neutral culture

[Administrator]

i am fairly new at windows forms and i am getting this error when resetting my data datagrid. does anyone have any experience with this error message?

System.NotSupportedException: Culture "en" is a neutral culture. It can not be used in formatting and parsing and therefore cannot be set as the thread's current culture.

thank you,

Is this with an Essential Grid you are getting this message?

Can you post a little sample project showing what you are doing?

yes, this is essential grid. i don't get the error when using the basic datagrid.

if i remove this line from my login screen
Thread.CurrentThread.CurrentUICulture = new CultureInfo("en");

everything seems to work fine. but once i add that line back in, i get the following stack trace

The grid uses the CultureInfo to do formatting for cell values like integers or doubles or ...

And specifying "en" without a Country\Region does not support formatting.

So, if you specify the Country as well, "en-US", then the formatting is permitted, and you will not get the exceptions.

Another option is to use System.Globalization.CultureInfo.InvariantCulture. It is a type of culture that is culture-insensitive. It is associated with the English language but not with a country or region.

thank you, clay, it worked just like you said.
