Hi,
The property changed event is triggered multiple times when a property is changed. Please check the attached project for sample.
Please let me know the solution so that the event will be triggered only once.
Regards,
Ramesh Durai
Hello Ramesh,
Thank you for contacting Infragistics. I've tested out our application and I was not seeing PropertyItemValueChanged firing twice nor the members in your view model in 2016.1 build 2134 (latest service patch). I've attached a sample solution that you can run using our latest service release assemblies. Please let me know if the application reproduces the behavior you've found. If not please let me know which build you are using.
If you are not currently using the latest service release and would like to upgrade please read these instructions.
The latest Service Release build is available at Infragistics.com.
1. Go to https://es.infragistics.com/my-account/keys-and-downloads. You may be prompted to log in with your username and password.
2. You will see a list of all of your registered keys. Select the version of NetAdvantage you are interested in.
3. Select the "Services Releases" tab on the bottom.
4. Click on the item you want to download.
Let me know if you have any questions regarding this matter.
I am using the latest service release(2016.1 build 2134) and still having the same issue. There is no sample solution in your post.
Yes, I am seeing the message box twice for each property change. This issue also occurs in the build you've shared. I have just downloaded your code and uncommented the messagebox line.
Environment:
IDE: VS Professional 2012
OS : Windows 7 Enterprise 64 bit
Ramesh,
Thank you very much for following up. Since I was unable to reproduce the behavior I will begin building a virtual machine tailored to your environment in an attempt to reproduce this. In the meantime please provide a video demonstrating the issue occurring and upload it here, if possible. I will inform you as soon as I begin testing.

I've reproduced the behavior, but it's only been happening with text editors using strings and integers. Checkboxes with Booleans don't seem to affected. I am currently in a discussion with my team to determine our next step of action. I will follow up early next week regarding my progress.
Let me know if you have any questions.
