Constructors

Report()

Initializes a new instance of the Report class with default settings.

Declaration
public Report()

Properties

Culture

Gets or sets the culture information associated with the report.

Declaration
public CultureInfo Culture { get; set; }
Property Value
System.Globalization.CultureInfo

A System.Globalization.CultureInfo representing the culture supported by the Report.

DataSource

Gets or sets the data source that the Report is displaying data for.

Declaration
public object DataSource { get; set; }
Property Value
System.Object

An object that functions as a data source.

Remarks

Telerik Reporting includes dedicated data source components that enable retrieving and feeding all data items from various sources. See all the available data source components at: https://docs.telerik.com/reporting/designing-reports/connecting-to-data/data-source-components/overview

For convenience, all the objects applicable to the DataSource property can be directly assigned to this DataSource property. At runtime, the report engine will wrap them in an ObjectDataSource to resolve the actual data.

DocumentName

Gets or sets a System.String representing the name of the report document.

Declaration
public string DocumentName { get; set; }
Property Value
System.String

A System.String representing the document name. The default value is the name of the Report this property belongs to.
Implements
Remarks

The value of this property is used to suggest a file name when exporting a report to one of the available export formats. This property value is not used when exporting from the standalone report designer. The report filename will be used instead.

Also used to specify the report name (root node) in the document map.

A System.String that starts with "=" is interpreted as an expression to evaluate the document name; otherwise it is interpreted as a literal string. The expression cannot contain any data fields.

Gets a GroupCollection that defines the groups for the Report

Declaration
public GroupCollection Groups { get; }
Property Value

Examples

This example illustrates how to set the caching of the report definition properties of a report.

var report1 = new Report1();

// Set the CacheDefinitionProperties to CacheDefinitionProperties.No to allow modifying the report definition at runtime.
// Please note that this approach might cause inpredictable behavior and will decrease the processing performance.
report1.ReportEngineSettings.CacheDefinitionProperties = Telerik.Reporting.CacheDefinitionProperties.No;

Dim report1 As New Report1()

'Set the CacheDefinitionProperties to CacheDefinitionProperties.No to allow modifying the report definition at runtime.
'Please note that this approach might cause inpredictable behavior And will decrease the processing performance.
report1.ReportEngineSettings.CacheDefinitionProperties = Telerik.Reporting.CacheDefinitionProperties.No

pdfSettings.Parameters.Add(new Telerik.Reporting.Parameter() { Name = "DocumentAuthor", Value = "YourName" });
report1.RuntimeSettings.Add(pdfSettings);

Dim pdfSettings = New Telerik.Reporting.RenderingSettings() With {

Methods

GetDataSources()

Gets all IDataSource instances available in the report definition, regardless if they are referenced by a data item or a report parameter.

Declaration
public IEnumerable<IDataSource> GetDataSources()
Returns
System.Collections.Generic.IEnumerable<IDataSource>

A read-only collection of IDataSource instances.

OnError(Object, ErrorEventArgs)

Declaration
protected virtual void OnError(object sender, ErrorEventArgs e)
Parameters
System.Object sender

ErrorEventArgs e

OnNeedDataSource(Object, EventArgs)

Declaration
protected virtual void OnNeedDataSource(object sender, EventArgs e)
Parameters
System.Object sender

System.EventArgs e

Events

Error

Declaration
public event ErrorEventHandler Error
Event Type
ErrorEventHandler

NeedDataSource

Occurs when the processing of the report processing instance (i.e., Report instance) begins and this instance has no DataSource property set.

Declaration
public event EventHandler NeedDataSource
Event Type
System.EventHandler

Remarks

The event is hooked on the definition Report instance, but the sender object in the event handler is the processing Report instance. The processing instance of the report inherits its DataSource from the definition instance, but if neither has DataSource set, this event is raised.

Examples

The following example demonstrates how to implement a NeedDataSource event handler:

void report_NeedDataSource(object sender, EventArgs e)
{
    Telerik.Reporting.Processing.Report processingReport = (Telerik.Reporting.Processing.Report)sender;
    object processingParameterValue = processingReport.Parameters["parameter1"].Value;
    processingReport.DataSource = GetData(processingParameterValue);
}

static object GetData(object value)
{
    // Implement your custom data retrieval logic instead
    return new string[] { "Sofia", "London", "Tokyo" };
}

Private Sub report_NeedDataSource(sender As Object, e As EventArgs)
    Dim processingReport As Telerik.Reporting.Processing.Report = DirectCast(sender, Telerik.Reporting.Processing.Report)
    Dim processingParameterValue As Object = processingReport.Parameters("parameter1").Value
    processingReport.DataSource = GetData(processingParameterValue)
End Sub

Private Shared Function GetData(value As Object) As Object
    ' Implement your custom data retrieval logic instead
    Return New String() {"Sofia", "London", "Tokyo"}
End Function
