Hello,
I have been trying to setup the tree function of that advanced
datagrid but keep running into problems.
I get the error:
TypeError: Error #1034: Type Coercion failed: cannot convert
[EMAIL PROTECTED] to mx.collections.ICollectionView.
I have made some progress, Now instead of getting no data populating
the Advanced Datagrid I get a single Folder that says "Not Available"
public function handleResultRecords(event:ResultEvent):void{
records = new XMLListCollection(event.result.ini.record);
var fields:Array = [];
fields.push(new GroupingField("record"));
gc = new GroupingCollection();
gc.source = records;
gc.grouping = new Grouping();
gc.grouping.fields = fields;
gc.refresh(true);
adg.dataProvider = gc;
}
<mx:AdvancedDataGrid id="adg" designViewDataType="tree" height="100%"
width="100%">
<mx:columns>
<mx:AdvancedDataGridColumn dataField="@id" width="125" />
<mx:AdvancedDataGridColumn dataField="@name" />
<mx:AdvancedDataGridColumn dataField="id" width="125" />
<mx:AdvancedDataGridColumn dataField="name" />
<mx:AdvancedDataGridColumn dataField="value" />
</mx:columns>
