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(string name, object value)
. When I tried using the Html.TextBoxFor method, my first guess was to try the following which did not work:
<%: Html.TextBoxFor(x => x.Age, new { value = "0"}) %>
Should I just stick with Html.TextBox(string, object) for now?
This question is related to
c#
asp.net-mvc-2
html-helper
you can try this
<%= Html.TextBoxFor(x => x.Age, new { @Value = "0"}) %>
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() })
Try this also, that is remove new { } and replace it with string.
<%: Html.TextBoxFor(x => x.Age,"0") %>
This work for me
@Html.TextBoxFor(model => model.Age, htmlAttributes: new { @Value = "" })
value="0" will set defualt value for @Html.TextBoxfor
its case sensitive "v" should be capital
Below is working example:
@Html.TextBoxFor(m => m.Nights,
new { @min = "1", @max = "10", @type = "number", @id = "Nights", @name = "Nights", Value = "1" })
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")
This should work for MVC3 & MVC4
@Html.TextBoxFor(m => m.Age, new { @Value = "12" })
If you want it to be a hidden field
@Html.TextBoxFor(m => m.Age, new { @Value = "12",@type="hidden" })
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.
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" })
this worked for me , in this way we setting the default value to empty string
@Html.TextBoxFor(m => m.Id, new { @Value = "" })
The default value will be the value of your Model.Age
property. That's kind of the whole point.
