C# – Newly added row to DataGridView not showing

cdatagridviewormsubsonic

I have a DataGridView that allows users to enter new information. Using subsonic I Save the new info to the database. And this works correctly. My problem is that after the Save is done the newly added row disappears from the grid. I tried to Reload the form, but I get the following error:

Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.

I don't think the issue is subsonic related. Does anyone know why the newly added row disappears?

Thanks

The reason was that I broke the binding connection by using ".ToTable()"

kek444 - thanks for the reply. Don't think that will help. I'm not using _CellEndEdit but instead using _RowValidating. I've also tried _RowLeave and others. I don't really want to reload the form - I just don't know why the newly entered values disapper when the row loses focus.

C# – Why is the bound DataGridView throwing an “Operation not valid because it results in a reentrant call to the SetCurrentCellAddressCore function” error

The exception is raised by the DataGridView in order to prevent an infinite loop from occurring. The cause of this is usually one of the following:

Changing the active cell while an operation is being performed on the currently-active cell
Beginning, ending or cancelling edit mode while a cell edit is already in-progress
Any other operation that results in the active cell being changed while the DataGridView is still using it

Have a look at your handler for the CellValueChanged event and make sure you are not doing any of the above within the handler.
