html>
<body>
<table class="table table-hover" border=1>
<thead>...</thead>
<tbody id="listCompany">
<tr>
<td>
<span id="a5" class="badge btnActivateCompany clsActiveCompany15" >
<i class="fas fa-times"> Column 1</i>
</span>
</td>
<td>Test Director</td>
<td>
<button> Button in col 3
</button>
</td>
</tr>
<tr>
<td>
<span id="a5" class="badge btnActivateCompany clsActiveCompany15" >
<i class="fas fa-times"> Column 1</i>
</span>
</td>
<td>Second Row!</td>
<td>
<button> Button in col 3
</button>
</td>
</tr>
</tbody>
</table>
</body>
</html>
That renders like this:
Based on fact you say you can get the text in the middle column...
If you want the button in column 3, you can try xpath:
//td[text()='Test Director']/parent::*/td/button
If you want the span in column 1, you can try:
//td[text()='Test Director']/parent::*/td/span[contains(#class,'btnActivateCompany')]
In both of these instances this selects a unique hit in the source.
However, please note, this is dependent on the html provided. If there are other elements/attributes in the table the xpath might need more work. I'm happy to help more but you'll need to share more content.
Hi I have a question is that possible to have function to display my table after the button was pressed, because now it's always on? I've tried with some IF functions but they weren't working.
My code:
#using (Html.BeginForm("Search", "Home", FormMethod.Post))
{
<br />
<span style="font-weight: bold">Tytuł filmu:</span> #Html.TextBox("VideoName")
<input type="submit" value="Szukaj" class="btn-primary" />
<br />
<br />
<table cellpadding="0" cellspacing="0">
<tr>
<th>
#Html.DisplayNameFor(model => model.ImageUrl)
</th>
<th>
#Html.DisplayNameFor(model => model.VideoName)
</th>
</tr>
#foreach (var item in Model)
{
<tr>
<td>
#Html.DisplayFor(modelItem => item.ImageUrl)
</td>
<td>
#Html.DisplayFor(modelItem => item.VideoName)
</td>
</tr>
}
</table>
}
If you put your markup inside a conditional block as follows:
#if (true)
{
#* PUT MARKUP HERE *#
}
Then the markup will only appear when the if condition is true.
Alternatively, you can use client-side code to simply hide the markup. I don't know which is best, because you haven't provided any details about what you are doing.
Instead of saying THE button, perhaps you should've talked about what kind of button you have and what is it supposed to do. If it works server side, use my first suggestion. If it needs to work client side, use my second suggestion.
You can do that in number of ways,
Javascript:
document.getElementById('mytable').style.display = 'block';
Give your table an ID and set its display to none; initially, then using javascript on the button click switch the table display to block;
function buttonClick(){
document.getElementById('myTable').style.display = 'block';
}
<table id='myTable' style='display:none;'>...</table>
<input type="submit" value="Szukaj" class="btn-primary" onclick='buttonClick()' />
Notes:
- It can be much easier if you are using jquery
- You can use event listener for the button click
Server side code:
On your action method set a TempData or ViewBag variable and then in the html check if this value exist, if true show the table
I am sure there are many other ways to do that but most of them will be around both ideas I listed.
You can have a button that toggles the visibility of the table, call the below function on the button onclick event to show or hide the table.
function toggleTable() {
var lTable = document.getElementById("YourTableId");
lTable.style.display = (lTable.style.display == "table") ? "none" : "table";
}
You have several good answers but it depends on exactly what you are trying to accomplish. I've used a variety of what has been provided. You mention showing table on button click. Do you also need to hide table if said button is clicked again? If so, client side jQuery and .toggle() could help.
$(document).ready(function(){
$("button").click(function(){
$("#myTable").toggle();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<button>Toggle</button>
<table id="myTable" style="border: 1px solid black; display: none">
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
<tr>
<td>Data 1</td>
<td>Data 2</td>
</tr>
</table>
I have an ASP.NET View using server-side #foreaches, now replaced with AngularJS.
Now I use ng-repeat="record in records", and I don't use anymore the #foreach.
The actual code that worked with #record.Id now does not work with {{record.id}}:
<td class="text-nowrap">
<a asp-controller="Records" asp-action="Edit" asp-route-id="{{record.id}}">Edit</a>
<a asp-controller="Records" asp-action="Details" asp-route-id="{{record.id}}">View</a>
<a asp-controller="Records" asp-action="Delete" asp-route-id="{{record.id}}">Delete</a>
</td>
obviously, because the #record.Id was on the server side...
Now, the solution I see it to set something like
However if the controller's route will change it could lead to nowhere... Is there a way to workaround that?
PS.
Some more code for better understanding:
<div ng-app="tablesApp" ng-controller="tablesController as tc">
<table>
<thead>
<tr>
<th>#Html.DisplayNameFor(model => model.Name)</th>
<th>#Html.DisplayNameFor(model => model.Description)</th>
<th></th>
</tr>
</thead>
<tbody>
<tr ng-repeat="record in records">
<td>{{record.name}}</td>
<td>{{record.description}}</td>
<td>
<a asp-controller="Records" asp-action="Edit" asp-route-id="{{record.id}}">Edit</a>
<a asp-controller="Records" asp-action="Details" asp-route-id="{{record.id}}">View</a>
<a asp-controller="Records" asp-action="Delete" asp-route-id="{{record.id}}">Delete</a>
</td>
</tr>
</tbody>
</table>
</div>
JS Controller:
$http.get("/api/Records")
.then(function (response) {
tc.records = response.data;
}));
Actually a little bit better option that the hardcoded route is to use
<a href="#Url.Action(action: "Edit", controller: "Records")/{{record.id}}" ></a>
However this one is supposed to have the {ActionRoute}/{id} fixed structure...
In case you use foreach in razor view (obviously you do) then you can't use angular syntax {{record.id}} you have to use #record.id
But if you get records, as an array/list whatever, in AngularJs then you have to change your html and use ng-repeat
-- Edit
Sorry just see your code again, you used asp-action and asp-controller etc
They are TAG HELPERS from core version, in other words they will get rendered on the server side and what you will get in the browser actually is anchor link like
<a href="/Records/Edit/{{record.id}}" >Edit</a>
AngularJs as you know is client side so it won't render. Either use #Url.Action as you already did or you could remove asp-route-id and add the id later using custom directive.
There is a mvc application, in which I am trying to modify in pre-compiled CSHTML page(Index.cshtml)
#using System.Web.Mvc.Html
#model Services.Admin.ViewModels.IndexViewModel
#{
Layout = "~/Views/Admin/_Layout.cshtml";
ViewBag.Title = Resources.AdminResources.Index_Title;
}
<div class="container">
<div class="masonry">
<div class="item col-lg-4 col-md-4 col-sm-4">
<h3>Event Clinics</h3>
<table class="table table-striped table-bordered table-hover">
<tbody>
<tr>
<td class="max-width">
#Html.ActionLink("Premier Instructors", "Index", "PremierInstructor")
</td>
<td></td>
</tr>
<tr>
<td class="max-width">
#Html.ActionLink("Reports", "Index", "Reports")
</td>
<td></td>
</tr>
<tr>
<td class="max-width">
#Html.ActionLink("Users", "Index", "Users")
</td>
<td></td>
</tr>
</tbody>
</table>
</div>
</div>
Here is also respective Index.generated.cs, in which all code is written with help of "WriteLiteral".
When I am trying to add/modify in .cshtml form, it's impact not showing on UI.
I have also find out on various sites and found that these cshtml is already compiled using "RazorGenerator" tools.
Now My problem is this, when I am going to make any changes in this type of cshtml file, it is not reflected on screen.
In case of RazorGenerator based pre-compiled .cshtml forms as there is need to modify it's html then follow below steps.
Right Click on .chstml file (ex. index.cshtml).
Click on "Properties".
Under "Advanced" section remove "RazorGenerator" from "Custom Tool" option.
DO CHANGES IN CSHTML FILE.
Again follow above 1,2 steps.
Under "Advanced" section add "RazorGenerator" in "Custom Tool" option.
Save form and run it.
Now you will be seeing all the changes in UI.
I am using ASP .Net MVC 4.0 and VS10. I am a newbie in web application.
I have designed a page with html razor view. Here is some code of Index.cshtml:
#{
ViewBag.Title = "BAP Automation";
}
#section featured {
<section class="featured">
<div class="content-wrapper">
<hgroup class="title">
<h1>#ViewBag.Title.</h1>
<h2>#ViewBag.Message</h2>
</hgroup>
<form action="Index">
<table> **//EDITED BELLOW**
<tr><form action="" method="post">
<td>Upload Excel File: </td>
<td><input type="text" name="NAMEtxtFileName"/></td>
<td><input type="button" value="Upload" id="IDbtnUpload" name="NAMEbtnUpload"/></td>
</form>
</tr>
<tr>
<td>Company Name: </td>
<td><input type="text" /></td>
<td></td>
</tr>
<tr>
<td></td>
<td align="right"><input type="submit" value="Process" /></td>
<td></td>
</tr>
</table>
</form>
</div>
</section>
}
I am trying to upload an excel file in NAMEbtnUpload's click event. clicking on this button we will be in this page, just a file upload dialog will open and selecting the file, the file location will be shown in the NAMEtxtFileName textbox.
EDIT 1:
I have written some code from the suggested code:
[HttpPost]
public ActionResult Index(HttpPostedFileBase NAMEbtnUpload)
{
if (NAMEbtnUpload.ContentLength > 0)
{
var fileName = Path.GetFileName(NAMEbtnUpload.FileName);
var path = Path.Combine(Server.MapPath("~/App_Data/Given Excel's"), fileName);
NAMEbtnUpload.SaveAs(path);
}
return RedirectToAction("Index");
}
but this shows following error:
Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested URL: /
Try adding the "EncType" attribute to your form.
#using (Html.BeginForm("ACTION", "CONTROLLER", FormMethod.Post, new { EncType="multipart/form-data"})){
//FORM MARKUP HERE
}
Phil Haack shows you how to handle file uploads with his blog post Uploading a File (Or Files) With ASP.NET MVC.
There is quite a bit of stuff you are missing so reading that post will get you further than any answer here.
** UPDATE FOR EDIT 1 **
A couple issues
<form action="index" > - this should be <form action="/ControllerName/Index">
You have multiple form tags that are nested. You can have multiple form tags but they can't be nested. In your case your only need one. Most of the time you only need 1.
<input type="button" value="Upload" id="IDbtnUpload" name="NAMEbtnUpload"/> should be
It is more conventional to use #using(Html.BeginForm()) as opposed to manually writing form tags. See below.
#using(Html.BeginForm("Index"))
{
<table>
<tr>
<td>Upload Excel File: </td>
<td><input type="text" name="NAMEtxtFileName"/></td>
<td><input type="file" id="IDbtnUpload" name="NAMEbtnUpload"/></td>
</tr>
<tr>
<td>Company Name: </td>
<td><input type="text" /></td>
<td></td>
</tr>
<tr>
<td></td>
<td align="right"><input type="submit" value="Process" /></td>
<td></td>
</tr>
</table>
}
clicking on [the upload] button we will be in this page, just a file upload dialog will open and selecting the file, the file location will be shown in the NAMEtxtFileName textbox.
That is not possible because a file upload element is not accessible programatically, anymore. "Back in the days" it was, and malicious sites silently uploaded sensitive information by setting the file upload control's value to well known password file locations and so on.
You'll just have to put an <input type="file" /> on your form and handle the upload serverside, as suggested in the link on #Bretts answer.
Set the name of file control in controller class.
for example in above code
public ActionResult Index(HttpPostedFileBase NAMEbtnUpload)
change NAMEbtnUpload to NAMEtxtFileName
this resolve your problem.
