I think something like this can be done.
In
Form
a
DataTable
say
DataTable1
is created and it is populated with the values from the
TextBoxes
.
In
Form2
make the visibility (accessibility) of
DataGridView
as
public
.
Then in the
Click
event of
Button1
of
Form
Form2 form2 = new Form2();
Form2.DataGridView1.DataSource = DataTable1;
Form2.ShowDialog();
Form2.Dispose();
