I have also tried maintaining a dictionary of primary keys that have been edited. My valueconverter then looks for the current record's pk in the list, and returns Brushes.Red if it's there, otherwise Brushes.Black. When I save to the db the dictionary is cleared.

This ALMOST works but not quite. I have to scroll so that the edited record is out of sight, then scroll it back into view, to make it go red!

Help!

Actually I want to set the cell border of the record BELOW the edited cell to change color.

The [0] index record contains a Billing Rate for an employee.  This billing rate can be changed by the user.  I use XamNumericEditor for these updatable fields.

The [1] index record contains a calculated Effective Multiplier based on the billing rate divided by the actual pay rate.  This record cannot be updated by the user.  I use XamNumericEditor for these fields, even though they cannot be updated, for the benefit the XamNumericEditor gives me in formating the presentation of values.

When the [0] index record billing rate is changed the [1] index record caculated field changes.  If this calculated value is below a threshold value I want the field border to change color on the [1] index record, not the [0] index record that was actually updated.

I have not been able get a reference to the [1] index record cell editor from inside the [0] index record EditModeEnding event.

A complicated explanantion for a simple issue to resolve I hope.

Are you saying that you want to set the border for the selected cell and the cell directly below it in the next record?

You solution to highlight the changed cell works great for me.  Of course I need to to do more and also want it to highlight the cell editor border of the cell below.  This specific grid contains static data and changing the value of one cell causes a calculation be performed and displayed in the cell of the DataRecord below the DataRecord being changed. 

Here is my code from EditModeEnded.  After the user updates the cell in DataRecord[3], I am attempting to reference the cell in DataRecord[4] at the corresponding index - multCell. I cannot get a reference to the Editor of multCell, I can get DataPresenter, EditorStyle, Field, Record but have not found a path to the cells Editor to set its Border color.  The properties I can get a hold of change the settings for every cell in the grid or lead me back to the cell. 

if (effMult < (decimal)2.9)

e.Editor.BorderBrush = Brushes.Red;

Hi Robert,

You can either explicitly change the brush in an event handler. Or you can keep a reference to a dynamic brush resource. Changing the brush in your code will cause the brush to update in the UI. The XamDataGrid takes advantage of WPF features such as DynamicResources.

Let me know if you need further clarification.

Thanks!
