How to Bind a MultiSelectionComboBox with External Data Source

You can achieve this by using DataSource and DisplayMember properties in MultiSelectionComboBox.

The following code sample defines how to bind MultiSelectionComboBox with datasource.

// Create a DataTable.             
DataTable dt = new DataTable("Table1");

// Adding Columns.
dt.Columns.Add("FirstName");
dt.Columns.Add("LastName");
dt.Columns.Add("occupation");
dt.Columns.Add("place");

// Create a Data Set.
DataSet ds = new DataSet();
ds.Tables.Add(dt);
dt.Rows.Add(new string[] { "John", "Tina", "Doctor", "Italy" });
dt.Rows.Add(new string[] { "Mary", "anu", "Teacher", "America" });
dt.Rows.Add(new string[] { "asha", "roy", "Staff", "London" });
dt.Rows.Add(new string[] { "George", "Gaskin", "Nurse", "germany" });
dt.Rows.Add(new string[] { "sam", "jens", "Engineer", "Russia" });
dt.Rows.Add(new string[] { "Ben", "Geo", "Developer", "India" });

// Create a DataView.
DataView view = new DataView(dt);

// Set DataSource.
this.comboBoxAdv1.DataSource = view;

// Set DisplayMember.
this.comboBoxAdv1.DisplayMember = "place";
' Create a DataTable.    
Dim dt As DataTable = New DataTable("Table1")

' Adding Columns.
dt.Columns.Add("FirstName") 
dt.Columns.Add("LastName") 
dt.Columns.Add("occupation") 
dt.Columns.Add("place")

' Create a Data Set.
Dim ds As DataSet = New DataSet 
ds.Tables.Add(dt) 
dt.Rows.Add(New String() {"John", "Tina", "Doctor", "Italy"}) 
dt.Rows.Add(New String() {"Mary", "anu", "Teacher", "America"}) 
dt.Rows.Add(New String() {"asha", "roy", "Staff", "London"}) 
dt.Rows.Add(New String() {"George", "Gaskin", "Nurse", "germany"}) 
dt.Rows.Add(New String() {"sam", "jens", "Engineer", "Russia"}) 
dt.Rows.Add(New String() {"Ben", "Geo", "Developer", "India"})

' Create a DataView.
Dim view As DataView = New DataView(dt)

' Set DataSource. 
Me.comboBoxAdv1.DataSource = view

' Set DisplayMember.
Me.comboBoxAdv1.DisplayMember = "place"
