WinForms Comboboxes

[Illegal Operation]

Hi, I have two comboboxes, cbPhysicalCountry and cbPostalCountry. Both Comboboxes are populated via a dataset. How can I set the cbPostalCountry = cbPhysicalCountry when the user checks the checkbox "UsePhysicalCountry"? I populate my comboboxes with the following code

DataSet dsPhysicalCountry = WCFService.GetCountry();

cbPhysicalCountry.DataSource = dsPhysicalCountry.Tables["Country"];
cbPhysicalCountry.DisplayMember = "Country";
cbPhysicalCountry.ValueMember = "Id";

When the checkbox_checkchanged event fires I have the following code,

if(checkbox.checked == true)
{
cbPostalCountry.SelectedItem = cbPhysicalCountry.SelectedItem;
}

Thank you in advance...

try this way, if (checkBox1.Checked == true) cbPostalCountry.SelectedValue= cbPhysicalCountry.SelectedValue;

What happens if the postal and physical countries are different? Try SelectedValue instead of item. Try using a BindingSource instead of a table.
