Values
| Name | Value | Description |
|---|---|---|
| None | 0 | Means the extended attribute has no lookup table of formula and simply stores value set by the user. |
| Lookup | 1 | Means the value of the extended attribute is restricted to values from a lookup table. |
| Formula | 2 | Means the value of the extended attribute 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);
