Hi Nazim,
Thank you for your interest in Syncfusion products.
We don’t have 'IsEasyMode' property in our ColorPicker control and we have not included this in our latest online documentation. Could you please point out, where did you see this property in online documentation?
Regarding your query about change the language of the color picker, you have to generate the Syncfusion.Tools.Wpf.Resources.dll in French culture. Please refer the following link for changing the language and culture of a particular country or region,
