# 4813 Setting the RowCount Property for Un-bound TGrid Instances Does Not Create the Underlying Rows

I have a TGrid that is populated with data. I try to read the values

Showmessage(Grid1.Rows.Row[0].Value[0]);

But I keep getting the message:

Error. List index 0 out of bounds

Line 1

Comments

Thanks to Raul for gleaning that the developer was setting the unbound RowCount directly, which was the cause of the bug:

I can duplicate the error with unbound if I set RowCount manually and then go and edit the cells (they are set as edits).

Adding rows properly with "grid.InsertRow" works OK.

Either it's a bug (if one can use RowCount to increase number of rows) or RowCount should be read-only property.
