is there a way to get a global variable to a view in asp.net/razor to use it to test in and if statement?

right now I am trying to only show a view in my project if my global var privacy is set to true. I am not sure how to call my global variable the same way I do in my controllers but is there a way that I am not thinking of? right now I am trying to call a function that tests this variable and outputs true or false so I can use it in an if statement this feels like a lot more work and I am having problems trying it this way so if there is any way else please let me know.
#if (Elearn.Controllers.AccountController.CheckGdpr())
{
<div class="popup">
<div id="consent-popup" class="hidden">
<p>
we advise our users to accept cookies for the best experience
<input class="btn-glow primary login" value="#_stringLocalizer["Accept Cookies"]" id="accept" />
</p>
</div>
</div>
}
controller function
public bool CheckGdpr()
{
string str = _configuration["privacy:GDPR"];
string checkbol = "True";
if (checkbol == str)
{
return true;
}
else
{
return false;
}
}
If someone knows how to correctly call a controller function too that would help a lot. I am getting an error
Severity Code Description Project File Line Suppression State
Error CS0120 An object reference is required for the non-static field, method, or property 'AccountController.CheckGdpr()' Elearn C:\Users\Isaac\source\repos\elearn2-final_sapce_fixes\Elearn\Elearn\Views\Account\LogOn.cshtml 74 Active

#if (Configuration.GetSection("privacy")["GDPR"] == "True")
this works

System.Web.HttpParseException: 'Unexpected "{" after "#" character

I'm getting this exception while trying to render PartialView. When I change #{Html.RenderPartial("_ChildReplies", parRep.ChildReplies);}
to
#Html.Partial("_ChildReplies", parRep.ChildReplies) still getting same exception.
#model List<Reply>
#using YourPlace.Models
<ul>
#foreach (var parRep in Model)
{
<li>
Author: #parRep.AuthorName
Comment: #parRep.AuthorName
<div>
#{Html.RenderPartial("_ChildReplies", parRep.ChildReplies);}
</div>
</li>
}
</ul>

The code above looks correct... if you are getting this error, it is probably because something is going wrong inside _ChildReplies partial view which you have not shown in your question...
Good explanation here:
RenderPartial() is a void method that writes to the response stream. A void method, in C#, needs a ; and hence must be enclosed by
{ }.
Partial() is a method that returns an MvcHtmlString. In Razor, You can call a property or a method that returns such a string with just a
# prefix to distinguish it from plain HTML you have on the page.
So you need to either use this:
#{ Html.RenderPartial("_ChildReplies", parRep.ChildReplies); }
Or this:
#Html.Partial("_ChildReplies", parRep.ChildReplies);

ASP.NET MVC razor code and javascript errors

I have this code
#if (Model.Name!= null)
{
<div>#Model.Name, <span>#Model.Email</span></div>
}
and I want to highlight the postal code if this condition - IsFlaggedEmail is true:
if (Model.IsFlaggedEmail(out flagComments))
{
<span id="flagged" style="background-color:yellow;font-size:10pt">
}
and I want to display the comments in the title of the span (a tool tip). How can I write this in the cshtml file?
This is what I tried, but I keep getting errors like: "The if block is missing a closing "}" character. Make sure you have a matching "}" character for all the "{" characters within this block, and that none of the "}" characters are being interpreted as markup."
#if (Model.Name!= null)
{
<div>#Model.Name, #{
string flagComments;
if (Model.IsFlaggedEmail(out flagComments))
{
<span id="flagged" style="background-color:yellow;font-size:10pt">
}
} #Model.Email</span></div>
}
#{ string comments;
if (Model.IsFlaggedEmail(out comments)) {
#section Scripts {
$("#flagged").val('title', comments)
}
}}
Also, can I do something like that directly from jQuery?:
#if (Model.Name!= null)
{
<div>#Model.Name, <span id="flagged">#Model.Email</span></div>
}
#{ string flagComments;
if (Model.IsFlaggedEmail(out flagComments)) {
#section Scripts {
$('#flagged').css('background-collor', 'yellow')
$('#flagged').attr('title', #flagComments);​
}
}}

No javascript needed.
You can use something like:
#if (Model.Name != null)
{
string flagComments;
bool isFlagged = Model.IsFlaggedEmail(out flagComments);
<div>
#Model.Name, <span id="#Html.Raw(isFlagged? "flagged": "")">#Model.Email</span>
</div>
And for styling it is better to use CSS. (You have an ID flagged).
Also try to avoid spreading html building across if statements. It is always better to keep tags matching inside one clause.

Dynamically Embed Html Attribute in C# ASP.NET View

I'm trying to dynamically set an attribute(data-status) for a div if a condition is met.
I am currently using the #Html.Raw helper however it's not making its way in to the element.
I have also attempted to use Response.Write() however it just writes everything to the top of the page.
Is there a best way to actually embed this in to the code or maybe create/set a new attribute?
#foreach (var r in Model)
{
<div class="marker"
data-date="#r.date_finished"
data-name="#r.name"
#if (r.complete == "CP")
{
#Html.Raw("data-status='complete'");
}
>
</div>
}

This should do it:
<div class="marker"
data-date="#r.date_finished"
data-name="#r.name"
#{if (r.complete == "CP") { <text>data-status='complete'</text> }}>
Notice the usage of <text> tag. This is a special tag which Razor uses to output content as is.

When I run into this scenario I use a tertiary expression:
<div #(r.complete == "CP" ? "data-status='complete'" : "") >
If your logic is more complex you could also use a static helper method.
<div #r.RenderComplete() >
public static class RExtension{
public static string RenderComplete( this R r){
// logic here
}
}

Why does Razor not like this?

Ive got a mega annoying problem I have a view with:
#{
if(ViewBag.Section == "Home")
{
<div id="headerfrontPage">
}
else
{
<div id="header">
}
}
And I get a compilation error:
The code block is missing a closing "}" character. Make sure you have
a matching "}" character for all the "{" characters within this block,
and that none of the "}" characters are being interpreted as markup.
How do I conditionally write a div? Its for a hack bascially...

You can use the same construct when you wrap your div's inside element like:
#if (ViewBag.Section == "Home")
{
<text><div id="headerfrontPage"></text>
}
else
{
<text><div id="header"></text>
}
Or you use razor syntax #: like
#if (ViewBag.Section == "Home")
{
#:<div id="headerfrontPage">
}
else
{
#:<div id="header">
}
But for your current situation I would prefer Ron Sijm's solution:
#{
var divName = ViewBag.Section == "Home" ? "headerfrontPage" : "header";
}
<div id="#divName">

I suspect it is because your divs are not closed, so razor assumes that the closing brace is actually part of the div content.
You might try outputting the entire div content within your code there, including the closing tag, or output the div tag with a Response.Write, or something similar, so there is no confusing markup.
EDIT: also, maybe enclosing your div tag in a
<text></text>
might be worth a try.

You could try this:
#{
string divName;
if(ViewBag.Section == "Home")
{
divName = "headerfrontPage";
}
else
{
divName = "header";
}
}
<div id="#divName">
I'm not sure if that will help, it a long shot. But at least imo that looks better...

Try this:
#if (ViewBag.Section == "Home")
{
<text> <div id="headerfrontPage"> </text>
}
else
{
<text> <div id="header"> </text>
}

The simplest way to write this would be:
<div id="#(ViewBag.Section == "Home" ? "headerFrontPage" : "header")">
Or, if you prefer, you can use a local variable:
#{ var headerID = ViewBag.Section == "Home" ? "headerFrontPage" : "header"; }
<div id="#headerID">
Regarding the more general case of unclosed tags in Razor code blocks, you can explicitly mark the opening tag as content:
#if (ViewBag.Section == "Home")
{
#:<div id="headerFrontPage">
}
else
{
#:<div id="header">
}
