How to pass query string parameter in ActionLink in MVC

Question

I am having following action link:

<%= Html.ActionLink(\"Check this\", \"Edit\", \"test\", 
                     new { id = id }, new { style = \"display:bloc         


        

Answer 1

I know this is kind of old question but.

In case the below code doesn't generate the <a href="/?param=value" />.

<%= Html.ActionLink("Text", "Action", "Controller", new { param=value }, null)%>

I would advice checking whether you action has at least one [Route] attribute (I used [Route("/")] for example).

Hope it helps.

Answer 2

Pass Query String By this way

@Html.ActionLink("Delete Record", "Home", "Delete", new { id=Id},null)

By above code you will get the url like(Suppose Id=1): /Home/Delete/1

and if you want to add more parameters to query string then:

@Html.ActionLink("Delete Record", "Home", "Delete", new { id=Id, Name=name},null)

By above code you will get the url like(Suppose Id=1 and Name=India) :

/Home/Delete/1?Name=India

Answer 3

4th parameter of Html.ActionLink can have any number of properties:

<%= Html.ActionLink("Check this", "Edit", "test", 
                     new { id = id, data=name }, new { style = "display:block" })%>

These properties are inserted into URL based on routing, but if the property name cannot be matched into any route it is added as URL GET parameter.

So if you have standard route {controller}/{action}/{id}, you will get the URL:

test/Edit/[id]?data=[name] 

from the above code.

Answer 4

I got tired of banging my head against a wall with the html.actionlink. Works great when you just want to route it against straightforward routing calls, but absolutely refuses to cooperate when you want to add a simple querystring at the end.

I don't an ID at then end, I want to be able to add some kind of actual Querystring with the "?".

So anywhere I needed a Querystring I switched to using the url.action inside the anchor tag.

<a href='@url.action("Action","route")?Parameter=Value' >Text for Link Name</a>

At least it works and I can stop getting headaches over something that should have been a very simple task. Someone needs to get their heads out of their butts and make the ActionLink work properly for Querystrings in the MVC routing.
