• How do I scroll a datagrid control, so that a column is visible?

  People,

  I have a DataGrid that contains a large number of columns.  I went on a horizontal scrolling, so I can now scroll horizontally across the table to my desired location.  What I want to achieve now is the ability to scroll the table programmatically so that a column is visible.  Anyone has any advice or revenue as to how this could be achieved (if any)?

  Thanks in advance.

  Neil

  Must be:

  dataGrid.horizontalScrollPosition = Math.min (desiredColumnIndex, dataGrid.maxHorizontalScrollPosition)

• Support TLS 1.2 Air Desktop Version-Flex SDK 4.5.1

  Hi all

  I'm new to this forum. I'm working on the desktop air application. recently of Salesforce announced we'll disable the TLS 1.0 since their servers and they will support the TLS Protocol 1.1,1.2. Here is test url that we can use to test in the Office of the air: https://tls1test.salesforce.com/s/. I went through some of the messages in this forum and have not found similar post about this issue. I found one, but it did not help either: done FLEX and AIR support TLS 1.1 + encryption?  

  
  

  I wrote the code to verify that the url below. SecureSocket connection is successful. but UrlRequest is a failure, because it uses TLS 1.0 version to connect to the server, since Air app uses the TLS 1.0, the handshake protocol is a failure. I found this info in wireshark: TLSv1 Record Layer: alert (level: Fatal, Description: failure of the handshake)

  

  My goal is to spend my desktop client to support TLS 1.2 Protocol. I use the version of the Flex SDK 4.5.1 to build the application. Can you please help me understand this issue?

  1. Is there anyway to set the version of the Protocol TLS for UrlLoader and UrlRequest?
  2. I need a client certificate to authenticate with the server for TLS 1.2 Protocol?
  3. This will work if the upgrade from Flex and Air SDKS, I tried, it doesn't work, but do not know what I have tried is correct or not?

• Flex SDK 4.1 + 'Use the Compatibility Mode 3 Flex' = PROBLEMS

  7.14.10 / 06:10

  HERE'S THE QUESTION:

  When using the Flex SDK 4.1 and by checking the box 'Use Flex 3 Compatibility Mode', the Visual anomalies occur (regardless if the styles or skins is used). These include text in list ComboBox becomes invisible. It goes the same for the alert box, where no text is seen.

  I am including a screenshot showing the questions. The top image shows what happens when compatibility is checked - the ComboBox list text is invisible. The lower picture combo shows what happens when the box is not checked.

  Please note that when you use the old Flex 4.0 SDK these visual anomalies are not and everything works fine.

  

  @Jason Villmer,

  In my view, the problem you describe is http://bugs.adobe.com/jira/browse/SDK-26940.

  There is a workaround solution listed in the bug report that works (based on my tests), or you could probably put the leadership styles and layoutDirection worldwide using a block Style.

• Problem with AdvancedDataGrid in Flex SDK 3.3

  Hello Forum,

  I downloaded and installed Flex SDK 3.3. Once I did my environment for the 3.3 SDK compiler complained that he cannot find the AdvancedDataGrid component in the path. After some research, I was able to solve this problem by downloading Flex 3.3 Data Visualization Components of http://www.adobe.com/products/flex/flexdownloads/. Then I had to unzip the file downloaded in the /sdk_3.3.0_install_dir/

  I don't think that I had to go through that in my previous installations - 3.2 and 3.1. No one knows the reason for this step both download and installation?

  Also, I would use a new class of vector in my future development, anyone know what version of the SDK it provides?

  Much appreciated,

  Mike

  Hi Mike, the two-step process is because the AdvancedDataGrid and graphic elements are not part of the Flex SDK, they are additional components that come along Flex Builder 3 Pro

• Flex Builder error: Namespace 2.6 in the application descriptor file must be equal to or greater than the minimum version 3.1 required by Flex SDK.

  "2.6 Namespace in the application descriptor file must be equal to or greater than the minimum version 3.1 required by the Flex SDK kit."

  what it means?

  to run the application

  (1) I need lower version 3.1

  (2) I need a newer version than the 3.1

  I'm confused.

  You can change the project xml file. I solved like this.

  

• Building Flex SDK

  I have download the Adobe Flex SDK 4.6, modified the DropDownController.as file, run the ant script to generate her updated the SDK.

  I created the Flex with this updated SDK project, but still the old code is reflecting instead of the updated SDK.

  What I am doing wrong.

  (PS: I try to avoid making the monkey patching)

  I think monkey patching is much easier.

  If you use RSL, then your changes will not be in the official RSL and you will need to monkey patch.

  If you are linking static libraries then what you should work even if Flash Builder requires a reboot that it can cache the old SWCs.

• Unknown Flex SDK: «Extension Builder 4.5»

  Hi-

  I investigated this during a few days and I can't find an answer. I have a license Extension Builder 2 and am subscribed creative cloud. My ideal scenario is to build my extension with Fb 4.7. However, this seems so an unsupported configuration...

  My second best option is to build with 4.6:

  I install CS Extension Builder 2.0 in FlashBuilder 4.6.

  Installation seems to fill.

  I build a simple helloworld project.

  I target for SC 6.

  I select run as Adobe Indesign Extension

  I get the error: Unknown Flex SDK: «Extension Builder 4.5»

  Of course, my project is "Extension Builder 4.5" but this SDK is not installed. Or unrecognized. Or...

  Help, please. I encountered this on two separate computers (both mac os 10.8.3) and I am puzzled.

  I solved this. I have redownloaded and installed 4.6 FB.

• Flex sdk 4.1 request show

  My request consists of 4 modules developed in flex sdk 4.0, has clusters of resource (Eng. and Spanish), now, we have designed the 5th module with flex sdk4.1 a eng and bundles of resources, when I

  Compile and run the app (5 modules) whole under unix with sdk4.0environment, each module is loading fine, until the charges of 5 modules, when 5th module loading, for the first time Spanish isn't

  loading, the entire page is empty, when I switch back to English it takes care of everything, and then you click on Spanish it works fine, every time when I change the viewstack the Spanish does not work for the

  first time. I debugged the issue, it gives no error,

  method Intialize() is called, creationcomplete is not called for main component viewstack.

  I changed all the 5 modules for bending sdk4.1 and respected and it works very well without Spanish loading problem.

  My question is their anyway I can use use sdk4.0 and run the application.

  they all matter to develop a module with sdk4.1 and compling it with 4.0?

  Your first message says that you had created the 5th module in a different SDK.  Who is this?

  TO

  Flex_sdk = / Applications/Adobe\ Flash\ Builder\ 4.6/sdks/4.6.0

  2. 02 - create the extension of the platform-> mac-> TestNativeExtension-> TestNativeExtension.xcodeproj

  Open the project in XCode, select the root of the project, and then TARGETS-> TestNativeExtension-> build settings

  change Search-> Search framework paths paths

• Flex assess dynamic string for headerText datagrid

  Hello: I m new on Flex and creates headerText to a datagrid (dgTop250). How can I get the headerStr variable to evaluate properly in the last line of the function? With the code below, I get the entire string as the header of column in the datagrid control, not the evaluated expression that I need. HeaderStr variable evaluates correctly, I just need to evaluated in the headerText statement... I know that the eval function is not available in AS3.

  public function get250(event:ResultEvent):void {
  (var i:int = 0; i <= dgTop250.columnCount; i++) {
    var colName:String=dgTop250.columns[i].dataField;
    var headerStr:String="top250.lastResult.IMS001HQ2.SGM.getItemAt(i)."+colName+".label";
    (dgTop250.columns[i] as DataGridColumn).headerText = headerStr;
  }
}


  For example, this is what I get as a header: top250.lastResult.IMS001HQ2.SGM.getItemAt (i). STOCK.label

  That's what I need: Stock Number

  "Stock Number" is the label STOCK.

  Thank you

  Have you tried all other combinations - I don't want to duplicate your attempts.

  Or can you put more code so I have a try myself here.

  Can try without a point before hooks

  var headerStr:String=top250.lastResult.IMS001HQ2.SGM.getItemAt(i)[colName].label;

• Flex 4 grid data: text Elements can be interactive?

  It is more a question about the possibilities, since I have not used datagrids beyond SQL/PHP data display in the columns.  I already saw that columns can be customized, colorful décor, so I suspect that many other properties can be changed as well.

  Text in a datagrid control can respond to the events of mouse as the text box and other text controls?  Can have ToolTips?  Pop-up windows?  In addition, the text can be formatted as html text?

  Or control datagrid isn't a good match for the display of the "files", but not what I want to do?

  Thank you.

  You must use converters of point for datagrid columns. So you can view the data in any form you want and then you can view ToolTips and other things you want for individual renderers.

• How to disable the elements (gray out) in the DataGrid control?

  Hello

  I need to implement a component custom for a selectable list with a maximum selected items.

  in other words, when the selected items reached the maximum, all unselected items will be gray outside.

  Now I am able to use the DataGrid control to display a selectable (by itemRenderer) "checkbox" to the first column, to let the user select the item.

  And the name of the list in the second column.

  But I can't find a way to grey out (disable) these no selected item when max is reached.

  Can someone give advice?

  Here is my code snippet:

  SelectableListView.mxml

  < mx:VBox ' xmlns:mx = ' http://www.Adobe.com/2006/MXML " " width ="100%" height = "100%" "visible ="true">

  "" " < mx:DataGrid id ="list_datagrid"dataProvider =" {} {this.stringList}"showHeaders ="false"

  "" "" editable = "false" "selectable ="true"verticalGridLines ="false"borderStyle ="No"alternatingItemColors = '[#F8F8F0, #FFFFFF]"

  "" "" left = "5" rowCount ="16" rowHeight = "20" height ="83" width = "100%"top ="0"doubleClickEnabled = "true" doubleClick ="onDoubleClick (event)" >

  < mx:columns >

  " < mx:DataGridColumn id ="listCheckBox_col"dataField ="selected"editable ="false".

  "itemRenderer ="ListRenderer"width ="18"headerText =" ' resizable ="false" draggable = "false"/ > "

  " < mx:DataGridColumn id ="listName_col"dataField ="name" / >

  < / mx:columns >

  < / mx:DataGrid >

  < / mx:VBox >

  ListRenderer.mxml

  < mx:Canvas ' xmlns:mx = ' http://www.Adobe.com/2006/MXML " " width ="100%" height = "60" > "

  < mx:Script >

            <! [CDATA]

  private function setInUse(): void

                 {

  _data.selected = listInUse.selected;

                 }

  []] >

  < / mx:Script >

  "" " < mx:CheckBox id ="listInUse"width ="18"height ="18"click ="setInUse()"selected =" _data.selected{}"/ > "

  < / mx:Canvas >

  What is listInUse insdie the itemRenderer? I'm not very clear on how you use

  it. However, there are 2 ways to do this. Do not know if data.selected can be used

  to toggle the itemrenderer. I'll so guess not. Have a bindable extra

  "enabled" in your model of dataProvider property. Thus, when you reach the maximum of

  selected items through the collection and defined the set of the activated

  as a result. The enabled property of the renderer is linked to active so model

  It should be updated accordingly. The other way is to bind the license of the

  rendering engine on the selected. But as I said I don't know how your code works...
