To add MultiSelectionComboBox control to a Windows Forms application through code behind,

     using Syncfusion.Windows.Forms.Tools;
     using Syncfusion.Windows.Forms;
     Imports Syncfusion.Windows.Forms
     Imports Syncfusion.Windows.Forms.Tools
  • Create an instance of the MultiSelectionComboBox control and add it to the Form.

    MultiSelectionComboBox MultiSelectionComboBox1 = new MultiSelectionComboBox();
     this.MultiSelectionComboBox1.ButtonStyle = ButtonAppearance.Metro;
     this.MultiSelectionComboBox1.Size = new System.Drawing.Size(217, 30);
     this.MultiSelectionComboBox1.UseVisualStyle = true;
    Dim MultiSelectionComboBox1 As MultiSelectionComboBox = New MultiSelectionComboBox()
     Me.MultiSelectionComboBox1.ButtonStyle = ButtonAppearance.Metro
     Me.MultiSelectionComboBox1.Size = New System.Drawing.Size(217, 30)        Me.MultiSelectionComboBox1.UseVisualStyle = True
