ASP.NET MVC FormCollection TextArea

I have a textarea that represents a description field. The descriptions have commas so when trying to split the field's descriptions the data is not parsed correctly. How can I get each row's description correctly.

     var DescList = FormValues["Item.Description"].Split(',').Select(item => item).ToList<string>();
//will not work for obvious reasons. Comma delimited FormCollection has commas to identify separate row data.

It seems like Microsoft designed the FormsCollection without the textarea control in mind. A text area with commas will not work when trying to access each value. What is interesting is that the _entriestables property has it in the perfect format but they chose to make it a private property. Very frustrating.

Here is the important part of my viewmodel.
 public class TenantViewModel
{
    public Tenant Tenant { get; set; }
                public Site Site { get; set; }

    }

My view is populated like this:

    if (Model != null && Model.Tenant != null && Model.Tenant.Site != null开发者_如何学编程 && Model.Tenant.Site.Count() > 0)
    {<div class="detailsbox_view">
        <table id="tblTenantSites">
            <tr>
                <th>@Html.LabelFor(item => item.Site.Title)</th>
                <th>@Html.LabelFor(item => item.Site.Description)</th>

            </tr>
        @foreach (var Item in Model.Tenant.Sites)
           {
            <tr>
                @Html.HiddenFor(modelItem => Item.SiteId)


                <td>
                    @Html.EditorFor(modelItem => Item.Title)
                                        </td>
                <td>
                    @Html.TextAreaFor(modelItem => Item.Description, new {@width="400" })

                </td>

            </tr>   }
        </table>

As you see this site table is a child of Tenant object. This child record does not get automatically updated using this method but the Tenant data does automatically get updated. This is the reason I tried the FormColelction instead. Is there something I am missing to make this work?

try with this useful function

ValueProviderResult Match=FormCollection.GetValue("ValueProvider");

When you have multiple fields with the same name attribute, they'll come back into your FormCollection as an array. So upon posting a view like this:

<form action="/Home/MyAction">
    <textarea id="row_one_description" name="description">
        First row's description
    </textarea>
    <textarea id="row_two_description" name="description">
        Second row's description
    </textarea>

    <input type="submit" value="Submit" />
</form>

you could do something like this in your action

[HttpPost]
public ActionResult MyAction(FormCollection collection) 
{
    var descriptionArray = collection["description"];

    string firstRowDescription = descriptionArray[0];
    string secondRowDescription = descriptionArray[1];
}

I must note that this is not the recommended way of dealing with posted data. You should instead be building your view using data from a view model and using strongly typed html helpers to render your controls. That way when you post, your action can take the ViewModel as a parameter. Its properties will be automatically bound and you will have a nice object to play with.

[HttpPost]
public ActionResult MyAction(MyViewModel viewModel) 
{
    foreach (var row in viewModel.Rows)
    {
        string description = row.Description;
    }
}

EDIT
I'm still assuming a lot about your ViewModel but perhaps try this:

<table id="tblTenantSites">
    <tr>
        <th>@Html.LabelFor(model => model.Site.Title)</th>
        <th>@Html.LabelFor(model => model.Site.Description)</th>
    </tr>

    @for (var i = i < Model.Tenants.Sites.Count(); i++) {
    <tr>
        @Html.HiddenFor(model => model.Tenants.Sites[i].SiteId)

        <td>
            @Html.EditorFor(model => model.Tenants.Sites[i].Title)
        </td>
        <td>
            @Html.TextAreaFor(model => model.Tenants.Sites[i].Description, new { @width="400" } )
        </td>

    </tr>   
    }

</table>

You could also try ,

   string Match=FormCollection.GetValue("ValueProvider").AttemptedValue;
