How to force uppercase on a Html.TextboxFor

For EditorFor:

@Html.EditorFor(model => 
    model.Nome, 
    new { 
        htmlAttributes = new { 
            @class = "form-control", 
            @onkeyup = "InputToUpper(this);"
        } 
    }
)

The easiest way is IMO:

@Html.EditorFor(m => m.TechnologyID, new { htmlAttributes = new { @style = "text-transform:uppercase" } })
