1.如何加載和保存報表？

加載報表：

C#

StiReport report = new StiReport();
report.Load("report.mrt");

VB

Dim Report As StiReport = New StiReport()
Report.Load("report.mrt")

保存報表：

C#

StiReport report = new StiReport();
report.Save("report.mrt");

VB

Dim Report As StiReport = New StiReport()
Report.Save("report.mrt")

2.如何渲染報表？

下面的代碼實現(xiàn)報表的渲染并且將報表顯示在預(yù)覽查看其中：

C#

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

VB

Dim Report As StiReport = New StiReport()
Report.Load("report.mrt")
Report.Show()

3.如何給報表綁定數(shù)據(jù)？

要將數(shù)據(jù)綁定到一個報表，你必須使用RegData方法注冊報表的DataStore數(shù)據(jù)。填充數(shù)據(jù)集作為傳遞參數(shù)的方法是相同的。例如，從XML加載數(shù)據(jù)：

C#

DataSet dataSet1 = new DataSet();
ddataSet1.ReadXmlSchema("Demo.xsd");
dataSet1.ReadXml("Demo.xml");
StiReport report = new StiReport();
report.RegData("MyDataSet",dataSet1);

VB

Dim Data As DataSet = New DataSet()
Data.ReadXmlSchema("Demo.xsd")
Data.ReadXml("Demo.xml")
Dim Report As StiReport New StiReport()
Report.RegData("MyDataSet",Data)

4.應(yīng)該在加載報表前還是加載后附加數(shù)據(jù)？

都可以。示例如下：
示例1：

C#

StiReport report = new StiReport();
report.Load("MyReport.mrt");
report.RegData("MyDataSet",dataSet1);

VB

Dim Report As StiReport = New StiReport()
Report.Load("MyReport.mrt")
Report.RegData("MyDataSet",DataSet1)

示例2：

C#

StiReport report = new StiReport();
report.RegData("MyDataSet",dataSet1);
report.Load("MyReport.mrt");

VB

Dim Report As StiReport = New StiReport()
Report.RegData("MyDataSet",DataSet1)
Report.Load("MyReport.mrt")  

兩個示例都是一樣的。

5.如何運行報表設(shè)計器？

運行報表設(shè)計器有兩種方法。首先，你可以使用報表對象的Design方法：

C#

StiReport report = new StiReport();
report.Design();

VB

Dim Report As StiReport = New StiReport()
Report.Design()

然后，你可以使用設(shè)計器自身的Show方法：

C#

Stimulsoft.Report.Design.StiDesigner designer = new
Stimulsoft.Report.Design.StiDesigner();
designer.Show();

VB

Dim Designer As Stimulsoft.Report.Design.StiDesigner = New
Stimulsoft.Report.Designer.StiDesigner()
Designer.Show()

6.如何保存和加載渲染后的報表？

保存渲染后的報表：

C#

//渲染報表
StiReport report = new StiReport();
report.Load("report.mrt");
report.Render();
//保存報表
report.SaveDocument("document.mdc"));

VB

'渲染報表
Dim Report As StiReport = New StiReport()
Report.Load("report.mrt")
Report.Render()
'保存報表
Report.SaveDocument("document.mdc"))

加載以保存的渲染后的報表：

C#

StiReport report = new StiReport();
report.LoadDocument("document.mdc");

VB

Dim Report As StiReport = New StiReport()
Report.LoadDocument("document.mdc")

7.如何加載DataSet XSD Schema？

要加載DataSet XSD模式，你需要使用ImportXMLSchema方法：

C#

StiReport report = new StiReport();
DataSet dataSet = new DataSet("Test");
dataSet.ReadXmlSchema("dataset.xsd");
report.Dictionary.ImportXMLSchema(dataSet);

VB

Dim Report As StiReport = New StiReport()
Dim Data As DataSet = New DataSet("Test")
Data.ReadXmlSchema("dataset.xsd")
Report.Dictionary.ImportXMLSchema(Data)

DataSet XSD模式僅在設(shè)計器中需要。

8.如何修改報表的腳本語言？

使用報表StiReport類的Language屬性來修改報表的當(dāng)前腳本語言。示例：

C#

//將當(dāng)前腳本語言修改為VB
StiReport report = new StiReport();
report.ScriptLanguage = StiReportLanguageType.VB;
//生成新的報表
report.ScriptNew();

VB

'將當(dāng)前腳本語言修改為VB
Dim Report As StiReport = New StiReport()
Report.ScriptLanguage = StiReportLanguageType.VB
'生成一個新報表
Report.ScriptNew()
