[flexcoders] Re: How do you suppress repeating values in DataGrid columns?

[Michael Levine]

Thank you, everyone! I ended up solving the problem with the following
code:

/*
     XML from HTTPService looks like this:

     <books>
         <book author="" title="" />
         ...
     </books>

     XMLListCollection is set as dataProvider for the DataGrid.

*/

var books:XMLListCollection = new
XMLListCollection(XMLList(event.result..books));

// Suppress repeating Author values
var lastAuthor:String = "";
var i:int = 0;
for each (var book:XML in books) {
     if ([EMAIL PROTECTED] == lastAuthor) {
         [EMAIL PROTECTED] = "";
     }
     lastAuthor = [EMAIL PROTECTED];
     i++;
}
