I'm sorry, I don;t see what setting the dgData or dgText or
dgNuberofRecords has to do with my original post - I get an internal
Datagird script error when setting the names of the columns (see
original post)

I was referring to dgNumberOfRecords
• get the dgNumberOfRecords
• set the dgNumberOfRecords of group "DataGrid" to 20
• 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.
After setting this property the data grid will send the GetDataForLine message
to the data grid whenever it needs to display data for a particular line. You
can define this command in the data grid script or elsewhere in the hierarchy.
The definition is as follows:
command GetDataForLine pLine, @pDataA
end GetDataForLine
You should fill pDataA with the appropriate data based on the line of data
being requested. pDataA should not have a numeric index. It is the array that
would be assigned to one of the numeric indexes if you were assigning the
dgData property.

This seems like a fragment of a longer thread, but the “dgText” and the
“dgData” are the two methods I use to extract, process and reload the content
of a data grid.

I believe there is a property you set, after which you programmatically control
the population of the datagrid. I am in a hurry so I can't look it up right
now, but it is in the datagrid API in livecode lessons.

I can only image that the customer entered a name with some characters that
Datagrid has a problem with as a column name OR that the shear number of
columns (as the customer is working with a very large dataset) exceeds some
practical Datagrid limit, but what would that be?
