Infragistic Grid problem

Hi All

I am using a XAMDataGrid (version 10.3) from infragistic toolkit in WPF windows application. The requirement is that there is only one field i.e. date is editable in the grid and we want that when the user changes the date in that field and click on any other row using mouse click event or moves the keyboard key up or down, there should be an alert prompting to ask if the user wants to save the date or not. if user clicks on Yes then the date should be updated in the database. I am using MVVM approach for this process.

No, problem is when we click the mouse the changed date retains its original value which was before changing the value.

Please help me so that I can achieve my required functionality.

Thanks in advance
