Hello,
Today I have an issue with manipulating the contents of the Row Indicator column. The functionality we need is to insert an asterisk (*) inside the Row Indicator cell whenever the row is edited, effectively created a marked for unsaved changes.
I can manage to do this by inserting code into the Cell Edit Ended event that. I collect the IndicatorPresentor using ChildrenOfType on the row, and insert a simple textblock into the IndicatorPresentor's Content property.
The problem is that this only works sometimes. If I do not do any actual editing to the cell, the indicator will change as appropriate. If I do change the cell, however, the normal triangle indicator shows up. Stranger, if this occurs, any other asterisks inserted into other Row Indicator cells dissapear as well.
It seems as though all the indicator rows are being reset upon row edit. This happens not just if insert a textbox, but even if I change the background color as well. I was wondering if you had a way to get around this, or if this was indeed an issue with Radcontrols and not my grid itself.
Thank you for your time,
Philip Coffey

This issues has been partially resolved (it was our code, not the controls), but this has presented a further problem to us. Now the problem being presented to us is that inserting a textblock into the indicator cell through the Content property seems to cause an exception that ultimately originates from MS.Internal.XcpImports.VisualStateManager_GoToState(Control reference, String StateName, Boolean useTransitions), and occurs after around the third row edit or so.
So I my question is revised thusly: what is the most effective and safe way to change the contents of the indicator cell such that it doesn't cause instability?
Thanks to everyone for their help.

Hello Philip,
I am sending you a sample application in which I have placed a TextBlock inside the IndicatorCell to show an asterisk. The tricky part is to name the TextBlock to NavigatorIndicator so that the visual states which handle the visibility will work.
From what I gather from your posts you have managed to show the indicator when you enter edit mode so ultimately the sample should handle your case.
Let me know if you need any further assistance.
