ASPxComboBox1.TextField = "Name"; //This is the displayMember   
ASPxComboBox1.ValueField = "ID";  //This is the valueMember
ASPxComboBox1.ValueType = typeof(String);
ASPxComboBox1.DataSource = DataTableWithIDandNameColumns;
ASPxComboBox1.DataBind();

String theID = Convert.ToString(ASPxComboBox1.Value);//The column in the datasource that is specified by the ValueField property.
   OR:
String theID = Convert.ToString(ASPxComboBox1.SelectedItem.GetValue("ID"));//Any column name in the datasource.
   Also:
String theName = Convert.ToString(ASPxComboBox1.SelectedItem.GetValue("Name"));

Usually the problem, when the ASPxComboBox's SelectedItem / SelectedIndex is incorrect, occurs when the ASPxComboBox's ValueType http://documentation.devexpress.com/#AspNet/DevExpressWebASPxEditorsASPxComboBox_ValueTypetopic property is specified incorrectly.

Ensure that the ValueType is set, corresponding to the "Data Type Mappings (ADO.NET)" http://msdn.microsoft.com/en-us/library/cc716729.aspx table.

A combobox can only have one value per item and this is retrieved in your case by:

ASPxComboBox1.Value

See here in the documentation.

Since the value returned will be of type object, you will need to cast this to the type originally set, e.g. String. Then you will be able to work with it.

Use ASPxComboBox.Value property.
