You must override the measure() method in your renderer and use the explicitWidth at the time of measurement to determine the width of the Text controls and then get their measuredHeights and calculate the measuredHeight for the renderer.
Wordwrapped text can be any size. You have to fix one dimension in order to get the other. ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of bigbb_kimo Sent: Friday, March 28, 2008 11:24 PM To: [email protected] Subject: [flexcoders] Change the row height of DataGrid, which contain more than one text compoent? Dear all, I had a datagrid with an item render which contain two Text component and one TextArea. The contents of all the three components are set by htmlText attribute. However, I found that the height of the row can not measure correctly. I have tried to set the wordWrap=true and variableRowHeight="true" of the DataGrid. Please refer to the following code snippet. // start <mx:DataGrid height="100%" variableRowHeight="true" width="100%" dataProvider="{Search.lastResult}" > <mx:columns> <mx:DataGridColumn headerText="Test" width="8" sortable="false"> <mx:itemRenderer> <mx:Component> <mx:Box height="0" width="100%" backgroundAlpha="0"> <mx:Label text="{data.Date}" fontSize="10"/> <mx:Text fontSize="14" width="100%" textAlign="center" htmlText="{data.Title}" fontWeight="bold"/> <controls:AbstractTextArea fontSize="14" condenseWhite="true" wordWrap="true" backgroundAlpha="0" width="100%" height="100%" textAlign="left" htmlText="{data.Abstract}" editable="false"/> </mx:Box> </mx:Component> </mx:itemRenderer> </mx:DataGridColumn> // end I also try to subclass the TextArea to try to dynamic change the height of the surronding Box. However, that is too heuristic to practice. Do you have any good ideas? Thanks a lot.
