Arul,

I do not get what you are talking about ,

well the expression uses the Set modifier for the No=9and call variable vDataLanguage

In the expression, they are using a variable: vDataLanguage.

Go to Settings and Variable Overview, you would find its value.

vDataLanguage is a variable which holds the mystery. Goto Settings->Variable Overview, you will find what the variable contains. Rest is set analysis to say get that variable expression value when a 'No' field has a value 9.

hi itsangad,

the variable having some value so what is the use of this code?

This expression would return the value of that variable when No =9

{No=9} will act as a filter or where clause as in database language.

Where is to rest is set analysis and where is the Product Category name came from?

The expression is used in Title section.

Please look below, the Field Section. There you will find the ProductCategoryName field. This the field which is populating the data.

Hi,

Check the variable expression, in that it must have mentioned field on basis of which that particular name "product category" is shown.

Hello Arul,

I found it.

Create a Table Box, with below fields:

No and English

you will see for each number, they have a English Text. And that text gets displayed at the Listbox title.

similary u will find fields like Japanese, English etc

hi Shruthi

i checked the expression but there is no name

Re: Title In listbox Properties

Thu, 23 Jan 2014 07:14:15 GMT

So your Title expression becomes : =Only({<No={9}>} English)

where English is a field name. So the text corresponding to No =9, that will shown at Title

Hi,

I checked it. It mentions "Language" which is a data field which comes from script. You can check it taking it as List box.

ya it looks like this...

so the number holds the name?

Re: Title In listbox Properties

Thu, 23 Jan 2014 07:22:44 GMT

try it with if

if(No=9,$(=vDataLanguage))

Re: Title In listbox Properties

Thu, 23 Jan 2014 07:24:31 GMT

Yes, it is like mapping Text with Numbers.

So in the expression you are using set analysis when you use {<No={9}>}. This means to select No as 9

and then when we embed it with Only() it returns the Text corresponding to English field name where No is 9 i.e Product Category in your case.

Let us know, if you come across any other issue. And can close the thread if you have got all your answers.

Thanks,
