近来一直在加班,基本上没有个人时间。所以更新不会很即时。
长话短说,先从界面代码开始吧。界面代码很简单,如下所示:
<UserControl xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk" xmlns:toolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit" x:Class="PlansView.ShowPlans" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:BubbleCremeTheme="System.Windows.Controls.Theming;assembly=System.Windows.Controls.Theming.BubbleCremeTheme" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400" Loaded="UserControl_Loaded"> <toolkit:BubbleCremeTheme> <StackPanel Name="stackPanel1" FlowDirection="LeftToRight" HorizontalAlignment="Left"> <StackPanel Orientation="Vertical"> <TextBlock Height="23" Name="txtTitle" HorizontalAlignment="Center" Text="标题" FontSize="18" FontWeight="Bold" Opacity="0.7" RenderTransformOrigin="0.5,0.5" > <TextBlock.RenderTransform> <CompositeTransform/> </TextBlock.RenderTransform> <TextBlock.Foreground> <LinearGradientBrush EndPoint="0.5,1" MappingMode="RelativeToBoundingBox" StartPoint="0.5,0"> <GradientStop Color="Black" Offset="1"/> <GradientStop Color="#FFE49C9C"/> </LinearGradientBrush> </TextBlock.Foreground> </TextBlock> <StackPanel Orientation="Horizontal" HorizontalAlignment="Right"> <Button Content="一键标记为完成" Name="btnFilishAll" Width="130" Margin="5,0,5,0" Click="btnFilishAll_Click" /> <Button Content="全屏" Name="BtnFullScreen" Width="100" Margin="5,0,5,0" Click="BtnFullScreen_Click" /> <Button Content="提交" Name="btnSubmit" Width="100" Click="Button_Click" Margin="5,0,5,0"/> </StackPanel> <ScrollViewer HorizontalContentAlignment="Left" HorizontalAlignment="Left" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" MaxHeight="513"> <ScrollViewer.BorderBrush> <LinearGradientBrush EndPoint="0.5,1.5" StartPoint="0.5,0"> <GradientStop Color="#FFE0E3BC"/> <GradientStop Color="#FF6C6C5C" Offset="1"/> </LinearGradientBrush> </ScrollViewer.BorderBrush> <Border BorderBrush="#FF333333" BorderThickness="2" Background="#FFC1C1C1" > <Grid x:Name="gdPlans" Background="#FFC1C1C1" MouseRightButtonDown="gdPlans_MouseRightButtonDown"> </Grid> </Border> </ScrollViewer> </StackPanel> </StackPanel> </toolkit:BubbleCremeTheme> </UserControl>
值得注意的是,这里用到了Silverlight 4.0工具包里面的BubbleCremeTheme主题。在使用的时候,注意引用,如“xmlns:BubbleCremeTheme="System.Windows.Controls.Theming;assembly=System.Windows.Controls.Theming.BubbleCremeTheme"”。然后需要注意的是,使用了ScrollViewer 实现滚动条,在ScrollViewer 里面放了一个Border 控件,用于绘制边框。在Border 控件里面,用到了Grid 控件。所有的数据都是基于Grid 控件生成的。
界面元素定义好了。接下来如下公共属性:
#region 公共属性 /// <summary> /// 日期格式(day、week、month) /// </summary> public string DateType { get; set; } /// <summary> /// 行号 /// </summary> public int RowIndex { get; set; } /// <summary> /// 开始时间 /// </summary> public DateTime StartDate { get; set; } /// <summary> /// 设置日期列数 /// </summary> public int DateColCount { get; set; } /// <summary> /// 文本列列数 /// </summary> public int NameColumns { get; set; } /// <summary> /// 计划列头 /// </summary> public string[] PlanHeads { get; set; } /// <summary> /// 日期列背景色 /// </summary> public Color DayBackGroundColor { get; set; } /// <summary> /// 数据 /// </summary> List<PlansData> LstPlansData { get; set; } /// <summary> /// 是否已经显示设置完成的提示 /// </summary> public bool HasShowSetFilishTip { get; set; } Dictionary<string, string> dicInitParams; //行背景(用于时间段) private static List<ImageBrush> RowBackGroundLst; private ImageBrush FilishImageBrush; /// <summary> /// 周的日数(默认7) /// </summary> int _weekDayCount; #endregion
属性定义好了,那么这些值是怎么传递过来的呢?使用的是InitParams。如下面代码:
public ShowPlans() { try { InitializeComponent(); SetInitialValue(); #region 设置显示的时间段 if (DateType == "day" && txtTitle.Text.Length > 0) { txtTitle.Text += string.Format("({0}~{1})", StartDate.ToShortDateString(), StartDate.AddDays(DateColCount).ToShortDateString()); } #endregion } catch (Exception ex) { MessageBox.Show("参数初始化出错:" + ex.Message, "错误", MessageBoxButton.OK); } } #region 参数初始化 /// <summary> /// 数据初始化 /// StartDate:开始日期,默认为当前时间 /// DateType:日期类型,可选值为(day、week、month),默认为day /// DateColCount:日期列数,day默认为30,week默认为10,month默认为12 /// Title:标题 /// PlanHeads:文字标头,多列需用“;”分隔。值需用Url编码。 /// Data:数据。格式为Json,需用Url编码。映射的类为PlansData。 /// DayBackGroundColor:日期列背景色 /// WeekDayCount:周涵盖的天数(默认7) /// OnlyResponseHasEdit:仅仅只输出编辑项 /// </summary> private void SetInitialValue() { RowIndex = 0; #region 设置默认值 StartDate = DateTime.Now; DateColCount = 30; DateType = "day"; NameColumns = 1; DayBackGroundColor = Colors.White; HasShowSetFilishTip = false; #region 图片画刷 RowBackGroundLst = new List<ImageBrush>() { new ImageBrush() { ImageSource=new BitmapImage(new Uri("plink.png", UriKind.Relative)) }, new ImageBrush() { ImageSource=new BitmapImage(new Uri("blue.png", UriKind.Relative)) }, new ImageBrush() { ImageSource=new BitmapImage(new Uri("red.png", UriKind.Relative)) }, new ImageBrush() { ImageSource=new BitmapImage(new Uri("green.png", UriKind.Relative)) }, }; FilishImageBrush = new ImageBrush() { ImageSource = new BitmapImage(new Uri("red.png", UriKind.Relative)) }; #endregion #endregion #region 设置初始化参数 dicInitParams = App.Current.Host.InitParams as Dictionary<string, string>; if (dicInitParams != null && dicInitParams.Count > 0) { //标题 if (dicInitParams.ContainsKey("Title")) txtTitle.Text = dicInitParams["Title"] ?? string.Empty; else txtTitle.Visibility = Visibility.Collapsed; //设置开始日期 if (dicInitParams.ContainsKey("StartDate")) StartDate = Convert.ToDateTime(dicInitParams["StartDate"]); //周涵盖天数(仅当DateType=week时启用) _weekDayCount = 7; //日期列背景色 if (dicInitParams.ContainsKey("DayBackGroundColor")) DayBackGroundColor = ReturnColorFromString(dicInitParams["DayBackGroundColor"]); //日期类型 if (dicInitParams.ContainsKey("DateType")) { DateType = dicInitParams["DateType"]; if (DateType == "week") { if (!dicInitParams.ContainsKey("DateColCount")) { DateColCount = 10; } if (dicInitParams.ContainsKey("WeekDayCount")) { _weekDayCount = Convert.ToInt32(dicInitParams["WeekDayCount"]); } } else if (DateType == "month") { if (!dicInitParams.ContainsKey("DateColCount")) { DateColCount = 12; } } } //日期列列数 if (dicInitParams.ContainsKey("DateColCount")) DateColCount = Convert.ToInt32(dicInitParams["DateColCount"]); //文本列列头 if (dicInitParams.ContainsKey("PlanHeads")) { PlanHeads = HttpUtility.UrlDecode(dicInitParams["PlanHeads"]).Split(';'); NameColumns = PlanHeads.Length; } #endregion } else { MessageBox.Show("启动参数未设置"); } } #endregion
参数设置好了,但是数据还没有呢?在上一篇——《Silverlight——施工计划日报表(一)》中介绍过数据类了。首先在Silverlight项目中定义PlansData类,具体属性如下:
using System; using System.Collections.Generic; namespace PlansView { /// <summary> /// 数据 /// </summary> public class PlansData { public List<Plan> LstPlan { get; set; } /// <summary> /// 计划时间集合 /// </summary> public List<PlanDate> LstPlanDate { get; set; } } /// <summary> /// 计划 /// </summary> public class Plan { /// <summary> /// 计划名称 /// </summary> public string PlanName { get; set; } } /// <summary> /// 计划日期 /// </summary> public class PlanDate { /// <summary> /// 说明 /// </summary> public string Explain { get; set; } /// <summary> /// 开始时间 /// </summary> public DateTime? StartDate { get; set; } /// <summary> /// 结束时间 /// </summary> public DateTime? EndDate { get; set; } /// <summary> /// 允许的最小值 /// </summary> public DateTime? MinDate { get; set; } /// <summary> /// 允许的最大值 /// </summary> public DateTime? MaxDate { get; set; } /// <summary> /// 是否只读 /// </summary> public bool IsReadOnly { get; set; } /// <summary> /// 是否允许超过当前时间 /// </summary> public bool CanGreaterThanNow { get; set; } /// <summary> /// 是否已编辑 /// </summary> public bool HasEdit { get; set; } /// <summary> /// 是否已完成 /// </summary> public bool IsFlish { get; set; } /// <summary> /// 是否允许撤销 /// </summary> public bool AllowCancel { get; set; } /// <summary> /// 是否允许为空(必填情况下,无法提交数据) /// </summary> public bool AllowBlank { get; set; } /// <summary> /// 自定义标记 /// </summary> public string Tag { get; set; } } }
这个类是用来控制数据行的。开始时间和结束时间控制显示的条状的长度。接下来,需要使用JSON.NET组件(http://james.newtonking.com/projects/json-net.aspx)。
下载好该组件后,引用Json.Silverlight(Silverlight的JSON组件用起来不方便)。这样我们就可以很方便的将JSON字符串反序列化成对象了,也可以将对象序列化成JSON字符串。于是,只需要在InitParams传入JSON字符串,然后反序列话即可。如下所示:
#region 设置数据 private void LoadData() { if (dicInitParams != null && dicInitParams.ContainsKey("Data")) LstPlansData = JsonConvert.DeserializeObject<List<PlansData>>(HttpUtility.UrlDecode(dicInitParams["Data"])); } #endregion
那么InitParams如何设置呢,测试页(.aspx页面)页面元素如下:
<form id="form1" runat="server" style="height:100%"> <div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <param name="source" value="ClientBin/PlansView.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="4.0.50826.0" /> <param name="autoUpgrade" value="true" /> <param name="initParams" value='<%=InitParams %>' /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50826.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="获取 Microsoft Silverlight" style="border-style:none"/> </a> </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div> </form>
在后来代码中,InitParams 如此定义:
public string InitParams { get; set; } protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { try { InitParams = "Title=施工计划,DateColCount=80,PlanHeads=工程名称,Data="; List<PlansData> _lstPlansData = new List<PlansData>(); LoadData(_lstPlansData); InitParams += HttpUtility.UrlEncode(JsonConvert.SerializeObject(_lstPlansData, Formatting.Indented)); //LogManager.WriteTraceLog(JsonConvert.SerializeObject(_lstPlansData, Formatting.Indented)); } catch (Exception ex) { LogManager.WriteErrorLog(ex); } } } private static void LoadData(List<PlansData> _lstPlansData) { PlansData _planData1 = new PlansData() { LstPlan = new List<Plan>() { new Plan(){PlanName="木工轻钢割断墙"} }, LstPlanDate = new List<PlanDate>() { new PlanDate(){StartDate=DateTime.Now,EndDate=DateTime.Now.AddDays(3),Explain="基准时间",IsReadOnly=true}, new PlanDate(){StartDate=DateTime.Now.AddDays(1),EndDate=DateTime.Now.AddDays(4),Explain="计划时间",CanGreaterThanNow=true}, new PlanDate(){StartDate=DateTime.Now.AddDays(2),EndDate=DateTime.Now.AddDays(5),Explain="实际时间",IsFlish=true,AllowBlank=false} } }; _lstPlansData.Add(_planData1); PlansData _planData2 = new PlansData() { LstPlan = new List<Plan>() { new Plan(){PlanName="贴文化石,刷漆"} }, LstPlanDate = new List<PlanDate>() { new PlanDate(){StartDate=DateTime.Now.AddDays(5),EndDate=DateTime.Now.AddDays(16),Explain="计划时间",CanGreaterThanNow=true}, new PlanDate(){StartDate=DateTime.Now.AddDays(4),EndDate=DateTime.Now.AddDays(15),Explain="实际时间"} } }; _lstPlansData.Add(_planData2); PlansData _planData3 = new PlansData() { LstPlan = new List<Plan>() { new Plan(){PlanName="石膏板吊棚"} }, LstPlanDate = new List<PlanDate>() { new PlanDate(){StartDate=DateTime.Now.AddDays(5),EndDate=DateTime.Now.AddDays(18),Explain="基准时间",IsReadOnly=true,CanGreaterThanNow=true}, new PlanDate(){StartDate=DateTime.Now.AddDays(8),EndDate=DateTime.Now.AddDays(12),Explain="计划时间"}, } }; _lstPlansData.Add(_planData3); PlansData _planData4 = new PlansData() { LstPlan = new List<Plan>() { new Plan(){PlanName="大白乳胶漆"} }, LstPlanDate = new List<PlanDate>() { new PlanDate(){StartDate=DateTime.Now.AddDays(15),EndDate=DateTime.Now.AddDays(18),Explain="基准时间",IsReadOnly=true}, new PlanDate(){StartDate=DateTime.Now.AddDays(19),EndDate=DateTime.Now.AddDays(25),Explain="计划时间"}, new PlanDate(){StartDate=DateTime.Now,EndDate=DateTime.Now.AddDays(5),Explain="实际时间"} } }; _lstPlansData.Add(_planData4); PlansData _planData5 = new PlansData() { LstPlan = new List<Plan>() { new Plan(){PlanName="铺地板"} }, LstPlanDate = new List<PlanDate>() { new PlanDate(){StartDate=DateTime.Now.AddDays(3),EndDate=DateTime.Now.AddDays(5),Explain="基准时间"}, new PlanDate(){StartDate=DateTime.Now.AddDays(6),EndDate=DateTime.Now.AddDays(15),Explain="计划时间"}, new PlanDate(){StartDate=DateTime.Now.AddDays(7),EndDate=DateTime.Now.AddDays(19),Explain="实际时间"} } }; _lstPlansData.Add(_planData5); PlansData _planData6 = new PlansData() { LstPlan = new List<Plan>() { new Plan(){PlanName="测试1"} }, LstPlanDate = new List<PlanDate>() { new PlanDate(){StartDate=DateTime.Now,EndDate=DateTime.Now,Explain="基准时间"}, new PlanDate(){StartDate=DateTime.Now.AddDays(6),EndDate=DateTime.Now.AddDays(15),Explain="计划时间"}, new PlanDate(){StartDate=DateTime.Now.AddDays(79),EndDate=DateTime.Now.AddDays(79),Explain="实际时间"} } }; _lstPlansData.Add(_planData6);
}
先写到这里吧。本文是按初学者的角度来写的,如果你是老手,那么有些内容就可以直接略过了,如果有不当之处,请指教;
如果你是初学者,还有不明白的,那么可以说明。
Silverlight我也只是入门而已,一直在加班,从未停歇过。仅仅只是地铁上看完了风云的书,然后花3天时间做了这个,待完善处还很多。
希望此文能够对大家有所帮助。
有时间我会继续写完的。
