[flexcoders] Flex TFTS lesson 8
Hello, Compiled mxml files clean up to the point where you display the horizontal list bar with categories and images. Problem is, NO images no text display just a white area where images and text should display Checked the code over and over, matches lesson code. Anyone have this problem when they did this lesson??? Thanks, Roger

Worked for me. HTH, Chris
[flexcoders] form item and text input control alignment
Hello, When you use a text input control it adds the form item as well for the field label, this is good. When you place the form item and text input control in a VBox how come the text input controls do not line up to the left and the form items line up to the right. They seem to set their alignment on the length of text in the label of the form item. Any Idea's??? Thanks, Roger
[flexcoders] text input controls
Hello, New to Flex and still getting use to everything. When using a text input control why does the width of the text input field change as you scroll through records displayed in a grid control? Also can you right justify the label on the form item that is created when you add a text input control to the form? Thank You, Roger
[flexcoders] date formating
Hello,
I have a date field in a grid.
what is the correct syntax to get it to display MM/DD/
right now it displays as Wed Jan 30 00:00:00 GMT
I have mx:DateFormatter id=df formatString=MM/DD//
as my date format and I added the syntax to the datafield
dataField={df.format(entrydate)}
But this just gives me an error.
I found how to do it on a label but I need it formated in a grid column..
Thank you
Roger
[flexcoders] Re: date formating
Thank you Brian, that worked.
starting to understand this stuff a litte more each day...

Roger,
Use the following function.
public function
gridDateFormatter(item:Object,column:DataGridColumn):String
{
var f:DateFormatter = new DateFormatter();
f.formatString = DD-MMM-;
return f.format(item[column.dataField]);
}
Then on your grid column set the labelfucntion like:
mx:DataGridColumn dataField=date headerText=Dated
labelFunction=gridDateFormatter /
Change the format string to match the format you need.

THANK YOU..
its always nice to have another pair of eyes when dealing with this
syntax!!!
My current dev. tool is nothing like this...

Is catalog misspelled?
categories = event.result.catelog.category;
If there's no catelog child of the XML root, then trying to access a
child of that node will probably throw the error.

[flexcoders] Setting up new project that will us CF to access data
Hello, Newbie to Flex... I want to create a test application in Flex that will get its data using CF via an ODBC connection to the data source. I have already set this up in CF and the connection has been verified by CF. My question is, in Flex when creating the new project should I select Basic or Cold Fusion Flash remoting service? I think I should select Cold Fusion, but When I do that and try to open the newly created main.mxml page(project name is LeadTrack)I get a JRun Servlet Error in the browser and the page just displays the path of my project. 404 /LeadTrack/bin/LeadTrack.html /LeadTrack/bin/LeadTrack.html Any idea's Thank You, Roger
[flexcoders] Re: Setting up new project that will us CF to access data
Yes,I am using the built in CF server. I think leaving the url blank when setting up my the project might be causing the problem! Yes I have complied my project. Let me add the path to the url and see what happens. I notices that they did this in the dvd Beyond the basics, but I was following an other example of an app that currently up and running and I did not see a path in the url??? Still new to all of this, but understanding it once I get a good explanation.

If you are using the built in server, make sure you are putting the port number in the URL.. is the html file in the bin directory? Have you compiled the flex project yet? If you are going to use remoting, then select the remoting project, otherwise select the Basic project.

[flexcoders] binding a data grid column to a text input control
Hello, Flex Newbie! I found an example of data binding from text input to a label, but I need to bind the data from a column in a data grid to a text input control! Any examples? Thank you, Roger
[flexcoders] Re: binding a data grid column to a text input control
I remember the dg.selectedItem.comlumnname now, but I can't remember
wher it needs to go.
When I put it on the line with the text input field as
text={dg.selectedItem.company} I get an error, so I don't think that
is right. I think it goes in a mx:Script block but I am not sure of
the syntax for it.
The column name in the data grid is Company and I want to display that
value in a text input field that is also on the same form...
Still very new to Flex and trying to understand all of the syntax that
goes with it!!!
Thanks,
Roger

{MyLtGrid.selectedItem.Company}
then it worked...
