HI,
I have hierarchical grid and binded a observablecolleciton<Student> with that grid. When record initialized i
expanded the record using IsExpanded property.
Now i am changing the one property in a student object. The grid not showing the current value.
(I applied INotifyPropertyChanged). If i am collapse that node and expanded again in the sense,
it shows the current value. After expanded if we change any property in student object. It shows
immediately. Not only the property changing, the DataRecordPresenter also i was unable to take
on that time. I can get DataRecordPresenter once collapse and expanded (I think some kind of refresh).
(I used DataRecordPresenter for change the background color).
In previous versions (8.2) grid it is working immediately. But now it not happenning.
I installed hotfix also.
I most dependent of INfragistics control. Please *** me to solve this issue?
Hello,
I am sorry, I did not understand very clearly the sequence of actions you perform. Do you expand and change value of the records in the InitializeRecord event or you just expand them? Which event you handle to make changes to the Student object?
I tested your scenario -- expand and change values of the Student object ( both in parent and child records ) and the grid reflects the changes immediately. I believe the issue might be coming from the INotifyPropertyChanged interface or in the event you are trying to change the value of the record.
Please give me more detailed information about the events you use and their source code.
If it is possible, attach a sample project to your next post that illustrates the problem.
Regards,
Alex.
