-First, I would Like to know if it is possible to use a Custom Color Dialog when selecting(changing) color from a ColorColumn?
(I can do it for other stuff in my Application but I don't know how in a GridView)
What I Mean by Custom is to be able to Choose Only From the Web Color like that:
RadColorDialog.ColorDialogForm.ShowBasicColors = FalseRadColorDialog.ColorDialogForm.ShowSystemColors = FalseRadColorDialog.ColorDialogForm.ShowProfessionalColors = FalseRadColorDialog.ColorDialogForm.ShowHEXColorValue = FalseRadColorDialog.ColorDialogForm.AllowColorPickFromScreen = FalseRadColorDialog.ColorDialogForm.ShowCustomColors = False-If it's Possible, can you guide me on which Event of the GridView I should do It !
Thank you!

Thank you for writing.
In order to access the color dialog form, you need to subscribe to the CellEditorInitialized event of RadGridView, from where you can access its GridColorPickerEditor > GridColorPickerEditorElement > ColorDialog:
Private Sub radGridView1_CellEditorInitialized(sender As Object, e As GridViewCellEventArgs) Handles RadGridView1.CellEditorInitialized Dim editor As GridColorPickerEditor = TryCast(e.ActiveEditor, GridColorPickerEditor) If editor IsNot Nothing Then Dim element As GridColorPickerElement = TryCast(editor.EditorElement, GridColorPickerElement) Dim dialog As RadColorDialog = element.ColorDialog dialog.ColorDialogForm.ShowProfessionalColors = False ''and so on End IfEnd SubI hope that you find this information useful. Let us know if you have any other questions.

It's seem that the GridColorPickerElement is not existing anymore.
How can I do that now?
Rank 1
GridColorPickerEditor editor = e.ActiveEditor as GridColorPickerEditor; if (editor != null) { GridColorPickerElement element = editor.EditorElement as GridColorPickerElement; RadColorDialog dialog = element.ColorDialog; dialog.ColorDialogForm.ShowProfessionalColors = false; }
In version 2016.1.112 GridColorPickerElement was marked as obsolete and later it was removed:
In the latest version you should use the RadColorPickerEditorElement:
private void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e){ GridColorPickerEditor editor = e.ActiveEditor as GridColorPickerEditor; if (editor != null) { RadColorPickerEditorElement element = editor.EditorElement as RadColorPickerEditorElement; RadColorDialog dialog = element.ColorDialog; dialog.ColorDialogForm.ShowProfessionalColors = false; }}I hope this information helps.

I have the same question but in this case for the RadColorBox. Is it possible to change the colordialog here as well? I only want to show webcolors :
Hope you can help
RadColorDialog MyDialog = new RadColorDialog();
MyDialog.ColorDialogForm.ShowWebColors = true;
MyDialog.ColorDialogForm.ShowBasicColors = false;
MyDialog.ColorDialogForm.ShowSystemColors = false;
MyDialog.ColorDialogForm.ShowProfessionalColors = false;
MyDialog.ColorDialogForm.ShowHEXColorValue = false;
MyDialog.ColorDialogForm.AllowColorPickFromScreen = false;
MyDialog.ShowDialog();
Hello, Victor,
The provided code snippet seems to be correct and it produces the following result on my end with the latest version R3 2020 SP1:
Here you have direct access to the ColorDialogForm and it is possible to control that only the web colors are displayed. Am I missing something? Is the desired requirement achieved?
If you need any further assistance please specify in details what is the exact goal that you are trying to achieved. Thus, we would be able to investigate the precise case and think about a suitable solution. Thank you in advance for your cooperation.

Hi Dess,
Sorry that I have not been clear. The issue is not when calling the dialogbox directly. That works fine.
But is this also possible when using the RadColorBox. Here you get the full dialog, but I only want the web-colors.

RadColorBox internally uses the RadColorDialog as well. The following code snippet demonstrates how to access the dialog in the RadColorBox and show only the web colors:
RadColorBox colorBox = new RadColorBox();
colorBox.Location = new Point(10, 10);
this.Controls.Add(colorBox);
RadColorDialog MyDialog = colorBox.ColorDialog;
MyDialog.ColorDialogForm.ShowWebColors = true;
MyDialog.ColorDialogForm.ShowBasicColors = false;
MyDialog.ColorDialogForm.ShowSystemColors = false;
MyDialog.ColorDialogForm.ShowProfessionalColors = false;
MyDialog.ColorDialogForm.ShowHEXColorValue = false;
MyDialog.ColorDialogForm.AllowColorPickFromScreen = false;Regards,
