GridControl | XML based Grid configuration | Grid library

I need to find what code is causing an entity to be modified. In my .Net Core Winforms XAF EF app When I go into a detail view and click close I get a message asking me to save, even though I have not edited anything.

I added a listener to my ViewController as follows

I have the following non persistent entity

Here is an exemplary code piece:

Model.cs

I'm beginner in using DevExpress tools. I can not find any property, that shows the gridControl's row selections state, to my if statement.

Any suggestion?

Firstly, I have 3 tables in my database:

Then I created a stored procedure to select some column on [TuitionFee ] and [Detailed_TuitionFee ] with StudentID as parameter.

i am trying to implement like the below image.

I have a grid view which has 2 columns in which i am displaying my list.

As you can see in the above image it is showing 175/67 products.

my logic is i am giving my grid view a scroll controller.

I am adding a listener to that controller but i think my logic or calculation is wrong.

below is my code :

I'm working on legacy code and I stumbled upon an issue that got me stuck for a week. I would like to hear others' opinion about it.

The case includes parent - children items: when a parent node is selected, a devexpress.xpf.Grid bound to BindingList children is populated with corresponding data. Say, a row was selected/highlighted within the grid. When another parent node is selected, the children list is cleared, new items are added and they get displayed in the grid successfully.
Actual behavior: The previously selected row will remain selected.
Desired behavior: To clear selection when the content is updated.

Concern 1: ItemsSourceChanged will fire once at the first loading, but not for every update . I believe it's because the items source isn't changing per se, the object reference is still the same, but the content is updated and there's no ItemsSourceUpdated that I could find. Also, TargetUpdated only fires once at the first loading too despite having NotifyOnTargetUpdated set to true and Child implementing INotifyPropertyChanged.

Concern 2: When updating the children list, the ListChangedEvent was suppressed to avoid firing for each added item. RaiseListChangedEvents is set to false, some business logic happens, then RaiseListChangedEvents is set back to true followed by ResetBindings() to fire the event. When this suppression is removed, the selection is cleared as desired. I suppose there's something getting disabled but not enabled again?!

Concern 3: For the very first load of children into the empty tableview, the first row is selected by default. This can be stopped by setting AllowInitiallyFocusedRow to false in XAML. while researching this issue, I found KeepFocusedRowOnUpdate which can be set to false to achieve the desired behavior. However, KeepFocusedRowOnUpdate isn't available for the GridControl being used and I couldn't find any equivalent. What struck me is that there are many threads on Devexpress support center for achieving the opposite, people want to keep/retain/preserve previous selection. that made my search even more harder.

Concern 4: The VM holds ReadOnlyCollection SelectedChildren not explicitly bound to the view but Caliburn micro is used so a lot of naming convention is at work I suppose. I suspected the readonly was keeping the selection from being cleared but when removing the suppression as mentioned in point2 the selection gets cleared indeed. Unless it's a very specific case combination between these two?!

Any ideas, pointers, or similar experiences are appreciated.
PS: There's a lot of code involved so I didn't know which would be useful to add here. If there's anything specific you think would be helpful to add, please let me know.

I have found this link. This link explains how to get row over mouse pointer in GridView but I have not found anything about how to do this for GridControl.

Is there any ideas?
