Preventing editing table fields by condition – 1Ci Support

Scope: managed applications.

Best practices

In some cases, you might need to inform users that the data entry is invalid or impossible until some required fields are filled in. To do so, employ the following approach.

To set up the warning, use the WarningOnEditRepresentation and WarningOnEdit properties.
Select the field in Designer and specify the warning text in the WarningOnEdit property.
Change the value of WarningOnEditRepresentation programmatically when the field is activated and the conditions change.
Grant users the right to edit table entries, including the ones that don't meet the conditions.

Example. The Costs form has a table with the CostItem and CostItemDimension fields. To fill in the CostItemDimension field, users have to specify CostItem first. The code sample for this use case:

&AtClient
Procedure SetWarningOnEdit()
   If NOT ValueIsFilled(Items.Costs.CurrentData.CostItem) Then
      If NOT ValueIsFilled(Items.Costs.CurrentData.CostItemDimension) Then
         Items.CostsCostItemDimension.WarningOnEditRepresentation =
WarningOnEditRepresentation.Show;
      Else
         Items.CostsCostItemDimension.WarningOnEditRepresentation=
           WarningOnEditRepresentation.DontShow;
      EndIf;
   Else
      Items.CostsCostItemDimension.WarningOnEditRepresentation=
        WarningOnEditRepresentation.DontShow;
   EndIf;
EndProcedure

&AtClient
Procedure CostsOnActivateRow(Item)
   SetWarningOnEdit();
EndProcedure

&AtClient
Procedure CostsCostItemOnEdit(Item)
   SetWarningOnEdit()
EndProcedure

&AtClient
Procedure CostsCostItemDimensionOnEdit(Item)
   SetWarningOnEdit()
EndProcedure

If the warning text is also conditional, change the value of WarningOnEdit programmatically.
