    <p>i have a datagrid (6 columns) which displays strings from the database. I am trying to use a labelfunction to escape html special characters in the string (like &amp;apos,&amp;amp etc).</p> <p>I found this on the net :</p> <pre><code>protected function makeSpecialChars(item:Object,dgName:DataGridColumn):String { var s:String = agentName.dataField; var v:String = item.s; return new XMLDocument(v).firstChild.nodeValue; } </code></pre> <p>However when i do this I get the error : Cannot access a property or method of a null object reference.</p> <p>This works fine when i change the above code like this :</p> <pre><code>protected function makeSpecialChars(item:Object,agentName:DataGridColumn):String { return new XMLDocument(item.computer_name).firstChild.nodeValue; } </code></pre> <p>where computer_name is the datafield of this datagrid column. </p> <p>Posting Datagrid code :</p> <pre><code>&lt;components:DoubleClickDataGrid xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" xmlns:components="components.*" width="100%" height="100%" editable="true" focusColor="#CEDA9B" rollOverColor="#CEDA9B" selectionColor="#84A207" dataProvider="{invList}" creationComplete="doubleclickdatagrid1_creationCompleteHandler(event)" itemEditEnd="handleInventoryEdit(event)"&gt; &lt;components:columns&gt; &lt;mx:DataGridColumn width="120" dataField="computer_name" headerText="Computer Name" textAlign="center" labelFunction="makeSpecialChars"/&gt; &lt;mx:DataGridColumn dataField="path" headerText="Path" textAlign="center" labelFunction="makeSpecialChars"/&gt; &lt;mx:DataGridColumn width="110" dataField="computer_type" textAlign="center" headerText="Computer Type" /&gt; &lt;mx:DataGridColumn width="180" dataField="username" headerText="Username" textAlign="center" /&gt; &lt;mx:DataGridColumn width="90" dataField="ip_address" headerText="IP Address" textAlign="center" /&gt; &lt;mx:DataGridColumn width="130" dataField="mac_address" headerText="MAC Address" textAlign="center" /&gt; &lt;mx:DataGridColumn width="180" dataField="computer_model" headerText="Computer Model" textAlign="center" /&gt; &lt;mx:DataGridColumn width="70" editable="false" headerText="Actions" textAlign="center" itemRenderer="renderers.ActionRenderer" /&gt; &lt;/components:columns&gt; </code></pre> <p></p> <p>This much is working fine as of now (applied labelfunction to only 2 columns).. But I want to apply the label function to all the columns ...</p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
