GetVariableText Method (SummaryRow)

Retrieves the string equivalent of variableName used when dynamically resolving the variables specified in the TextFormat property.

Syntax

Visual Basic
C#

'Declaration
 
Protected Overridable Function GetVariableText( _

   ByVal variableName As String _

) As String

'Usage
 
Dim instance As SummaryRow

Dim variableName As String

Dim value As String

 

value = instance.GetVariableText(variableName)

protected virtual string GetVariableText( 

   string variableName

)

Parameters

variableName: The name of the variable to resolve. Does not include the % characters.

Return Value

The string equivalent of variableName.

Remarks

The following variables are supported by default:

%COLUMNFIELDNAME%	Represents the value of both a column's GroupBy and FieldName properties.
%GROUPKEY%	Represents the value of a group's Key property.
%GROUPTITLE%	Represents the value of a group's Title property.
%DATAROWCOUNT%	Represents the value returned by the GetSortedDataRowCount method when its recursive parameter is set to true.
%COLUMNTITLE%	Represents the value of a column's Title property.
%COUNT: %	The result of the Count statistical function.
%MAX: (see below for usage)/%	The result of the Maximum statistical function.
%MIN: (see below for usage)/%	The result of the Minimum statistical function.
%SUM: (see below for usage)/%	The result of the Sum statistical function.
%AVG: (see below for usage)/%	The result of the Average statistical function.
%STDEV: (see below for usage)/%	The result of the Standard Deviation statistical function.
%STDEVP: (see below for usage)/%	The result of the Standard Deviation Population statistical function.
%VAR: (see below for usage)/%	The result of the Variance statistical function.
%VARP: (see below for usage)/%	The result of the Variance Population statistical function.
%MEDIAN: (see below for usage)/%	The result of the Median statistical function.
%MODE: (see below for usage)/%	The result of the Mode statistical function.
%GEOMEAN: (see below for usage)/%	The result of the Geometric Mean statistical function.
%HARMEAN: (see below for usage)/%	The result of the Harmonic Mean statistical function.
%RMS: (see below for usage)/%	The result of the Root Mean Square statistical function.

In the case of the variables that represent statistical functions (COUNT, MAX, MIN, SUM, AVG, STDEV, STDEVP, VAR, VARP, MEDIAN, MODE, GEOMEAN, HARMEAN, and RMS), additional parameters must be provided within the variable after the colon (:). These parameters are the fieldname of the column from which the data is retrieved, the (optional) format specifier with which the result of the statistical function is displayed, and the (optional) group level for which the statistical function is calculated.



%COUNT: ["]column_fieldname["] [ format=["]format_specifier["] ] [ level=running_stat_group_level ]%

All items placed in square brackets [] are optional. If the column_fieldname and/or format_specifier parameters contain spaces, quotes must be used. If a running_stat_group_level is not specified, -1 (current group) is assumed.

When overriding GetVariableText in a derived class, base.GetVariableText( variableName ); must be called first. If a string is returned, then the variable was successfully resolved. If System.String.Empty is returned, then the override should be able to resolve the variable.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
