1.自己怎么處理處理已渲染報(bào)表的保存和加載？

使用StiViewerControl類的靜態(tài)事件SavingDocument和LoadingDocument。SavingDocument用來(lái)保存已渲染的報(bào)表，LoadingDocument用來(lái)加載已渲染的報(bào)表。
保存已渲染的報(bào)表處理方法如下：

C#

private static void OnSavingDocument(object sender, EventArgs e)
{
StiReport report = sender as StiReport;
report.SaveDocument("MyFile.mdc");
}
StiViewerControl.SavingDocument += new EventHandler(OnSavingDocument);

VB

Private Shared Sub OnSavingDocument(ByVal sender As Object, ByVal e As EventArgs)
Dim Report As StiReport = TryCast(sender, StiReport)
Report.SaveDocument("MyFile.mdc")
End Sub
AddHandler StiViewerControl.SavingDocument, New EventHandler(AddressOf
Form1.OnSavingDocument)

加載已渲染報(bào)表的處理方法如下：

C#

private static void OnLoadingDocument(object sender, EventArgs e)
{
StiReport report = sender as StiReport;
report.LoadDocument("MyFile.mdc");
}
StiViewerControl.LoadingDocument += new EventHandler(OnLoadingDocument);

VB

Private Shared Sub OnLoadingDocument(ByVal sender As Object, ByVal e As EventArgs)
Dim Report As StiReport = TryCast(sender, StiReport)
Report.LoadDocument("MyFile.mdc")
End Sub
AddHandler StiViewerControl.LoadingDocument, New EventHandler(AddressOf
Form1.OnLoadingDocument)

2.怎么實(shí)現(xiàn)在預(yù)覽窗口打印報(bào)表？

使用StiPreviewControl類的靜態(tài)事件PrintingDocument。方法如下：

C#

private static void OnPrintingDocument(object sender, EventArgs e)
{
StiReport report = sender as StiReport;
report.Print();
}}
StiPreviewControl.PrintingDocument += new EventHandler(OnPrintingDocument);

VB

Private Shared Sub OnPrintingDocument(ByVal sender As Object, ByVal e As EventArgs)
Dim Report As StiReport = TryCast(sender, StiReport)
Report.Print()
End Sub
AddHandler StiPreviewControl.PrintingDocument, New EventHandler(AddressOf
Form1.OnPrintingDocument)

3.怎么去掉工具欄里的按鈕？

要想去掉預(yù)覽窗口中的按鈕，你需要修改StiPreviewConfig中的屬性。

C#

//Do this operation once when running the program
StiConfig.Load();
//Get service
StiPreviewConfigService config = StiConfig.Services.GetService(typeof(StiPreviewConfigService)) as
StiPreviewConfigService;
//Turn off all buttons of changes of the rendered report
config.PageNewEnabled = false;
config.PageDeleteEnabled = false;
config.PageDesignEnabled = false;
config.PageSizeEnabled = false;
//Save configuration if necessary
StiConfig.Save();

VB

'Do this operation once when running the program
StiConfig.Load()
'Get service
Dim Config As StiPreviewConfigService =
TryCast(StiConfig.Services.GetService(GetType(StiPreviewConfigService)), StiPreviewConfigService)
Disable all buttons of changes of a rendered report
Config.PageNewEnabled = False
Config.PageDeleteEnabled = False
Config.PageDesignEnabled = False
Config.PageSizeEnabled = False
'Save configuration if necessary
StiConfig.Save()

使用Configurator.exe也可以得到相同的結(jié)果。此外你還可以使用StiPreviewControl，它包含許多用來(lái)控制預(yù)覽窗口中控件可見性的屬性。你還可以在報(bào)表設(shè)計(jì)器里修改PreviewSettings屬性實(shí)現(xiàn)。 &nbsp;  

4.怎么關(guān)閉工具欄？

使用StiPreviewControl可以關(guān)閉工具欄，將ShowToolbar的屬性設(shè)置為false即可。

5.怎么指定報(bào)表生成器將結(jié)果輸出到StiPreviewControl中？

有兩種方法。第一種：

C#

StiReport report = new StiReport();
report.Load("MyReport.mrt");
report.Render();
myCustomPreview.Report = report;

VB

Dim Report As New StiReport
Report.Load("MyReport.mrt")
Report.Render()
MyCustomPreview.Report = Report

第二種：

C#

StiReport report = new StiReport();
report.PreviewControl = myCustomPreview;
report.Load("MyReport.mrt");
report.Show();

VB

Dim Report As New StiReport
Report.PreviewControl = MyCustomPreview
Report.Load("MyReport.mrt")
Report.Show()

6.怎么指定報(bào)表生成器使用我的預(yù)覽窗口？

你的報(bào)表預(yù)覽窗口需要有接收?qǐng)?bào)表輸入對(duì)象的構(gòu)造函數(shù)。然后使用報(bào)表類的PreviewForm屬性，該屬性有Type類型。換句話說(shuō)你的報(bào)表預(yù)覽窗口將被第一個(gè)創(chuàng)建并顯示出來(lái)。

C#

//Create a new window
public class Form1 : Form
{
public Form1(StiReport report)
{
}
}
//Fill the PreviewForm property
report.PreviewForm = typeof(Form1);

VB

'Create a new window
Public Class Form1
Inherits Form
Public Sub New(ByVal report As StiReport)
InitializeComponent()
End Sub
End Class
'Fill the PreviewForm property
Report1.PreviewForm = CType(GetType(Form1), Type)

7.怎么在StiPreviewControl中設(shè)置報(bào)表頁(yè)面的縮放？

使用SetZoom方法。示例：

C#

//Set zoom 100%
myPreviewControl.SetZoom(1);

VB

'Set zoom 100%
MyPreviewControl.SetZoom(1)  

8.怎么在StiPreviewControl中設(shè)置報(bào)表頁(yè)面的預(yù)定義縮放？

使用縮放設(shè)置的預(yù)定義方法：

C#

//Display the page
myPreviewControl.SetZoomOnePage();
//Display two pages
myPreviewControl.SetZoomTwoPages();
//Display multiple pages
myPreviewControl.SetZoomMultiplePages();
//Display a page. The page is to be aligned by the width in the StiPreviewControl
myPreviewControl.SetZoomPageWidth();

VB

'Display a page
MyPreviewControl.SetZoomOnePage()
'Display two pages
MyPreviewControl.SetZoomTwoPages()
'Display multiple pages
MyPreviewControl.SetZoomMultiplePages()
'Display a page. The page is to be aligned by the width in the StiPreviewControl
MyPreviewControl.SetZoomPageWidth()

9.怎么從報(bào)表的代碼中將報(bào)表頁(yè)面加載到已渲染的報(bào)表中？

C#

//Create a page
StiPage page = new StiPage();
//Load the page from a file
page.Load("MyPage.pg");
//Add a page to the collection of rendered pages
RenderedPages.Add(page);
//Refresh the window of preview
InvokeRefreshPreview();

VB

'Create a page
Dim Page As New StiPage
'Load the page from a file
Page.Load("MyPage.pg")
'Add a page to the collection of rendered pages
Report.RenderedPages.Add(Page)
'Refresh the window of preview
Report.InvokeRefreshPreview()

10.怎么在報(bào)表代碼中刷新報(bào)表預(yù)覽？

使用報(bào)表生成器的InvokeRefreshPreview方法：

C#

this.InvokeRefreshPreview();

VB

Me.InvokeRefreshPreview()

11.怎么訪問(wèn)已渲染報(bào)表的頁(yè)面？

使用報(bào)表的RenderedPages屬性：

C#

foreach (StiPage page in report.RenderedPages)
{
}

VB

Dim page As StiPage
For Each page In MyBase.RenderedPages
Next

12.怎么在預(yù)覽中顯示所有組件而不打印它們？

使用Printable屬性：

• True-組件會(huì)顯示在設(shè)計(jì)器中并且會(huì)被打印
• False-組件會(huì)顯示在設(shè)計(jì)器中但是不會(huì)被打印

13.怎么在報(bào)表的代碼中給已渲染的報(bào)表添加或修改圖像？

創(chuàng)建或新增一個(gè)組件：

C#

StiImage image = new StiImage();
image.Left = 0;
image.Top = 0;
image.Width = 10;
image.Height = 10;
//An image name should be unique in your report
image.Name = "MyUniqueName";
//Assign an image
image.Image = myImage;
//Add a component with an image with a report
report.Pages[0].Components.Add(image);

VB

Dim Image As StiImage = New StiImage()
Image.Left = 0
Image.Top = 0
Image.Width = 10
Image.Height = 10
'An image name should be unique in your report
Image.Name = "MyUniqueName"
'Assign an image
Image.Image = myImage
'Add a component with an image with a report
Report.Pages(0).Components.Add(Image)

如果報(bào)表已經(jīng)從程序集中編譯或加載，替換圖像需要使用ImageToDraw屬性。    
修改報(bào)表中的圖像有兩種方法：
第一種-報(bào)表還沒(méi)被編譯
在報(bào)表中找到包含圖像的組件：

C#

StiImage image = report.GetComponents()["image1"] as StiImage;

VB

Dim Image As StiImage = CType(Report.GetComponents()("image1"), StiImage)

修改圖像：

C#

image.Image = myImage;

VB

Image.Image = MyImage

這種方法，你的圖像你的圖像被轉(zhuǎn)換成代碼，然后報(bào)表回編譯且運(yùn)行它。
第二種-報(bào)表從程序集中加載且編譯過(guò)
編譯報(bào)表

C#

report.Compile();

VB

Report.Compile()

找到組件

C#

StiImage image = report.GetComponents()["image1"] as StiImage;

VB

Dim Image As StiImage = CType(Report.GetComponents()("image1"), StiImage)

指定圖像：

C#

image.ImageToDraw = myImage;

VB

Image.ImageToDraw = MyImage

14.怎么在預(yù)覽窗口中只顯示被取消的按鈕而不顯示報(bào)表？

使用報(bào)表的IsStopped屬性：

C#

if (!report.IsStopped)

15.怎么附加渲染頁(yè)面的指示器？

使用報(bào)表的Rendering事件。示例如下：

C#

//Create a new report
StiReport report = new StiReport();
report.Load("report.mrt");
//Compile this report by all means
report.Compile();
//Add to the Rendering event of a compiled report
report.CompiledReport.Rendering += new EventHandler(this.OnRendering);
//Start report rendering. Attention! The Render method is called from False arguments.
//This argument indicates that there is no need to show progress of report rendering
report.Render(false);
//Show the rendered report
report.Show();
//The event which we are attaching
private void OnRendering(object sender, EventArgs e)
{
StiReport report = sender as StiReport;
string info = (report.PageNumber -1).ToString();
}

VB

'Create a new report
Dim Report As New StiReport
Report.Load("report.mrt")
'Compile this report by all means
Report.Compile()
'Add to the Rendering event of a compiled report
AddHandler Report.CompiledReport.Rendering, New EventHandler(AddressOf Me.OnRendering)
'Start report rendering. Attention! The Render method is called from False arguments.
'This argument indicates that there is no need to show progress of report rendering
Report.Render(False)
'Show the rendered report
Report.Show()
'The event which we are attaching
Private Sub OnRendering(ByVal sender As Object, ByVal e As EventArgs)
Dim Report As StiReport = CType(sender, StiReport)
Dim Info As String = (Report.PageNumber -1).ToString()
End Sub

注意！你必須附加到report.CompiledReport，只有這樣才能運(yùn)行Compile方法。
