Actionscript 3 :: Limit Flex Spark DataGrid ItemRenderer Data To Column

Feb 27, 2012

I've got a DataGrid in my mobile application (I know, I know but there's currently not other solution for this), that numeric values. Depending on the value of a cell, the text gets colored. My big issue is that this doesn't work very for more than about 5 rows of data. I reckon the issue is that the set text function (in which I format the color) can't keep up with the amount of cell changes and formats the text based on the last updated cell of the row.I thought about a column item renderer so that the renderer only gets the value for that column, and not the whole data of the row.

Just for reference, this is my current item renderer (again, this works fine for few rows, for 5+ of fast changing data, this doesn't work any more, cells get formatted even though their data hasn't changed).[code]I just double-checked and have to revert my previous statement. A single row works fine, the second row already messes up the color formatting though. It seems as if the datagrid somehow throws together the values.
Doing the color formatting in the set data method shows the exact same effect;[code]My assumption about the grid messing up the ItemRenderer's data seems to be correct.A simple trace in the set data method (trace("old: " + _oldVal + "new : " + value[column.dataField]);) revealed that somehow, values of the next grid row (in case there are 2) get used as well as _oldVal gets the old value of the next row.

Flex :: Applying PaddingRight To Grid Column Not To Grid Header?

Mar 31, 2010

Whenever I add paddingRight to a column in the flex grid, it adds the padding to the header as well.Is anyone familiar with how I can add paddingRight just to the column and not to the header? Below is the column code where I was specifying the padding.

<mx:DataGridColumn width="60" headerText="Type" dataField="Grade" headerStyleName="headerLeft" textAlign="left" draggable="false" resizable="false" headerRenderer="GridHeaderRenderer" paddingRight="5"/>

Flex :: Use Custom Background Skin On Datagrid Header For Currently Sorted Column

Apr 26, 2011

I use a flex mx:datagrid. I can set the headerBackgroundSkin to specify a skin or a picture to be displayed in all datagrid column's headers and it works just fine !

The problem is I can't find any way to specify a custom skin for the currently sorted column (doesn't matter if the sort is asc or desc, this is just to show the user which column is currently sorted).

I also tried to create a custom headerRenderer for each column but it is quite complicated and doesn't work very well.

I have been looking for the solution for a while but I can't find a good approach to do it. It sounds like a very basic need for me...incredible it is so complicated to achieve with Flex !!

I noticed someone was looking for the same thing few years ago but without success... [URL]

Actionscript 3 :: Flex 4.5 Spark DataGrid - Detect Column Clicked In SelectionChange Handler

Apr 23, 2011

I 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.

The row selection should happen only when one of the first two columns is clicked. How do I achieve this? 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 :: Setting Spark DataGrid Column's Default Sort On Application's CreationComplete

Sep 8, 2011

I have a spark DataGrid component with several columns and I want to have my application default to descending order on the first column in the DataGrid. I would like to use the built-in default sort that occurs when clicking the top header once. I have no need to sort the ArrayCollection I'm working with or change what the comparators are.I also want any user-generated sorting such as clicking on a different column's header to override the default sorting.

Flex :: Top Horizontal Grid Line On Column Chart Is Not Applying Style

Oct 21, 2010

I have a Flex Column Chart that has a range of 0 - 6 on the y-axis. I have added the following block to change the default colour of the horizontal grid lines to black.



This works fine for all but the horizontal grid line at the top of the chart (at y=6). If I change the maximum value for the y-axis to something different then this new max doesn't have the formatting applied (but all the others do).

how do I get the top line to be black like the rest of the grid lines?

Actionscript :: Flex Charting - Fixing The Background Grid And Multi-line Plotting

Jan 19, 2011

I have two requirements for a flex charting component:

1) The grid lines should always remain fixed to a scaling I define using an array of data. Something like a graph paper sheet.

2) Plot multiple line series data over this grid.

How does one get complete control over the background grid lines? I have tried a combination of annotation elements and setting the linechart background elements. If I get the grid right, I can't plot over it (Probably due to the scale). how would one go about designing a graphpaper like interface for linecharts in flex/actionscript?

Flex :: Flash - DataGrid Column Width: One Column To Rule Them All?

Nov 16, 2010

I have a Flex 4, mx:DataGrid with the following (pertinent) properties set:


I have the minWidth set on all of the DataGridColumns and the width set on one of them. If I simply maximize/minimize the display (in browser or stand-alone flash player) of the application, the columns scale up and down nicely. But if you grab the edge of the application and drag it to make it bigger, only one column grows really big. When you drag the size down again, the one column remains big, but all of the other columns get squished way down.
