OnEditEnded PropertyGridEditEndedEventArgs OldValue and NewValue always have old values

[Greg Horvath]

When OnEditEnded is fired the e.OldValue and e.NewValue don't seem to have the correct value. They both always have the old value. I need to be able to see if the value has changed to update the a dirty data flag in my application. Is there any way to do this? Thanks

Hello,

I have prepared a sample test project, but I did not have any success in reproducing this behavior. I am attaching it for your reference. Can you please confirm whether you can notice any related difference between your approach and mine?

This approach is essentially what I am doing and I am seeing the same behavior in your sample project. I select the first row in the grid view, then go to the Name property in the property grid. I change the value from "Liverpool" to "Test" and in the event handler the old value still says "Liverpool". You can see this in the immediate pane in the screen shot below.

Looks like my pasted image referenced in last reply did not show up. It is attached.

Hi,

Please excuse me for the delayed reply. I am afraid that I am still not able to reproduce the issue. The only approach that results in the same OldValue and NewValue on my side is when the edited property is not changed. I guess that I am missing something, so I am attaching a video.

I noticed from your video that your navigating using the mouse only. E.g. clicking the next cell when you finished editing. The issue appears to only happen if you tab off the current cell being edited.

Hi,

You are right. Tabbing out results in raising the event with wrong arguments. I am adding 1000 Telerik points to your account in accordance to this bug report. We will do our best to fix it with the incoming Q1 release.
