Center text in Datagrid columns

Hi all,
I need help vertically centering text in a datagrid column.
Does anyone know of a way to do this without custom item
Renderers?

Would really need to see the code to see the extent of the damage Photoshop html has caused. This is a typical problem when exporting html from Photoshop OR trying to assemble the slices into one gigantic table where the cells have been split and merged numerous times which causes distortion.
The idea, looking at your page, would be to insert a simple 3 column x 1 row table into Dreamweaver then insert the components that make up your page into their realtive columns. Using this simple construction method will ensure that all the page elements remain seperate and cannot interact with other element in different cells, which is what is NOT happening in your construction at the moment.

Center text in table column expanding and distorting side columns

Anyone out there that can help me with this, I would appreciate it. I've created the table for this web page in photoshop and sliced it up. The center column is were the body of the text is displayed as you can see from the screen shot. The body text on some of the pages extends below the design of the page. This is dependent on how much content I have of course. If the text continues below the table parameters, the outer cells stretch out, causing separation of the sliced images in the side columns, as you can see in the other screen shot. This only happens in I.E. of course. In safari the table has no problems.
Is there any way to get this under control in I.E? I have tried everything that I can think of. I have battled with this for far too long now.
Any Help would really be appreciated
Thanks,
Duncan

Datagrid column text styles

I have a datagrid column that contains strings in this
syntax: ##% (##%)
When the percentages are over 0% I'd like the text to be
green; when the percentages are under 0%, I'd like to change the
text to red. Apart from breaking this into two columns, how can I
change the colors of different strings inside the same datagrid
column?
Thanks,
Tom

Tom,
One way to do this would be to make a custom ItemRenderer
based on a Label for your dataGrid column. Then, just test whether
you have positive or negative values for your dataField. If it is
negative, use a setStyle('color', 0xFF0000) for red. Here is a
basic example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Label xmlns:mx="
http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[
override public function set data(value:Object):void {
super.data = value;
if (value != null)
if(value.fieldValue >= 0) //fieldValue will need to match
your dataField value from your dataProvider of your dataGrid. You
might need to convert it to an int to compare.
setStyle("color", 0x00DD00);
} else {
setStyle("color", 0xDD0000);
super.invalidateDisplayList();
]]>
</mx:Script>
</mx:Label>
Then in your main app:
<mx:DataGridColumn headerText="Drill Type"
dataField="fieldVAlue" width="105"
itemRenderer="renderers.RedGreen"/>
This assumes that your mxml component is named
'RedGreen.mxml' and is in the 'renderers' directory. You can adjust
this to fit your project as needed. I hope this helps.

Dynamic text in a dataGrid column?

i have a datagrid. i want to populate the first column with a different label depending on the row number.
A good example of this would be
Column 1 label
Label 1
Label 2
Label 3
Label 4
I have these labels in an array, so i could access them if i had the row number.
Anyone know how to do this?
thanks!

Hi peteandrus,
You can simply use the code snippet below to display the labels row wise....
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
 <mx:Script>
 <![CDATA[
 import mx.controls.Alert;
 [Bindable]private var myAC:Array = [
 {Column1:'Label 1', Column2:"Text 1"},
 {Column1:'Label 2', Column2:"Text 2"},
 {Column1:'Label 3', Column2:"Text 3"},
 {Column1:'Label 4', Column2:"Text 4"}
 ]]>
 </mx:Script>
<mx:DataGrid id="dataGrid" dataProvider="{myAC}" x="10" y="177" visible="true">
<mx:columns>
 <mx:DataGridColumn headerText="Column 1 label" dataField="Column1"/>
 <mx:DataGridColumn dataField="Column2" headerText="Column 2 label" />
</mx:columns>
</mx:DataGrid>
</mx:Application>
If you really want to find the row index based assignment you can try something using labelFunction for the DataGrid column...
Something like below:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
 <mx:Script>
 <![CDATA[
 import mx.controls.dataGridClasses.DataGridColumn;
 import mx.controls.Alert;
 [Bindable]private var myAC:Array = [
{Column1:'Label 1', Column2:"Text 1"},
 {Column1:'Label 2', Column2:"Text 2"},
 {Column1:'Label 3', Column2:"Text 3"},
 {Column1:'Label 4', Column2:"Text 4"}
private var counter:int=-1;
 private function column1LabelFunction(item:Object, coulmn:DataGridColumn):String
 var strLabel:String="";
 counter++;
 if(counter < myAC.length)
 strLabel = myAC[counter].Column1;
return strLabel;
 ]]>
 </mx:Script>
<mx:DataGrid id="dataGrid" dataProvider="{myAC}" x="10" y="177" visible="true">
<mx:columns>
 <mx:DataGridColumn headerText="Column 1 label" labelFunction="column1LabelFunction"/>
 <mx:DataGridColumn dataField="Column2" headerText="Column 2 label" />
</mx:columns>
</mx:DataGrid>
</mx:Application>

If myText.text == any value in a datagrid column

Hey guys, in a simple form, I am trying to achieve what's in my title.
I have a text box in which you type in a value (number).
I have a submit button which inserts the value into my data-grid which is populated by a data provider to display that information (ZendAMF).
For my submit button function I need it to loop through all the values(rows) in a column (my dataprovider) of my data-grid to check if my text box value is equal to any of the data in the rows for that column.
I found a function on another forum that should help me achieve this but I still cannot get it to work as I don't think I'm using the function correctly. Note the function is called "findItem()"
Here is my example code:
//I have a datagrid
<mx:DataGrid id="myDataGrid" dataProvider="amfcall.getData.lastResult}">
 <mx:columns>
 <mx:DataGridColumn headerText="MyHeading" dataField="myDataField"/>
 </mx:columns>
</mx:DataGrid>
//I have a form for adding data into the datagrid
<mx:Form id="addData">
 <mx:FormItem>
 <mx:TextInput id="myText"/>
 </mx:FormItem>
</mx:Form>
//I have a button to submit the form data by calling a function
<mx:Button label="Add" id="addData" click="findItem()"/>
//I have the function to find any item in the datagrid column that is equal to the text input in the form. This is what I can't code correctly.
public function findItem(myDataGrid.dataProvider, myDataField:String, myText.text):Boolean
 for each(var item:Object in myDataGrid.dataProvider)
 if(item[myDataField] == myText.text)
 return true;
 return false;
So I don't think I'm correctly typing the first line of the 'findItem' function as I'm currently receiving [I]1084: Syntax error: expecting rightparen before dot.[/I] for this line [I]public function findItem(myDataGrid.dataProvider, myDataField:String, myText.text):Boolean [/I]
Also, the error does not change if I strict type those things to ':Object' etc.
I may just be using the function totally wrong, can anyone hlpe me out?

Hard to tell what’s going on from the information you are providing; but just looking at the first line of your sample code:
Have you checked in the debugger to see what your dataProvider looks like?
You want a resultHandler to set some kind of list – let’s say a previously declared AC, which then becomes your dataProvider for the DataGrid. Something like:
private function amfCallResultHandler(event:ResultEvent):void{
 Var someVar:ArrayCollection = event.result as ArrayCollection;
 blah blah blah;
 myDataProvider = someVar;

Changing a datagrid column image according to the datagrid column value

Flash Builder 4.5 / SDK 4.5.1.
Fairly new to Flash Builder & Flex
Application targets tablets so it's a "mobile" project.
Been beating my head up against the wall on trying to figure out how to do this. Watched videos on Lynda.com. Read Adobe "docs" till my eyes glaze over. Takes me about 2 lines of code in my corresponding .NET project doing the same thing.....
Tried numerous examples. Inline rendering, external rendering files per the examples.
I have a response field in the database and corresponding column in the s:datagrid. If the "reportInfoResponse" field is null (not answered), show an image with a question mark. If yes show an image with "Yes" on it. Same for a no answer.
I get errors of:
1120:Access of undefined property negativeAnswer.
1120:Access of undefined property affirmativeAnswer
1120:Access of undefined property reportInfoResponse
1120:Access of undefined property showResponseImage
If I put this in an external rendering file I also get an error where it can't access the datafield (reportInfoResponse). I've tried data.reportInfoResponse, {data.reportInfoResponse}, {reportInfoResponse} and just plain reportInfoResponse the external rendering file with no luck. I've tried single and double quotes around Y and N. According to all the examples (not to say there aren't more!), I should be able to reference data.reportInfoResponse in the external file and things should be fine. Of course, the examples are bare bones code and I don't have a clue if any importing of classes or other items need to take place. I never see any references of such. The examples also show the image embedding and changing the image by using imageID.source=... In my code it tells me it can't find it.
I have put (ERROR HERE...) on the lines where I'm getting the error messages. I've eliminated a lot of database scripting and such cause that's all working.
Any and all suggestions would be appreciated as I'm pulling out what little hair I have left.......and that's not much at my age........ And yes, I probably could do it by just show text in the column, but that's not what the customer wants... There are other columns I need to do this for so I figure if I can get 1 done and working, the rest are a snap. I CAN use inline or external rendering to show an image. It's the changing it that is the catch.........
Thanks in advance!

Ioan Thanks for the reply.
Probably my previous explanation of the problem was a little incomplete. Let me give a better description.
The situation is something like this.
I have a requirement in which the customer wants the column header to reflect the 'keep filter value' restriction that he does dynamically in the query report.
i.e:
-- usually the kf column header shows 'sales volume'
-- column header with text variable of the Calender year / month variable -- 'sales volume for 2000 oct'
-- but when the report is run, if the user wants to go and change the filter: calender year / month > rt clk > keep filer value > select Jan 2003.
The kf column header still shows 'Sales Volume 2000 Oct'
How to make the column header change to 'sales volume for Jan 2003' ?
Any suggestions greatly appreciated.
Thanks,

How to center text in Pages to show correctly on iBook Reader

Hi,
First, I have to say that I posted the same question on ''Creating ePubs'' discussioun page but nobody could help.
I am trying something really easy but could not solve it. Hope someone can help.
Ok, I know that if I choose ''Chapte Name'' as a pharagraph style, iBook reader automatically puts it into a new page, so the new page starts with the chapter name on top. I dont have any problems with my chapters.
However, I want my book to start with a page that has a brief info about the author. I want this info in the middle of the page (also centered in the middle). Than I want to go to the second page with a ''dedication'' part where I write my thanks to people. I also want this in the middle and centered. And finally I want to add my book title and author name together on the 3rd page. After that the chapters will start.
So, as I told you, the chapters work just fine. But when I try to center the text in the first 3 pages, (I press return several times on my keybord to do it) the pages interwine with each other. For example, the last part of page 2 goes on top of page 3.
I think this happens because I press the return key to center the texts. So, is there a way to lock texts to the pages where they belong to prevent them to interwine with other pages even if I press return to center the text
OR
Is there another way to center text to prevent them to interwine with other pages...
Thank you

One of the consequences of working all night on this was that there is errata, or improved insight.
As I mentioned previously, each of the four document parts that I tested is in its own section. This means that each of the first three document icons, in thumbnail view, has its own distinct yellow race track around it. The chapter/body text is in a fourth multi-page section.
On the first page, with invisibles and layout mode shown, I have a ¶ (pilcrow) showing on line 1, column 1. If I place the cursor before this mark, the text inspector shows the following:
Style is body
Character spacing is 0%
Line spacing is single (1)
Before paragraph is set to 172 pt.
After paragraph is set to 6 pt.
Now, if I place the cursor before the About the Author string:
Ruler set to 1.6 inches
Style is Heading 1
Character spacing is 0%
Line Spscing is single (1)
Before paragraph is set to 196 pt
After paragraph is set to 6 pt
Place cursor between end of Author and Pilcrow and press return.
With the cursor before the author description:
Style is body
My font choice was Baskerville, Regular 12 pt.
Left ruler set to 1.6 inches. Right ruler to 6.2 inches.
Character spacing is -4%
Line-height is set at multiple (1.2)
Before paragraph is 0
After paragraph is 12 pt.
Position cursor between last character and pilcrow - press return.
Insert section break
This is all there is too my first page:
For the Dedication page:
Line 1, Col 1 has the pilcrow and style is body
Character spacing is 0%
Line height is single (1)
Before and After paragraph are set to 0
With the cursor just before Dedication:
Left ruler set at 2.6 inches
Style is Heading 1
Character spacing is 0
Line height is 1.5
Before paragraph set to 190 pt
After paragraph set to 0 (yeah, raised my eyebrow too)
Place cursor between trailing n and pilcrow, press return.
With cursor on first line of names, just prior to first character:
Style is body text with Baskerville Regular 12 pt override.
Text justification is left.
Left ruler is set to 2.9 inches
Right ruler is set to 6.7 inches
Character spacing is 0
Line-height is 1.2
Before and after paragraph are 0
Insert cursor before last Pilcrow and press return
On the next line, there is a Pilcrow at col 1, place the cursor in front of it.
Style is body style
Character spacing is 0
Line-height is multiple (1.2)
Before paragraph is 0
After paragraph is 216 pt.
Press return to set the jump.
Insert section break
You can likely insert step 14 at step 7 and skip 9 - 13. It was late.
The Dedication page looks like this:
Hopefully, you missed something, or it wasn't sufficiently explained previously. I hope you can duplicate the above and discover unique, centered content in your ePub.

Vertically center text in a textbox

Like Indesign, a way to vertically justify or center a text in a textbox.

I don't know if there is a way to automatically center the text, but you can play with padding, if font size and height are fixed:
.text-box *.viewport {
    -fx-padding: 15 5 3 5;
// Tested with:
TextBox
    text: "Hello World"
    columns: 12
    selectOnFocus: true
    layoutInfo: LayoutInfo { height: 50 }
}

Dynamic DataGrid columns

How can I get this example to wok with <mx:HTTPService>

Dynamic DataGrid columns
Example of how to dynamically create DataGridColumns
A completely dynamic DataGrid example.
This example uses the xml from the Flexstore example. It
examines the first product node and uses that to create the
definitions for the columns. There is some example logic to change
the columns properties.
It then instantiates the GataGrid and its columns array,
assigns the properties, and then the dataProvider, and then adds
the dataGrid to the application container.
The example is fully self-contained, since a portion of the
catalog.xml file is included in the mxml.

How not to sort datagrid column on double click

Hello,
I am currently building an application containing a datagrid for data representation. I've created a custom datagridheader in order to add a input text for filtering the columns (see code below).
My goal is to hide the textinput, and then show it on a double click on the header. So i would like to know how to avoid the sort of this column each time i double click.?

Based on your idea, i've intercepted the click event and I use stopImmediatePropagation.
THen i added an image to sort the column. So if the image is clicked the sort is ok.

ItemRenderer in a datagrid column setStyle() does not do anything to the appearance

I have a custom ItemRenderer in a datagrid column, however
the setStyle() does not do anything to the appearance. when it is
called. Any ideas?

}else{
setStyle("backgroundColor",0xff0000);

Your renderer code looks a little strange. This works, and
may get you started:

Datagrid column header word wrap issue

Hi All,
I'm passing dynamic text to a datagrid column header. The word wrap is true but it's not working.
Any ideas how to fix this issue?
DataGridColumn headerText="{myVar.text} Total" headerWordWrap="true"
Thanks
Johnny

@Johnny,
Try to make use of the headerRenderer property and use <mx:Text /> control as a renderer so that your headerText gets wrapped..
Thanks,

Setting the editable property of a datagrid column dynamically

Hi,
Im trying to set the editable property and renderer is editable property for a datagrid column to false on the creation complete event of the datagrid.But It does not work.While visible property works.why doesnt the editable property work.The particular column has a renderer which is a text box.and the editable property is set to false initially.Any Suggestions or ideas on how to achieve this will be of great help.

Eu tenho vontade de estar devidamente por dentro de tudo isso.

DataGrid column width is not set properly

Hi,
 In the below example I has called the OptimizeDataGrid method on Button Click event to resize the Column according to the data. First time of the button click event it called the function whereas the Datagrid Column width alone is not set properly.whereas on second time it is working properly.
For Eg : In the below statement the text value is coming as 55 and widthPadding is comes as 25. but the sum of these two value is not in the dg.columns[col].width.
dg.columns[col].width = text + widthPadding;
But the same is working on the second time of the Button click event. is any help me out to resovle this issue. Thanks in Advance.

With horizontalScrollPolicy="off" (the default), it is hard to control
column widths because the columns are sometimes overridden to make sure they
fit on the screen.
