string format not working for DataGridTextColumn?

Put folloing xaml for Currency formating, but not working. Why?

<sdk:DataGridTextColumn  Header="Amount" Binding="{Bin开发者_JAVA技巧ding Amount, StringFormat={}{0:C}}" />

Make sure that Amount is in numeric type. Strings won't format.

Try...

<sdk:DataGridTextColumn  Header="{Binding Amount, StringFormat=Amount: {0:C}}"/>
