I am developing an App that utilizes the UWP DataGrid control from the Windows Community Toolkit.
The control handles validation by turning the background red for scenarios where I have implemented INotifyDataErrorInfo, GetErrors(), HasErrors() and the ErrorsChanged event handler. This level of Validation is built into the control.
The problem with this is that the control does not display the error message returned by GetErrors().
I would like to display the error message below the Cell that has the error similar to what I can do in WPF.
I cannot find a solution anywhere for doing this.
Link to GitHub demo app:

What I have tried:

Written a small demo app to display the default error handing in DataGrid.

Flyouts can be shown positioned relative to a given control (UIElement); which would be whatever is in the cell.

Hy Gerry< thanks for the response, do you know where I could find an example of how to do this?
