Develop a specific level of a multi level Advanced DataGrid

I have an Advanced DataGrid (ADG) that displays three levels - we'll call it 'Parent', 'Child' and 'Child Detail' - using a HierarchicalData collection which is built from XML from a Web service (see attached code).

The ADG is generated as I do, and I'm able to develop all levels, as well as reduce all levels using the expandAll() and collapseAll() methods.

However, by default, I want the grid to display with the first level ("Parent") as the only open level. I can't find a way to do this, using existing properties and methods of the ADG class.

Does anyone have any suggestions?

Don't know not if anyone out there cares, but I found a better way to do it. I was forced to find a new way since FB3 Beta2 no longer supports the 'openItems' mx.controls.AdvancedDataGrid property. See code attached for the solution.

Notes:

'This' is the ADG as a Flex component

  • How can I set a few seconds from the beach to the specific level of db?

    Hi all, I'm new to this software,

    I want to know how can I put a few seconds from the beach to the specific level of db?

    For example, I just want the maximum dB higher and the low dB to be only 3.

    the sound is more concentrated.

    How can I do?

    Ah, you mean compression. There are several tools in hearing that, and one to use depends on the source material. If it is spoken word, then you can use dynamic processing tool (the original), the single band compressor or, possibly, the leveller speech volume to achieve this goal. If it's music, then the multiband compressor is rather sweet.

    But with each of them, there is something important, you should firstly to your track, and it is to normalize it to 0 dB using Effects > Amplitude and Compression > Normalize. You should do this because all compressor settings are associated with a full range signal (i.e., 0 dB) to treat. If you do not do this, none of the controls will make sense. On your screen that you've expanded the display to make it much larger than it should be, then you might want to get back to normal, otherwise you will not see clearly what is happening. Hearing can artificially display any amplitude of the signal at all, due to floating-point processing system internal use, but in the real world, the audio device cannot handle more than 0 dB, please make sure that the signals exceed this.

  • Advanced DataGrid - you click columns to hide/show based on the level of the child

    I have a Flex application that displays an Advanced DataGrid with three levels in the tree. The default view displays a single column of data. When a child on the floor of the tree is opened, two additional columns are displayed. I want these columns to stay open as long as any kid on the floor is open. I can't find a way to make it work - I can get the columns to be displayed when the user clicks on the 2nd child of level, but I can't find a away from keep them visible until the last child at this level is closed (see my attached code). Is it possible to loop through all the items in the Collection of data to see which ones is open and access data associated to each?

    Attached code (a few pieces that are not connected have been omitted).

    Help, please.

    Thank you.

    Found my answer on my own. I basically loop in the table in the ADG openItems, save the reference that corresponds to the lowest level that is open, then set visibility of each column based on this criterion.

  • Refresh a specific BTF inside a multi taskflow.

    Hi all

    I've implemented multitasking flow binding as suggested in this blog which is very characteristic.

    Blog: Oracle ADF: extreme region: binding Multi-pre-task-flow

    I would like to refresh one of the task flow confined in multitasking flow bindings.

    If I add content to map of parameter of the delimited multitasking speed, all task flow links inside updated that is not my intended behavior.

    As I have several task flow inside the path of multitasking, I would like to refresh only certain task flow inside based on condition. Usually changing the stubborn the taskflow setting would have us help to refresh it.

    I tried to get handle to TaskFlowBindingAttributes and set the plan of setting for particular bounded TF I want to update but unfortunately its not refreshing.

    Can you please how this behavior can be obtained.

    --

    Kind regards

    B Madelon Bhat,

    Usually changing the stubborn the taskflow setting would have us help to refresh it.

    I tried to get handle to TaskFlowBindingAttributes and set the plan of setting for particular bounded TF I want to update but unfortunately its not refreshing.

    You cannot refresh taskflow by changing the value of the parameter if the taskflow use parameter mapping.

    Instead, you can use the property "cool Condition".

    So, you must define the variable RefreshCondition on TaskFlowBindingAttributes property for some EL who will evaluate to true for the instance specific taskflow.

  • Problems with the DC Power supply QL 355TP: I can not set the tension level

    Hello

    I'm trying to control a power supply DC via GPIB. The power supply being used is the QL355TP of society Thurlby Thandar Instruments (TTi). There are no drivers of OR to control the instruments, then I need to download and install the driver from the website of TTi: the package I installed is as follows:

    "QL - P power supplies, (including QL Series II) series pilot National instruments (Labview and CVI)"

    and I also installed the following:

    "QL - P power supplies (including QL Series II) series, IVI driver"

    So, my problem is that when I try to use the sample application of the driver 'Volts.vi DC Ouput'; defines a specific level voltage, does not work properly. The application gives no error, but it is not set the specific level voltage. However, other functions work properly, as the measure or activate the output. I tried a lot of things, but I don't know why it does not work.

    I enclose the block diagram of the application and the front panel:

    I must say that I barely control instruments using Labview and is possible that this problem would be because I did not consider things basic and mandatory.

    Any help is appreciated.

    Thank you.

    p.s. Try to replace the decimal comma to period. It is possible that the driver does not correctly handle the comma.

    When I watch Youtube videos, I would adjust levels volumn due to the sound quality of the video clip, but whenever I listen to my music using Windows Media Player, I have to tune down every time, and I need to make several times of all the days for these tasks. Anyone has any suggestions on how to set my volumn on any approach levels? so I need to manually set it down.

    For example:

    (1) reset volumn level each time the reboot window

    (2) creating a batch file for restore volumn level based on the expected period

    (3) adjust the volumn volume specific music files, whenever I play it, the level of volumn will automatically set at specific level.

  • How will I know that a privilege level is allowed to do

    We had an engineer that installing a privilege level personalized some time. As far as I know, it's still there. How can I make sure that this specific level is allowed to make? How to add or remove things from it?

    The configuration currently has a set of names of local users and devices is configured to use these user names the and their configured privilege level (currently "15" = full administrator privileges) for authentication and authorization by the following lines:

    username disaster privilege 15 secret 5 username svc-kiwi privilege 15 secret 5 username admjkude privilege 15 secret 5 username admprime privilege 15 secret 5 username svc-prime privilege 15 secret 5 username admpsing privilege 15 secret 5 username admkgen privilege 15 secret 5 username admtmcco privilege 15 secret 5 aaa new-model!!aaa authentication login default local line enableaaa authorization consoleaaa authorization exec default local 
    If new users have been defined with a lower privilege level (say '3' or '4'), they would be limited to the commands that appear in the next section of the config file:

  • creates if absent level

    Hello

    I'm creating a workflow that needs to create specific levels

    the problem and if it is already at the level should not create a new one.

    If the layer with the name exists 123456 should not do anything,

    If on the contrary the 123456 level does not exist, create it.

    According to you and why?

    [email protected],

    You can use a try for this catch clause:

    var aDoc = app.activeDocument;
    try {
        aDoc.layers.getByName ("123456");
        alert ("level alredy exists");
        // do nothing
        }
    catch (e) {
        alert ("level does not exists");

  • Measures at different levels of concentration

    I'm working on a cube. I have 6 dimensions and aggregations are supposed to do at different levels for me to get the correct results, but I'm unable to implement this. I I have a fact Table equipped with all measures, I need, including sales, quantity, amount Total savings, Total etc edits. The challenge is that these measures require complex calculations, so I have a level of data in the fact table, but I think that this is the origin of the problem. How can I build complex measures calculated in the Olap Cube using a sql statement. What are the functions I should use to do this.

    The challenge is that, I've separated the totals of the details and I don't know of a way to get consistent results with 2 levels of granularity of diff

    Thank you

    You must come with some examples to get a better answer.

    A few general points.

    *(#1). * for calculated measures, look at the Expression of OLAP syntax which resembles the features of relational analytical ROLAP.
    http://docs.Oracle.com/CD/E11882_01/OLAP.112/e23381/TOC.htm

    Use this syntax to create your measurements calculated (in minutes).

    In the "Calculation Type", select "Syntax of Expression of OLAP", and in the Expression box, type the logic.

    .
    *(#2). * If for any reason, an Expression OLAP syntax cannot be used because of some complexity, then you can use old fashioned OLAP dml syntax.
    http://docs.Oracle.com/CD/E11882_01/OLAP.112/e17122/dml_basics.htm
    http://docs.Oracle.com/CD/E11882_01/OLAP.112/e17122/dml_functions_1.htm#BGEGGBAE

    In the "Calculation Type", select "OLAP DML Expression" and in the OLAP DML type logic.

    .
    *(#3). * You can load the relational data into different levels of OLAP cube.
    Facts on multiple levels of loading

    .
    *(#4). * You can start the aggregation of the cube to a specific level in a dimension. It is very important, because the aggregation of the cube always go leaf-level and currently there is no way in AWM to set a higher standard as the starting point for the aggregation.
    For example, let's say your time dimension a YEAR-> QTR-> MONTH-> DAY levels, and you want to leave aggregation of quarter level and not at the level of the DAY.

    You can do DBMS_CUBE. Order IMPORT_XML and provide the following syntax, so that the cube is always aggregated level quarter.

    SUM WITH 'TIME' OF MEMBERS WHERE "TIME". LEVEL_NAME = "QUARTER."

    .
    .
    Regardless of the level of complexity are your calculations, it can be done by means of (#1) ou (2).
    Best is to use "syntax of Expression of OLAP.

    I mentioned (#3) and (4) just to make you aware of other available functions.

    .
