For asp.net-mvc routing, my link is this:
<a href='product/product_description/#:product_id#' >
but it is passing as this:
http://localhost:58166/product/product/product_description/1102
I expected it to be:
http://localhost:58166/product/product_description/1102
What am I doing wrong?
You need to perpend forward slash
<a href='/product/product_description/#:product_id#' >
However you would be much better off using a helper rather than hard coding
#Html.ActionLink("Link text", "product_description", "product" { new ID = ?? })

Hi I have created a mvc website which is working fine with localhost if i am coding something like this:
<base href="http://localhost:5400/" />
<li><a class="home" href="/Home/Index/">Home</a></li>
<li class="wish"><a class="wishlist" href="/Products/Index/" id="wishlist-total">Products</a></li>
<li><a class="account" href="/Home/Contact/">Contact Us</a></li>
But now to run it on live if i am trying to changing this:
<base href="http://localhost:5400/" />
with this:
<base href="HttpContext.Current.Request.Url" />
then its actually taking full root url everytime.So whenever i am clicking on any menu and moves to next menu it regain previous menu path also.
For this issue i tried below code which is also not working.
<li>Home</li>
<li>Products</li>
<li> Contact</li>
According me this code will work,But if i am trying to pass "null" as third parameter then i gives error:
ERROR: 'null' is not declared. 'Null' constant is no longer supported; use 'System.DBNull' instead.
Can someone please suggest what i should need to change?
Thanks
Quick fix...
#Url.Action("Index", "Home")
There's no need to enter null as a parameter... if you want to indicate that a parameter can be null, then you need to define that in the route its self, and if the parameter is missing, then it will know that the value is null implicitly...
// http://yoursite/Example/{id}
[Route("~/Example/{id}"] // Can't be null
public ActionResult Example(string id){ return View(); }
// http://yoursite/ExampleTwo/
[Route("~/ExampleTwo/{id?} // Can be null
public ActionResult ExampleTwo(string id) { return View(); }
TLDR if you want more errors...
Your issue is actually indicating a much larger issue... it looks as if you're accepting a query from a URI directly into a SQL query... if you are doing that, you're opening yourself up to injection attacks and as much as a part of me feels that anyone who does that pretty much has it coming to them... I can't stand by and just say nothing... sanitize any data that you receive from the user, no matter where it's coming from, example
Remove all those magic strings... you shouldn't have any strings such as the one you just displayed...
// Bad...
<a class="home" href="/Home/Index/">
// Better...
<a class="home" href="#Url.Action("Index", "Home")">Home</a>
// Good
#Html.ActionLink("Home", "Index", "Home")
I have this code HTML:
<a class="tooltip-tip2 ajax-load" href="...."><i class="entypo-menu"></i><span>Page Example</span></a>
And I would use this:
#Html.ActionLink("Crea mensilizzazione " + s.nome, "CheckCredentials", "giornaliero", new { #class= "tooltip-tip2 ajax-load" , id=s.id, isScuole = false},null)
How can add the <i class="entypo-menu"></i> in this #HTML.ActionLink???
I don't think the ActionLink helper can accomplish this. but you can use #Url.Action() in custom markup to accomplish the same thing:
<a class="tooltip-tip2 ajax-load" href="#Url.Action("CheckCredentials", "giornaliero")"><i class="entypo-menu"></i><span>Page Example</span></a>
Url.Action basically just creates the URL for the link, not any of the markup related to building the link itself. So it can be used in all sorts of custom client-side code. (For example, another common use is to embed it in some JavaScript code to define an AJAX service URL.)
Edit: You can add route values exactly the same way as you do with #Html.ActionLink:
#Url.Action("CheckCredentials", "giornaliero", new { id = s.id, isScuole = false })
How could I correctly use the following?
{ bool submitter = value; }
...
#(submitter ? "" : #"<a href=""" + Url.Action(actionName, "Queue") + #""">")
<div>
...
</div>
#(submitter ? "" : "</a>")
My error is that the anchor tag definition is being outputed like it should be in a HTML code right to the web browser and instead of seeing a link around the <div> I see the <a href="... etc.
Why?
If you don't want that encoded, then you need to use the Raw extension method:
#Html.Raw(submitter ? "" : #"<a href=""" + Url.Action(actionName, "Queue") + #""">")
<div>
...
</div>
#Html.Raw(submitter ? "" : "</a>")
This is because you cannot put block level elements, like div, inside inline elements like a, unless you use HTML5. I guess from your description you aren't.
If you're checking in a browser DOM inspector, you will see your code looks something like this:
<div></div>
<div></div>
<a></a>
The alternative is to change your div to span and set display: block on it in CSS if you require.
Also, that kind of logic would be better placed in a ViewModel.
Solution that I've: found
#(new MvcHtmlString(#"blah blah"))
I have some tabs, and I want to say "if they are currently on the page that this tab refers to, make this a span. Otherwise, make this a link." In pseudo-razor, that would look like this:
#if(CurrentlyOnThisPage) {
<span>
} else {
<a>
}
Tab Content
#if(CurrentlyOnThisPage){
</span>
} else {
</a>
}
Razor (correctly) notes that I'm not closing my beginning tags, and so has trouble parsing this syntax. If the tab content was small, I could use Html.ActionLink, but I've got a few lines of stuff and I'd like to keep the benefits of the HTML editor rather than putting it all into a string. Is there any way to do this?
You can write the tags as literal text to prevent Razor from parsing them:
#:<span>
How about something like this?
#{
var linkOrSpan= CurrentlyOnThisPage ? "span" : "a";
}
<#linkOrSpan><text>Tab Content</text></#linkOrSpan>
No errors about closing tags with this.
Looks a bit cleaner too ihmo.
HTH
Or just write it out explicitly:
#if(CurrentlyOnThisPage)
{
<span>tabcontent</span>
} else {
<a>tabcontent</a>
}
All,
Doing some experimenting with Spark and MVC within NerdDinner. The normal/aspx view works well, and I haven't touched any of the controller code so I'm pretty sure it's not that.
<viewdata model="System.Collections.Generic.IEnumerable[[NerdDinner.Models.Dinner]]"/>
<set Title="'Upcoming Dinners'"/>
<content:main>
<li each="p in Model">
!{Html.ActionLink(p.Title, 'Details', 'Dinners')}
</li>
</content:main>
Given the code above, the ActionLink gets rendered as http://serverName/Controller/Action/
Which is good. I start hitting a wall when I try to provide the ID to my action method. As far as I can tell from the Spark sample docs, I should be able to do something like this:
!{Html.ActionLink(p.Title, 'Details', 'Dinners', new {id = p.DinnerID} )}
However, that throws an exception:
" unexpected token '{' "
I'm hoping it's something silly I'm missing...any suggestions?
I believe there should be another parameter to Html.ActionLink for HTML attributes on the action link. Try:
!{Html.ActionLink(p.Title, 'Details', 'Dinners', new {id = p.DinnerID}, null )}
