How do I fill in the 16 custom colors?System.Windows.Forms.ColorDialog

I want to fill in the 16 custom colors with the System.Windows.Forms.ColorDialog.CustomColors, how would I go about doing that?

I also want to save them back to the System.Windows.Forms.ColorDialog.CustomColors is the use changed the custom colors on on ColorUIControl.  Do you have a sample for doing this?

I want to set those programmatically, not selecting from the popup dialog.  I'm using the MFC's color dialog in other apps and I want to transfer those custom color to Syncfusion's ColorUIControl.

Hi Tuan,


Thank you for your update,


We would like to let you know that we have modified the sample for your requirement and it can be downloaded from the below attachment.


Code Snippet [C#]:


this.colorUIControl1.SelectedColorGroup = Syncfusion.Windows.Forms.ColorUISelectedGroup.UserColors;


// To set the color

this.colorUIControl1.UserCustomColors[0] = Color.DeepPink;

this.colorUIControl1.UserCustomColors[1] = Color.Blue;



Please let us know if you need any further assistance,
