How to delete the contents of a Datagrid?

Hi all

I want to delete the contents of a datagrid and be able to display the content again as needed.

I have two selectors datefield, two buttons. A button to view the log of the datagrid. Another button to delete the data grid.

< mx:HBox width = '100 percent"height ="100% ">
< mx:Label text = "From" / >
< mx:DateField id = showToday "dateFrom" = "true" enabled = "true".
formatString = "MM/DD/YYYY".
disabledRanges = "{[new Date(), {rangeStart: new Date()}]}" / >
< mx:Label text = 'To' / >
< mx:DateField id = showToday "dateTo" = "true" enabled = "true".
formatString = "MM/DD/YYYY".
disabledRanges = "{[new Date(), {rangeStart: new Date()}]}" / >

< mx:Button id = "btn1" label = "see the error log" click = "getErrorLog ()" / >

< mx:Button id = "btn2" label = "clear all" click = "clear ()" / >
< / mx:HBox >

But once I have delete the contents of the DataGrid, I'm not able to load the data again. I delete the content by using the following function:

private void clear (): void {}

dateFrom.text = "";
dateTo.text = "";
CDL of the var: Array = errorLogTable.columns;
var size: int = errorLogTable.columnCount;
cols.splice(0,Size);
errorLogTable.columns = cols;

}

errorLogTable is the id of my datagrid.

Remove all your columns is required?   in your code you not delete content, you delete all the columns.so, next time you have some columns to display the data. If you want to see empty DG, then use the following syntax.   errorLogTable.dataProvider = new ArrayCollection();

  • How to replace the contents of the settings/passwords backup server / current browser bookmarks?

    Classic scenario: after the bookmark long manual organization Firefox Sync adds trash of its server to my laptop or tablet.

    Where can I find how to replace the content of the backup of the server by settings/passwords / current browser bookmarks? Stupid me, I put a new synchronization and lost this ability.

    It is not recommended to go back to the old version of Sync

    The old version is removed he'll stop being available soon, it takes getting used to using the new version.

    IIRC, it is actually possible to force synchronization of the old working with Fx29 & Fx30 using an old profile or preferences of piracy, but I don't think I should encourage users to try this, but it would be better than using an older version of Firefox which is really bad. In fact using an old outdated version of Firefox is so bad, that it is customary to recommend using a browser on alternative day of someone else instead.

    Firefox ESR is aimed at corporate users, definitely, at the moment, it will use the synchronization of the former. Who will update soon to use synchronization well again, and this time, I guess the synchronization of the former will probably totally frowned upon for example are not available at all.

    It is possible to use the feedback system to leave a short comment on Sync. I would recommend this making, but at least to make very many people of spirit comments that I doubt will have no effect.

  • What happens if I delete the contents of the my SubscriptionPlayCache folder in iTunes?

    Hello world

    I'm on a MacBook Pro (El Capitan 10.11.2, 2.4 GHz/4 GB), with 121 GB of Flash storage and I'm running out of hard drive space.

    I got a new time Capsule recently and more backups were transfer files to this (pictures, videos, etc.), but I just noticed the iTunes cache - specifically "SubscriptionPlayCache" has 9.1 GB of data in it. I regularly listen to music while I work, then, of course, that this has been over time.

    Will be the rumble of coming world down if I delete the contents of this file, leaving the folder itself in place (to begin its inexorable March upward the Hill of filling of storage)?

    Thank you!

    Music files Apple cache: http://dougscripts.com/itunes/2015/09/new-flush-apple-music-cache-files/ - ~/Library/Caches/com.apple.iTunes/SubscriptionPlayCache/ file, which is a bit like a "iTunes Media" folder for music from Apple

    You might find yourself with a bunch of broken links in iTunes for tracks pointing to these files. You could always delete those that many find that painful and unsightly to have them even.

  • How to delete the files from my HP ePrint app after download / print?

    Can someone tell me how to delete the files from my HP ePrint app after that I downloaded and printed. Thank you

    jmsandkds,

    I apologize for the confusion. Options you speak of "photos, web and file" are located on the phone somewhere, lets say you click files. When you click on files, it will search the phone for available files that are able to print the ePrint app. To the extent where they are on the phone, you will need to search for them via the search screen, connection to the computer, or some files are program specific and only available in this program to be read, edited, or deleted.

    I hope this helps.
