This feature request is to provide an option to configure the displayed format of the editor for the GridColumn. It is essential for the numeric and date editing. An alternative would be to follow the DisplayFormat parameter and reuse it in the DatePickers and NumericTextBox. However, we need to gather feedback for the required functionality from our customers.

Scenario

Rendering the grid column like so:

<GridColumn Visible="true" Field="ScalePercent" Title="Scale Percent" DisplayFormat="{0:P5}" VisibleInColumnChooser="false" />

The data in the grid column will show the 5 decimal precision. However, when we go in edit mode the value in the NumericTextBox is restricted to two decimal places.

Workaround

1. Usage of templates

2. Generic change of globalization setting for the NumericTextBox

`culture.NumberFormat.NumberDecimalDigits`
