Spark DataGrid Change Cell Color

Posted: October 31, 2011 in Flex

Believe it or not, the simple task of changing a cell color when the data is changed (another cell is edited) wasn’t as easy as it might sound. Not just setting it when the grid fills up, but changing it during the course of editing the grid.  Took me a couple weeks to solve.  So, I’m passing it on to you.  Hope it saves you some time!

 


<s:DefaultGridItemRenderer>
<fx:Script>
<![CDATA[

override public function prepare(hasBeenRecycled:Boolean):void
{


textColor = 0x000000;

if(data){
text = data.action;

if(data.action == ’Keep’)
opaqueBackground = 0x00ff00;
else if (data.action == ’Update’){
opaqueBackground = 0xFFCC00;
}
else if (data.action == ’New’){
opaqueBackground = 0xffff00;
}
else if (data.action == ’Delete’){
opaqueBackground = 0xff0000;
}
else {
opaqueBackground = 0x000000;
}
}

}
]]>
</fx:Script>

</s:DefaultGridItemRenderer>

    There is a bug with spark datagrid opaqueBackground. If your cell color extends into the next column, set the width of the GridItemRender to 100% or a fixed value. This will keep the color inside the cell width.
