Why isn't the arrow key navigation feature of XamDataGrid working?

edit

There could be several reasons why the arrow key navigation feature of XamDataGrid is not working, including:

1. The XamDataGrid control may not be focused: Ensure that the XamDataGrid control is focused.

2. The AllowKeyboardNavigation property may be set to false: Check if the AllowKeyboardNavigation property of the XamDataGrid control is set to false. If so, set it to true.

3. The Arrow keys may be disabled in the grid settings: Check the XamDataGrid properties for any settings that could disable Arrow key navigation.

4. Custom key events may be overriding the default arrow key events: Check if any custom events or commands are overriding the default arrow key navigation events.

5. Data binding issues: There may be data binding issues with the XamDataGrid control that prevent arrow key navigation. Ensure that the data source is properly bound to the XamDataGrid control.

6. Control not properly initialized: Ensure that the XamDataGrid control is fully initialized before the arrow key navigation is used.
