Silverlight——施工计划日报表（二）

2023-08-07 11:16:28

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：

}

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。
