GridControl with ColorEdit cell

You can obtain the selected color from Renderer.ControlValue of the current cell in CurrentCellCloseDropDown event handler.

C#

private void Form1_Load(object sender, EventArgs e)
{
    this.gridControl1.ColWidths[3] = 100;
    //Set cell type as ColorEdit cell
    this.gridControl1[3, 3].CellType = "ColorEdit";
    this.gridControl1[3, 3].CellValueType = typeof(Color);
    this.gridControl1[3, 3].CellValue = "Blue";
    this.gridControl1.CurrentCellCloseDropDown += gridControl1_CurrentCellCloseDropDown;
}
void gridControl1_CurrentCellCloseDropDown(object sender, PopupClosedEventArgs e)
{
      //Get Grid's CurrentCell
     GridCurrentCell cc = this.gridControl1.CurrentCell;
     if (cc.Renderer is GridDropDownColorUICellRenderer)
     {
         //Convert CurrentCell control value to Color
        Color c = (Color)cc.Renderer.ControlValue;
        Console.WriteLine(c);
        Console.WriteLine("R-Val:"+c.R);
        Console.WriteLine("G-Val:"+c.G);
        Console.WriteLine("B-Val:"+c.B);
     }
}

VB

Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
    Me.gridControl1.ColWidths(3) = 100
    'Set cell type as ColorEdit cell
    Me.gridControl1(3, 3).CellType = "ColorEdit"
    Me.gridControl1(3, 3).CellValueType = GetType(Color)
    Me.gridControl1(3, 3).CellValue = "Blue"
    AddHandler Me.gridControl1.CurrentCellCloseDropDown, AddressOf      gridControl1_CurrentCellCloseDropDown
End Sub
Private Sub gridControl1_CurrentCellCloseDropDown(ByVal sender As Object, ByVal e As PopupClosedEventArgs)
     'Get Grid's CurrentCell
    Dim cc As GridCurrentCell = Me.gridControl1.CurrentCell
    If TypeOf cc.Renderer Is GridDropDownColorUICellRenderer Then
          'Convert CurrentCell control value to Color
         Dim c As Color = CType(cc.Renderer.ControlValue, Color)
         Console.WriteLine(c)
         Console.WriteLine("R-Val:" & c.R)
         Console.WriteLine("G-Val:" & c.G)
         Console.WriteLine("B-Val:" & c.B)
    End If
End Sub
