OnSaved view refresh

I have attached my object… i can't get "View.ObjectSpace.Refresh();" to work… :<

I'm afraid it is difficult to provide you with a suitable solution without reviewing your implementation. Would you please send me a simple sample with the database backup? I will be happy to help you.
Additionally, I recommend you review the XPO Stored procedures thread where several recommendations are described.

i think my problem is can't get the view instance so can't get "View.ObjectSpace.Refresh();" to work.
Could you provide syntax to get view instance? thx so much in advance

Thank you for the clarification. The View.ObjectSpace.Refresh approach was designed to be used in ViewController. In your case you need to use Session methods inside of the object or ObjectSpace.Refresh method in the ViewController.

thanks for the hints.  I will try again.

Dear Alexey,
I still can't figure out way to refresh the grid in onSaved.  Could you help?  i can't come up with the correct syntax. :<

Have you tried the approach from the Refresh view is not working thread? Please send me a sample project where this issue is reproducible. I will be happy to help you.

Pls check vwt_batch.cs file OnSaved function. thx

Thank you for the sample project. Though it is still difficult to research the issue without a database and knowing what sp_Batchupd procedure is doing, I suggest you move the following code to a separate Action:

C#
DevExpress.Xpo.DB.SelectedData a = Session.ExecuteSproc("sp_Batchupd", new OperandValue(Convert.ToInt32(BatchID)));  
((ListPropertyEditor)vwt_Batch.FindItem("vwt_Batch")).ListView.ObjectSpace.Refresh();  

Additionally, I recommend you try the following code:

C#
DevExpress.Xpo.DB.SelectedData a = Session.ExecuteSproc("sp_Batchupd", new OperandValue(Convert.ToInt32(BatchID)));  
Session.DropIdentityMap();  

Please send me the database backup if the provided information does not help you.

Here is the db for your investigation

Here is the step to replicate my problem

Thank you for the database. I have researched it and found a suitable solution.
You need to move the stored procedure execution to the ViewController, because the OnSaved method is not suitable for this task.  In that case, the following code will work correctly:

C#
DevExpress.Xpo.DB.SelectedData a = (this.ObjectSpace as XPObjectSpace).Session.ExecuteSproc("sp_Batchupd", new OperandValue(Convert.ToInt32(BatchID)));  
this.ObjectSpace.Refresh();  

I have attached a video that illustrates this approach.

ObjectSpace.Committed

Is there any other way that i can do it elsewhere not using controller?  I got many view that are working that way and I don't want too many controllers.

The ExcuteSproc method directly makes changes in the database. That is why the changes will not appear without using the ObjectSpace.Refresh method that cannot be executed from the business object. That is why you need to use the approach with ViewController.

from the video, button for controller is shown on toolbar.  how to hide it?

Also, how to get batchID that was used in onsaved()

This button is not related to your solution. In my video, I do not click it to refresh DetailView. So, it can be removed. Additionally, I recommend you review the How to remove or hide (deactivate, disable) a button ( Action ) from tool bar article that describes how to hide an Action.
As for the BatchID property, you can simply access the vwt_batch object via the DetailView.CurrentObject property as described in the How to: Access Objects Selected in the Current View.

Dear Alexey,
I am very green to programming too. I only know way to get select record in listview using controller as button.
I am still stuck at the syntax to get BatchID in the controller. Kindly help. thx
