如何使用Html.TextBoxFor（C＃）设置默认值，使其符合W3C标记？

Question

I am setting a default value with the following code:

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

The problem is the generated code contains two value attributes, breaking W3C markup validation.

<input Value="0" data-val="true" data-val-required="Age is required." id="Age" name="Age" type="text" value="" />

Notice the capital 'V' and the lowercase 'v' value attributes...

Does anyone know of a work around for the html helper TextBoxFor to only have one value attribute??

Answer 1

Get rid of the "new { @Value = "0"}" and just use the following...

@Html.TextBoxFor(m => m.Age)

The value of the input will be whatever value the Age property of the model is. If you want the default value to be 0, than set the age property of the model to 0.

Answer 2

This happen because the Value is not the the same attribute the value , HTML 5 is case sensitive and the Html.TextBoxFor give the output rightly (considering value is the right and Value a custom).

Try:

@Html.TextBoxFor(m => m.Age, new { @value = "0"})
