Hello
In my project I change the date format:

FormatSettings.DateSeparator := '-';
FormatSettings.ShortDateFormat := 'yyyy-MM-dd';

The calendar works fine, but when I open it from the dialog window there is an error.

I have attached a simple example.

Can someone help me?

I haven't tried your project, but my suggestion is to always put that code into the OnShow or OnCreate handler from the main form of your application and being consistent across the whole application.

So I placed the code in OnSchow and in OnCreate, one did not help.

I managed to solve the problem when I removed the default value of the Text property at the design stage.

...Thank you for your help
