I have created a user control for an address block. It contains the typcial address info fields on it. It has a List property that can be set to a collection of addresses classes. There is also a combo for selecting the type of address.

I the combo's SelectedIndexChange event has:

private void cboPickList_SelectedIndexChanged(object sender, EventArgs e)
{
    _SelectedAddressKey = cboPickList.SelectedKey;
    _SelectAddress();
}

The _SelectAddress() method has:

private void _SelectAddress()
{
    // PK of the Address Type Key record
    int AddressTypeKey = cboPickList.SelectedKey;

    // Clear out the fields on the control
    txtStreet1.Text = "";
    txtStreet2.Text = "";
    txtCity.Text = "";
    txtState.Text = "";
    txtZipCode.Text = "";

    // Find the Address class in the collection
    foreach (Address address in _Addresses)
    {
        if (address.AddressTypeKey == AddressTypeKey)
        {
            // Clear and rebind the addresss class to the fields on the control
            txtStreet1.DataBindings.Clear();
            txtStreet2.DataBindings.Clear();
            txtCity.DataBindings.Clear();
            txtState.DataBindings.Clear();
            txtZipCode.DataBindings.Clear();

            txtStreet1.DataBindings.Add("Text", address, "Street1");
            txtStreet2.DataBindings.Add("Text", address, "Street2");
            txtCity.DataBindings.Add("Text", address, "City");
            txtState.DataBindings.Add("Text", address, "State");
            txtZipCode.DataBindings.Add("Text", address, "PostalCode");

            break;
        }
    }

    txtStreet1.Focus();
}

This works fine for when the user selects an address type that exists in the collection, but for an address type that does not have an address defined, the fields are blank, but nothing is bound to them, I would now need to write code to create a new address, bind to
it, and store it back to the collection.

Anyone have a better way to do this?

Thanks
