Well I got as far as
On mouseup
# get data need for the datagrid then
...
put sMap[portalData][tTarget][rowdata] into tRowdataA
reSizeDataGrid (item 2 of extents(tRowdataA) )
set dgData of grp "navMap" to tRowdataA
....
End mouseups
command reSizeDataGrid pNumOfRows #dgText array is set the datagrid
set the height of group "navMap" of me to ( (67*pNumOfRows) )
set top of group "navMap" of me to 100
end reSizeDataGrid
But I have to hard card it...you methods are better.
1) question a hierarchy? The command that we want to use to customize (dgprops
gives everything!). are they better "externalized" the Datagrid before showing
it...OR in better to encapsulate in the behavior script of the DG itself. Say,
in the "LayoutControl" handler.
Of course you are going to say. "Depends on your context, if you want new one
to have the same customization... better make it external."
But then those of you have done this a while have a preferred "best" practice..
What is it?
2) Now, if I could just do a proper "Refresh"
...nothing I will do in the current RowTemplate affects the datagrid...."argh".
which take all it color from Item Inspector of the datagrid as a whole... it as
if the "mask" that the rowtemplate is not being rendering. Just the "elements"
but not the colors and size

get the dgNumberOfRecords

Getting the dgNumberOfRecords is the same as getting the
dgNumberOfLines. Setting the dgNumberOfRecords has a special significance
however. If you set the dgNumberOfRecords then you are telling the data grid
that you know how many total records there are and you are going to supply the
data for each record on an as-needed basis. This is useful when you have data
in a database cursor that you would like to feed into the data grid.
row height
- For tables and forms whose 'fixed row height' property is true this
represents the height that your rows will be drawn at. If this property is not
set for a form whose 'fixed control height' is true then the record template
group height is used. For forms whose 'fixed control height' is false this
represents the height that alternating rows that contain no data will be drawn
at.
So something like:
put the dgNumberOfRecords of group "DataGrid" into tNumberOfRecords
put the dgProp ["row height"] of group "DataGrid" into tRowHeight
Set the height of group "DataGrid" to min(12, tNumberOfRecords) *
(tRowHeight) + 36 -- account for header and scrollbar
