Silverlight——施工计划日报表（二）

Silverlight——施工计划日报表（一）

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"

    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; }

        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>

        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()

                InitializeComponent();

                } 
                #endregion
            }
            catch (Exception ex)
            {

        #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;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(4),EndDate=DateTime.Now.AddDays(15),Explain="实际时间"}
                }
            };
            _lstPlansData.Add(_planData2);
            PlansData _planData3 = new PlansData()

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。
