DataProviderCollection Class

In This Topic

This data provider can be used to combine multiple other data providers into one datasource. Use it if you have e.g. multiple DataSet classes from where to pull data or if you would like to have a mix of XML and custom object data.

'Declaration
 
Public NotInheritable Class DataProviderCollection 
   Implements ICanHandleUsedIdentifiers, ICanHandleUsedRelations, ICrossRelationProvider, IDataProvider, IRequireCollectedReportParameters

public sealed class DataProviderCollection : ICanHandleUsedIdentifiers, ICanHandleUsedRelations, ICrossRelationProvider, IDataProvider, IRequireCollectedReportParameters

public ref class DataProviderCollection sealed : public ICanHandleUsedIdentifiers, ICanHandleUsedRelations, ICrossRelationProvider, IDataProvider, IRequireCollectedReportParameters

Remarks

It must be ensured that the table names within the collection of registered data sources are unique and therefore do not exist more than once under the same name.

Example

DataSet ds1 = CreateDataSet();
DataSet ds2 = CreateOtherDataSet();

// combine the data from ds1 and ds2 into one datasource
DataProviderCollection providerCollection = new DataProviderCollection();
providerCollection.Add(new AdoDataProvider(ds1));
providerCollection.Add(new AdoDataProvider(ds2));
LL.DataSource = providerCollection;
LL.Design();

VB.NET

Dim ds1 As DataSet = CreateDataSet()
Dim ds2 As DataSet = CreateOtherDataSet()

' combine the data from ds1 and ds2 into one datasource
Dim providerCollection As New DataProviderCollection()
providerCollection.Add(New AdoDataProvider(ds1))
providerCollection.Add(New AdoDataProvider(ds2))
LL.DataSource = providerCollection
LL.Design()
