Specifies the type of a calculation of the custom attribute’s value for summary rows.

public enum SummaryRowsCalculationType

Values

NameValueDescription
None0Means the custom attribute’s value for summary rows is not calculated.
Rollup1Means the custom attribute’s value for summary rows is calculated using rollup function defined in RollupType.
UseFormula2Means the custom attribute’s value for summary rows is calculated using formula defined in Formula.

Examples

Shows how to work with calculation type of an extended attribute definition.

var project = new Project();

var task = project.RootTask.Children.Add("Task");
task.Set(Tsk.Start, new DateTime(2020, 4, 16, 8, 0, 0));
task.Set(Tsk.Duration, project.GetDuration(1, TimeUnitType.Day));

// create attribute definition with 'Formula' type where values for leaf tasks and summary tasks are calculated using formula.
var calculation = ExtendedAttributeDefinition.CreateTaskDefinition(ExtendedAttributeTask.Date5, null);
calculation.CalculationType = CalculationType.Formula;
calculation.SummaryRowsCalculationType = SummaryRowsCalculationType.UseFormula;
calculation.Formula = "[stARt]";
project.ExtendedAttributes.Add(calculation);

// create attribute definition where values for summary tasks are calculated using 'Average' rollup type.
var lookup = ExtendedAttributeDefinition.CreateTaskDefinition(ExtendedAttributeTask.Cost1, null);
lookup.SummaryRowsCalculationType = SummaryRowsCalculationType.Rollup;
lookup.RollupType = RollupType.Average;
project.ExtendedAttributes.Add(lookup);
