FieldDefaulting handlers - acumatica

Question

I am having trouble setting default values for a filter on a processing page. I originally had code in the RowSelected handler to set the default values and set the end dates default as below:
//Local unbound filter DAC
#region StartShipDate
public abstract class startShipDate : PX.Data.IBqlField { }
protected DateTime? _StartShipDate;
[PXDate()]
[PXUIField(DisplayName = "Start Ship Date", Visibility = PXUIVisibility.SelectorVisible, Required = false)]
[PXDefault(PersistingCheck = PXPersistingCheck.Nothing)]
public virtual DateTime? StartShipDate { get; set; }
#endregion
#region EndShipDate
public abstract class endShipDate : PX.Data.IBqlField { }
protected DateTime? _EndShipDate;
[PXDate()]
[PXUIField(DisplayName = "End Ship Date", Visibility = PXUIVisibility.SelectorVisible)]
[PXDefault(typeof(AccessInfo.businessDate), PersistingCheck = PXPersistingCheck.Nothing)]
public virtual DateTime? EndShipDate { get; set; }
#endregion
#region StartImportDate
public abstract class startImportDate : PX.Data.IBqlField { }
protected DateTime? _StartImportDate;
[PXDate()]
[PXUIField(DisplayName = "Start Import Date", Visibility = PXUIVisibility.SelectorVisible, Required = false)]
[PXDefault(PersistingCheck = PXPersistingCheck.Nothing)]
public virtual DateTime? StartImportDate { get; set; }
#endregion
#region EndImportDate
public abstract class endImportDate : PX.Data.IBqlField { }
protected DateTime? _EndImportDate;
[PXDate()]
[PXUIField(DisplayName = "End Import Date", Visibility = PXUIVisibility.SelectorVisible)]
[PXDefault(typeof(AccessInfo.businessDate), PersistingCheck = PXPersistingCheck.Nothing)]
public virtual DateTime? EndImportDate { get; set; }
#endregion
//Excerpt from RowSelected handler
if (!filter.StartImportDate.HasValue && filter.EndImportDate.HasValue)
{
DateTime endDate = DateTime.Today;
DateTime begDate = endDate.AddMonths(-1);
filter.StartImportDate = begDate;
filter.EndImportDate = endDate;
}
if (!filter.StartShipDate.HasValue && filter.EndShipDate.HasValue)
{
DateTime endDate = DateTime.Today.AddMonths(1);
DateTime begDate = DateTime.Today.AddMonths(-1);
filter.StartShipDate = begDate;
filter.EndShipDate = endDate;
}
I then installed the latest Acuminator and it gave me a warning not to set DAC fields from within the RowSelected handler so I removed the code and attempted to set it in the FieldDefaulting handler. I can't seem to get the defaults to set correctly.
protected virtual void EDOrderReviewFilter_StartImportDate_FieldDefaulting(PXCache sender, PXFieldDefaultingEventArgs e)
{
EDOrderReviewFilter row = e.Row as EDOrderReviewFilter;
if (row != null)
{
if (!row.StartImportDate.HasValue && row.EndImportDate.HasValue)
{
e.NewValue = DateTime.Today.AddMonths(-1);
e.Cancel = true;
}
}
}
protected virtual void EDOrderReviewFilter_StartShipDate_FieldDefaulting(PXCache sender, PXFieldDefaultingEventArgs e)
{
EDOrderReviewFilter row = e.Row as EDOrderReviewFilter;
if (row != null)
{
if (!row.StartShipDate.HasValue && row.EndShipDate.HasValue)
{
e.NewValue = DateTime.Today.AddMonths(-1);
e.Cancel = true;
}
}
}
Is there a way to do a date calculation in the PXDefault attribute, or what is wrong with my defaulting handlers?

With Brendan's help, this is what I ended up with.
protected virtual void EDOrderReviewFilter_StartImportDate_FieldDefaulting(PXCache sender, PXFieldDefaultingEventArgs e)
{
e.NewValue = DateTime.Today.AddMonths(-1);
}
protected virtual void EDOrderReviewFilter_EndImportDate_FieldDefaulting(PXCache sender, PXFieldDefaultingEventArgs e)
{
e.NewValue = DateTime.Today;
}
protected virtual void EDOrderReviewFilter_StartShipDate_FieldDefaulting(PXCache sender, PXFieldDefaultingEventArgs e)
{
e.NewValue = DateTime.Today.AddMonths(-1);
}
protected virtual void EDOrderReviewFilter_EndShipDate_FieldDefaulting(PXCache sender, PXFieldDefaultingEventArgs e)
{
e.NewValue = DateTime.Today.AddMonths(1);
}
Since there are no PXDefault attributes on the columns the cancel was not required. Sometimes simpler is better!
