Something like this??

C#

itemsComboBox.Items.Add("Dog");
itemsComboBox.Items.Add("Cat");
itemsComboBox.Items.Add("Pig");

private void itemsComboBox_SelectedIndexChanged(object sender, EventArgs e)
{
    switch ((string)itemsComboBox.SelectedItem)
    {
        case "Dog":
            testTextBox.Visible = true;
            break;

        case "Cat":
            break;

        case "Pig":
            break;
    }
}

Does that help?

Sorry I missed the SQL tag. I really have never messed with databases that much so I do not know how to answer your question.

I am sure someone else will be by shortly to help you out but if I find out the answer I will let you know.

Sorry. :(

//Declare Conn,Cmd,dr 1st
//Retrieve Data from Database to Combo Box
string qr = "select * from TableName";
con = new MySqlConnection(ConStr);
con.Open();
cmd = new MySqlCommand(qr, con);
dr = cmd.ExecuteReader();
while (dr.Read())
{
cmbBox.Items.Add(dr[0].ToString());
}
//On TextChanged Event Of CmbBox
private void cmbBox_TextChanged(object sender, EventArgs e)
{
if(cmbBox.Text=="Whatever_Value")
txtBox1.Visible=True;
So on...
}
