Filtering data grouped in Advanced DataGrid

I want to display hierarchical data (data groping) in advance DataGrid and at the same time I want so the filtering feature. The problem is that if I want grouped view then I provide GroupingCollection the dataprovider (which has no function filterFunction type functionality).
Is it possible to fix this?

I found the solution.

1. store the data collection ArrayCollection (say ac).

2 - ac.filterFunction = processFilter / / some filter function

3 assign this collection for GroupingCollection ArrayCollection (say gc) as a source.
GC.source = ac

4 assign gc as dataProvider of dataGrid

5 - when you want to apply the filter:
ECL Refresh();

    I am able to fix it a little weird.

    On the complete creation of my application, I'm calling the next method. Where requested.dataTipField = columnIndex.toString (); stores the index of the year.

    protected function creationCompleteHandler(event:FlexEvent):void {

                                        var columns:ArrayCollection = new ArrayCollection(surveyGrid.groupedColumns);                                        var years:Array = summary.getItemAt(0).Year as Array;

                                        for (var columnIndex:int = 0; columnIndex < years.length; columnIndex++) {

                                                  var year:Object = years[columnIndex];

                                                  var gridGroup:AdvancedDataGridColumnGroup = new AdvancedDataGridColumnGroup(year.Label);

                                                  var requested:AdvancedDataGridColumn = new AdvancedDataGridColumn("Requested");                                                  requested.dataTipField = columnIndex.toString();                                                  requested.itemRenderer = new ClassFactory(YearGridRenderer);

                                                  var completed:AdvancedDataGridColumn = new AdvancedDataGridColumn("Completed");                                                  completed.dataTipField = columnIndex.toString();                                                  completed.itemRenderer = new ClassFactory(YearGridRenderer);

                                                  gridGroup.children = [requested, completed];                                                   columns.addItem(gridGroup); 

                                        }

                                        surveyGrid.groupedColumns = columns.toArray();                               }

    Then associate ItemRenderer did the trick.

  • Advanced Datagrid grouping

    We have doubts about the grouped columns of the Advanced DataGrid.

    With the following XML as a data source for an advanced Datagrid component, we would like to know how to group the data taking into account the tag "Cgrpm". Just to explain, that we want to create a group header to level two, the first thing is to group the data by "Cgrpm" and show all left entries in the XML. It should look like this:

    000054 00000058
    		00000034 ...
    EntryLeaveCalday...
    2009-08-112009-10-012009-10-01...

    I hope that someone could help us.

    Thanks in advance for your help.

  • Structure of the tree in advanced datagrid

  • iconfunction in Advanced Datagrid

    I am specifying a 'iconfunction' in my advanced datagrid - works but

    not quite as you want.

    I have two flavors of data in the grid: directory (a) and (b) database

    The directory icon, I can easily specify a folder icon. It don't

    not, seems to me to be a way to change this picture in an open folder

    vs file is closed with a click. The icon is what is specified in the

    the function of the icon.

    I tried without success itemclose, itemopen.

    Specification of a default icons game works except that empty

    Directory presents itself as a sheet and pick up the database icon.

    This is not what I want.

    Is it possible to have the best of both worlds?

    TIA, Chris

    Hello

    the only option for you is to use iconFunctions and itemOpen and itemClose eventListeners.

    ItemOpen and ItemClose eventListeners, you must change the property (for example _isOpened) in dataProvider to distinguish open and closed directories.

    IconFunction, you should check this property and the type of data to return the correct icon.

    Hope this helpful.

  • DateFormatter in advanced Datagrid

    Hi all

    I am trying to format a date field in the advanced datagrid control, but it displays the incorrect date. It displays either 100 or 2000.

    The data from a webservice and I convert data from the Web service in an arraycollection collection and each element of the arraycollection collection is of a custom type. One of the fields of custom type is a date.

    «The data show in the advanced datagrid correctly but a very long form for example"sea Mar 19 15:55:26 GMT + 0000 2008»

    I want to format the date so that it displays only the year, month and date so in DDD/MMM/YYYY format. For this I use a dateFormatter in the Datagrid column advanced in the following way:

    < mx:AdvancedDataGridColumn headerText = "PriceDate" width = "240" dataField = "priceDate" >
    < mx:formatter >
    < mx:DateFormatter formatString = "DD/MMM/YYYY" / >
    < / mx:formatter >
    < / mx:AdvancedDataGridColumn >


    I of course expect to see "March 19, 2008", but instead, I get "19 March 2000".»

    If you can solve it for me or suggest another way, it would be much appreciated.

    Best regards

    This was solved by using the labelfunction property instead. I don't know why, using a DateFormatter in the Advanceddatagridcolumn has failed - it looks like a bug.

    But the solution is to have the datagridcolumn as:

    and have a DateFormatter on its own in the mxml as in:


    labelFunction = "date_labelFunc" / >

    and the labelfunction should look like:

    private void date_labelFunc(item:Object,_column:AdvancedDataGridColumn):String {}
    Return dateFormatter.format (item.priceDate);
    }

  • 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.

    You do this too complicated. Use an editable DataGrid. Do not use a custom itemRenderer. Value editable = "true" on the data grid and any column you want to change.

    Loop by using the function I posted. Everything will work as desired.

    Tracy

  • output of Get-store data in the table (datagrid)

    Hello

    I'm trying to get the output of get-store data in a table (datagrid).

    Code:

    Function Get-data warehouses
    {
    $array = new System.Collections.ArrayList object
    $Script: GetDatastore = Get-Datastore
    $array. AddRange ($GetDatastore)
    $dataGrid1.DataSource = $array
    $form1.refresh)
    }

    error:

    Das Argument '0' mit dem Wert "local_datastore01" as "AddRange' nicht den Typ"System.Collections.ICollection"konvertiert werden kann:" Der Wert "local_datastore01" vom Typ VMware.VimAutomation.Cl «»»
    ient20. DatastoreImpl' nicht den Typ "System.Collections.ICollection" konvertiert werden kann. »
    -snip-
    + $array. AddRange < < < < ($GetDatastore)
    + CategoryInfo: NotSpecified: (:)) [], MethodException)
    + FullyQualifiedErrorId: MethodArgumentConversionInvalidCastArgument

    Comment:

    If I replace the query data get store-get - VM the script works great!

    What's wrong? any suggestions?

    Many thanks and greetings

    Hello

    This particular Get-Datastore call returns a single object, which cannot be converted to the ICollection. But you can do something like this:

    If ($GetDatastore-[table]) {}

    $array. AddRange ($GetDatastore)

    } else {}

    $array. Add ($GetDatastore)

    }

    It will manage both situations - when you get the data object store or table of data warehouses.

  • Advanced DataGrid - converters - Possible to reference the columnIndex parameter?

    When you work with AdvancedDataGridRendererProvider in an advanced Datagrid - is - it is possible for the rendering code reference the AdvancedDataGridRendererProvider columnIndex parameter?

    Thank you.

    I have attached two examples that use the AdvancedDataGridListData properties so that they can be reused in different columns. The first is an example MXML which extends canvas and uses bindings to set the text and tooltip on a Label control. The second provides similar functionality in ActionScript by extending UIComponent. The ToolTip displays some of the information that is accessible through the AdvancedDataGridListData object.

    The AdvancedDataGrid will inject an AdvancedDataGridListData instance in any element converter that implements the IDropInListItemRenderer interface. To implement this interface that you use the 'implements' keyword when you declare the class and add getters and setters for the listData property. I did it for each converter in the example.

    Simpler example MXML, the ActionScript example should perform better.

  • ToolTip in advanced Datagrid

    Hai

    I need to display the text in the ToolTip in advanced datagrid

    The values will be dynamic, the string will have the space and values of next line...

    How display all this in a tool tip in flex.

    I have more than 4,000 characters.

    Can someone help me

    Thanks in advance

    You can define showDataTips = "true" on the AdvancedDataGridColumn for columns on which you want to display the DataTip.

    Also, he must put the dataTipField on the example of AdvancedDataGridfor:

    myAdvancedGrid.dataTipField = "app_desc";

    Thank you

  • 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 get the filtered data from the first form

    How can I get the filtered data from the first form in a second form to make an update of the multi.
    Thank you very much

    William,

    I would use for this collections. A link is good if you need to pass a single value.

    1. create a collection
    2 fill the collection with your result set
    3. go in the page target and uses a method of a query in your link to this page
    4. your target page receives a request and allows you to edit documents.
