Looper control question.

Hi all,

I have a question regarding a Looper control that I'm trying to get working - it's my first Looper Control, so go easy on me :confused:

I have a Looper Control on a window and it is linked (via the Content tab) to a file (let's call it Specification_Definition) and there are 4 fields from this file defined in the looper control. Now my difficulty comes when I want the user to be able to select a product in each row in the looper (the product file isn't related in the Analysis). To this this end, I've tried placing a combo box in the looper which lists the Products for selection - so far so good (I thought)!

This combo box lists the required products and allows the selection of a product, but when I move focus to a different row of the looper, the selection of the product in the combo is lost. I thought the selection would be retained :confused:

I thought I would be able to let the user make their product selections on each of the rows they wanted to, then (when they press an OK button for example), I could work through the looper rows simply creating a Specification_Quote (with Quote_Lines) for each row of the looper - but no

Do you have any thoughts? Do I need to maintain the Product ID's that have been selected in a separate array (that maps across to the looper), for instance or is there an esier way that I'm missing?

Thanks in advance...

Hi Darren...

your looper is directly linked to a file, and in that case (same as a table directly linked to a file), only the visible elements/lines are loaded in memory at any given time.

Which means that any memory/calculated/entered content on a line that becomes not visible (scroll down situation) is lost. In your case, it's the selection in your combo...

So you can either use a MEMORY looper and load it programatically (in that case, everything is loaded in memory and your combo selection will stay with your lines) _OR_ you can keep your FILE looper and manage a separate array or memory zone in which you store the line selected (in the code selection of a line of the combo) and from which you take the selected line in the code display of a line of the looper...

Best regards

Hi,

Okay, I've coded an array (memory zone) that holds the product ID that is selected by the operator.

I may be missing something - I know I can display the selected product in the combo box when the looper row is selected (Row Selection), but is there a technique to show the product that has been selected in the combo box even when the looper row isn't selected?

Cheers...

Hi Darren,

as I was saying:
"... in the code display of a line of the looper..."

Not the the line selected, the Code for the DISPLAY OF A LINE

Best regards

Hi Fabrice,

Thanks for getting back in touch - sorry I didn't pick-up on the row display bit of your reply - now I've got it - I'll give it a try asap :spos: I'm sure it'll work...
