You could set the Format property to something like "d" for when it is not in edit mode but when you are in edit mode you are going to see all of the mask characters.

I have the same problem. I need to allow up to 12 digits, not counting the decimals. According to your statement regarding Double, it should work, but it doesn't.

I am able to type more than 9 characters into the editor if I set the Mask accordingly, but when I press Enter or focus away from the control, the value is lost if it contains more than 9 digits. Anything up to 9 digits, and the value is preserved in the cell. I am trying XamNumericEditor, XamCurrencyEditor, XamMaskEditor, as well as different data types (double, Int64, currency, etc.)... It makes no difference.

Here is my test control, which is part of a XamDataGrid. Any help will be very appreciated:

<ig:Field Name="Dollars" >
<ig:Field.Settings>
<ig:FieldSettings AllowEdit="True" EditAsType="{x:Type sys:Double}">
<ig:FieldSettings.EditorStyle>
<Style TargetType="{x:Type ig:XamCurrencyEditor}" >
<Setter Property="Mask" Value="{}{double:12.0}" />
<Setter Property="Format" Value="C0" />
</Style>
</ig:FieldSettings.EditorStyle>
</ig:FieldSettings>
</ig:Field.Settings>
</ig:Field>

Thanks for the reply and the sample project. I was able to run your project and get it to work, even in a XamDataGrid.

However when I am using the exact same approach in my project, the Mask does not work. I looked at the XamNumericEditor rendered by the datagrid using Snoop and compared it with your sample project and they are the exact same. I am really not sure what I am doing wrong here, I tried with different object model as well and different DataSource, same result... this is really weird. I can't send you the project as it is pretty big and it is our customer's project with copyright material.

I will post the solution if I even find it.

I am also looking for setting the Mask for XamNumericEditor to have more than 9 integer digits. Please let me know if anyone got the solution.

Thanks

I came across this thread and I still can't figure out how to allow the XamNumericEditor in a XamDataGrid to allow a number more than 1,999,999,999.99... Here is what I tried with no success:

<Setter Property="Mask" Value="nnn,nnn,nnn,nnn,nnn.nn" />
OR
<Setter Property="Mask" Value="{}{double:15.2}" />

The 2 solution above creates a mask with the correct number of prompt char but it is still not allowing me to enter more than 10 integer digits.

Anybody has a solution that allow me to enter say 234,567,890,123,456.12 ? Thanks.
