datagrid / dataset.haschanges questions

[amberlynn]

Hello,
I'm unsure on how best to do this:

I have a datagrid, bound to a dataset.
I use if dataset1.haschanges - save datagrid data.
But this doesn't work if there is no data in the dataset (which is common).
So if no data exists (the datagrid is blank) and the user type a row of data, dataset1.haschanges still returns false.

How do I get around this?
Thanks,
Amber

you can count the number of records in your dataset and see if it's different than when it was first loaded:

private function getNumberOfRecord(myDataSet as dataset) as integer

dim i as integer = 0

for each table as datatable in mydataset.tables
i += table.rows.count
next

return i

end function

But if the dataset.haschanges doesn't work, because the original dataset never fills - counting the records will return zero before and after I've added a row to the datagrid...won't it?
Otherwise wouldn't .hasChanges return true?

TIA
Amber

What about adding
dataset1.AcceptChanges
when user change any row of the dataset1?
