I'm having the following problem: I've implemented a custom headRenderer for my DataGridColumn. The idea is to have a dropdown menu when clicked on the column header. The problem is I don't know how to add a listener or pass a variable to the renderer since the renderer class is instantiated by the ClassFactory. The renderer class: <pre><code><?xml version="1.0"?>  <mx:HBox xmlns:mx="library://ns.adobe.com/flex/mx" xmlns:fx="http://ns.adobe.com/mxml/2009" width = "100%" > <fx:Script> // ... // Event handler for the Menu control's change event. private function menuHandler(evt:MenuEvent):void { //Alert.show("Label: " + evt.item.@label, "Clicked menu item"); if (evt.item.@eventName == "typeLat"){ typeIcon.load("assets/type_location.jpg"); evt.item.toggled=true; //variable.setColumnType(myLabel.text, "type"); // how can I pass "variable" to this renderer? } else if (evt.item.@eventName == "typeLng"){ typeIcon.load("assets/type_location.jpg"); evt.item.toggled=true; } else if (evt.item.@eventName == "typeTime"){ typeIcon.load("assets/type_time.png"); evt.item.toggled=true; } else if (evt.item.@eventName == "similarity"){ dispatchEvent(new SimilarityEvent("selectSimilarity", null, null)); // how to listen to this event? } } </fx:Script> <fx:Declarations> <fx:XML id="myMenuData"> <root> <menuitem label="Select type..." eventName="copy"> <menuitem label="Other..." eventName="typeOther"/> <menuitem type="separator"/> <menuitem label="Order" type="check" eventName="typeOther"/> <menuitem label="Range" type="check" eventName="typeOther"/> <menuitem label="Date/Time" type="check" eventName="typeTime"/> <menuitem label="Latitude" type="check" eventName="typeLat"/> <menuitem label="Longitude" type="check" eventName="typeLng"/> </menuitem> <menuitem label="Define similarity..." eventName="similarity"/> <menuitem type="separator"/> <menuitem label="Filter objects..." eventName="similarity"/> <menuitem label="Order" eventName="similarity"> <menuitem label="Ascending" eventName="typeOther"/> <menuitem label="Descending" eventName="typeOther"/> </menuitem> <menuitem type="separator"/> <menuitem label="Remove" eventName="paste"/> </root> </fx:XML> </fx:Declarations> <mx:Label id="myLabel" click="showMenu();"/> <mx:Image height="20" id = "typeIcon"/> </mx:HBox> </code></pre> Here is how I instantiate the renderer: <pre><code> var newColumn:DataGridColumn = new DataGridColumn(); newColumn.dataField = attr; newColumn.headerText = attr; newColumn.sortable = false; newColumn.editable = false; newColumn.draggable = false; newColumn.headerRenderer = new ClassFactory(newviews.RendererDataHeader); cols.push(newColumn); </code></pre> any help will be highly appreciated

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
