The problem is that your anonymous object property data-icon has an invalid name. C# properties cannot have dashes in their names. There are two ways you can get around that:

Use an underscore instead of dash (MVC will automatically replace the underscore with a dash in the emitted HTML):

@Html.ActionLink("Edit", "edit", "markets",
new { id = 1 },
new {@class="ui-btn-right", data_icon="gear"})

Use the overload that takes in a dictionary:

@Html.ActionLink("Edit", "edit", "markets",
new { id = 1 },
new Dictionary<string, object> { { "class", "ui-btn-right" }, { "data-icon", "gear" } });

Replace the desired hyphen with an underscore; it will automatically be rendered as a hyphen:

@Html.ActionLink("Edit", "edit", "markets",
new { id = 1 },
new {@class="ui-btn-right", data_icon="gear"})

becomes:

<form action="markets/Edit/1" class="ui-btn-right" data-icon="gear" .../>

@Html.ActionLink("display name", "action", "Contorller"
new { id = 1 },Html Attribute=new {Attribute1="value"})

@Html.ActionLink("Login", "Index", "hahgshg62jjshags",new { },new { rel = "nofollow", style = "color:white" })
