Editing a grid with a PercentTextBox doesn't save empty values.

[Makoto]

I have a grid, and one of the columns is a percent value.  In my view model, I am specifying that it should use my custom percent editor control:

[UIHint("Percent")]
public decimal? PercentObligation { get; set; }

And the Percent control looks like this:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Nullable<double>>" %>
<%= Html.Telerik().PercentTextBox()
        .Name(ViewData.TemplateInfo.GetFullHtmlFieldName(string.Empty))
        .InputHtmlAttributes(new { style = "width:100%" })
        .MaxValue(100)
        .MinValue(0)
        .DecimalDigits(4)
        .Spinners(false)
        .Value(Model)
%>

This actually works just fine and I'm able to show the percent control and change values and save them just fine.  However, the problem is when I don't have a value. 

I was looking at the POST variables when I save changes to my grid and noticed that it only POSTs the "PercentObligation" field only if there is a value in there.  If there is no value, then that field is never sent in the POST.  I would expect it to post that field without a value, but it doesn't. 

Since I am using MVC's built-in UpdateModel() method, it doesn't properly update my model since it didn't receive a new value for PercentObligation.

Is this a known bug?

Yes this is happening to me to. To me this is a bug, but these Telerik number controls do not really support Nullable values which is a shame.

My workaround is to check Request.Form for the property (or your model if you have it in your Update(MyModel model) action) after the call to Update, if it is null you know you can then update the db object to null.

It's happening the same thing to me too.

Does it has a workaround?

So... 

Someone has a solution?
