Use ToString () with @ Html.DisplayFor

Question

Why can't I use ToString ("#. ##") with @ Html.DisplayFor, for example:

@Html.DisplayFor(modelItem => modelItem.Balance.ToString("#.##")) 

Answer 1

when I came across this before, I just added Getter to the model that View uses.

 public string FormattedBalance { get { return this.Balance.ToString("#.##"); } } 

And then just use it in your view:

 @Html.DisplayFor(ModelItem => ModelItem.FormattedBalance) 

Answer 2

DisplayFor displays the default ToString method for the specified model property.

You can achieve what you want by writing your own @helper.
