Flex :: Datagrid, Select An Item Given My Data Attribute Values?
May 6, 2010
I'm using a custom component CheckBoxList DataGrid (http://blogs.adobe.com/aharui/2008/02/checkbox_selection_in_datagrid.html) and as dataProvider I have an ArrayCollection with items such this one:
name="item name" selected="true"
I would like the CheckBox list updated when the selected attribute is set to false or true in the data model.
What I want to do is, when I select an item in the datagrid, the selected item of the dropdown should be the correct one (the one which has the field idCompSuperioara equal to the third element in the selected datagrid row).
I've a custom itemRenderer for my datagrid. To set the actual data I use the following method:
override public function set data(side:Object):void{ ... }
As soon as I use this function the cell doesn't show up any item Editor anymore. Why is that? When I remove this function the itemEditor is working but with the wrong initialization data.
In my flex datagird i have a checkbox and a datgrid with seven columns. im populating values in first five column(remaining two column no values) of datgrid by an Arraycollection. now,By clicking the checkbox i want to show all seven column values and if i uncheck five columns has to show... how its possible?? heres my code
group items in a DataGrid by an item property, fer example:Say you have a list of products, and the products belong to categories, like, Summer products, Winter products...is there anyway to group products in a DataGrid under separate headers? IE: Winter (all winter products follow) Summer (all summer products follow). I can already order by category, but instead I want to do this:
Do it need to create a DataGrid for categories and nested DataGrids for products per Category? Or is there some built-in way of grouping within a DataGrid?
I'm trying to get this code working: <mx:DataGrid x="359" y="221" width="623" height="176"> <mx:dataProvider> <fx:Object name="Garbage Collection" code="7777" hours="2"/> <fx:Object name="Road Repair" code="8888" hours="6"/> <fx:Object name="Lawn Maintenance" code="9999" hours="12"/> [Code] ..... I even don't have the header text in my columns.
In Flex 4, I have a Spark List component with item renderers. I would like to select an item in the List by clicking on it, and deselect it also, by clicking on the same selected item. Like an on/off switch.
In a flex datagrid, by default clicking on column headers does sorting. I want it such that if a user clicks a column header the entire column is selected. I have the datagrid listening for the HEADER_RELEASE event so I know when the column header is clicked.
How can I have the column and header appear highlighted similar to how a row is highlighted when selected?
I have a datagrid. How can I put the focus on a particular row (ie row #5) of a datagrid via actionscript? I'm partially there, but not quite: stage.focus = myDG; This obviously just sets the focus to the datagrid and not the row.
I have button like random click ,if i click this button then will select 15 checkbox within datagrid itemrenderer checkbox But i can't access the checkbox ? please refer me ? How can access the checkbox ?
i want to unselct checkAll checkbox when i deselect any of row checkbox,i am trying to access value of checkAll to check_clickHandler(), but i am not getting its value.
I want to be able to select an item from my list component and fire a function directly related to selecting that item. list is called "tidlist" function is "selecttid(n)" the "n" needs to be replaced with the index number... so if run my swf and the list component displays my items... when i select one (the third one for example)... i want to fire "selectTid(3)".... cant seem to grasp.

The selectedIndex is associated with an HSlider, but that is not the problem. My issue is that I would like to automatically select a certain "preferred" element from the list (only initially...to guide the user).
I tried to do that in a creationComplete event but my data hadn't shown up yet...setting selectedIndex didn't work..
I have an xml with an xml-schema. The xml-schema defines an abstract complex type with 2 optional attributes that have default values. Then I have several complex types that extend the base one. And finally nodes of the types defined.So I load the xml and when I parse each node, the optional attributes are not present at all.I've tried fooling around with the namespaces, even[code]...
No luck. Something similar was being experienced by this guy on codingforums, but that was like 5 years ago. Same is happening to me with firefox 3.0.11 - the xml is shown without the default attributes.For now I'm setting the default values in code, but isn't there a way to make them available from the xml-schema?[code]...
I have a datgrid with two inline item renderers. The dataprovider for my DG is a nested object (objects within objects within objects i.e 3-layered). Main Object - 1st Level
[Code].....
I use 2 item renderers (one for each datagrid column) which loops thro the 2nd level object1 and 2 respectively (the 2nd level object is a dynamic array of objects, in that the number of objects within keep changing). Within the item renderer I loop thro the 2nd level object using a foreach and then display the data. The data is a linkbutton, which when clicked , calls a remote object function to delete the data from the database
now on the result event of the remote object function call, i call the function to repopulate the DG, so that the updated data is displayed. When i click on the linkbutton in the first row, the backend works perfectly fine (the data gets deleted from the database and the refreshed data is sent back), but for some reason, the deleted data suddenly appears in the 2nd row. When i delete it from the second row, it appears on the 3rd row (nothing happens in the backend since the data is already deleted).. and so on, till it appears on the last row and then the DG looks exactly the way it shld have looked after the first delete.
This is just the beginning. The second item renderer also displays a linkbutton, which when clicked, displays that data in the previous column (the one where this data can be deleted). When i click on 1st row, the data gets added in the previous column of the second row. and so on.. Basically, my DG is acting really weird. I overrided the set data function in the item renderer to refrsh the data and called its invalidateDisplayList. I also call the Datagrid's invalidateDisplayList function after each refresh. The behavior remains the same.
I am trying to bind a datagrid item to a combox, so that when the user selects the item in the datagrid the form displays the selected data for editing, however one of my items is a combobox using a dataprovider.
I would like the item selected in the datagrid to match the selected item in the combobox, this part is fine however if my datagrid item is null then I cannot get the combox to set the selected index to -1?(the same happens if you use the CRUD wizard in Flex builder 3 for ColdFusion)I am using the following code for my custom combobox:
