What is the best way to have datagrid, including converters disabled with loading spinner?

I understand how fire my loading of start / end of load events when a datagrid is filled from external data. What I do not know how effecitively (and have been Googling) is what is the best practice to make the datagrid appear as modal with a top in top-load it?

My train of thought of the approach is - longshoring, Make existing datagrid not clickable, then set alpha to cloud the current data grid. Show a spinner of loading on top of the grid.

I can put the alpha that gives him the modal aspect, but how to ensure that the user cannot click on anything in the existing grid? Affecting the grid enabled = false classification of works, but there are icons in a converter of element in the grid which to are still clickable. Do I have to manually disable all schools?

Unfortunately, I'm surprised that Googling for this didn't turn out much. I know this must be a fundamental problem.

Here is the solution, check that it http://www.rphelan.com/flex/LoadCanvas/LoadCanvasExample.html

    If you have a form on the detailed view of the web application, and you fill in the fields, lets say 'product name' with the actual tag name as the value of the entry. So who will automatically fill.

    Given that the user has no need to change it, you can even hide the field filled with his car.

  • What is the best way to replace plan purchased from reseller with a similar plan purchased directly from Adobe?

    We have a creative cloud for plan teams purchased from a reseller. It is about to expire, and we consider substituting a plan purchased directly from Adobe.

    What will be the best way to do this?

    Should we start with purchase of new Adobes site map, before the expiry of the existing plan and then invite existing users to the new plan?

    Or is there a better way.

    If we do it in the wrong way users could lose access to Applications, which will be a major problem.

    Someone out there who have done this operation?

    Hello

    You will need to cancel the plan with the dealer first and then the Adobe purchase plan and assign licenses to users.

    You will need to contact support by calling/chat for this request.

  • What is the best way to have multiple languages in file an Illustrator?

    First of all, I'm quite new to Illustrator.

    I have a project where I need to display accurate translations of the different phrases in several languages. I'm unable to get all languages, that I need to display accurately and I would also need to share this project with my superiors so that they can see. I came across ScribeDoor that would be perfect, but it does support all the languages that I need.

    List of languages required: English, Dutch, Swedish, Russian, French, Finnish, Italian, German, Greek, Portuguese, Korean and Hebrew

    I think I just need to install fonts that support this language, but I can use the same font with different languages on the same project? And even then there at - it a plugin or something that I'm not aware of that will translate it accurately for me or I have to go to an outside source to confirm that?

    I use Adobe Illustrator CC 2015 on a MAC under OS X El Capitan 10.11.4

    It would be ideal if it was easily transferable to After Effect, as is the next step in the process.

    With your version, none of these languages should be a problem.

    Type of Arabic and Hebrew in Illustrator

    Your system also has fonts installed for all of them.

    If you want Latin, Asian, Hebrew and Cyrillic type to watch the same thing that you probably need to search commercial fonts that have been designed this way.

    Maybe (small chance) SIL.org has fonts with this wide range of characters.

  • What is the best way to have a significant amount of news stories on the site of muse?

    Hello, my company recently built a new site on muse from adobe.  We organize several magazine publications.  My boss wanted digital editions of magazines online and not having each individual story posted, so I thought that muse would work great for us, and it was.  But now it has changed its mind and wants it to view each story individually online and have it all searchable, including old stories.  I read that muse works best with 100 pages or less to a Web site, and after that which will run a lot slower and so that we can add all of these stories and keep an archive we have hundreds of pages.  Welcome us with business catalyst, so I do not believe that is an option to download the news stories there (please, correct me if I'm wrong).  is there another option for reporting host on the site other than to create hundreds of pages? Thank you very much for your help!

    For this, you can use accordion or composition. Add stories with label so that users can click on label for each story and this specific story will be displayed on the page.

    Apart from this, you can use any service of Blog and stories like blog notes:

  • I want to rename and move files from a shoot 5 d. I would like to use the functionality of the increment to count, but since I have to get out of each file to the following file, it starts again at 1. What is the best way to do it?

    I want to rename and move files from a shoot 5 d on a new drive. I would like to use the functionality of the increment to count, but since I have to get out of each file to the following file, it starts again at 1. What is the best way to do it?

    HI -.

    As a prelude to 2014.0, we have added a feature allowing you to choose what number to start the increment of.  Look in the section ingest Rename dialog and change your preset. When you click the button, you should see the option "Custom Auto Increment". This will allow you to choose what number to start on.  We've also added a few newspapers to try to remember where let prelude last successfully interfere the operation by using this option. So, in theory, to remember the number for you. But if it isn't (maybe you want multiple kickoff ingested at the same time) you can always manually set the number to start with.

    Check that out and let me know how it works for you.

    Kind regards

    Archive messages or move them to some other local mailboxes or mailboxes on the server. Don't know what you are trying to do because it appears that you have 2/3 of your hard disk.

    Why do you think archiving emails in 2 places? Where are you trying to save space to?
