How to get the RGB value when a color is selected in the ColorEdit cell in WinForms GridControl?
GridControl with ColorEdit cell
You can obtain the selected color from the Renderer.ControlValue of the current cell in the CurrentCellCloseDropDown event handler in WinForms GridControl.
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);
}
}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
