Dynamic restrict data in List box

Anonymous — Thu, 06 Jun 2013 18:48:24 GMT

Hello,

I have list box with field from table - table containts records with calendar data - from this field is creating menu for years - actually 2007, 2008, 2009 ... 2013.

I can restrict values in list box, because 99% users are working 2012 and 2013.

But I can't restrict all data in script - reload application is more time-expansive and when some user can all years, I have to give it to him immediatelly.

So, I'm searching for possibility restrict values in list box in design, in properties? Ideal: I create some variable, on demand of value this variable I'll show complete year values or only restrict.

Do you know some way?

Thanks,

Olda

Use an expression for your listbox instead of a field. For example =if(Year>2011,Year) to show only years larger than 2011. Instead of 2011 you could use a variable to make it more dynamic (ie change the value of the variable instead of the expression).

Hello,

I tried create expression =Year (it's field from table) and then condition for Show, but List box was full of ##- instead of really values and count of values was same as years 2007-2013.

Do u need restriction in list box, use if(Year > 2010, Year) in listbox expression option..

If u need to use in variable and use in many place means, ALT+CTRL+V and add variable vMaxYear and Then give 2010..

Wherever u need, use like this

=if(Year > vMaxYear, Year) or in expression like this sum({<Year = {'>=$(vMaxYear)'}>}Sales)..

Hope it helps

Many thanks, I understand it, before I started the new expression and condition for visibility. When I replaced field with expression, all is OK.

Thanks,

Hello Gysbert,

I try one more question: when I have shorter lis of values, can I set new width of ListBox depend on condition for values? For example, full List box have 200 px, when I restrict list box only for last 3 year, I can set width 120 px.

Is possible to use some trigger on sheet?

Thanks,
