How to pass a query string parameter to ActionLink in MVC

Question

I have a link for the action:

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

How to include data=name in the query string. Something like that:

 link?data=name 

Answer 1

The 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 the URL based on routing, but if the name of the property cannot be matched to any route, it is added as a parameter of the GET URL.

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

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

from the code above.

Answer 2

Skip the query string this way

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

In the above code, you will get url like (Assume Id = 1): /Home/Delete/1

and if you want to add additional parameters to the query string, then:

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

In the above code, you will get url like (Assume Id = 1 and Name = India):

 /Home/Delete/1?Name=India
