Hi Senthil,

This code seems to retrieve displaymembers rather than value members. How can I retrieve a list/array of all selected values:

Hi Thomas.   
Thank you for your update.   
If you want to retrieve Selected Items collection for Value Member type in MultiSelectionComboBox, then we are sorry to say that at present there is no support for this reported requirement in MultiSelectionComboBox. Hence, we have prepared Custom MultiSelectionComboBox inherited from MultiSelectionComboBox.    
Steps Followed   
1)      Created custom control inherited from MultiSelectionComboBox.   
2)      Implemented property named SelectedValues collection that holds Selected Value collection.    
3)      Updated SelectedValue collection, by handling events named “CheckChanged” and “ControlRemoved”.   
Please make use of the below code snippet for your reference.    
Code Snippet: [C#] 
// Custom control to display ValueMember  
public class MultiSelectionComboBoxExt : MultiSelectionComboBox  
//To remove the selected values if it has been unchecked  
void MultiSelectionComboBoxExt_ControlRemoved(object sender, System.Windows.Forms.ControlEventArgs e)  
     for (int i = 0; i <= this.SelectedValues.Count - 1; i++)  
        if (this.SelectedValues[i].DisplayMember == e.Control.Text)  
// To add value members of the selected values into the collection when it is checked  
void MultiSelectionComboBoxExt_CheckChanged(object sender, CheckedStateEventArgs 
      if (e.Checked)  
       this.SelectedValues.Add(new DataCollection(this.SelectedItems[this.SelectedItems.Count - 1].ToString(), e.Item.ToString()));  
We have prepared sample for your reference which can be downloaded from the below location. 
We have prepared a video, which can be downloaded from the below location.

Another way to get the selected values assuming you use a datatable with two columns pk and value (for example) would be the following:

 Public Function getSelectedKeys() As List(Of String)

      Dim pks As New List(Of String)()

        For i As Integer = 0 To Me.SelectedItems.Count - 1

              Dim dr As DataRow = CType(Me.DataSource, DataTable).Select("value = '" & SelectedItems(i) & "'").SingleOrDefault


         Next i

   Return pks

 End Function

Hi Felix, 
Thank you for defining us another method for getting the selected values list in MultiselectionComboBox using Linq . But in order to support all .Net Framework version, we have given the workaround in MultiSelectionComboBox control. 
Please let us know if you need any assistance on this.
