Apply Theme

You can customize the appearance of the MultiSelect control using built-in themes or by designing your own themes. For example, you can apply ShinyBlue theme to the control using the following code:

Public Partial Class MainWindow
    Inherits Window

    Public Sub New()
        InitializeComponent()
        Dim myTheme As MyThemes = New MyThemes()
        MyThemes.MyTheme.Apply(mselect)
    End Sub
End Class

Public Class MyThemes
    Private Shared _myTheme As C1ThemeShinyBlue = Nothing

    Public Shared ReadOnly Property MyTheme As C1ThemeShinyBlue
        Get
            If _myTheme Is Nothing Then _myTheme = New C1ThemeShinyBlue()
            Return _myTheme
        End Get
    End Property
End Class

public partial class MainWindow : Window
{
public MainWindow()
{
     InitializeComponent();

     MyThemes myTheme = new MyThemes();
     MyThemes.MyTheme.Apply(mselect);
}
}
public class MyThemes
{
     private static C1ThemeShinyBlue _myTheme = null;
     public static C1ThemeShinyBlue MyTheme
     {
         get
         {
             if (_myTheme == null)
                 _myTheme = new C1ThemeShinyBlue();
             return _myTheme;
         }
     }
}

Similarly, you can apply any other built-in or your own custom theme to the MultiSelect control. For more information on themes, see Theming.
