The commonly used settings of the MultiSelectionComboBox control can be configured either through Designer using the Smart tag or through the Properties window or through code.


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
