New to Razor and I am missing somethign simple here:
#foreach (var p in #Model)
{
<a href="/category/#Html.Display("CategoryID")" >
<img src="http://images.mydomain.com/productimages/#ViewData["ManufacturerID"]/category-#Html.Display("CategoryID")_lg.jpg?width=200&height=130" width="200" height="130" class="myImg" alt="" />
</a>
}
I simply want to out put the CategoryID here, the link above does not output a value for CategoryID. What am I doing wrong here?
My model is populated since I can drop this in the loop and it displays: #p.CategoryName
Try this.
#foreach (var p in #Model)
{
<a href="/category/#p.CategoryID" >
<img src="http://images.mydomain.com/productimages/#ViewData["ManufacturerID"]/category-#(p.CategoryID)_lg.jpg?width=200&height=130" width="200" height="130" class="myImg" alt="" />
</a>
}
We are using explicit expression inside the image source string ( #(p.CategoryID) )
In your link href just use #p.CategoryID. The Html.Display() is used to show value from model's property. Your model doesn;t contains CategoryID property because it's a collection.

I have a HTML table with 2 rows and 4 columns. The data in each cell is coming from the stored proc. Currently, the last column displays number, I have an image to display, but it has to be displayed only if(rejected_question>0) else it should not display anything. How do I accomplish this in razor.
I have tried this so far, the below code doesn't work:
#foreach (var item in Model)
{
//logic for first three columns..
//fourth column here.
<td align="center">
if(#Html.DisplayFor(modelItem => item.RejectedQuestion) >0)
{
return Html.Raw(string.Format("<text><img height='3' width='3' src="\{0}\" alt="\Image\" /></text>", Url.Content("../../content/images/icon_red_questions_returnedbyreviewer.gif")));
}
</td>
}
This is what your looking for, probably:
#foreach (var item in Model)
{
//logic for first three columns..
//fourth column here.
<td align="center">
#if(item.RejectedQuestion > 0)
{
<img height="3" width="3" alt="Image"
src="#Url.Content("~/content/images/icon_red_questions_returnedbyreviewer.gif")" />
}
</td>
}
Make the line inside the if statement
#Html.Raw(string.Format("<text><img height='3' width='3' src="\{0}\" alt="\Image\" /></text>", Url.Content("../../content/images/icon_red_questions_returnedbyreviewer.gif")))
to display it. view.Execute() returns void, so you cannot include a return statement.
I tried this and it worked, just in case if someone needs it in future
:
#if(item.RejectedQuestion > 0)
{
<img height="20" width="20" alt="Image"
src="#Url.Content("~/content/images/icon_red_questions_returnedbyreviewer.gif")" />
}
I've added a Custom Field to the List Widget in Sitefinity 8.1, it's Type is Related data and it's Data type is Pages. The field name is LinkedPageUrl.
Works perfectly in the back end allowing me to select a page from system and store it against that particular List Item.
I can't find any place in Sitefinity's documentation that explains how I would programmatically use this field in a MVC based List.SimpleList.cshtml view template that I'm customizing.
I've seen this being used in the News widget where there is an associated Image for each News Article:
<img src="#Html.Raw(item.Fields.RelatedImg.Fields.MediaUrl)" class="img-responsive" />
But I don't get close to this because I don't have the slightest idea where to begin... What's the model structure, syntax, etc.
My objective is to change each list item rendered out into an anchor and the anchor should make use of this Related Data field's URL for it's Href property.
EDIT:
You can do something like this in the widget template:
#foreach (var item in Model.Items)
{
<h3 #Html.InlineEditingAttributes(Model.ProviderName, Model.ContentType.FullName, (Guid)item.Fields.Id)
#Html.InlineEditingFieldAttributes("Title", "ShortText")>
#item.Fields.Title
</h3>
<ul>
#foreach (var listItem in ((ListViewModel)item).ListItemViewModel.Items)
{
<li #Html.InlineEditingAttributes(Model.ProviderName, ((ListViewModel)item).ListItemViewModel.ContentType.FullName, (Guid)listItem.Fields.Id)>
<div #Html.InlineEditingFieldAttributes("Title", "ShortText")>
#listItem.Fields.Title
</div>
<div class="sfMultiRelatedItmsWrp">
<h2 class="sfrelatedItmTitle">Related pages</h2>
#foreach (var link in listItem.Fields.LinkedPageUrl)
{
var node = PageManager.GetManager().GetPageNode(link.Fields.Id);
var url = PageExtesnsions.GetFullUrl(node);
<div>#link.Fields.Title - #url</div>
}
</div>
</li>
}
</ul>
}
This is given that you selected that multiple pages can be selected per list item.
EDIT: Make sure to include the following namespaces
#model Telerik.Sitefinity.Frontend.Mvc.Models.ContentListViewModel
#using Telerik.Sitefinity.Frontend.Lists.Mvc.Models;
#using Telerik.Sitefinity.Frontend.Mvc.Helpers;
#using Telerik.Sitefinity.Modules.Pages;
EDIT2: If the custom field allows for only 1 page to be selected then it should look like this:
<div class="#Model.CssClass">
#foreach (var item in Model.Items)
{
<h3 #Html.InlineEditingAttributes(Model.ProviderName, Model.ContentType.FullName, (Guid)item.Fields.Id)
#Html.InlineEditingFieldAttributes("Title", "ShortText")>
#item.Fields.Title
</h3>
<ul>
#foreach (var listItem in ((ListViewModel)item).ListItemViewModel.Items)
{
<li #Html.InlineEditingAttributes(Model.ProviderName, ((ListViewModel)item).ListItemViewModel.ContentType.FullName, (Guid)listItem.Fields.Id)>
<div #Html.InlineEditingFieldAttributes("Title", "ShortText")>
#listItem.Fields.Title
</div>
<div class="sfMultiRelatedItmsWrp">
<h2 class="sfrelatedItmTitle">Related pages</h2>
#{
var node = PageManager.GetManager().GetPageNode(listItem.Fields.LinkedPageUrl.Fields.Id);
var url = PageExtesnsions.GetFullUrl(node);
}
<div>#listItem.Fields.Title - #url</div>
</div>
</li>
}
</ul>
}
A good starting point is this article
I have been able to bind the info to the textbox like so:
<div id="wordsInsideOfText">
#foreach (var item in Model.KVpairs)
{
#Html.TextBoxFor(modelItem => item)
<hr />
}
</div>
but what I am trying to do is something like this:
<div id="wordsInsideOfText">
#foreach (var item in Model.KVpairs)
{
#Html.TextBoxFor().PlaceHolder(modelItem => item)
<hr />
}
</div>
So that I can get the information from my model into the placeholder rather than as regular text.I have looked around some, and maybe I don't fully understand how to phrase my question/search but I wasn't able to come up with anything.
you have to do like this:
#Html.TextBoxFor(modelItem => item, new {placeholder = item})
or:
<input type="text" placeholder="#item"/>
I have the following code:
foreach (var interest in Model.Interests)
{
<div>
<span>#interest.SubjectName</span>
#if (interest.Description.Length > 2)
{
<a data-bind="click(DATA)" href="#" title="View Details">details</a>
}
</div>
}
I'm using Razor because I need to allow users without javascript to have read-only access to the site, so using a knockout/JS loop here isn't an option.
In this line:
<a data-bind="click(DATA)" href="#" title="View Details">details</a>
I'd like to take the current interest (razor object) and send it into the click function. I just don't know the syntax.
How can this be achieved?
Depends on what representation of the object you want to pass to your function. If JSON will suffice, try this:
<a data-bind='#String.Format("click({0})", Newtonsoft.Json.JsonConvert.SerializeObject(interest))'
href="#" title="View Details">details</a>
Then in your click function you can get the object like this:
function click(data) {
var interest = JSON.parse(data);
}
I have a sortable list of items which are generated from an array property on a model. I want to use jquery UI sortable to reorder the items and save this order in my Action method.
Here is the code I am using to output the items:
#using(#Html.BeginForm("Save", "MyController", FormMethod.Post))
{
<input type="submit" value="Save"/>
#Html.HiddenFor(x=>x.Id)
<ul id="sortable2" class="connectedSortable">
#{
int count = 0;
}
#foreach(var item in Model.CollectionOfThings)
{
<li class="ui-state-default">
#Html.Hidden("Things[" + count + "].Id", item.Id)
#Html.Hidden("Things[" + count + "].Title", item.Title)
#item.Title
</li>
count++;
}
</ul>
}
When I receive the model in my action method the order is the same as when I started. I understand that this is because of the index but I can't figure out a way (without writing some custom javascript to update the name attribute of each hidden input) to have the items bound to the array in correct order.
Can anyone suggest a way this could be achieved? I can probably write a bit of Javascript to do it but I hoped I could do this purely with model binding.
I tried outputting the inputs like this:
#Html.Hidden("Things[].Id", item.Id)
However this just resulted in my collection being null.
I have discovered a blog post from Phil Haack which contained the answer.
By using arbitrary indexes in a seperate hidden input with the name of my collection + .Index, the model binder seems to handle it and maintain the order.
#using(#Html.BeginForm("Save", "MyController", FormMethod.Post))
{
<input type="submit" value="Save"/>
#Html.HiddenFor(x=>x.Id)
<ul id="sortable2" class="connectedSortable">
#{
int count = 0;
}
#foreach(var item in Model.CollectionOfThings)
{
<li class="ui-state-default">
#Html.Hidden("Things.Index", "item" + count)
#Html.Hidden("Things[item" + count + "].Id", item.Id)
#Html.Hidden("Things[item" + count + "].Title", item.Title)
#item.Title
</li>
count++;
}
</ul>
}
Easier solution for you can be to collect only Ids. I assume titles can be recreated on server side. In this case you can just define:
#Html.Hidden("ThingIds", item.Id)
and bind to
List<int> thingsIds
