in view.cshtml:
#foreach (var choice in question.QuestionChoices)
{
<div class="databox radius-bordered bg-lightgray">
<div class="databox-right bg-blueberry">
<div class="databox-piechart">

how i can fix this issue?
my code is in C# and Asp.net Core.
tnx.


services.AddSingleton<HtmlEncoder>(
HtmlEncoder.Create(allowedRanges: new[] { UnicodeRanges.BasicLatin,
UnicodeRanges.Arabic }));


It looks like you are using a component called "easypiechart" which is not displaying the characters correctly. Is that right?
You must talk to the easypiechart programmers and find a way to fix the problem.
The problem does not seem to be with asp.net core.

Puppeteer.NET: Can't autopopulate field

I am a just starting out with Puppeteer.NET, and i can't get it to autofill a login page.
The HTML for the web site looks like this:

I am trying to get it to fill in the login and password fields, and press the login button.
I am doing it as:
var extra = new PuppeteerExtra();
var stealth = new StealthPlugin();
LaunchOptions options = new LaunchOptions
{
Headless = false,
ExecutablePath = "C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe"
};
Browser browser = extra.Use(stealth).LaunchAsync(options).Result;
string content = null;
using (Page page = browser.NewPageAsync().Result)
{
// do login screen
page.GoToAsync(url);
page.WaitForNavigationAsync();
page.WaitForSelectorAsync("username");
page.FocusAsync("username");
page.Keyboard.TypeAsync(login);
page.WaitForSelectorAsync("password");
page.FocusAsync("password");
page.Keyboard.TypeAsync(password);
page.ClickAsync("submit");
page.WaitForNavigationAsync();
content = page.GetContentAsync().Result;
}
I have tried changing the "username" to "#username" and some other variations, but nothing gets filled in. Ultimately, all I want to to login and then go to a specific page, and have a dump of the resultant HTML.
Also is there a easy way to just a text dump of the resultant HTML?

You can use the selectors #login-form-username and #login-form-password, those are the IDs.

Create a bookmark between 2 different views in MVC

I have two views; Index and Giftworx. In the Index I have icons and when each is clicked it should direct user to a specific point in the GiftWorx page. I've tried the below code but it didnt work. Any help would be appreciated.
Index View:
<div class="col-md-4 w3_agileits_features_grid">
<div class="agileits_w3layouts_features_grid">
<div class="col-xs-4 agileits_w3layouts_features_gridl">
<div class="agile_feature_grid">
#* <i class="fa fa-gift" aria-hidden="true"></i>
</div>*#
<i class="fa fa-gift" aria-hidden="true"></i>
</div>
</div>
<div class="col-xs-8 agileits_w3layouts_features_gridr">
<h4>Who uses GiftWorx</h4>
<p>See who uses GiftWorx and more.</p>
</div>
<div class="clearfix"> </div>
</div>
</div>
GiftWorxView
<div class="why-convertible-box" id="GiftWorxUsers">
<div class="container" id="GiftWorxUsers">
<h1>Who uses GiftWorx<i class="fa fa-question-circle"></i></h1>
</div>
</div>
<div class="hoc container clear" id="GiftWorxUsers">
<div class="row">
<div class="col-md-2" style="padding: 2px;">
<div style="border: lightgrey solid thin; border-radius: 2px">
<img class="img-responsive" style="height:auto;" src="~/Content/myTemplate/Logos/1.jpg" />
</div>
</div>
<div class="col-md-2" style="padding: 2px;">
<div style="border: lightgrey solid thin; border-radius: 2px">
<img class="img-responsive" src="~/Content/myTemplate/Logos/17.jpg" />
</div>
</div>
<div class="col-md-2" style="padding: 2px;">
<div style="border: lightgrey solid thin; border-radius: 2px">
<img class="img-responsive" src="~/Content/myTemplate/Logos/15.jpg" />
</div>
</div>

This is a little bit tricky but should work fine. First I declare the variable with concatenated section of your page:
#{
var strLink = Url.Action("GiftWorxUsers", "GiftWorx") + "#GiftworxArea";
}
Then on your Index View, put this on your a href link:
<div class="agile_feature_grid">
<a href='#strLink'>
<i class="fa fa-gift" aria-hidden="true">
</i>
Link text here
</a>
</div>
Make sure you have an area in your View of Giftworx which has a name in this example: Giftworx by adding this piece of code:
<a name="GiftworxArea"></a>
<div class="col-md-4 w3_agileits_features_grid">
//Other stuffs here
</div>
Now when you click on that link, you will be directed on your page on that exact spot with a section name GiftworxArea.

Model property, collection list is empty upon post to controller, potental issues with MVC with large size string list?

I am trying post a simple list within a model back to the controller. its rendered correctly but on post its always empty. I noticed when I use #Html.Hidden for the id and name are different for instance id becomes TestExceptionDisplay_[0]__Exception and name becomes TestExceptionDisplay[0].Exception. So I use an input type and try to make the way it likes to render but it does not work. I tried partial view, editor templates, nothing seems to work. TestException Display is a very simple list of an object called public List<RunLogEntryTestExceptionDisplay> TestExceptionDisplay { get; set; }
public class RunLogEntryTestExceptionDisplay
{
public string Exception { get; set; }
}
Snippet in the view which uses a for loop to render list, list is rendered fine but on post TestExceptionDisplay is NULL always:
#if (Model.TestExceptionDisplay != null)
{
for (var i = 0; i < Model.TestExceptionDisplay.Count; i++)
{
<tr>
<td>
#Model.TestExceptionDisplay[i].Exception
#*#Html.HiddenFor(m => m.TestExceptionDisplay[i].Exception)*#
<input name="RunLogEntry.TestExceptionDisplay_[#i]__Exception" type="hidden" value="#Model.TestExceptionDisplay[i].Exception" />
</td>
</tr>
}
}
OR this does not even work with editor templates upon post
#if (Model.TestExceptionDisplay != null)
{
#Html.EditorFor(x => x.TestExceptionDisplay)
}
Editor Template in Shared\EditorTemplates with the exact name of RunLogEntryTestExceptionDisplay
#model RunLog.Domain.Entities.RunLogEntryTestExceptionDisplay
<div>
#Html.EditorFor(x => x.Exception)
#Html.HiddenFor(x => x.Exception)
</div>
Rendered HTML looks like below, I did not copy the entire list, PLEASE NOT THAT THE ID AND NAME SEEM TO RENDER IN A DIFFERENT NAMING CONVENTION. IT HAPPENS in both cases, if I use an editor template or a for loop. thanks
<input id="TestExceptionDisplay_9__Exception" name="TestExceptionDisplay[9].Exception" type="hidden" value=""1404 TestException - Parameters:Unable to calculate result, assay is not calibrated for Assay Number (135), Assay Version (5), Track (1), Lane (2), and Reagent Lot Number (26600LI06)"" />

Why are you expecting the list in the model you receive to be populated?
The model on POST is populated only with data from the form - MVC creates a new instance of your model class and populates the fields it can match up.
Because of this, the stock way of making sure your lists are populated is to have a helper method which populates them. You can then call this from either the original Get or the Post method to repopulate the lists.
The only time you'd expect to get a list populated in your model by PMV on postback is when the details to rebuild the list are available in form elements.
It's possible I've missed it in your reams of code but I can't see you doing that anywhere.

You should initialize your list in your first method, then pass to post method.
