I have a test form with textboxes and a combobox. I notice that the combobox is always enabled regardless of the BO.EditingState. Not a big problem as I know it can be handled in our own code, but I think it would be good if all editable controls respected the BO.EditingState.

Thanks.

Oops - I spoke too soon. I haven't bound the combobox to a field yet!

Sorry, it is still doing it after I have setup the combobox. It looks like the combobox is always enabled regardless of BO.EditingState.

The combobox does follow the EditingState.  The only reason it wouldn't is if:

1. You have the IgnoreReadonlyState property set to True on the ComboBox
2. Have the ManageReadonlyState property set to False on the BO
3. Aren't using an SF combobox.

Interesting, I am using a SF combobox and have checked your points:-

1. IgnoreManageReadOnlyState = false

2. ManageUIReadOnlyState = true for both the main form BO and the lookup BO

However, I can open the dropdown and select an item when the form is not in edit mode.

Well, then you have something else in the mix...this is a very basic control and basic functionality.  I know for a 100% fact that this control follows the editing state of the BO when bound...oh, that would be a 4th point (and the most basic one)

Do you have the control bound to a BO and binding field?

Binding to a BO field may be the most basic point but guess which dummy didn't do it?

I really didn't know what I was doing and originally bound to the field and ran the form without realising I had to setup the PopulationDataSourceSettings. It threw an error so I removed the binding and setup the PopulationDataSourceSettings. Of course the drop-down worked but it wasn't bound to the BO.

Now that I have bound to a field, guess what is working now? 10 points to you and a "fail" for me

By the way, is there anyway to show two fields when the drop-down is opened but only one field with the drop-down is closed?

I tried using the "Drop-Down Display Format String (Combo Only)" option but it didn't appear to do anything.

Thanks.

Hi Aaron.

Try something like this:

Hi Ivan,

I tried that and it doesn't work for me. All I see is whatever I have in the Display Member Format String box. If I do {1}{0} in Display Member then I see the two columns when the combobox is both open and closed. The Drop-Down Display Format String doesn't appear to do anything for me.

Maybe I am missing a property on the combobox to make this work?

Thanks anyway.
