how can i render a macro parameter "content picker" inside macro or display the html of the selected content?
Code:
#inherits Umbraco.Web.Macros.PartialViewMacroPage
#{
var carousel = Umbraco.Content(Model.MacroParameters["carouselContent"]);
}
#doctype
Thanks for the help in advance
Umbraco 7.5.5: Its best to make a special DocType with Template for it if you want it to behave as kind of Reusable Content Blocks. Then make a macro with a ContentPicker parameter and put this in it:
#inherits Umbraco.Web.Macros.PartialViewMacroPage
#{
// returns id of content
dynamic contentId = Model.MacroParameters["ContentPicker"].ToString();
if (!string.IsNullOrEmpty(contentId))
{
<div>#Umbraco.RenderTemplate(int.Parse(contentId))</div>
}
}

I'm trying to set a master layout.cshtml page that works consistently for all page except for one or two (typically login and logout). In my layout I'd like to display some elements that I want to not display for these special pages.
I've seen partial views and sections and they all seem to work "backwards" to the way I want - in this case I want the default to be 'display all the elements', but for special pages I want to be able to turn an element off.
I've seen previous code that uses PageData to pass a variable to the layout (which seemed very useful as I could slap a bool in the relevant pages and check it in the layout) but this seems to have been removed. Are there any other ways that work without involving the controller or updating every page to display the bits I want hidden on just 1 page?
There's a number of different ways you can achieve this. If you want to simply "turn off" an area of the page, the simplest approach is probably with ViewData. Something like:
_Layout.cshtml
#if (ViewData["ShowThis"] as bool? ?? true)
{
<!-- HTML here -->
}
This will cause it to default to true (show the HTML) if the ViewData key is not defined, so then in your views where you want to disable it, you'd just need to define it as false:
SomeView.cshtml
#{
ViewData["ShowThis"] = false;
}
Alternatively, you can use sections. This would give you the ability to optionally replace the HTML with something else.
_Layout.cshtml
#if (!IsSectionDefined("Foo"))
{
<!-- HTML here -->
}
else
{
#RenderSection("Foo", required: false)
}
Then, in your view, you simply define the section. If you want to display nothing, you can just define it empty:
SomeView.cshtml
#section Foo {}
Or you can can actually put something in there to replace the area with:
#section Foo
{
<!-- alternate HTML here -->
}
You can try this to pass ViewData in _Layout page in asp.net mvc
public class DynamicMenuAttribute : ActionFilterAttribute
{
public override void OnActionExecuted(ActionExecutedContext filterContext)
{
base.OnActionExecuted(filterContext);
var result = filterContext.Result as ViewResult;
result.ViewData["key"] = "Hello Bangladesh";
}
}
Add Dependency Injection into Startup.cs file
services.AddMvc(
config =>
{
config.Filters.Add(new DynamicMenuAttribute());
}).SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
Now you can you ViewData["key"] in _Layout.cshtml
I am using code like this to detect the browser and apply a condition to display or not display <label>:
#{
var settings = Model.PartFieldDefinition.Settings.GetModel();
System.Web.HttpBrowserCapabilitiesBase theBrow = Request.Browser;
}
<fieldset>
#{
if ((theBrow.Browser == "IE") && (theBrow.MajorVersion < 10))
{
#:<label>#Model.DisplayName</label>
#://Some Code for inputs
}
else
{
#://Some Code for inputs
}
}
</fieldset>
I have been trying to figure out if I can (and if so, how) I could utilize this logic to detect what path in the website the user is in to display or not display <label>
For example, on any other path I want the label displayed. However, for the pages under ~/Services (the path), I want to be able to hide the label.
It's a little bit more complicated than that. The code is in an editor template that gets used all over the site. If I use CSS in the editor template to "hide" the label I will affect all the pages. I was hoping with the above logic I can avoid that and only apply my logic on certain pages under a path.
Thanks.
Update
I have tried the following:
#{
string CurrentURL = Request.ApplicationPath;
}
<fieldset>
#{
if ((CurrentURL == "Services")) // also tried "/Services"
// rest of code left out for brevity
}
but the labels are hidden on all pages, even outside the path "~/Services". Am stuck on the syntax.
Found answer
I did the following:
#{
string CurrentURL = Request.Url.AbsoluteUri;
}
<fieldset>
#{
if (CurrentURL.Contains("Services"))
}
and it worked. I don't know if anyone can comment, but which would be better to use: Request.Url.AbsoluteUri or Request.Url.ToString() (both of which work)?
Hi I have a node events and have 6 types 'eventItem' which are children. On my homepage I want to list all nodes of type eventItem and list the eventDate.
Thanks
Using razor you could do something like the following:
#{
dynamic eventFolder = Library.NodeById(1234);
<ul>
#foreach (var event in eventFolder.Children)
{
<li>#event.eventDate.ToShortDateString() - #event.Name</li>
}
</ul>
}
Obviously, replace "1234" with the actual Id of the event folder and then place the razor script inside a macro and put the macro on your home page's template and you should be good to go.
Given the following Html.ActionLink:
#Html.ActionLink(Model.dsResults.Tables[0].Rows[i]["title"].ToString(), "ItemLinkClick",
new { itemListID = #Model.dsResults.Tables[0].Rows[i]["ItemListID"], itemPosNum = i+1 }, ...
Data from the model contains HTML in the title field. However, I am unable to display the HTML encoded values. ie. underlined text shows up with the <u>....</u> around it.
I've tried Html.Raw in the text part of the ActionLink, but no go.
Any suggestions?
If you still want to use a helper to create an action link with raw HTML for the link text then I don't believe you can use Html.ActionLink. However, the answer to this stackoverflow question describes creating a helper which does this.
I would write the link HTML manually though and use the Url.Action helper which creates the URL which Html.ActionLink would have created:
<a href="#Url.Action("ItemLinkClick", new { itemListID = #Model.dsResults.Tables[0].Rows[i]["ItemListID"], itemPosNum = i+1 })">
#Html.Raw(Model.dsResults.Tables[0].Rows[i]["title"].ToString())
</a>
MVCHtmlString.Create should do the trick.
Using the actionlink below you do not need to pass html in the model. Let the css class or inline style determine how the href is decorated.
#Html.ActionLink(Model.dsResults.Tables[0].Rows[i]["title"], "ItemLinkClick", "Controller", new { #class = "underline", style="text-decoration: underline" }, null)
those are the cases that you should take the other path
#{
string title = Model.dsResults.Tables[0].Rows[i]["title"].ToString(),
aHref = String.Format("/ItemLinkClick/itemListID={0}&itemPosNum={1}...",
Model.dsResults.Tables[0].Rows[i]["ItemListID"],
i+1);
}
#Html.Raw(title)
Remember that Razor helpers, help you, but you can still do things in the HTML way.
You could also use this:
<a class='btn btn-link'
href='/Mycontroler/MyAction/" + item.ID + "'
data-ajax='true'
data-ajax-method='Get'
data-ajax-mode='InsertionMode.Replace'
data-ajax-update='#Mymodal'>My Comments</a>
Consider fallowing declaration in view
#section sideaction
{
...
ViewBag.Title=Model.Title;
...
}
And in main layout i have this
<head>
<title> #ViewBag.Title</title>
....
...
</head>
..
...
<body>
..
#RenderSection("sideaction",required:false)
..
</body>
I am not getting title from view, i know that view will be processed before layout but i recognized that head section is processed before render section which is causing this problem.
One more thing , ViewBag.Title=Model.Title is just an example , the real Model is IEnumrable object and i am iterating and finding proper title. I can iterate in controller to find title but there is already iteration in view. For big collections one iteration is more efficient.
Any ideas?
You cannot set a ViewBag value in a section.
Use this:
#{
ViewBag.Title = Model.Title;
}
directly in the view to set a title.
Even it doesn't work, notice that the code has to be like this:
#section sideaction
{
#{
ViewBag.Title = Model.Title;
}
}
But as other people mentioned earlier, you can't do it this way inside a section.
You should put it directly inside your view:
#{
ViewBag.Title = Model.Title;
}
By the way, if you persist to change title of a page from inside a section, use javaScript/jQuery, e.g:
#section sideaction
{
<script type="text/javascript">
$(function () {
document.title = '#Model.Title';
});
</script>
}
Note: pay attention that it has to be '#Model.Title' (inside quotes).
