SubreportObject 類別
代表置於報表中的子報表。子報表是出現在主報表中的一個獨立的或連結的報表。這個類別可以讓您擷取資訊並設定繼承自 ReportObject 類別的泛用格式選項,並且讓您將子報表開啟為 ReportDocument。
如需這個類型所有成員的清單,請參閱 SubreportObject 成員。
SubreportObject
[Visual Basic]
Public Class SubreportObject
Inherits ReportObject
[C#]
public class SubreportObject : ReportObject
[C++]
__gc public class SubreportObject : public ReportObject
[VJ#]
public class SubreportObject extends ReportObject
註解
透過 ReportObjects 集合的 Item 屬性依索引或名稱來擷取 ReportObject 物件,並將 ReportObject 轉換為 SubreportObject。
範例
下列範例會傳回 SubreportObject 物件。
[Visual Basic]
Private Function GetSubreportObject _
(ByVal reportObjectName As String) As SubreportObject
Dim subreport As SubreportObject
' 依名稱取得 ReportObject,將之轉換為 SubreportObject,
' 然後將它傳回來。
If TypeOf _
(Report.ReportDefinition.ReportObjects. _
Item(reportObjectName)) Is SubreportObject Then
subreport = _
Report.ReportDefinition.ReportObjects. _
Item(reportObjectName)
GetSubreportObject = subreport
Else : GetSubreportObject = Nothing
End If
End Function
[C#]
private SubreportObject GetSubreportObject
(string reportObjectName)
{
SubreportObject subreport;
// 依名稱取得 ReportObject,將之轉換為 SubreportObject,
// 然後將它傳回來。
subreport =
Report.ReportDefinition.ReportObjects[reportObjectName]
as SubreportObject;
if (subreport != null) return subreport;
else return null;
}
[C++]
SubreportObject* GetSubreportObject(String* reportObjectName)
{
SubreportObject* subreport;
// 依名稱取得 SubreportObject,將之轉換為 SubreportObject,
// 然後將它傳回來。
try
{
subreport = __try_cast<SubreportObject*>
(Report->ReportDefinition->
ReportObjects->Item[reportObjectName]);
return subreport;
}
catch(System::InvalidCastException*)
{
return 0;
}
};
[VJ#]
private SubreportObject GetSubreportObject
(String reportObjectName)
{
SubreportObject subreport;
// 依名稱取得 ReportObject,將之轉換為 SubreportObject,
// 然後將它傳回來。
subreport = (SubreportObject)
Report.get_ReportDefinition().get_ReportObjects().get_Item(reportObjectName);
if (subreport != null) return subreport;
else return null;
