XRSummary.Running Property

Gets or sets a value specifying a report area, for which the arithmetic function is calculated.

Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v24.1.dll

NuGet Package: DevExpress.Reporting.Core

Declaration

C#

[DefaultValue(SummaryRunning.None)]
public virtual SummaryRunning Running { get; set; }

VB.NET

<DefaultValue(SummaryRunning.None)>
Public Overridable Property Running As SummaryRunning

Property Value

Type	Default	Description
SummaryRunning	None	A SummaryRunning enumeration value.

Available values:

Name	Description
None	The function is not calculated.
Group	The function is calculated for every group.
Report	The function is calculated for the entire report.
Page	The function is calculated for every page.

Remarks

The set of possible values for this property is available at SummaryRunning, and the arithmetic function to be calculated is set by the XRSummary.Func property.

If this property is set to the SummaryRunning.Report, a label always displays the function value calculated for the entire report.

If this property is set to the SummaryRunning.Page, a label always displays the function value calculated for the current page where the label is printed.

If this property is set to the SummaryRunning.Group, the displayed result depends on the band where the label is positioned:

• GroupHeaderBand, GroupFooterBand or DetailBand - the label displays the function value calculated for the current group;
• any other band - the label displays “None”.

Example

The following example demonstrates how to set summary options for a label at runtime. The method below creates an XRSummary object, sets its properties, and sets the XRLabel.Summary property. This example assumes that there is an already existing XRLabel object, passed as a parameter and bound to a dataset field that contains a numerical value.

C#

using DevExpress.XtraReports.UI;
// ...
public void SetFunction(XRLabel label) {
    // Create an XRSummary object. 
    XRSummary summary = new XRSummary();

    // Set a function which should be calculated. 
    summary.Func = SummaryFunc.Avg;

    // Set a range for which the function should be calculated. 
    summary.Running = SummaryRunning.Group;

    // Set the "ingore null values" option. 
    summary.IgnoreNullValues = true;

    // Set the "treat strings as numerics" option.
    summary.TreatStringsAsNumerics = true;

    // Set the output string format. 
    summary.FormatString = "{0:c2}";

    // Make the label calculate the specified function for the 
    // value specified by its DataBindings.Text property. 
    label.Summary = summary;
}

VB.NET

Imports DevExpress.XtraReports.UI
' ...
Public Sub SetFunction(ByVal label As XRLabel)
    ' Create an XRSummary object. 
    Dim summary As New XRSummary()

    ' Set a function which should be calculated. 
    summary.Func = SummaryFunc.Avg

    ' Set a range for which the function should be calculated. 
    summary.Running = SummaryRunning.Group

    ' Set the "ingore null values" option. 
    summary.IgnoreNullValues = True

    ' Set the "treat strings as numerics" option.
    summary.TreatStringsAsNumerics = True

    ' Set the output string format. 
    summary.FormatString = "{0:c2}"

    ' Make the label calculate the specified function for the 
    ' value specified by its DataBindings.Text property. 
    label.Summary = summary
End Sub
