Summary0018590: TStringGird: Typo in EGridException "FixedRows can't be >= RowCount"
DescriptionI have a TStringGrid with FixedRows=1 and RowCount=1 (set in the ObjectInspector).

In my application I add and remove rows (either by using DeleteRow(Index) or by reducing RowCount), and on occasion the grid becomes empty (with just the fixrow left), which produces the exception:

"Project XYZ raised exception class 'EGridException' with message: FixedRows can't be >= RowCount"

In my case I did screw up my own code, but the exception message is not correct.

Seems that a TStringgrid works just find with FixedRows=1 and RowCount=1 since I can set it just fine in the ObjectInspector.

I suspect it should be "FixedRows can't be > RowCount".

(if there are no rows besides the FixedRows, then RowCount=FixedRows)
Additional InformationMacOS X v10.6.6, XCode 3.2.5

AFAIR from kylix, if you have fixed rows then minimum rowcount should be 2.
I don't think that this is bug.

You're right :(
Delphi does require Rowcount>FixedRows as well. (I tried it just now in Delphi 2007).

I feel like I'm shooting in my own foot now ...

I really like the fact that I can have FixedRows=RowCount (so that only a header shows). Both in code and in the ObjectInspector I can do this just fine without any error messages.

The point I was trying to make was that the error message doesn't add up with reality :)

The message appeared when I had RowCount < FixedRows. It does NOT appear when RowCount=FixedRows. Though it suggests that the error should appear when RowCount <= FixedRows.

So the message should instead (in my favor) say (wihtou the '=' sign):

"Project XYZ raised exception class 'EGridException' with message: FixedRows can't be > RowCount"

Message now reflects current behaviour.
If you feel that current behaviour (FixedCols can be ColCount) is wrong then please file a separate bugreport.
