Flash :: Flex AdvancedDataGrid Not Populating Properly?
Jan 11, 2012
I'm having trouble getting an AdvancedDataGrid to populate properly within an app I'm working on.If I use the sample code found on this page http:[url].... in it's own page everything works fine but if I copy this code into the page within my app that needs to have the grid the column headers/data are not populated.The page that needs the grid is displayed within a Spark NavigatorContent element, I'm not sure if this could somehow adversely effect the AdvancedDataGrid behaviour.I've even simplified the contained page to have just the sample code without anything else and it still does not work. info needed here,
EDIT: Some code sample from the project:
//Code from 'main page' containing the NavigatorContent
<mx:ViewStack id="viewstack1" cornerRadius="12" dropShadowVisible="false">
<s:NavigatorContent label="Matrix View" backgroundColor="#FFFFFF">[code]...............
I have an advanced data grid in flex (flash builder 4). It's dataProvider is pointing to an ArrayCollection (this._encounters). Inside that array collection is a property that is an object (a client object).
I tried setting the dataField to "clientObj.firstName" to refer to the first name property within the clientObj property of the this._encounters array collection. It did not show anything. So, I added a labelFunction to that column (code below) to set the text in the cell. This works fine and now I have values showing in the grid.
The problem is now when I click the title of column to sort it. It throws an error that property clientObj.firstName is not found in my array collection!So, is there a better way to set the dataField / source for a column and point at a property in a sub-object -- or a way to fix the sort?
I have some rich text created using the flex (flash builder 4) rich text input control. I want to display at least some of it in a column of an AdvancedDataGrid control.
I am creating a RSS Feed application based on a data, and I have the following:
I have an ArrayCollection that is pre-populated with data. I am sorting through the ArrayCollection, get 1 piece of data (condition), and need to connect to an RSS feed which returns me the title, and I set my ArrayCollection in correspondence to condition -> title.
public function updateArrayList(list:ArrayCollection):ArrayCollection { trace(list); for(var i:int = 0; i < list.length; i++) { //Alert.show(list.getItemAt(i).condition);
where the component before / represents parent and the children of the corresponding parent are separated by , Can anyone provide me the logic to create a array collection for this hierarchy to set as dataprovider to my tree.
In the below code.If buttom 'A' is pressed the text box should be populated with A, and if button 'B' is pressed it should be populated with B and so on..
What is the best way to populate a multiple Comboboxes when using Flex 4.5 and PHP 5?
I am developing a Flex app that displays about 20 Comboboxes on the screen - each combo showing different data. I would like all of the comboboxes to be populated at once when the app starts. I used the default "Data/Service" wizard in Flex that automatically creates the PHP that returns an ArrayCollection to Flex. For example, below is the current PHP function I use that populates each ComboBox:
public function getListsByCODE($code) { $stmt = mysqli_prepare($this->connection, "SELECT a.IDCODE, a.CODE, a.DESCR, a.NOTES FROM DROPDOWN_VW a WHERE (a.CODE = ?)"); $this->throwExceptionOnError();
I'm using Flex 4 and I need to render the data that resembles HTML Table with row span in a Flex component.My inclination was to use a DataGrid but I believe that rowSpan is not supported for that component. I looked at the AdvancedDataGrid but the user does not want to have a tree-structure in any of the columns. Looking to see if there are any hints/tips for modifying the DataGrid or AdvancedDataGrid to produce an "HTML Table with rowspan" look.
I have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.
I'm having a problem displaying data from a function to text box within a tab. If you run the code and click "Select Tab 2 and Fill..." I get an error; "TypeError: Error #1009: Cannot access a property or method of a null object reference." I'm guessing this is because "Tab 2" is/was not rendered yet. Now if I run the code, select "Tab 2" then select "Tab 1" and click "Select Tab 2 and Fill..." it works the way I would like. Dose any one know a way around this problem.
I am passing a complex object from my .NET library to my Flex application via WebOrb.In order to automatically translate, I am using the [RemoteClass] meta data tag as follows:[code]This works absolutely fine, until I try to extend the Plan class to contain an array of complex items:[code]but the set function never gets called.What can I do to get the children into my Flex app in this way?
I only need the Title and Updated fields to actually be loaded into the DataGrid. This clearly doesn't work, (I think it's related to result.entry, that it must be something else like result.feed.entry, but I've tried a number of combinations and they haven't worked
Is there any way to detect if AdvancedDataGrid itemClick event is actually caused by the user dragging? I'd like to take action on click, but ignore drag.
In ActionScript I have string as str="subject,r1,r2:a,b:1,2:3,4"; Dynamically I have split this string and build array collection as given below arraycoll.addItem({subject:a ,r1:1,r2:3}); This example of one set. The array collection should be built dynamic. I have tried but not successful.
I have an AdvancedDatagrid, whose dataProvider is an ArrayCollection that contains 1 row of displayable stuff.Flex continues to display about 6 rows, the top one filled, the rest blank.I've set the rowCount="1", with no luck.
after multiple Selection in a advanced datagrid, I want to check if the clicked row, was already selected. Anyway my idea below (in the nested if clause I want to check if the newly clicked item's processing data is already in the added Array Collection) is not working, but I assume there must be a better way to differiante if an click was made on a already selected row.
model.processingData = out; if (model.selectedIndices.length > 1){ //check if item already added
I would like to add new row on the fly (runtime) to my AdvancedDataGrid.I can add it to the data model, but couldn't find a way to make the table render and show the new row.What i am seeking for is to create an effect of expandable item, where clicking on row will show "additional information" (like a drawer) and clicking on row expand button will reveal it's children.I saw examples of this for dataGrid (http:url...), but not for AdavancedDataGrid.Only way I found to do this is to add a new child and use openItem, but this cause the other children to be visible as well.
I've got a subclass of AdvancedDataGrid showing a tree-like data structure. How can I, given the index returned by calculateDropIndex, get the item at that index? After reading through reams of code, it seems like the least terrible way is:
var oldSelectedIndex:int = this.selectedIndex; var mouseOverIndex:int = this.calculateDropIndex(event); this.selectedItem = mouseOverIndex; var item:* = this.selectedItem; this.selectedIndex = oldSelectedIndex;
The other option seems to be tinkering around with the iterator property... But, judging by the way I've seen it used, that will get pretty harry pretty quickly too. So, how can I get the item at a particular index in an advanced datagrid without going insane?
Is it possible to use a renderer for for a treecolumn in an advanceddatagrid and still keep the hierarchal functionality? If I use a renderer provider I lose the the arrow for the tree dropdown. I want to keep the tree functionality and change the display of the column.(and not just the folder image)
I've a problem, I'm using an AdvancedDataGrid. It loads about 3000 records with about 20 columns. I constantly get Flex execution timeout because the grid executes a lot inside LayoutManager. How can I make it asyncronousely or faster at all?
how to query an ADG (or its rows) to figure out how many rows are currently visible (i.e. not collapsed) when displaying different levels of a hierarchical collection?In other words I'd like a function that tells me that 7 lines are visible in this view and 1 line is available in this one.
I'm making an application where I display an AdvanvedDataGrid with one column with dates(in format DD/MM/YYYY) and another with datetimes (in format HH:MM). I'd like to sort dates according with the datetimes as well(just clicking in the header of the column), there is an examplen of the expected behaviour:
I am using an AdvancedDataGrid with some hierarchical data. In the first column, I want to indicate whether or not the "name" field is editable by graying out the text for the "name" property of my objects. It's very odd, but when I set the AdvancedDataGridColumn's dataField property to "name", and have it in the first column, it seems to completely ignore my inline ItemRenderer. If I change the dataField property to something else, or change the column ordering so the Name column isn't first, everything suddenly works.
Let me know if any more code would help, but here is the simple ItemRenderer I'm trying to use in the first column:
I am using in-built sort functionality provided by AdvancedDatagrid.I have multiple columns and suppose I have 10 rows. All 10 rows have the same data in one column.If I sort on that column, then it sorts and the data in other columns which is different is also being sorted (reshuffled).My requirement is if I am sorting on a column with same data, it should not sort the data in other columns.To understand it better, check the link menioned below URL...In the above link mentioned, if you click on region column, other columns like territory or actual will change the values i.e. the rows gets reshuffled.This should not happen as we are sorting on a column which has same values. Does anybody know how this can be handled in Flex 3 for AdvancedDataGrid.
