How to set a default value with Html.TextBoxFor?

Question

Simple question, if you use the Html Helper from ASP.NET MVC Framework 1 it is easy to set a default value on a textbox because there is an overload Html.TextBox(strin

Answer 1

you can try this

<%= Html.TextBoxFor(x => x.Age, new { @Value = "0"}) %>

Answer 2

Using @Value is a hack, because it outputs two attributes, e.g.:

<input type="..." Value="foo" value=""/>

You should do this instead:

@Html.TextBox(Html.NameFor(p => p.FirstName).ToString(), "foo")

Answer 3

You can simply do :

<%= Html.TextBoxFor(x => x.Age, new { @Value = "0"}) %>

or better, this will switch to default value '0' if the model is null, for example if you have the same view for both editing and creating :

@Html.TextBoxFor(x => x.Age, new { @Value = (Model==null) ? "0" : Model.Age.ToString() })

Answer 4

This work for me

@Html.TextBoxFor(model => model.Age, htmlAttributes: new { @Value = "" })

Answer 5

Here's how I solved it. This works if you also use this for editing.

@Html.TextBoxFor(m => m.Age, new { Value = Model.Age.ToString() ?? "0" })

Answer 6

If you have a partial page form for both editing and adding, then the trick I use to default value to 0 is to do the following:

@Html.TextBox("Age", Model.Age ?? 0)

That way it will be 0 if unset or the actual age if it exists.
