I have this form, in which i need to populate a combo box with a text-value pair from the database, so that i can use the value in an update query to the database

i found some method that uses a class to make objects which have both text and a value as:

```
class RequestType
    {
        public string Text { get; set; }
        public string Value { get; set; }

        public RequestType(string text, string val)
        {
            Text = text;
            Value = val;
        }

        public override string ToString()
        {
            return Text;
        }

```

and i added them to the combo box like this

```
RequestType type1 = new RequestType("Label 1", "Value 1");
            RequestType type2 = new RequestType("Label 2", "Value 2");

            comboBox1.Items.Add(type1);
            comboBox1.Items.Add(type2);

            comboBox1.SelectedItem = type2;

```

now i don't know how to retrieve the value of the selected item, i.e. id label 1 is selected, it must return value1 and if label 2 is selected, it returns value2,

any help please??? thanxx in advance
