----------------------------------
Resolution: Duplicate
> DataGrid height was not calculated correctly
> --------------------------------------------
>
> Key: FLEX-21090
> URL: https://issues.apache.org/jira/browse/FLEX-21090
> Project: Apache Flex
> Issue Type: Bug
> Components: mx: DataGrid
> Affects Versions: Adobe Flex SDK 3.4 (Release)
> Environment: Affected OS(s): All OS Platforms
> Affected OS(s): All OS Platforms
> Language Found: English
> Reporter: Adobe JIRA
>
> Steps to reproduce:
> 1. Create flex project and paste these code:
> <mx:DataGrid dataProvider="{totalDataGrid}" rowCount="6">
> <mx:columns>
> <mx:DataGridColumn dataField="name" headerText="Name"/>
> <mx:DataGridColumn dataField="split"
> headerText="Split"/>
> <mx:DataGridColumn dataField="paid" headerText="Paid"/>
> <mx:DataGridColumn dataField="total"
> headerText="Total"/>
> </mx:columns>
> </mx:DataGrid>
> 2. Provide datagrid with xml data.
> 3. Run the application
>
> Actual Results: I see scroll bar at the right side, which mean datagrid did
> not calculate correct height.
>
>
> Expected Results: The datagrid is suppose to calculate necessary height,
> which I should not see scroll bar at the right side.
>
>
> Workaround (if any):
> 1. If you did not provide xml data by deleting dataProvider, just leave it as
> a blank datagrid. You will not see the scroll bar. When you change the code
> to provide xml data, the scroll bar will show up. This means datagrid does
> not calculate height for the font correctly. If you I hard code the font size
> to lesser than 9, the scroll bar will not show. If I change font size to
> greater than 9, the scroll bar will show up again.
> 2. If you compare a datagrid with no data, and one with data. Both with font
> size greater than 9, but same size. You can make two screenshots of both
> cases and compare them, you will see the one with datagrid's row height is
> higher than than the one without data. You need to change rowCount to some
> number like 30, so it's more noticeable that one row height is higher than
> the other one. The code I provide only has 6 rowCount, which is not that
> noticeable.
