Question

Ive got an Html.TextBoxFor that is used to represent a Double. When I generate “Create” View

@Html.TextBoxFor(Function(model) model.Longitude)

The <input> has a default value of “0”

I have tried modifying it in two ways

@Html.TextBoxFor(Function(model) model.Longitude, New With {.value = ""})

and in the controller

Dim model As Domain.Event = New Domain.Event
With model
    .Longitude = String.Empty
End With

Return View(model)

But neither of these work.

How can I have the input “Blank” for a numeric input?

Answer 1

You could use a Nullable(Of Double) type or double? in C#.
