SelectEdit : Handling for No-Match

[brettwinters]

Hi @stsrki

Currently if the SelectedValue does not match any of the SelectItems, the SelectEdit displays the first item. This is a problem since the displayed value does not match the actual value.

This issue mostly occurs with initial values (null, empty, etc) when the model is initialised and nothing has yet been set yet, or due to a logic change previous set values are no longer in the list

Options :

(1) Allow users to set Visibility on SelectItem so we can do this :

<SelectItem Value="default(int)" style="display:none;">None</SelectItem>

Then the initial value is initially set to this item, and displayed in the select as "None", but once the user selects away from this default SelectItem its no longer visible/selectable. Visibility was fixed here ( #183 ) but not for SelectItem

as a work-around, I'm doing this now, but using your Class since the style is not available for us (yet).

(2) Allow us to set the title attribute on the select (but this option is mostly used if none of the items match - not necessarily if it matches the default) say by a property on the "SelectEdit" which allows us to specify what to display if nothing is selected, like this:

<SelectEdit NothingSelectedText="None" SelectedValue="0"
    <SelectItem Value="1">one</SelectItem>
    <SelectItem Value="2">two</SelectItem>
    <SelectItem Value="3">three</SelectItem>
</SelectEdit>

Then in this case the select would display "None" (not "one" as currently). In this case you'd
Then you'd have to add the add the title yourself

Preferred : allow all options

If I understood you correctly you want to have an item field that will internally be used to represent an empty or default item? So for example if NothingSelectedText attribute is used than there would need to be created SelectItem with default value and NothingSelectedText for the display?

I think your first example is the best way to go for, as it's not hiding a behavior from other developers.

yes, you understood correct.

Yes, agreed

Going to 0.8.5 since it is pretty easy to do.
