You can try following way, if you would like to load textarea from your ViewBag

Controller:

public IActionResult Index()
        {
            var dsplayModelList = new List<DsplayModel>()
            {
                new DsplayModel() { UserComment="This is some comment from viewbag"},
                new DsplayModel() { UserComment="This is another comment from viewbag"},

            };
            ViewBag.Controls = dsplayModelList;
            return View();
        }

View:

@model DotNetWebApp.Models.DsplayModel

@foreach (DsplayModel display in ViewBag.Controls)
{

    @using (Html.BeginForm("ControllerAction", "ControllerToPost", FormMethod.Post))
    {
        <textarea name="NameBox" placeholder = "Name" class="form-control">@display.UserComment</textarea>
       
    }

}

Output:

From Model:

Controller:

public IActionResult Index()
    {
        var dsplayModel = new DsplayModel();
        dsplayModel.UserComment = "This is some comment from Model";
        
        return View(dsplayModel);
    }

View:

@model DotNetWebApp.Models.DsplayModel

@using (Html.BeginForm("ControllerAction", "ControllerToPost", FormMethod.Post))
{
    @Html.TextAreaFor(model => model.UserComment)

}

Note: If you need list, just use foreach loop.

 <textarea class="form-control" rows="4">@Model.UserComment</textarea>

//Try 1
@foreach (DsplayModel display in @ViewBag.Controls)                                                         {
    <textarea id="txtArea" class="form-control mt-15" rows="3" 
    maxlength="500" 
   asp-for="UserComment">
    @display.UserComment
    </textarea>
}

//Try 2
@foreach (DsplayModel display in @ViewBag.Controls)                                                         {
   @Html.TextAreaFor(m => m.UserComment, new { id = "NameBox", placeholder = "Name", Value = @display.UserComment })
}
