I am working on winforms C #. I took a MonthPicker control in the form of a window. I want to show the Thai calendar no matter what culture is installed on the user's desktop computer, as shown in the image below.

When the user's machine culture is set to English , it displays the English calendar . when the machine’s user culture is set to Thai , it displays the Thai calendar . I want a Thai calendar in both cases .
InitializeComponent(), .

system.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("th-TH");
System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("th-TH");
