Flex MX datagrid merge columns with a separator

Question

I have a data grid that has regular columns and merged columns. The columns which are merged, displays data multi-line with a line Separator.

I want it to be displayed like this Name/DOB( Name and below it DOB with a separator) in one cell as header. A line separator between Name and DOB.

The data will be placed under the header the same way(Name and DOB below with a line separator).

Name

DOB

Answer 1

You have to use item renderers for acheiving this, The column in which you have two rows will have to have item renderer.

simple exxample try to creasste something like that, but, your renderer will be like below. If this does not work, search for custom item renderer there are a lot of tutorials on that.

<mx:DataGridColumn headerText="Col 2" dataField="col2">
    <mx:itemRenderer>
        <fx:Component>
            <mx:VBox horizontalAlign="right">
                <mx:Label text = "{data.text}"/>
                <mx:Label text = "{data.dob}"/>
            </mx:Box>
        </fx:Component>
    </mx:itemRenderer>
</mx:DataGridColumn>
