What is the best way to add content to a TextArea generated by the html helper in MVC 3?

Question

What is the best way to add content to a TextArea generated by the html helper in MVC 3?

I am attempting to retrieve a List collection of comments from the View using Razor and Microsoft's HTML helper for TextArea (@Html.TextAreaFor). While I can populate individual comments easily, I am unsure how to add the ENTIRE list collection of comments to the textarea. Below is an example of how I display single comments:

@Html.TextAreaFor(x => x.AuditDoc.PrivateComment, 0, 0, false)

While this works for displaying single comments, I am looking for a way to append multiple comments (second, third, fourth, etc.) to that SAME textarea. Is there a method to bind an entire list collection to the html.textarea helper? Ideally, I would like to achieve this in Razor using html helpers. If this proves to be impossible, any guidance on achieving it with jQuery would be appreciated. It is important to note that the comments do not need to be linked to the model, so simply using @Html.TextArea instead of @Html.TextAreaFor would suffice. The array of comments is purely for display purposes, eliminating complications such as multi-select, etc.

Answer №1

One approach is to concatenate the comments in the controller before passing them to the view for display:

Controller Logic:

var comments = db.Comments.ToList();
string concatComments = string.Empty;
foreach (var item in comments)
{
    concatComments = concatComments + item.Title;
}
ViewData["ConcatenatedComments"] = concatComments.ToString();

Then, in the View, you can use the following code:

@Html.TextArea("Comments", ViewData["ConcatenatedComments"].ToString())

You might want to consider formatting the concatenated comments for better readability by adjusting your concatenation logic like so:

concatComments = concatComments + " " + item.Title;

If you're looking to optimize your approach, consider these suggestions:

Consider creating a distinct property in the view model that consolidates all comments, then link this to the text area.
For a more streamlined solution, opt for an editor template dedicated to the collection property.
