Overlay text on AdvancedDataGrid in Flex 3

I am trying to overlay a label onto an AdvancedDataGrid when there are no results returned from a call for the data.

Here is a mockup of what I am trying to accomplish https://i.sstatic.net/6Djga.png

I tried following this previous answer: Drawing an overlay in custom flex component, but this would not work for me because an AdvancedDataGrid is not a Container (and as such does not have a rawChildren property).

I would prefer not to need to mess with the data provider, because this table will be used in many location which will have different columns and labelFields.

Any suggestions welcome.

Solution

  • Put the AdvancedDataGrid in a container along with the label overlay. Position the label on top of the DataGrid; and change it's visibility based on the dataProvider's length.
