Calculate number of rows in a DataGrid

[Terence Heaford]

How can I calculate the number of rows in a DataGrid.

I don’t mean the dgNumberOfLines as this is just the number of rows containing data.

I actually need the number of visible rows. The DataGrid can be resized by script.

It is straightforward where the height of the header and the height of a row is fixed but I was hoping the information may be a property of the DataGrid but I can’t seem to fined one.


Thanks
