Asp.net MVC TextArea

Question

How to size the TextArea and assign Model Value to it in Asp.net Mvc

Answer 1

Try this:

 <%=Html.TextAreaFor(         m => m.Description, 15, 20,          new RouteValueDictionary(new { @class = "someClass"}))%> 

Edit:
This wont work as far as I know

<%=Html.TextAreaFor(m => m.Description, new { cols = "20", rows = "15" })%> 

because of this:

private const int TextAreaRows = 2; private const int TextAreaColumns = 20;  // ...           public static string TextArea(                 this HtmlHelper htmlHelper, string name,                  IDictionary<string, object> htmlAttributes) {             Dictionary<string, object> implicitAttributes = new Dictionary<string, object>();             implicitAttributes.Add("rows", TextAreaRows.ToString(CultureInfo.InvariantCulture));             implicitAttributes.Add("cols", TextAreaColumns.ToString(CultureInfo.InvariantCulture));             return TextAreaHelper(htmlHelper, name, true /* useViewData */, null /* value */, implicitAttributes, null /* explicitParameters */, htmlAttributes);  } 

Answer 2

I found a simple away to achieve this.

Using models annotation razor will be smart enough to generate the textarea.

Model:

[DataType(DataType.MultilineText)] public string Comments { get; set; } 

View:

@Html.EditorFor(model => model.Comments)

Assuming you have a strongly typed view to some model class you could use the following:

<%= Html.TextAreaFor(x => x.SomeProperty, new { rows = "20", cols = "10" }) %>

or:

<%= Html.TextAreaFor(x => x.SomeProperty, 20, 10, new { @class = "foo" }) %>
