    <p>I have a DataGrid in Flex, with one column a checkbox and another a numeric value. When the checkbox is clicked, the numeric value should change, either to 0 if the checkbox is unselected, or to a pre-defined minimum value if the checkbox is selected. Here is the code I have:</p> <pre><code>&lt;mx:DataGrid x="0" y="45" width="272" height="525" dataProvider="{dp}" variableRowHeight="true" editable="true" id="equipmentDG" verticalAlign="middle"&gt; &lt;mx:columns&gt; &lt;mx:DataGridColumn headerText="" headerStyleName="gridheader" width="20" dataField="included" editorDataField="selected" rendererIsEditor="true"&gt; &lt;mx:itemRenderer&gt; &lt;fx:Component&gt; &lt;mx:CheckBox click="handleClicks(event)"&gt; &lt;fx:Script&gt; &lt;![CDATA[ public function handleClicks(event:MouseEvent):void { data.included = !data.included; if(data.included &amp;&amp; data.antal == 0) data.antal = data.minNo; else if(!data.included) data.antal = 0; } ]]&gt; &lt;/fx:Script&gt; &lt;/mx:CheckBox&gt; &lt;/fx:Component&gt; &lt;/mx:itemRenderer&gt; &lt;/mx:DataGridColumn&gt; &lt;mx:DataGridColumn headerText="Antal" headerStyleName="gridheader" width="40" dataField="antal" editorDataField="value" editable="true"&gt; &lt;mx:itemEditor&gt; &lt;fx:Component&gt; &lt;mx:NumericStepper stepSize="1" width="35" height="20" focusOut="numericstepper1_changeHandler(event)"&gt; &lt;fx:Script&gt; &lt;![CDATA[ import mx.events.NumericStepperEvent; override public function set data(value:Object):void { super.data = value; if (value &amp;&amp; value.hasOwnProperty("minNo")) minimum = value.minNo; if (value &amp;&amp; value.hasOwnProperty("maxNo")) maximum = value.maxNo; } protected function numericstepper1_changeHandler(event:Event):void { if(data.antal &gt; 0) data.included = true; else data.included = false; } ]]&gt; &lt;/fx:Script&gt; &lt;/mx:NumericStepper&gt; &lt;/fx:Component&gt; &lt;/mx:itemEditor&gt; &lt;/mx:DataGridColumn&gt; &lt;/mx:columns&gt; &lt;/mx:DataGrid&gt; </code></pre> <p>The value updates in the data (I can see it when I close and open the dialog this is in), but it doesn't update instantly in the data grid. How can I make the value visibly change as soon as the checkbox is clicked?</p>

Guidance
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.
