How to verify if selected combobox item is disabled?

[Paco75]

Hi,

Let say i got a combobox initialised like this

this.RowSourceType = 1
this.RowSource = "item1,/item2"

how can i validate if selected item is disabled or not?

 

[JRB-Bldr]

selected item is disabled or not

What do you mean "disabled or not" ?

Disabled where?

If it is Disabled in your Combobox, then it should not be an available option to select.

If it is Disabled somewhere else, your own code will need to check it and do whatever is necessary.

Good Luck,

The combo box i loaded with a list of items that some items will have a "/" before to disable them. Depending on many things the same combo box will have the same items but some will be disabled inside.

example the same combo box can have these list:

combobox:
- "item1"
- "item2"
- "/item3" && Disabled in combobox
- "item4"

combobox:
- "/item1" && Disabled in combobox
- "item2"
- "item3"
- "/item4" && Disabled in combobox

i need to verify if the first combobox item is enabled because sometime the form is loaded and the combobox is placed on the first item even if it is disabled.

My first thought is that none of your items will be disabled.

The escape character is a backslash, not a forward slash

\Item1 && disabled

My second thought is that this may not be natively possible.

You probably need to populate the list from a two dimensional array (value, endabled) and then test your value against that list.

There is no way to access an item from a combo box and read it's properties?

PS: Yeah you are right i put slashes in my post but in my code it was back slashes... mistyped!

Just check the item itself. If you're in code in the combo, use:

This.List[1]

for example, to look at the content of the first item. You can then check for the "\"

That doesn't work in VFP9 Tamar, the \ escape character is NOT passed back.

Uh, are you sure? Doesn't work that way for me. <s>

Hi,
To varify check only for (citem,1)="\" will only work if you never have to add an item which begins with a \. You should also check for left(cItem,2)="\]".
Since you most probably populate your combo with an array, you could also consider to add an extra dimension to your array "disabled" and populate that column with .T. if condition is true and check your array column on disabled=.f.

If that is what you want, then why are you 'populating' your ComboBox with Values?

Why not set the ComboBox up with its RowSourceType = ALIAS and then just manipulate the Records (DELETE/RECALL) in the associated Cursor/Table as needed (example: SET FILTER TO !DELETED()) to Enable/Disable the 'rows' shown in the ComboBox?

It would be much easier than depending on an ESC character in the Values data itself.

Good Luck,

Sorry. I wrote off the top of my head without testing. I was mistaken.

FWIW
see thread184-1659274
There's a bug which allows you to select a disabled item using keyboard.
