Winforms-Combobox, Listbox and Enums - URGENT

Question

Hi all...

I need help in Combo Box, List box and Enums in Windows Applications in C#.

My requirement is -

I have an Enum - Colours.
public enum Colours
{
Red=1, Blue, Green, Purple, Brown, Yellow , Black}

I want to bind this enum with combo box in such a way that-
Combo Box items are - Red, Blue, Green, Purple, Brown, Yellow , Black.
Combo Box Value Member - Index of colours i.e. 1,2,3,5,6,7.
Listbox items are - Red, Blue, Green, Purple, Brown, Yellow , Black.
ListBox selectedValue -Index of colours i.e. 1,2,3,5,6,7.
----------
Scenario-When user selects a colour(say Blue), then value (here 2) should be stored in database.

Please help..

Thanks all in advance

You can bind an enum to a combobox or listbox with a line such as this: comboBox1.DataSource = Enum.GetValues (typeof(Colours)); The names of the colours will then be displayed in the box and the SelectedValue (and SelectedItem) properties, both of which return an object, will then contain a boxed version of the index of the selected colour. To retrieve the index as an int you will therefore need to use a cast or apply a conversion function: private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) { MessageBox.Show(Convert.ToInt32(comboBox1.SelectedValue).ToString()); }

This is not possible using Enum. You have to create a class to achieve this, see the below sample: Class : public class Colors { public int Id { get; set; } public string Name { get; set; } } Assign the value: var colors = new List { new Colors(){ Id = 1, Name = "Red"}, new Colors(){ Id = 2, Name = "Blue"}, new Colors(){ Id = 3, Name = "Green"}, }; Bind this object to combobox or listbox.
