Stimulsoft Reports.WinRT中的ViewerRT用于在WinRT中顯示報表、縮放、保存、打印報表的控件。本文將展示如何加載和保存報表的代碼。

顯示報表

　　添加以下代碼便可以顯示已經(jīng)渲染好的報表（*.mdc, *.mdz, *.mdx）。

XAML文件：

<Page x:Class="Demo.RT.BlankPage"
xmlns="//schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="//schemas.microsoft.com/winfx/2006/xaml"
xmlns:viewerRT="using:Stimulsoft.Report.Viewer.RT">
<viewerRT:StiViewerControl x:Name="viewerControl"/>
</Page>

CS文件：

namespace Demo.RT
{
public sealed partial class BlankPage : Page
    {
        #region Handlers
        async private void BlankPage_Loaded(object sender, RoutedEventArgs
e)
        {
            StorageFolder folder = Windows.Storage.KnownFolders.
DocumentsLibrary;
            StorageFile storageFile = await folder.GetFileAsync(
"SimpleList.mdc");
            StiReport report = new StiReport();
            await report.LoadDocumentAsync(storageFile);
            viewerControl.Report = report;
        }
        #endregion
        public BlankPage()
        {
            this.InitializeComponent();
            this.Loaded += BlankPage_Loaded;
        }
    }
}

　　以下代碼用于顯示報表模板，即還未渲染的報表(*.mrt, *.mrz, *.mrx)。

XAML文件：

<Page x:Class="Demo.RT.BlankPage"
xmlns="//schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="//schemas.microsoft.com/winfx/2006/xaml"
xmlns:viewerRT="using:Stimulsoft.Report.Viewer.RT">
<viewerRT:StiViewerControl x:Name="viewerControl"/>
</Page>

CS文件：

namespace Demo.RT
{
public sealed partial class BlankPage : Page
{
#region Handlers
async private void BlankPage_Loaded(object sender,
RoutedEventArgs e)
{
StorageFolder folder = Windows.Storage.KnownFolders.
DocumentsLibrary;
StorageFile storageFile = await folder.GetFileAsync
("SimpleList.mrt");
StiReport report = new StiReport();
await report.LoadAsync(storageFile);
await report.RenderAsync();
viewerControl.Report = report;
}
#endregion
public BlankPage()
{
this.InitializeComponent();
this.Loaded += BlankPage_Loaded;
}
}
}

　　接下來可以通過點(diǎn)擊“打開”按鈕打開已渲染的報表。

保存報表

　　下面是保存報表的代碼示例。

XAML文件：

<Page x:Class="Demo.RT.BlankPage"
xmlns="//schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="//schemas.microsoft.com/winfx/2006/xaml"
xmlns:viewerRT="using:Stimulsoft.Report.Viewer.RT">
<viewerRT:StiViewerControl x:Name="viewerControl"/>
</Page>

CS文件：

namespace Demo.RT
{
public sealed partial class BlankPage : Page
{
#region Handlers
async private void buttonSaveReport_Click(object sender,
RoutedEventArgs e)
         {
StiReport report = new StiReport();
StorageFolder folder = Windows.Storage.KnownFolders.
DocumentsLibrary;
StorageFile storageFile = await folder.CreateFileAsync
("Report1.mdc");
await report.SaveDocumentAsync(storageFile);
         }
#endregion
public BlankPage()
{
this.InitializeComponent();
this.Loaded += BlankPage_Loaded;
}
}
}
