Truble with dialog

Question

public PXAction UpdateHours; [PXUIField(DisplayName = Messages.UpdateHours, MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select)] [PXButton(DisplayOnMainToolbar = false)] public IEnumerable updateHours(PXAdapter adapter) { if (MaintenanceLogInfo.AskExt(UpdateHoursSetVisible, true) == WebDialogResult.OK) { DateTime date = MaintenanceLogInfo.Current.Date.GetValueOrDefault(); decimal hours = MaintenanceLogInfo.Current.Hours.GetValueOrDefault(); if (date == null) { // Acuminator disable once PX1051 NonLocalizableString [Justification] MaintenanceLogInfo.Cache.RaiseExceptionHandling( MaintenanceLogInfo.Current, date, new PXSetPropertyException(Messages.DateCannotBeEmpty) ); return adapter.Get(); } if (hours < 0) { // Acuminator disable once PX1051 NonLocalizableString [Justification] MaintenanceLogInfo.Cache.RaiseExceptionHandling( MaintenanceLogInfo.Current, hours, new PXSetPropertyException(Messages.HoursMustBeGreaterThanZero) ); return adapter.Get(); } AddOrUpdateMaintenanceLog(date, hours, false); } return adapter.Get(); }When I enter a value < 0 in the Hours field, keep focus on that field, and click OK, the dialog closes without showing the validation error, even though I confirmed with debugging that the if (hours < 0) block is executed.How can I prevent the dialog from closing and properly display the validation error when the value is invalid?

Make the ‘OK’ button conditionally enabled.

To disable a dialog button:

Add a PXButton action in code (using the primary DAC type)
Associate the button in ASPX by setting CommandName and CommandSourceID = ds
Set the SyncVisible="True" property on the ASPX button

Set the enable/disable logic in the RowSelected event of the dialog DAC type:

protected virtual void _(Events.RowSelected<DXSplitFilter> e)
{
    DXSplitFilter row = e.Row;

    if (row is null) return;

    bool timeSpentEqualsOrig = row.TimeSpentSplit1 + row.TimeSpentSplit2 == row.OrigTimeSpent;

    bool billableTimeSpentEqualsOrig = row.BillableTimeSpentSplit1 + row.BillableTimeSpentSplit2 == row.OrigBillableTimeSpent;

    splitDialogOK.SetEnabled(timeSpentEqualsOrig && billableTimeSpentEqualsOrig);
}
