Set Data/Perform Custom Operation Before Automatic Insert/Update/Delete

[Peter]

How do I set data and/or perform custom operations when using the "AllowAutomaticUpdates" (Inserts/Deletes) property?

I note the "ItemInserted" and "ItemUpdated" events occur, but what about "ItemInserting" or "ItemUpdating" etc?

Hi Peter,

The automatic data source operations only work when binding the grid to a declarative data source using the DataSourceID property of the grid. You must configure the data source so that it supports the automatic operations. You also need to set the DataKeyNames property of the table views in the grid so that the insert, update, and delete operations perform as expected. Check the following help documentation which explains more about this.

Thanks,

I understand - but is there any event where I can interact with the data before it is saved? E.g. set some additional data behind-the-scenes?

Hi Peter,

You could use ItemInserting/Updating server event if it suits your specific scenario.

Generally, I could suggest you to use ItemCommand event and use e.Canceled on some condition. Then after performing some logic, you could enable the condition and fire an Update/PerformInsert command as demonstrated in the following topic:

I hope this will prove helpful.
