Declaration

This article demonstrates how you can declare a RadColorSelector and populate it with colors.

Selection

  • RadColorSelector has a SelectedColor property, which is of type Color and it is used to store selected color value.

        <telerik:RadColorSelector SelectedColor="Red" /> 
    

        RadColorSelector colorSelector = new RadColorSelector(); 
        colorSelector.SelectedColor = Colors.Red; 
    
        Dim colorSelector As New RadColorSelector() 
        colorSelector.SelectedColor = Colors.Red 
    
  • Whenever a color is selected the SelectedColorChanged event is raised:

        colorSelector.SelectedColorChanged += new EventHandler(colorSelector_SelectedColorChanged); 
     
         void colorSelector_SelectedColorChanged(object sender, EventArgs e) 
        { 
           RadColorSelector selector = sender as RadColorSelector; 
           Color selectedColor = selector.SelectedColor; 
        } 
    
            colorSelector.SelectedColorChanged += New EventHandler(colorSelector_SelectedColorChanged) 
     
            Private Sub colorSelector_SelectedColorChanged(ByVal sender As Object, ByVal e As EventArgs) 
                Dim selector As RadColorSelector = TryCast(sender, RadColorSelector) 
                Dim selectedColor As Color = selector.SelectedColor 
            End Sub 
    

Populating

You can populate the RadColorSelector with any of the built-in palettes using the ColorPreset enumeration. It has HeaderPalette, MainPalette and StandardPalette properties, which represent the corresponding parts of the selector.

  • MainPalette property:

        <telerik:RadColorSelector MainPalette="Grayscale" /> 
    

        RadColorSelector colorSelector = new RadColorSelector(); 
        colorSelector.MainPalette = ColorPreset.Grayscale; 
    
            Dim colorSelector As New RadColorSelector() 
            colorSelector.MainPalette = ColorPreset.Grayscale 
    
  • HeaderPalette property:

        <telerik:RadColorSelector HeaderPalette="Office" /> 
    

        RadColorSelector colorSelector = new RadColorSelector(); 
        colorSelector.HeaderPalette = ColorPreset.Office; 
    
        Dim colorSelector As New RadColorSelector() 
        colorSelector.HeaderPalette = ColorPreset.Office 
    
  • StandardPalette property:

        <telerik:RadColorSelector StandardPalette="Standard" /> 
    

        RadColorSelector colorSelector = new RadColorSelector(); 
        colorSelector.StandardPalette = ColorPreset.Standard; 
    
        Dim colorSelector As New RadColorSelector() 
        colorSelector.StandardPalette = ColorPreset.Standard 
    
  • If you prefer to use your own collection of Colors you can always use HeaderPaletteItemsSource, MainPaletteItemsSource and StandardPaletteItemsSource.

    • StandardPaletteItemSource property

              <telerik:RadColorSelector StandardPaletteItemsSource="{Binding Source={StaticResource ColorList}}" /> 
      

              RadColorSelector colorSelector = new RadColorSelector(); 
              colorSelector.StandardPaletteVisibility = Visibility.Visible; 
              Collection<Color> colors = new Collection<Color>(); 
              colors.Add(Colors.Red); 
              colors.Add(Colors.Green); 
              colors.Add(Colors.Blue); 
              colorSelector.StandardPaletteItemsSource = colors; 
      
              Dim colorSelector As New RadColorSelector() 
              colorSelector.StandardPaletteVisibility = Visibility.Visible 
              Dim colors As New Collection(Of Color)() 
              _colors.Add(Colors.Red) 
              _colors.Add(Colors.Green) 
              _colors.Add(Colors.Blue) 
              _colorSelector.StandardPaletteItemsSource = _colors 
      
    • HeaderPaletteItemSource property

              <telerik:RadColorSelector HeaderPaletteItemsSource="{Binding Source={StaticResource ColorList}}" /> 
      

              RadColorSelector colorSelector = new RadColorSelector(); 
              colorSelector.HeaderPaletteVisibility = Visibility.Visible; 
              Collection<Color> colors = new Collection<Color>(); 
              colors.Add(Colors.Red); 
              colors.Add(Colors.Green); 
              colors.Add(Colors.Blue); 
              colorSelector.HeaderPaletteItemsSource = colors; 
      
              Dim colorSelector As New RadColorSelector() 
              colorSelector.HeaderPaletteVisibility = Visibility.Visible 
              Dim _colors As New Collection(Of Color)() 
              _colors.Add(Colors.Red) 
              _colors.Add(Colors.Green) 
              _colors.Add(Colors.Blue) 
              colorSelector.HeaderPaletteItemsSource = _colors 
      
    • MainPaletteItemSource property

              <telerik:RadColorSelector MainPaletteItemsSource="{Binding Source={StaticResource ColorList}}" /> 
      

              RadColorSelector colorSelector = new RadColorSelector(); 
              Collection<Color> colors = new Collection<Color>(); 
              colors.Add(Colors.Red); 
              colors.Add(Colors.Green); 
              colors.Add(Colors.Blue); 
              colorSelector.MainPaletteItemsSource = colors; 
      
              Dim colorSelector As New RadColorSelector() 
              Dim _colors As New Collection(Of Color)() 
              _colors.Add(Colors.Red) 
              _colors.Add(Colors.Green) 
              _colors.Add(Colors.Blue) 
              colorSelector.MainPaletteItemsSource = _colors
