DataGrid TextBox does not accept Double values

Question

Hello,
I have a DataGrid with a TextBox wich represents a double value. If this double holds an integer: no problem, i can put there 1, 10, 100 or 100000000 and i get no error.
Instead if i put there a fractionary number, ex: 0,1 or 0,01 it throws an exception that i can catch in "dataGridView1_DataError" with a message something like "Value too big or too small for Int32.", but where did DataGridView got the idea that this value should be an Int?
Thank you,
Joaquim

I can only think that the data source you're binding to is expecting an int rather than a double.
If it were expecting a double but you gave it an int, then that would be no problem as you can always implicitly convert ints to doubles but not the other way around.
