Cast it back to its original type  which will be a DataRowView if you re binding a table  and you can then get the Id and Text from the appropriate columns   foreach object itemChecked in checkedListBox1 CheckedItems         DataRowView castedItem   itemChecked as DataRowView       string comapnyName   castedItem  CompanyName         int  id   castedItem  ID

I ve already posted GetItemValue extension method in this post   Get the value for a listbox item by   index  This extension   method will work for all ListControl classes including   CheckedListBox  ListBox and ComboBox       None of the existing answers are general enough  but there is a general solution for the problem    In all cases  the underlying Value of an item should be calculated regarding to ValueMember  regardless of the type of data source   The data source of the CheckedListBox may be a DataTable or it may be a list which contains objects  like a List lt T gt   so the items of a CheckedListBox control may be DataRowView  Complex Objects  Anonymous types  primary types and other types    GetItemValue Extension Method  We need a GetItemValue which works similar to GetItemText  but return an object  the underlying value of an item  regardless of the type of object you added as item    We can create GetItemValue extension method to get item value which works like GetItemText   using System  using System Windows Forms  using System ComponentModel  public static class ListControlExtensions       public static object GetItemValue this ListControl list  object item                if  item    null              throw new ArgumentNullException  item             if  string IsNullOrEmpty list ValueMember               return item           var property   TypeDescriptor GetProperties item  list ValueMember           if  property    null              throw new ArgumentException                  string Format  item doesn t contain   0   property or column                    list ValueMember            return property GetValue item             Using above method you don t need to worry about settings of ListBox and it will return expected Value for an item  It works with List lt T gt   Array  ArrayList  DataTable  List of Anonymous Types  list of primary types and all other lists which you can use as data source  Here is an example of usage     Gets underlying value at index 2 based on settings this checkedListBox GetItemValue this checkedListBox Items 2      Since we created the GetItemValue method as an extension method  when you want to use the method  don t forget to include the namespace in which you put the class   This method is applicable on ComboBox and CheckedListBox too

EDIT  I realized a little late that it was bound to a DataTable  In that case the idea is the same  and you can cast to a DataRowView then take its Row property to get a DataRow if you want to work with that class   foreach  var item in checkedListBox1 CheckedItems        var row    item as DataRowView  Row      MessageBox Show row  ID            row  CompanyName         You would need to cast or parse the items to their strongly typed equivalents  or use the System Data DataSetExtensions namespace to use the DataRowExtensions Field method demonstrated below   foreach  var item in checkedListBox1 CheckedItems        var row    item as DataRowView  Row      int id   row Field lt int gt   ID        string name   row Field lt string gt   CompanyName        MessageBox Show id          name         You need to cast the item to access the properties of your class   foreach  var item in checkedListBox1 CheckedItems        var company    Company item      MessageBox Show company Id          company CompanyName       Alternately  you could use the OfType extension method to get strongly typed results back without explicitly casting within the loop   foreach  var item in checkedListBox1 CheckedItems OfType lt Company gt           MessageBox Show item Id          item CompanyName
