Allow to calculate expression even when report is not running #810
Description
Is your feature request related to a problem? Please describe.
Right now it's not possible to get report parameter value with specified expression (for ex. Year([Date])). When you calling Report.Calc(parameter.Expression) the null value will be returned:
private bool TryCalc(string expression, Variant value, out object result)
{
result = null;
if (!IsRunning)
return true;
Describe the solution you'd like
When the TryCalc is called, don't check if report is running, because Parameter.Value prop already has this check:
public virtual object Value
{
get
{
if (!String.IsNullOrEmpty(Expression) && !Expression.Contains("[" + Name + "]") && Report != null && Report.IsRunning)
value = Report.Calc(Expression);
return value;
}
Describe alternatives you've considered
As a workaround I'm calling hidden method:
report..PreparePhase1();
