Answer 1

I would use editor templates in my views. I would define view models which are specifically tailored to the requirements of the given view (in this case limiting it to 2 decimals):

[DisplayFormat(DataFormatString = "{0:n2}", ApplyFormatInEditMode = true)]
public decimal Viewers{ get; set; }

or You can simply use regular expression with model like

[RegularExpression(@"^\d+.\d{0,2}$")]
public decimal Viewers{ get; set; }

and then in html:

@Html.EditorFor(m => m.Viewers) 

or TextBoxFor()will also work with regular expression

@Html.TextBoxFor(m => m.Viewers, new { @tabindex = 7 })
