{{Attention|Note that Unloaded attribute improves performance by preventing refiltering while navigating away from the page. This attribute should be added to all instances of controls:SfDataSourceExt in your customizing.}}{{Hint|Note that the EvalExpression in Xamarin requires an x:Key, which in turn requires the 'StaticResource ' syntax seen in the <controls:SfDataSourceExt>.}}{{AttentionHint|Note that the Converter seen in the 'EXP' EvalExpressionParameter in Xamarin is 'StringFormat', which is different than in UWP.}}
