Flex DataGrid Shows Mixed Data?
Dec 14, 2011i've working in flex for some years and it seems to me it's an awesome tool. Some days ago i've had an extrange behavior in my datagrid.
I have a php service which reads a database and sends this data to felx. The service and the info saved in the dataprovider in flex are working without problems, but when datagrid shows the loaded info, it shows many cells with wrong data. The data shown seem to be mixed with other cells. I have two registers: "The lightbulb is red" and "The dog is dangerous". But the datagrid shows e.g. "The lightbulb is Dangerous" or "The dog is red". When i see the dataprovider in a breakpoint all data is correct.
But it's even much strange when I click over a problematic cell, this automaticaly changes its content to correct values.

Dec 11, 2009I have a custom ActionScript class:

And I want to bind these values to textBoxes, so that when user types information to the textBoxes it is populated in the class too. Is Flex 3 bidirectional so that marking the class with [Bindable] I can bind the values to a textbox for example?This is my mxml file in which I try to bind the class:

The flex compiler shows me this kind of warnings: Data binding will not be able to detect assignments to "company".
Flex :: Any Way To Scroll Datagrid On Timer Basis
Aug 20, 2009Is there any way to scroll Datagrid on timer basis.Let say there are plenty of records which can not be shown in one screen. And the screen is showing the first 10 records. An auto scroll should start after 5 seconds and bring up the next 10 records. Then again after 5 seconds the other 10 records and so on. A kind slide show effect.
View 1 RepliesActionscript 3 :: Force Flex Datagrid To Scroll
Dec 15, 2009Is there a way to make the datagrid scroll if it's width exceeds it's parent container (instead of making the parent container scroll?) I have a datagrid with a fixed column, and of course I want the scrollbar to appear for the datagrid and not the enclosing HBox. I already set minWidth of the HBox to 0, tried autoLayout=false, but with no effects. The datagrid is dynamically created in AS3, so the enclosing container.
Maybe I did not express my needs clearly - the content of the datagrid should not be wider than the datagrid itself. I just want to surrounding Canvas of the Datagrid to not have any scrollbars and let the datagrid itself scroll. But just setting the scrollpolicy to off on the Canvas will not yield to scrollbars on the datagrid, it will rather clip the data.
Flex :: Keep DataGrid In Same Scroll Position After Update?
Sep 8, 2010I have a custom <mx:DataGrid /> that is updated with data from a ColdFusion server every 60 seconds. I've noticed that every time the DataGrid updates and redraws the scroll position is reset to the top.
Is there a way I can preserve the scroll position for my DataGrid?
Flex :: Actionscript 3 - Making A DataGrid Scroll Smoothly?
Dec 2, 2009I've noticed that the default behaviour for a DataGrid's vertical scroll bar is to scroll one row at a time. This is all well and good when the rows are all uniform and small (e.g. displaying a single line of text), but gets really ugly as soon as you have rows with variable heights.I'm curious, is there a way to make DataGrid scrolling "smooth"? For instance, is there a way to have the DataGrid scroll by a set number of pixels, lines of text, etc. rather than scrolling one row at a time?
So far, the only solution I've managed to come up with is to place the DataGrid in a Canvas and have the Canvas do the scrolling instead of the DataGrid. The issue with this approach, though, is that as soon as the Canvas scrolls far enough, the DataGrid headers scroll off-screen. Ideally, I'd like to get the smooth-scrolling nature of the Canvas, but also keep the DataGrid headers visible.
Actionscript :: Scroll The Datagrid Down Or Up To Selected Index Row Flex?
Jul 7, 2011I am performing a find operation in a datagrid on one of the columns. After I find the row containing the item, I make that as the selected index row, which highlights it. But now I also want to scroll the datagrid down or up (if the item is out of screen scope) to show that selected item automatically on this find operation.
View 1 RepliesFlex :: Get A Custom ItemRenderer To Scroll The DataGrid Rather Than Its Cell?
Jun 2, 2009I'm having an issue with a custom ItemRenderer I've written for a DataGrid. With this ItemRenderer, it's possible that the contents could exceed the width and height of the DataGrid cell - and when this happens, scroll bars appear, letting me scroll the individual cell.What I would like, however, is that when the contents of the cell are too large, the entire DataGrid scrolls, rather than the individual cells.
Now, when I set the custom ItemRenderer's horizontal and vertical scroll bar policies to "off", I get the vertical scrolling on the DataGrid that I want (the individual cells stretch to accommodate the full height of the contents) but I don't get any horizontal scrolling. Instead, any content too wide for the cell is clipped. Incidentally, setting the DataGrid's horizontal scroll bar policy to "on" has no effect, the scroll bar gutter is drawn, but nothing scrolls Is there a way to force the DataGrid to scroll horizontally when my custom ItemRenderer's contents are too wide for the cell?
Flex :: ComboBox In DataGrid Loses Values When Scroll Horizontally
Dec 14, 2009I have a very strange problem in a Flex 3.4 Datagrid. One of the columns is a ComboBox - I have my own custom renderer for the ComboBox. I use it to select my data and then make a "save" to the db. Upon return the comboBox loses its value. Even stranger is that when I scroll the datagrid area to the left (by moving scrollbar right) - the values in the ComboBox change!! When I scroll the datagrid right (by moving the scrollbar left) - the values in the ComboBox don't change.

Apr 23, 2011I have a spark datagrid with selectionMode="multipleRows".
I have three columns in the datagrid. I don't want the row selection to happen when the user's click falls on the third column of a row.

There is a selectionChanging event for the datagrid, but the GridSelectionEvent object received in the handler does not seem to provide any information about the column on which the click happened.
Flex :: DataGrid Item Editor - DropDownList Fires Focus Out On Scroll
Feb 24, 2011I have a data grid with a custom item editor that displays a DropDownList component.

Dec 15, 2011I have a spark datagrid on a mobile application, I set the

ActionScript 3.0 :: Scroll Bars Shows Up But The Slider Inside Doesn't ?

I uploaded it to my server to test it and the text shows up but I can't scroll it, the bar shows up but the slider inside doesn't. I don't get any error messages from my browser either.

View 4 RepliesActionScript 3.0 :: Auto-scroll DataGrid Content When Dragging A Row?
Nov 30, 2007autoscroll functionality in Flex2's DataGrid while dragging an element row in it. Is there such a functionality or not?
I mean, I have a DataGrid which contains a collection of rows. The collection is longer that the DataGrid could fit, hence there is a vertical scrollbar that allows to get to the rest of rows. I have enabled the functionality of moving-by-draging to be able to change the order of rows in the DataGrid (see the simple code below).
Now, let's say I want to move the first (topmost) row to the last (bottom) position of the collection. When the top row is displayed, the bottom one is not visible (not without moving the scrollbar). So when I drag the top row, I cannot drop it beyond the few currently visible rows. Surely I could drag a bit and then scroll to bottom and then drag a bit more, but that's not the point. The point is - is there a functionality of autoscroll implemented in Flex2 DataGrid, where the collection would scroll itself automatically to allow one to drag beyond the few visible rows?
In Adobe's official PDF document "Flex2 Developer's Guide", section "Using drag-and-drop with list-based controls" I've found this sentence:
Quote:
If the control has active scroll bars, hovering the mouse pointer over the controls top or bottom scrolls the contents.
Well, it suggests that there should be this functionality I ask about. But it doesn't work for me.
Here's the simple code that builds the DataGrid in Flex2, that fails to autoscroll, if you care to check it:

Actionscript 3 :: Scroll Bar To Appear When The Content Is Too Tall, And Have The Same Skin For The Background As The DataGrid?
May 16, 2011I'm trying to create a layout not too different from the feed reader sample.The problem I'm having is that I'm finding the documentation unclear. There are so many different types of layouts that I don't know which one to use when.In the example, on the right side there are a few horizontal panels:
[feedToolbar(HboxPane)]
[feedItemsGrid(Datagrid)]
[filterToolbar(HBox)]
this does not include the details panel and the resize handle.I would like to swap the DataGrid with my custom content which is basically a sprite. The problem I have is that I cannot just include a sprite, because it does some funky resizing. I would like the scroll bar to appear when the content is too tall, and have have the same skin for the background as the DataGrid.

View 1 RepliesFlex :: Datagrid Selects The Wrong Custom Cell In Datagrid
Mar 15, 2010I am working on a problem since a week soon, but I still couldn't make it work as expected. I have a DataGrid which has HBox with a CheckBox an a Label as itemRenderer (see Code below). When I tap in to the Cell the standard itemEditor pops up and lets you enter the content of the label. Thats the standard behavior. I works fine except for 2 problems:
If I enter to much text, the horizontal srollbar pops up, and the cell is filled with that scrollbar. As you see I tried to set the horizontalScrollPolicy to off, but that doesnt work at all... I tried to do that for all the different elements, but the failure is still existent. When I have filled more than one row, there is an other mistake happening. If I tap on a row, the datagrid selects the one below that row. That's only if one line is already selected. If I tap outside the datagrid and then, tap at any row the itemEditor of the right row will show up... Is there anything now wright in the setup of my set data method?
