Actionscript 3 :: Persist Row Order In Flex AdvancedDataGrid
Sep 30, 2009
I have an AdvancedDataGrid that I allow the user to drag/drog the rows to reorder them and also allow them to sort on columns. I want to save the row ordering so that the next time I load up the data, the row ordering is preserved.
I have a bindable array collection to the data grid. The array is a collection of a custom AS object. I tried just using the bindabled array collection I give to the datagrid but the order always stays the same.
Is it possible to persist the look of a 'hovered' hyperlink even after the mouse has moved away from it? I want to keep the user's attention on the hyperlink -- or at least have them able to see what it was, standing out from the rest of the text -- for a few seconds after they've left it. Ideally it would fade slowly back to normal
I built a simple hello world app to check out the Flash Builder 4.5 mobile capabilities.Here's how it works:The Default View asks for name in an textinput and has a continue button.When you click the continue button it pushes a new view in the viewNavigator which just displays "Hello " + name in a label.When you click anywhere in this view, it pops a view (i.e. itself) from the viewNavigator, to go back to the default view
I see only 1 issue with this:When I get back to the default view, it is in its initial state, i.e. the textInput is blank. It seems as if the viewNavigator created a new view of the default view's class and pushed this, instead of just removing the top view and displaying the previous one.I see this being especially problematic for programs which display data in a grid and you can click the data to view the detail...when you get back, the grid will be empty.
Does anyone know if adobe flash player cache data is available to other users on a system? For example: A user logs onto Windows XP, then uses my adobe flex application... and in the process of doing so downloads the signed flex lib... He then decides to mow the lawn and log off. At about 3pm the same day, his Mum can't hear the TV over the sound of the mower, so she decides to log in using a different XP user account. She proceeds to use the very same flex application. Does she also need to download the flex lib again, or would the data already be cached in the flash player?
I'm interested in building a thick client application for my existing web services that will run on the IPhone. Flash finally seems to be an option, so I thought about using Flex for client side development.
However, since flash apps are not natively supported by the IPhone, but only through a wrapper, I was wondering if these apps can persist any data. Data entered by the user should eventually be transmitted to the web service, but until then I want it to persist even if the Iphone should run out of power.
Is this possible? Or does the Iphone flash wrapper make it impossible to access the hard disk?
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.
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.
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.
I'd like to implement a custom drag on an AdvancedDataGrid tree structure, which only allows the drag on the branches (not leaves).I'm having much difficultly with this, trying to use the MouseDown event, but not having luck! I think I've got the mousedown able to figure out if the item is a branch of leaf. Any help on how to perform the custom drag with an advanceddatagrid?? [code]
How do I determine which Flex AdvancedDataGrid cell - row and column index - I've just dropped onto? calculateDropIndex seems to give me the row, but how do I get the column?
I have a advancedDatagrid with column headers having input text boxes for filtering.The column is filtered according to input text when I use characters as data inside that column.But when I use numbers in the column field,filtering does not happen.Can anyone tell me what went wrong.
I want to extend AdvancedDataGrid to show a Waterfall Chart in one of its columns.
To do that I already created custom cell render that shows bars as I need.
Now I have a little challenge: I have to pre-process data to show my Waterfall Chart properly. I have to do it before my grid is show. So, I assume that I have to extends AdvancedDataGrid and overwrite some methods.
I'm using an AdvancedDataGrid without the header row (AdvancedDataGrid.showHeaders="false"), my AdvancedDataGrid has 2 columns, where the first one will show a hierarchical data (tree).The tree may be very long and very deep or may contain a long string in the node label so the user will not be able to see the whole vale of the tree node, I want to be able to resize the column using the vertical separator of the gris (the one displayed/separates between columns) or to be able to define a horizontal scroll bar only for the first column.
