XAF TimeSpan Editor
Here's a simple solution for entering TimeSpan data in a casual style : " 1 day 39 hours 78 min"https://lh5.googleusercontent.com/-lNas0ipAp8E/TW7evdvlleI/AAAAAAABXOY/aLaPt0Q4kLQ/s640/TimeSpan.png
The Solutions is to create a prpoperty editor that hosts simple Text editor, with some custom logic undeneath, that parses the string and converts it to TimeSpan after entering the string. And also Convert the timespan form the database to string, to be displayed in the casual format.
using System;using System.Text.RegularExpressions;using DevExpress.ExpressApp.Editors;using DevExpress.ExpressApp.Model;using DevExpress.ExpressApp.Win.Editors;using DevExpress.XtraEditors.Mask;using DevExpress.XtraEditors.Repository; namespace Solution2.Module.Win{ [PropertyEditor(typeof(TimeSpan))] public class DurationPropertyEditor : DXPropertyEditor { public DurationPropertyEditor(Type objectType, IModelMemberViewItem model) : base(objectType, model) { } protected override object CreateControlCore() { return new StringEdit(); } protected override void SetupRepositoryItem(RepositoryItem item) { base.SetupRepositoryItem(item); ((RepositoryItemStringEdit)item).Mask.MaskType = MaskType.RegEx; ((RepositoryItemStringEdit)item).Mask.EditMask = @"\s*((\d?\d?\d?\s*(d(ays?)?)))?\s*((\d?\d?\s*(h(ours)?)?))?\s*(\d?\d?\s*(m(in(utes)?)?)?)?"; if (Control == null) return; Control.ShowToolTips = true; Control.ToolTip = " Examples:" + Environment.NewLine + " 1d = 1 Day" + Environment.NewLine + " 1 day = 1 Day" + Environment.NewLine + " 2d 5h 45 m = 2 Days 5 Hours 45 minutes" + Environment.NewLine + " 2 days 4 hours 25 min= 2 Days 4 Hours 25 minutes" + Environment.NewLine; Control.EditValueChanged += Control_EditValueChanged; } void Control_EditValueChanged(object sender, EventArgs e) { WriteValue(); OnControlValueChanged(); } protected override object GetControlValueCore() { return ParseTimeSpan(Control.Text); } protected override void ReadValueCore() { Control.EditValue = DecodeTimeSpan((TimeSpan) PropertyValue); } public static TimeSpan ParseTimeSpan(string s) { const string Quantity = "quantity"; const string Unit = "unit"; const string Days = @"(d(ays?)?)"; const string Hours = @"(h((ours?)|(rs?))?)"; const string Minutes = @"(m((inutes?)|(ins?))?)"; const string Seconds = @"(s((econds?)|(ecs?))?)"; var timeSpanRegex = new Regex( string.Format(@"\s*(?<{0}>\d+)\s*(?<{1}>({2}|{3}|{4}|{5}|\Z))", Quantity, Unit, Days, Hours, Minutes, Seconds), RegexOptions.IgnoreCase); var matches = timeSpanRegex.Matches(s); var ts = new TimeSpan(); foreach (Match match in matches) { if (Regex.IsMatch(match.Groups.Value, @"\A" + Days)) { ts = ts.Add(TimeSpan.FromDays(double.Parse(match.Groups.Value))); } else if (Regex.IsMatch(match.Groups.Value, Hours)) { ts = ts.Add(TimeSpan.FromHours(double.Parse(match.Groups.Value))); } else if (Regex.IsMatch(match.Groups.Value, Minutes)) { ts = ts.Add(TimeSpan.FromMinutes(double.Parse(match.Groups.Value))); } else if (Regex.IsMatch(match.Groups.Value, Seconds)) { ts = ts.Add(TimeSpan.FromSeconds(double.Parse(match.Groups.Value))); } else { // Quantity given but no unit, default to Hours ts = ts.Add(TimeSpan.FromHours(double.Parse(match.Groups.Value))); } } return ts; } public static string DecodeTimeSpan(TimeSpan timeSpan) { var time = string.Empty; if (timeSpan.Days > 0) time = timeSpan.Days + " Days"; if (timeSpan.Hours > 0) time += (time != string.Empty ? " " : "") + timeSpan.Hours + " Hours"; if (timeSpan.Minutes > 0) time += (time != string.Empty ? " " : "") + timeSpan.Minutes + " Minutes"; return time; } }}
大侠，看起来很费劲。能否作为附件传上来？ nickcole 发表于 2016-8-11 14:45
