dgtext isn't an array value, to do what you want you need to get the dgdata
For example, if you have a simple table grid with 2 columns, col1 and col2 with 3 records, to get the array back out do *get the dgdata of group "yourdatagridgroupname" * *put it into tArray* At this point, knowing whats in the grid if you *put the keys of tArray* since there are 3 records, the keys will be 1, 2 and 3 will be displayed in the message box. If you then *put the keys of tArray[1]* you will see the column keys, col1 and col2, so to get a specific cell is as you've been trying to do with the dgtext tarray[1]["col1"] will get the data from row 1 col 1. if you get the dgtext, it should react like a tab delimited flat file. So if you *get the dgtext of group "mydatagridgroup"* *put it* it should display all rows and columns of the datagrid in the message box On Fri, Jun 3, 2011 at 7:09 PM, Van Brollini <analog_t...@runbox.com> wrote: > I have a datagrid of 1250 by 28 that has been successfully uploaded during > the creation of the datagrid. > > I can use this line > put the dgText of group "DGTester" into tArray > to move the datagrid into an array.
