List Box filter

Tue, 19 Nov 2013 12:05:48 GMT

How can i exclude items out of my list box, for example I want to show just the top 10 items in the list box for my end user to select (completely excluding the other entries out of my list box).

I have got the formula that I can use but i cant see where if anywhere i can add this in as a condition?

Is this functionality possible using a list box?

Thanks

Jon

In the list box, at the end of the list of fields is the expression option. Use something like

If(Rank(Aggr(Sum(Sales), Customer)) <= 10, Customer)

for the list box expression

Yes,

Do sth like that in your Product ListBox, create your expression in the Field (General Tab):

=Aggr(If(Rank(Sum(Sales)) <11, Product), Product)

Hi,

Since your saying that "I have got the formula that I can use". And need to know how to use that formula. I have given the steps below.

Right click on the list box and open properties. Then go to general tab.

Click on the drop down that you see under "Field" label as shown below.

This will open up a list then select <Expression> from the list . This will open expression dialog box where you can enter your expression.

Thanku

Thanks for your answer,

The formula i have used is below which excludes and data where there is no cost or income (or thats what it is meant to do!)

This appears to work fine, and gives me a reduced list of options in the list box, however when i select one option instead of the other options turning grey as per a normal list box they are completey excluded.

How can i adjust my formula / settings to include all options based on the options filtered in the formula?

Aggr(If(
(
fabs(ROUND(Sum(COST)))+fabs(round(sum(revenue)))
) <>0, [Customer]),[Customer]
)
