Getting data from dyamic generated DataGridView in another form

[C# Programming]

Hi

I am trying to get data from several dynamics datagridview. The grids are on a tabbed pages. I have set the form and the tab control to public

frmTeacherApp teachApp;


private void btnSave_Click(object sender, EventArgs e)
{
teachApp = new frmTeacherApp();
foreach (Control ctl in teachApp.Controls)
{
//Finding the datagridgrids from a global ArrayList i put the grid
//names in
}
}

but not work. Also try to put the grid into public System.ComponentModel.Container with same result.

Can someone help me?
