    Can I add a blank grid section to an application

    Hi,

    I can't recall if this is possible.
    In a JavaScript application, I am trying to add a blank grid and then populate it later from an array using additems().

    I know this is not yet supported in custom sections, but I thought it may be possible in a standard section.

    Thanks.

    Herb

    Here's what I did in on app:

    1) created a table with the required fields and also had a cSession field of C(26).
    2) in the UI, I added a property to a public var oApp of cSessionID
    3) this property was, on the INIT of the UI app, set to guid() (this was in VFP, but should work here)
    4) I then set a filter on the grid of: cSessionID = oapp.cSessionID -- which meant the grid was showing empty
    5) Then I could "create" records from anywhere, making certain to use oapp.cSessionID as the cSessionID of the table.

    The same could be done with a VT and a parameter for cSessionID of course.

    In the close of the database (assuming you don't close it in the UI), you can delete for cSessionID = oapp.cSessionID.

    hth,

    Hi Hank,

    I have an odd requirement.
    The app has to be an executable, so electron looks perfect.
    It is a disconnected app that has no database and needs to be installed all over the globe as just an executable and some support files.
    All of the data is coming from already existing web services. So I am decoding json data with getUrl and json_decode.
    If it was a normal lianja desktop app or web app, I could build it in my sleep.

    I will try a temp table/cursor on init and see if I can get that to do what I want.

    Thanks.

    Herb

    Hi Herb,

    until we get disconnected data (it's in the roadmap, currently for 4.1), that will not work. The cursor never exists on the mobile client: JSON record(s) are sent from the server, and updates are sent back by JSON.

    When we get disconnected data, it will be a piece of cake. The JSON sent and modified will exist in some form of local storage.
