  What is the proper convention for using a NumericTextBox in an Editor Template. I have tried the standard ASP.NET MVC convention with an empty string for the name: 
  
  Html.Telerik().PercentTextBox().Name("").Value(Model)
  
  But I get the following exception:
  

  [ArgumentException: "value" cannot be null or empty.]
     Telerik.Web.Mvc.Infrastructure.Guard.IsNotNullOrEmpty(String parameter, String parameterName) +142
     Telerik.Web.Mvc.UI.ViewComponentBase.set_Name(String value) +21

  
  I can give the control a name like: Html.Telerik().PercentTextBox().Name("RateQuote_QualRate").Value(Model) but then the model binding only works for that particular field and it's not a true template.
  
  I'm using release 2011.2.712
  
  Thank you.

  Use a template similar to this:
  

  @model double

   

  @(Html.Telerik().NumericTextBox()

          .Name(ViewData.TemplateInfo.GetFullHtmlFieldName(string.Empty))

          .InputHtmlAttributes(new { style = "width:100%" })

          .Value(Model)

  )

  
  This gets the control name from ViewData.
  
  Kind regards
