I have a flex grid where I have the verticalScrollPolicy="auto".But every time when the scrollbar appears all the columns get pushed to the left, making the columns not align as they should. I tried setting minWidth on all the columns to prevent this,
View 1 RepliesIs it possible to control the properties of 'advancedgridcolumns' in 'advanceddatagrid' mxml tag. For e.g. suppose the grid data provider has 3 different fields. Out of these 3 fields, one field is 'to_be_decided'. This field should not be displayed initially. Only the remaining 2 columns should be displayed (visible true) and the third column (one with data field as 'to_be_decided', visible flag will be false here ) should be hidden. It will be visible when some event like a button click or something is fired.
We can do this in action script coding by accessing individual columns of grid and taking appropriate actions. But will it be possible to do so in mxml? Is there some default property in grid that can be used here ?In mxml I can not access them individually in the grid (under tag) and hence I can not set the visible attributes individually for each of them. To add them one by one in 'columns' tags I would be required to know the data field in array collection and that I dont know. Only data field known is 'to_be_decided', rest two fields will vary time to time. Therefore even if I addd this one gridcolumn in 'columns' tag what about the other two?
Something like this :
<mx:columns>
<mx:AdvancedDataGridColumns dataField='to_be_decided' visible=false>
<!-- How to add other 2 columns here ? -->
</mx:columns>
I want to some how control the visibility of some columns in my advance data grid. I have a data provider with 115 coumns out of which I want to hide few columns. I know the column index and header field of these columns. Is there some property in Advance data grid where I can specify this directly?
View 1 RepliesCreated an editable flex grid which exposes a method called getGridData() to javascript. I am using the JSON.encode() method of the [url]....library to convert the grid object's dataProvider into JSON before returning it.
ExternalInterface.addCallback("getGridData", getGridData);
public function getGridData():String

However, when I sort a column in the user interface, the encode method is failing throwing the following error
Property usingCustomCompareFunction not found on mx.collections.SortField and there is no default value.
im trying to get a movieclip to move by pushing either the left or right button, and then when the enter button is pushed i want the mc to keep moving but it seems to stay still. this is what ive got so far:
ActionScript Code:
mcBoat.onEnterFrame = function()
{
if (Key.isDown(Key.RIGHT) )
[Code].....
it keeps moving if the enter button is pushed and then pushing an arrow key but not the other way.
I want to save remotely (on a database) the state (visible columns, columns width and order) of a Flex3 DataGrid.For width and visibility I can simply save them by accessing each column attribute.. But for the order? Do I have to create the dataGrid dynamically?

I have a file that I cannot tweak a small fix for the life of me, and I know it is something relatively simple. I've looked at it so long, that I can no longer think! Hate those days...Anyways, it's in regards to a simple scrollbar moving left to right. My button seems to be sticking to my mouse on release, although I put a stopDrag on it. I think I did some of this code backward, but it still works somehow; although I can't explain it. the numbers in parenthesis/minus sign are representing in the following code (in red)? I think I'm looking at this wrong, which is why I am working backward. I need a refresher here as it's been a while since I did one of these.
// have the button interact with the scrollbar button (this is on the ScrollMC)
onClipEvent(enterFrame){
_root.vPosition = _root.SliderMC.ButtonSliderMC._x * (800 / 390) - 200;

i've done the fading grid tutorial at: [URL], but i was wondering if someone knew how to make the grid fade in diagonally from the left or right top corners (or bottom corners too) like this site [URL] i also have another question with the fading grid, does anyone know how to make the grid fade in from random spots on the movie clip instead of the left to right, up to down, etc. way?? i'd really like to see that effect happen, if possible.
View 9 RepliesI rearranged a vertical scrollbar code to get a horizontal scrollbar. The only problem is that now it takes the x coordinate of the last thumbnail (I think) and goes right to left, meaning that the 1st thumbnail will not be at x=0.How can I get it to start with the first thumbnail is at x=0 and go from left to right?
View 5 RepliesI'm currently working with the OLAPDataGrid component and got stuck at a relatively simple task: I want to style the last row of the grid differently from the rest, so my cell item renderer needs to know whether he's rendering the last row with content in the overall grid, including those rows currently not rendered because they are outside the visible grid space. AdvancedGridListData's rowIndex property only gets me the row index of the renderer relative to the range of visible grid rows, i.e. when I scroll down the grid, a data item with an index greater than 0 gets the rpw index = 0.

View 2 RepliesI'm getting occasional ConcurrencyError faults when using HTTPService in Flex 3. I have four HTTPService objects, all configured with concurrency=single. I'm not sure though how to continue to diagnose, as I don't see in the FaultEvent what service object caused the issue, and I can't easily reproduce it on-demand.
One feature of my app is that I am also using a URLRequest to load a sound shortly after receiving a result from one of the HTTPService calls. Could this be related to the concurrency error?
The fault looks like this:
[FaultEvent fault=[RPC Fault faultString="Attempt to invoke while another call is pending. Either change concurrency options or avoid multiple calls." faultCode="ConcurrencyError" faultDetail="null"] messageId=null type="fault" bubbles=false cancelable=true eventPhase=2]
After upgrading the Flex SDK from 3.1 to any newer version of the SDK and trying to compile an existing project, the following error appears in the Problems pane:

I have a streaming server (for pushing data not video) setup with GraniteDS and it works great. I have to include multiple swf files in a web page. Each of these swf files has a data table which includes streaming data(this is a specific requirement - so I really cant combine all data tables into 1 huge data table/swf file). All the swf files however, connect to the same gravity channel/streaming endpoint.
How many connections are there from the web page to the streaming server? Does each swf file start a new streaming connection? Or do all them share the same connection since they are just connecting to a single channel?
I have a datagrid which has id="myGrid" in my application, from it I call a component.

I have a problem with inline components. I want to reach an inline component from another one.. From the first component, i want to change "enable" value of the linkbutton named "Add" which is in second component. Altough i gave "id" and "className" to second one, i could reach neither it nor its elements.. is there a way to do this?
*in first component there is a text input in "CodedDescriptionItemEditor" component. I want to validate it and according to validation enable the button that i mentioned above..These all are in a datagrid by the way. In datagrid, there is always a row that you can enter data and via the "Add" button you can save it. After save it seems as text..

View 1 RepliesIn Flex3, I could compile pure as3 code and use "embed" tags to load in images. This was done by Flex making a BitmapAsset class.I can still do this in Flex4.
However, there was a trick to fakeout flex3 and use my own mx.core.BitmapAsset class to remove some of the extraneous stuff Flex's BitmapAsset brings in with it. This is described here: [URL]..Unfortunately, I cannot get these tricks to work with Flex4 and get smaller file sizes. I end up with the error "VerifyError: Error #1014: Class mx.core::BitmapAsset could not be found."[URL]..Following this advice, I add -static-link-runtime-shared-libraries=true, and my swf loads without an error... but this means I am loading in the pieces of the flex framework I wanted to omit (and the file size says so too).
Is there a better way to fake out flex4 when it comes to using Embed?
