I want to be able to get and set the selected row in a TDBGrid. I have dgMultiSelect set to False. I thought about using SelecteRows, but the help files say that SelectedRows is only meaningful when dgMultiSelect is set to True.
Any help would be greatly appreciated.

ahh yes... you're a beginner.
MyTable.first;
MyTable.next;
MyTable.last;
MyTable.previous;
MyTable.first;
While MyTable.eof = false do //eof = end of file or end of table
begin
//do something
MyTable.next;
end;
(here's the opposite)
MyTable.last;
While MyTable.bof = false do //bof = beginning of file (or beginning of table)
begin
//do something
MyTable.previous;
end;
Use the TDBNavigator found on the DataControl's pallete, set its datasource, and your users can use that to navigate through a dataset and this is displayed in the DBGrid.
Good luck

I'm sure the solution is to move the DBGrid's dataset's cursor to the desired record.
One way of doing this is the locate method (depending on the dataset).
This is a basic example
MyTable.Locate('TheNameOfT
...will set the cursor to the record whose field 'TheNameOfTheField' has the value 'TheValue'.
Look up the locate method in the help for more info - you can locate based on more than one field and there are UPPERCASE and LOWERCASE options, too.
There are other creative ways... such as
var
i : integer;
begin
MyTable.First;
//navigate to 100th record
for i := 0 to 100 do
begin
MyTable.next;
end;
