Silverlight——施工计划日报表（二）
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：

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：

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：

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。
