Editable Grid Removes Milliseconds from DateTime Fields

Environment

Product

Progress® Telerik® UI Grid for ASP.NET MVC

Description

When editing a Kendo UI Grid for ASP.NET MVC, the model that is sent to the server upon clicking Update has the milliseconds reset to zero for date fields which previously had their milliseconds set to a non-zero value.

Steps to Reproduce

1. Bind a Grid column to a DateTime field which has milliseconds explicitly set to a value different from zero.
2. Edit the Grid and save the changes.

The DateTime values are sent to the server with their milliseconds reset to zero even when the given field was not edited.

Cause

The date objects are serialized by using a "g" (general) date format that does not include the milliseconds value.

Solution

Before the request is sent to the server, override the default date serialization by adding a Data function to the configuration of the Update DataSource request. There, you can process dates before they are sent out.

    .Update(update => update.Action("Products_Update", "Grid").Data("serializeDates"))

    function serializeDates(data) {
        for (var field in data) {
            if (data[field] instanceof Date) {
                data[field] = kendo.toString(data[field], "yyyy-MM-ddTHH:mm:ss.fffZ");
            }
        }
    }
