What you want to do is set the 'dataTipFunction' property on the DataGridColumn class to point at your custom function.
<DataGridColumn .... showDataTips=true dataTipFunction="createCustomToolTip()" And you'll want to change the declaration of your createCustomTooltip to a single item of class Object. The object that will be passed in is the object that represents the target row of data in the grid. You can recast that back into whatever it really is inside createCustomTooltip --- In [email protected], "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > You want to look at "dataTip" instead of "toolTip". > > Tracy > > > > ________________________________ > > From: [email protected] [mailto:[EMAIL PROTECTED] On > Behalf Of Steve House > Sent: Wednesday, January 24, 2007 3:09 PM > To: FlexCoders > Subject: [flexcoders] DataGrid Tooltips > > > > With Flex 2, when the user mouses over a row in a datagrid, I would > like to show details of that particular row's object in the tooltip. > The datagrid dataProvider is an ArrayCollection of objects with many > properties.
