I have created a form with dynamic controls from a table. I need to collect entered by the users values of these controls and send them to another form.
No problem if all controls were text boxes:

foreach (Control ctrl in this.Controls)
{
  MessageBox.Show(ctrl.Text);
}

However I don't know how to get SelectedValue from a combo box or Checked from a check box controls. These properties are not available in the generic ctrl control. I tried to play with GetProperty():

foreach (Control ctrl in this.Controls)
{			
  if (ctrl.GetType().Name == "ComboBox")
   MessageBox.Show(ctrl.GetType().GetProperty("SelectedValue").ToString());
}

I got System.Object SelectedValue. How can I get the value itself?

Thanks in advance
