I'm not sure why you're seeing a performance hit since essentially that code would modify the default style. That being said you can change the default mask used for a type using the static RegisterDefaultMaskForType method:

Hi Vlad,

I  figured out by using XamNumericEditor.
But this leads to performance issues,  it is slower than default setting.

Thank!

Vlad,

It does not work. I guess the dataGrid does not know it is a currency field.

How to set it for all numeric  fields?  

Thanks!

Steve

Hi Steve,

In this case you need to create a default style for XamCurrencyEditor
without specify x:key of the Style. This way you will provide a default
style for all the XamCurrency editors in the grid.

This is an example how can you do this in Xaml :

<igDP:XamDataGrid.Resources>
       <Style TargetType="{x:Type igEditors:XamCurrencyEditor}">
            <Setter Property="Mask" Value="{}{currency:10.2:c}" />
       </Style>
</igDP:XamDataGrid.Resources>

Of course you can set the style in Code behind as well.

Regards

Vlad

Hi Vlad,

I  am binding the result set  automatically, so no indiviual field specified in xaml. How can I set the mask for all XmlDataGrid?  

Thabks!
