I am attempting to implement an Update on a current text area value.

The datatype is set for multiline in my model

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

When the page loads for the textarea, it does not populate.

@Html.TextAreaFor(a => a.Text, new { @Value = Model.Text })

But for a textbox it does populate

@Html.TextBoxFor(a => a.Text, new { @Value = Model.Text })

Is there something I'm missing? this seems pretty straight forward.

it should work like this

  • no, that is not what I'm looking for, the Model.Text value needs to populate inside the textbox – walangala Mar 22 '18 at 19:47

  • Value should already be populated in the text area as if it was a placeholder, a user would be able to edit what is in the text area – walangala Mar 22 '18 at 19:56
  • Was taking a shot in the dark. Really would need to see more code. Definitely is helpful – Dylan Wright Mar 22 '18 at 20:03

@Html.TextAreaFor(m => m.UserName) should be enough - ASP MVC takes care of populate current value from model to textarea. Using { @Value = Model.Text } doesn't apply to textarea as it does not uses value attribute: How to add default value for html <textarea>?
