I am using umbraco 7 ASP.NET C# MVC 4.
Im trying to use the new umbraco, so far its been ok, but i need to get a property of one of my pages i set up.
#inherits Umbraco.Web.Mvc.UmbracoTemplatePage
#{
var homePage = CurrentPage.AncestorsOrSelf(1).First();
var menuItems = homePage.Children.Where("isMenu == true");
}
<!-- Nav -->
<div class="row">
<div class="col-md-12 top-menu-container">
<ul>
#* If the Url of the current page is "/" then we want to add the class "current_page_item" *#
#* Otherwise, we set the class to null, that way it will not even be added to the <li> element *#
<li>
<div onclick="location.href='/';" class="col-md-2 metro-container" style="background-color:##Model.Content.GetPropertyValue("navigationColor")" >
<img class="menu-img" src="../../media/1001/home.png" alt="" />
Home
</div>
</li>
#foreach (var item in menuItems)
{
#* If the Id of the item is the same as the Id of the current page then we want to add the class "current_page_item" *#
#* Otherwise, we set the class to null, that way it will not even be added to the <li> element *#
<li>
<div onclick="location.href='#item.Url';" class="col-md-2 metro-container" style="background-color:##item.Content.GetPropertyValue("navigationColor")" >
<img class="menu-img" src="../../media/1001/home.png" alt="" />
#item.Name
</div>
</li>
}
</ul>
</div>
</div>
So the first "li" outside the loop i simply get the models content Getproperty method which surely enough gets me any property i tell it too.
However the loop i have although goes through the current pages children, i cant seem to get a specific property.
Makes it worse is intellicense Isn't working as its all runtime.
The line in question is
<div onclick="location.href='#item.Url';" class="col-md-2 metro-container" style="background-color:##item.Content.GetPropertyValue("navigationColor")" >
I need to get the color that was set on the page from the navigationColor control.
What am i doing wrong here?
Big derp on my side.
The item var in the foreach loop already has property's contained in the item.
all you need to do is
item.NameofYourPropertyAlias
and that should do it.
The following code works for me:
item[index].GetProperty("name").Value
Makes it worse is intellicense Isn't working as its all runtime.
The problem is that you're using dynamic model instead of the strongly typed kind.
Instead of using CurrentPage you can use Model.Content.
So instead of:
var homePage = CurrentPage.AncestorsOrSelf(1).First();
Use:
var homePage = Model.Content.AncestorOfSelf(1);
Intellisense will then work after you type a stop after homePage.
I would also strongly recommend inputting using Umbraco.web with the rest of your using statements at the top of the template. This should further improve intellisense, and allow you to see methods such as .GetPropertyValue<T>(string alias).
You should then be able to use item.GetPropertyValue<string>("navigationColor").
item.NameofYourPropertyAlias
this is the proper use of item while looping

I'm trying to make an FAQ page. The content structure is like this:
FAQ
-- Question 1
-- Question 2
-- Question 3
I can't seem to work out how to get the child templates to render though (I'm new to this).
FAQ Entries (Parent page)
#inherits Umbraco.Web.Mvc.UmbracoTemplatePage
#{
Layout = null;
var faqContentId = (int)CurrentPage.faqContent;
}
<html>
#Html.Partial("head")
<body>
#Html.Partial("header")
<div class="content">
#{
foreach (var child in Umbraco.Content(1168).Children) {
// render children here
}
}
</div>
#Html.Partial("footer")
</body>
</html>
FAQ Entry (Child pages)
#inherits Umbraco.Web.Mvc.UmbracoTemplatePage
<div class="accordion" id="accordionExample">
<div class="card">
<div class="card-header" id="headingOne">
<h5 class="mb-0">
<button class="btn btn-link" type="button" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
#Umbraco.Field("title")
</button>
</h5>
</div>
<div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">
<div class="card-body">
#Umbraco.Field("answer")
</div>
</div>
</div>
Welcome my dear Umbraco Dev. Let me point you to a few directions:
If you only want the solution, skip to number 3.
1) Refrain from using #inherits Umbraco.Web.Mvc.UmbracoTemplatePage as it will soon be deprecated. Use #inherits Umbraco.Web.Mvc.UmbracoViewPage instead which will get you strongly typed stuff in your view and your code will look like #Model.GetPropertyValue("myValue")
Even better, create a custom model or try using Umbraco ModelsBuilder
which will get you cleaner code and stronger bindings with strongly typed models. But that's for another day.
2) I would recommend not grabbing nodes by id Umbraco.Content('id').Children like this. The reason is that if you for some reason delete the node and then create it again later on with the same name, the id will be different and your code will break the website.
Look at this page where people pointed me to the correct way of traversing umbraco Umbraco traversing
It talks about speed but it basically shows you also the correct way to traverse. you could also find the rest you need within Umbraco's documentation.
3)To the actual question: I'm assuming that the page you're on is the parent and you just want to grab the children. Then it's as easy as :
var collection = Model.Content.Children();
#foreach (var child in collection ) {
child.GetPropertyValue("yourValueAliasHere")
}
if you were using #inherits Umbraco.Web.Mvc.UmbracoViewPage you would have:
var collection = Model.Children();
#foreach (var child in Model.Children()) {
child.GetPropertyValue("yourValueAliasHere")
}
It should be something like #Html.Partial("FAQ Entry", child), where the 2nd parameter is the model (child object) that you want to pass into the partial view.
I have an ASP.Net MVC project that I'm working on and I have a model that I want to turn into I form. I want to use EditorForModel() for this because I want it to automatically add fields to the form if I decide to add/remove properties to the model later.
The problem I'm having is that editor for model takes each property and creates the following HTML: (this is just generic. not the actual code)
<div class="editor-label"><label>Label Title</label></div>
<div class="editor-field"><input type="type"/></div
However what I want it do do for each field is this:
<div class="editor-field">
<label>Label Title</label>
<input type="type"/>
</div>
But if I try to do this in an editor template I get this instead:
<div class="editor-label"><label>Label Title</label></div>
<div class="editor-field">
<label>Label Title</label>
<input type="type"/>
</div>
How can I get EditorForModel() to not make it's own label field? I know I could always style it as hidden in CSS but it'd be nice if it wasn't even there to begin with so I could limit code confusion.
Thanks in advance.
PS: I've also tried using [HiddenInput(DisplayValue = false)] but this just hides the entire field and not just the label.
You need to write this in your editor template cshtml to get it work as expected:
#foreach (var property in ViewData.ModelMetadata.Properties)
{
<div class="editor-field">
<label>#property.GetDisplayName()</label>
#Html.Editor(property.PropertyName)
</div>
}
I'm trying to use the HTMLAgilityPack to retrieve various specific values from a web page. The web page is always the same an the data I want to scrape from it is always in the same place (same divs/classes/attributes etc).
I've tried to loop through and get the values, but I always mess up somewhere. I'd provide some code to help but honestly I've tried 5 times and each time I don't get results close to what I want to - I'm well and truly in a pickle.
I have written the main chunk of HTML:
<div id ="markers">
<div class="row">
<div class="span2 filter-pane ">
<div class="teaser teaser-small">
<h1 class="teaser-title">
...
</div>
<p> Value4 </p>
</div>
</div>
<div class="span2 filter-pane ">
</div>
<div class="span2 filter-pane ">
</div>
</div>
<div class="row"></div>
<div class="row"></div>
</div>
Basically the values (1-4) are the values I want to extract from the data.
The <div id="markers"> is ONE div on the page, all the information I need is in this div.
There are multiple <div class="row"> divs, I need to loop through all of these.
Inside each of these divs, there are three or less <div class="span2 filter-pane "> divs. I need to loop through these 3 divs also.
My data is inside here - Value3 is here in the <p>...</p>. And the other values can be found within the <h1 class="teaser-title"> node, where they are attributes in an <a> element.
I hope somebody can provide me with a solution, or at least some good guidance to accessing all pieces of data I want. I've tried various things but I don't get the results I want.
Thanks.
Here are some hints for you. So first you need to get div#markers because you mentioned that it contains all your info you need.
string mainURL = your url;
HtmlAgilityPack.HtmlWeb web = new HtmlAgilityPack.HtmlWeb();
HtmlAgilityPack.HtmlDocument doc = web.Load(mainURL);
var markerDiv = doc.DocumentNode.Descendants("div").FirstOrDefault(n => n.Id.Equal("markers');
//Check if marketDiv is null or not
//Same idea, get list of row divs
var rows = marketDiv.Descendants("div").HasClass("row") //I will provide .HasClass function or you can write your own, it's simple;
//Iterate throw your rows object
//for each row object
var aElement = row.Descendants("a").FirstOrDefault()//you can have more criteria here if it has more than 1 a element
aElement.GetAttributeValue("data-lat", "") //will return Value1 here, do the same thing for other attributes and p.
Hope it helps
I would like to know what is the best way to send a parameter to a view.
This is my first time with MVC.
I have a menu and I would like to change the item menu class depending which item menu is selected.
For example I have a menu with Home, Products, About.
<div class="nav-main-item">
<a asp-controller="Home" asp-action="About">
<div class="top-solid-line selected"></div>
<div class="row nav-item">
<div class="item-line-1">
Home
</div>
</div>
</a>
</div>
<div class="nav-main-item">
<a asp-controller="Home" asp-action="Products">
<div class="top-solid-line"></div>
<div class="row nav-item">
<div class="item-line-1">
Products
</div>
</div>
</a>
</div>
<div class="nav-main-item">
<a asp-controller="Home" asp-action="About">
<div class="top-solid-line"></div>
<div class="row nav-item">
<div class="item-line-1">
About
</div>
</div>
</a>
</div>
If I select Products I want to add the class 'selected' to it, and remove the class selected to the item menu was selected before an so on.
I know how to do it in jquery, is very simple, but the thing is when I click one of the items menu the selected class continue in the home item menu, that is because I initialize the selected on the Home item menu.
I need some kind of parameter to pass to the view and depending on that value add the class selected to the item menu selected.
I know should be very simple, any help will be appreciate it!
Thanks.
In the controller you can use return View(model), where model is some variable or object. In the cshtml file you can then declare #Model int for instance, when passing an integer and access it like a normal variable as model. For instance: #if (model == 1){ your code here }.
EDIT: you can also add parameters to the ViewBag (google it, there are lots of examples) but I would use the model since it is strongly typed.
ASP.NET MVC Send Multiple Data to View
My opinion
ViewBag, ViewData,TempData is basic solution method exm: (alert, message, script vb. other run client-side code and single data) but write a long code line this dirty and complexible. But using ViewModel property is best solve so your code is not complexible and full compatible Object Oriented Programming architecture.

What would be the best way to add/remove a css class to a div from the controller?
I have a div in a razor view like so (simplified)
<div id="divToToggle" class="hidden">
//content
</div>
In my controller, depending if there is content or not, I want to add or review that class="hidden".
if (model.name.HasAValue())
{
model.company = Method();
//Toggle div to visible here.
}
I have thought about making a new property in the model and setting that value and then in the razor view doing like class="#Model.CssName" However, I have numerous tabs to deal with and don't want to clutter the model up with another set of css properties. What would be the most efficient way to do this?
In view you can do:
<div id="divToToggle" class=#(model.name.HasAValue()?"hidden":"visible")>
//content
</div>
You can also add class, if you have array of class and you want to append in foreach loop
<div class="panel #arrayClass[count1] panel-stat">
</div>
If you have class returning from model
<div class="panel #model.class panel-stat">
<div>
Or you can also use if condition or ternary operator as per your requirement you can do what you want to achieve.
