Adding the ColorUI control via designer

  1. Create a new Windows Forms application in Visual Studio.

  2. The ColorUI control can be added to an application by dragging it from the toolbox to design view. The following dependent assemblies will be added automatically:

    • Syncfusion.Shared.Base

Drag and drop ColorUI from toolbox

Adding the ColorUI control via code

The following steps describe how to create a ColorUI control programmatically:

  1. Create a C# or VB application using Visual Studio.

  2. Add the following assembly reference to the project:

    • Syncfusion.Shared.Base
  3. Include the required namespace.

    using Syncfusion.Windows.Forms;
    Imports Syncfusion.Windows.Forms
  4. Create an instance of the ColorUI control, specify its size, and add it to the form.

    // Declaring and Initializing the control
    private Syncfusion.Windows.Forms.ColorUIControl colorUIControl1;
    this.colorUIControl1=new Syncfusion.Windows.Forms.ColorUIControl();
    //Specify the size for the control
    this.colorUIControl1.Size = new System.Drawing.Size(210, 200);
    Adding ColorUIControl to the form
    ' Declaring and Initializing the control
    Private colorUIControl1 As Syncfusion.Windows.Forms.ColorUIControl
    Me.colorUIControl1 = New Syncfusion.Windows.Forms.ColorUIControl()
    'Specify the size for the control
    Me.colorUIControl1.Size = New System.Drawing.Size(210, 200)
    ' Adding ColorUIControl to the form


Select a color and group

At runtime, a particular color group tab should be focused or selected using the SelectedColorGroup property.

The options are as follows,

  • SystemColors
  • StandardColors
  • CustomColors
  • UserColors
  • None (Default)

Use the SelectedColor property to specify the initially selected color.

this.colorUIControl1.SelectedColor = System.Drawing.Color.OrangeRed;
this.colorUIControl1.SelectedColorGroup = Syncfusion.Windows.Forms.ColorUISelectedGroup.StandardColors;
Me.colorUIControl1.SelectedColor = System.Drawing.Color.OrangeRed
Me.colorUIControl1.SelectedColorGroup = Syncfusion.Windows.Forms.ColorUISelectedGroup.StandardColors

These property settings can be reset using the ResetSelectedColorGroup() and ResetSelectedColor() methods.
