1.自己怎么處理處理已渲染報表的保存和加載？

使用StiViewerControl類的靜態事件SavingDocument和LoadingDocument。SavingDocument用來保存已渲染的報表，LoadingDocument用來加載已渲染的報表。
保存已渲染的報表處理方法如下：

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.怎么實現在預覽窗口打印報表？

使用StiPreviewControl類的靜態事件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果。此外你還可以使用StiPreviewControl，它包含許多用來控制預覽窗口中控件可見性的屬性。你還可以在報表設計器里修改PreviewSettings屬性實現。 &nbsp;  

4.怎么關閉工具欄？

使用StiPreviewControl可以關閉工具欄，將ShowToolbar的屬性設置為false即可。

5.怎么指定報表生成器將結果輸出到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.怎么指定報表生成器使用我的預覽窗口？

你的報表預覽窗口需要有接收報表輸入對象的構造函數。然后使用報表類的PreviewForm屬性，該屬性有Type類型。換句話說你的報表預覽窗口將被第一個創建并顯示出來。

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中設置報表頁面的縮放？

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中設置報表頁面的預定義縮放？

使用縮放設置的預定義方法：

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.怎么從報表的代碼中將報表頁面加載到已渲染的報表中？

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.怎么在報表代碼中刷新報表預覽？

使用報表生成器的InvokeRefreshPreview方法：

C#

this.InvokeRefreshPreview();

VB

Me.InvokeRefreshPreview()

11.怎么訪問已渲染報表的頁面？

使用報表的RenderedPages屬性：

C#

foreach (StiPage page in report.RenderedPages)
{
}

VB

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

12.怎么在預覽中顯示所有組件而不打印它們？

使用Printable屬性：

• True-組件會顯示在設計器中并且會被打印
• False-組件會顯示在設計器中但是不會被打印

13.怎么在報表的代碼中給已渲染的報表添加或修改圖像？

創建或新增一個組件：

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)

如果報表已經從程序集中編譯或加載，替換圖像需要使用ImageToDraw屬性。    
修改報表中的圖像有兩種方法：
第一種-報表還沒被編譯
在報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換成代碼，然后報表回編譯且運行它。
第二種-報表從程序集中加載且編譯過
編譯報表

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.怎么在預覽窗口中只顯示被取消的按鈕而不顯示報表？

使用報表的IsStopped屬性：

C#

if (!report.IsStopped)

15.怎么附加渲染頁面的指示器？

使用報表的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，只有這樣才能運行Compile方法。
