ComboBox Null Issue

[obrienkev]

Hi,

I want to set a variable if a ComboBox has been selected.
I initially set comboBox to...

myNameComboBox.Text = "Select Name";

Then I want to check if the user has chosen from the ComboBox list...

            string myName;
            if (myNameComboBox.SelectedItem != null)
            {
                myName = myNameComboBox.SelectedValue.ToString();
                MessageBox.Show(myName);
            }
            else
            {
                myName = null;
            }

However, myName is not set to null when the user does not select from the ComboBox.

Why is this??

The comboBox is databound and DisplayMember, ValueMember and SelectedValue are all set.

Thanks.

The ComboBox functions are inside this function...

private void searchButton_Click(object sender, EventArgs e)
{
...
}
