Hi Experts,

I had a Ribbon like custom control. I created an application using this control. These applications work fine until I change the system number format. They crashes if I change the system number format like below:

• Current Format = English (United State)

• Decimal symbol = ','

• Digit group symbol = '.'

When I run applications, they throw an exception "Input string not in Correct format". .

Some other applications specify the Exception's message = "Input string '0,2,0,2' was not a correct format", so I think in Wpf ES's xaml files, we may declare some properties i.e Padding, Margin like "0,2,0,2" => that will cause errors with the system number format above.

I have note that this error only occurs in Windows Vista, it does not occurs on Windows XP. I do not know why?

I have also look at this link, But it not helps for Vista.
