I have tried different syntax as belows.
"<img src='../Images/Live news/Actions-arrow-right-icon.png' />" ;
<img src="<%= Url.Content("~/Images/Live news/Actions-arrow-right-icon.png") %>"
I want to add image through controller not view so is these syntex are correct?
This is my full code
dt = Users.Get_Livenews(0, true, "GActive");
for (int i = 0; i < dt.Rows.Count; i++)
{
objExercise = new HomeModel();
objExercise.livenews = Convert.ToString(dt.Rows[i]["livenews_headline"].ToString()) + "<img src='../Images/Live news/Actions-arrow-right-icon.png' />" ;
Horizontal.Add(objExercise);
}
You should get the list of image paths from controller and then iterate the this list at View level. Means dynamically create images for each image path you iterate.
If your view is strongly-typed and controller returns view with model or say list object then using for or foreach loop, you can prepare table or whatever you need.

I need to send a list of model objects to my partial page and I need to bind the same. But I am not able to bind dropdown with my model object.
With the below code I am not able to bind my dropdown, but the same code is working if I use ViewBag.
#model MyProject.Models.BindDropdown
#for (int i = 0; i <= Model.Count; i++)
{
#Html.DropdownListFor(m => m[i].MyID, new SelectList(m = > m[i].List),"MyID")
}
When I try to write m[i].List I get this error
Cannot convert lambda expression to type System.Collections.IEnumerable because it is not a delegate type
I have a partial view in mvc3 for rendering tbody content.
So how can I pass count vale in partial view and get counter value in my Serial Number column
PartialViews can have Models assigned to them just like regular views:
#model Namespace.SubNamespace.Folder.ClassName
Then, you can call Html.Partial and pass a new instance of that model:
#Html.Partial("ViewName", new ClassName() {//set values here});
If you do this, you can calculate the number of rows before the partial call and use that elsewhere:
#{
var numRows = dataSource.Rows.Count(); //use whatever count method you like
}
Meaning you can calculate the row count and set it as part of the PartialView's view model:
#{
var numRows = dataSource.Rows.Count(); //use whatever count method you like
}
#Html.Partial("ViewName", new ClassName() {RowCount = numRows});
I'm using Sitecore 7.2 with MVC and a component approach to page building. This means that pages are largely empty and the content comes from the various renderings placed on the page. However, I would like the search results to return the main pages, not the individual content pieces.
Here is the basic code I have so far:
public IEnumerable<Item> GetItemsByKeywords(string[] keywords)
{
var index = ContentSearchManager.GetIndex("sitecore_master_index");
var allowedTemplates = new List<ID>();
IEnumerable<Item> items;
// Only Page templates should be returned
allowedTemplates.Add(new Sitecore.Data.ID("{842FAE42-802A-41F5-96DA-82FD038A9EB0}"));
using (var context = index.CreateSearchContext(SearchSecurityOptions.EnableSecurityCheck))
{
var keywordsPredicate = PredicateBuilder.True<SearchResultItem>();
var templatePredicate = PredicateBuilder.True<SearchResultItem>();
SearchResults<SearchResultItem> results;
// Only return results from allowed templates
templatePredicate = allowedTemplates.Aggregate(templatePredicate, (current, t) => current.Or(p => p.TemplateId == t));
// Add keywords to predicate
foreach (string keyword in keywords)
{
keywordsPredicate = keywordsPredicate.And(p => p.Content.Contains(keyword));
}
results = context.GetQueryable<SearchResultItem>().Where(keywordsPredicate).Filter(templatePredicate).GetResults();
items = results.Hits.Select(hit => hit.Document.GetItem());
}
return items;
}
You could create a computed field in the index which looks at the renderings on the page and resolves each rendering's data source item. Once you have each of those items you can index their fields and concatenate all of this data together.
One option is to do this with the native "content" computed field which is natively what full text search uses.
An alternative solution is to make an HttpRequest back to your published site and essentially scrape the HTML. This ensures that all renderings are included in the index.
You probably will not want to index common parts, like the Menu and Footer, so make use of HTMLAgilityPack or FizzlerEx to only return the contents of a particular parent container. You could get more clever to remove inner containers is you needed to. Just remember to strip out the html tags as well :)
using HtmlAgilityPack;
using Fizzler.Systems.HtmlAgilityPack;
//get the page
var web = new HtmlWeb();
var document = web.Load("http://localsite/url-to-page");
var page = document.DocumentNode;
var content = page.QuerySelector("div.main-content");
I'm having trouble converting text to a hyperlink in a controller, then sending it to the view.
So far, I have:
Controller:
foreach (dynamic tweet in Timeline())
{
string text = tweet["text"].ToString();
const string pattern = #"http(s)?://([\w+?\.\w+])+([a-zA-Z0-9\~\!\#\#\$\%\^\&\*\(\)_\-\=\+\\\/\?\.\:\;\'\,]*)?";
Regex regexCheck = new Regex(pattern);
MatchCollection matches = regexCheck.Matches(text);
for (int i = 0; i < matches.Count; i++)
{
text = string.Format(#"<a href={0}>{1}</a>", matches[i].Value, matches[i].Value);
}
timeline.Add(text);
}
View:
#Html.DisplayFor(model => model.Timeline)
But It keeps displaying the literal text!
Display: <a href=http://t.co/fm0ruxjVXe>http://t.co/fm0ruxjVXe</a>
Could anyone please show me how this is done? I am quite new to MVC.
since you are sending out html already, try
#Html.Raw(Model.Timeline)
Another option is to send out just the url and the text and build the a tag in the view
#Model.Timeline.Text
That will involve changing your timeline property to being an object with two properties, text and url .
The #Html.DisplayFor helpers in Razor automatically encode the output
If you want to just output the content of model.Timeline, try just using Response.Write
If my urls looks like:
www.mysite.com/1/home
www.mysite.com/1/other-action
www.mysite.com/1/another-action/?value=a
how can I switch the 1 parameter while invoking the same action with the same parameters and querystring values?
For example if I'm currently browsing
www.mysite.com/1/another-action/?value=a
I would like to obtain the necessary links to switch to
www.mysite.com/2/another-action/?value=a
.
.
www.mysite.com/x/another-action/?value=a
Url.Action seems not to help...
The general idea is clone the current RouteValueDictionary, change one value, and then build a new action link based on the new RouteValueDictionary. Here's an example. But you'd probably want to do this in a URL helper, rather than directly in the view:
<% var foo = new RouteValueDictionary();
foreach (var value in ViewContext.RouteData.Values)
{
foo.Add(value.Key, value.Value);
}
foo["id"] = 2;
var newUrl = Url.Action(foo["action"].ToString(), foo); %>
I would propose small optimization to Craig's answer:
<% var foo = new RouteValueDictionary(ViewContext.RouteData.Values);
foo["id"] = 2;
var newUrl = Url.Action(foo["action"].ToString(), foo); %>
