How to filter one column based on another when creating a select field?

Hi Folks,

Say, I have a table like this:

COL1
Visible
1yes
2yes
3no
4no
5yes

Normally I can create 2 fields: COL1 and Visible. COL1 shows all values (1,2,3,4,5) and Visible shows 'yes' and 'no'.

When I select 'yes' in 'Visible' manually, 1 2 5 will be white in COL1 and 3 4 will be greyed out.

But how can I create COL1 field with a condition so that it can by default show only 1 2 5 without having the user manually selecting 'yes'? (In this case I don't need to create the 'Visible' field at all)

Is it possible doing so without creating new tables?

I am aware there is a "conditional" checkbox in every field's Properties - Expressions tab. Is it the right place to look at? How to write the condition?

Thanks,

Jeremy

Hi,

It is possible with set analysis (see the file attached).

Adding to my original question, considering I have another table with the one above:

COL1COL2
1A
2B
3C
4D
5E

These 2 tables will be connect by column COL1.

I also want to create a select field that only shows A B E from COL2. That is, it filters the 2nd table's row based on a colume in the 1st table.

Is it possible?

Thanks.

Do you mean adding a expression in the "Expressions" Tab?

I tried, but the result looks very strange. It shows 2 columns. One is 1 2 3 4 5, the other is 1 2 - - 5.

Please check the screenshot:

Any idea?

Thanks. It looks great!

Can you explain a bit more by words? I am not that familiar with QV now. By looking at the screenshot I can't figure out how did you do it.

Thanks.
