Time parameters

[Titus]

I want to use time parameters (like start time, end time, etc). I used TimeSpan, which works well, except for one thing. The parameter values are not saved between sessions.

I am using something like this:

        [Description("Start Time")]
        [GridCategory("Time Interval")]
        public TimeSpan StartTime
        {
            get { return strtTm; }
            set { strtTm = value; }
        }

What am I doing wrong? How can I get the values saved between sessions?

Hello Titus,

Thanks for the note.

The TimeSpan object needs to be serialized so it can be saved to an XML document. Changing the property like so allows saving to the workspace:

 
        private TimeSpan strtTm;
        ...   
        [XmlIgnore]
        [Description("Start Time")]
        [GridCategory("Time Interval")]
        public TimeSpan StartTime
        {
            get { return strtTm; }
            set { strtTm = value; }
        }

        [Browsable(false)]
        [XmlElement(DataType="duration", ElementName="StartTime")]
        public string StartTimeString
        {
            get 
            { 
                return XmlConvert.ToString(StartTime); 
            }
            set 
            { 
                StartTime = string.IsNullOrEmpty(value) ?
                    TimeSpan.Zero : XmlConvert.ToTimeSpan(value); 
            }
        }

Please let me know if I can assist further.

Thank you, Chris, it did the trick.

One thing though, for anyone else who might need this.
using System.Xml; has to be added to #region Using declarations for XmlConvert to work.
