Visual Basic
C#

'Declaration
 
Public Sub SetDataBinding( _

   ByVal dataSource As Object, _

   ByVal dataMember As String _

)

'Usage
 
Dim instance As WinComboBox

Dim dataSource As Object

Dim dataMember As String

 

instance.SetDataBinding(dataSource, dataMember)

public void SetDataBinding( 

   object dataSource,

   string dataMember

)

Parameters

dataSource: The data source used to populate the WinComboBox, typed as System.Object.
dataMember: A string that specifies the table to bind to within the object returned by the DataSource property.

The following is a list of the supported data sources:

System.Data.DataTable	Represents one table of in-memory data.
System.Data.DataView	Represents a databindable, customized view of a System.Data.DataTable for sorting, filtering, searching, editing, and navigation.
System.Data.DataSet	Represents an in-memory cache of data.
System.Data.DataViewManager	Contains a default System.Data.DataViewSettingCollection for each System.Data.DataTable in a System.Data.DataSet.
Any component that implements the System.ComponentModel.IListSource interface.	Provides functionality to an object to return a list that can be bound to a data source.
Any component that implements the System.Collections.IList interface.	Represents a collection of objects that can be individually accessed by index.
Jagged arrays	A jagged array is an array whose elements are arrays.

If the data source is a jagged array and rows are added or removed from the jagged array from outside of the WinComboBox, then the jagged array must be reassigned to the DataSource property in order for the modifications to be reflected in the WinComboBox.

The following example demonstrates how to bind the WinComboBox to a dataset filled by an ADO data adapter:

Visual Basic

Imports Xceed.Editors

Imports System.Data.OleDb



Dim connectionString As String = "" 'connection query

Dim connection As New OleDbConnection( connectionString )



connection.Open()



Dim selectQuery As String = "SELECT * FROM Clients"

Dim dataAdapter As New OleDbDataAdapter( selectQuery, connection )

Dim dataSet As New DataSet( "Clients" )



dataAdapter.Fill( dataSet )



winComboBox1.SetDataBinding( dataSet, "Clients" )

C#

using Xceed.Editors;

using System.Data.OleDb;



string connectionString = ""; //connection query

OleDbConnection connection = new OleDbConnection( connectionString );



connection.Open();



string selectQuery = "SELECT * FROM Clients";

OleDbDataAdapter dataAdapter = new OleDbDataAdapter( selectQuery, connection );

DataSet dataSet = new DataSet( "Clients" );



dataAdapter.Fill( dataSet );



winComboBox1.SetDataBinding( dataSet, "Clients" );

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
