Re: Search in ADG
After you scrollToIndex, if you set horizontalScrollPosition, does anything happen? And then if you read back horizontalScrollPosition, is it non-zero? -Alex On 12/3/13 6:40 PM, "Oleg Konovalov" wrote: >Hi, > >I have a Flex App where on several tabs (TabNavigator) I have MX >AdvanceDataGrid's (wrapped in Spark Scroller's), which are dynamically >populated (so I don't know in advance about 1/2 of Columns). >Since the number of columns can be 200+, I am trying to implement a Search >within Column Headers and data, one by one kind, so that when match is >found, it highlights that cell >or at least highlights that row and displays that column, brings it in >user >view. >So far it shows that row, but I never was able to scroll to that column, >so >user can see it. >I tried to use ADG's horizontalScrollPosition, verticalScrollPosition, >validateNow with scrollToIndex,... >When I try to set selectionMode="singleCell", that sometimes seem to >freeze >the app. > >Any advice or code snippet how to scroll to that matching Column? >How to highlight the header and/or cell ? > >Can the problem be in that Scroller? > >Any help is very appreciated. > >-- >Thank you in advance, >Oleg.
RE: Search in ADG
MX components manage scrolling internally, Spark Scroller is used for spark skins only.

RE: Search in ADG
Also, set ADG.scrollHorizontalPolicy to "on", then simply calling ADG. horizontalScrollPosition = will do the trick. -Message d'origine- De : Maurice Amsellem Envoyé : mercredi 4 décembre 2013 08:36 À : 'dev@flex.apache.org'; flex-...@incubator.apache.org; flex-users-subscr...@incubator.apache.org Objet : RE: Search in ADG MX components manage scrolling internally, Spark Scroller is used for spark skins only.

Re: Search in ADG
Maurice, I did try adg.horizontalScrollPolicy="on" and adg.horizontalScrollPosition= - did not do a trick. And that adg.horizontalScrollPolicy="on" or "auto" only allowed me to scroll about 1/3 of columns, the rest is not visible.

RE: Search in ADG
I just did the test with 70 columns, and the ADG scrolls correctly, until the last column, whether manually by playing with the scrollbar, or programmatically. Can you scroll to the last column using the horizontal scrollbar , or does it stop to 1/3 of columns ? Can you try with fewer columns ( 70 instead of 200+) to see if it scrolls to the last column ? Anyway, I don't think adding a scroller to your ADG will solve your problem: you will run in performance issues, because the table will compute rendering for all columns, even if 10 are actually visible.
