I need to schedule some tasks with ASP .NET and save a "Start date" and an "Interval", stored respectively as date (DateTime) and long (TimeSpan.Ticks) in my database.
Editing ticks values is not exactly what I define good UX, so I binded the proper MetaColumn, to the proper UIHint. After a few tests, I noticed how my GUI was - working, but not easy to understand as I was expecting.
I decided to deeply customize the FieldTemplateUserControl of Dynamic Data, to display and save multiple Columns I needed (Start Date, Start Time, Occours - Daily, Weekly, Monthly.., etc...). The solution is really simple, but there are few points you may need to bear in mind:
How to retrieve values (Schedule_EditField.ascx.cs)
protected override void OnDataBinding(EventArgs e)
DateTime? startFrom = (DateTime?)Eval("StartFrom");
long? timeIntervalTicks = (long?)Eval("TimeInterval");
DateTime? lastExecution = (DateTime?)Eval("LastExecution");
How to store values
protected override void ExtractValues(IOrderedDictionary dictionary)
dictionary["StartFrom"] = …; //logic here
dictionary["TimeInterval"] = …; //logic here
