Stop deleting a Row in the Changing event within a DataGrid

[Benedikt Eckhard]

Hi!

I wan't to prevent a user to delete some Rows showed in a DataGrid.

I registered for the DataTable.RowDeleting event and tried to throw an
exception when deleting occours but is forbidden(as proposed in the msdn).

Problem: Nobody catches the error, so an application Exception gets shown to
the user. How can I catch the exception or prevent deleting a row in an
other way?

Thanks in advance

yes, if you are using datatable/dataview as a datasource of grid.

you can make

dataview.allowdelete = false. or
datatable.defaultview.allowdelete = false

that will prevent to delete a row from datagrid.

thanks for the answer!

I don't want to prevent deleting generally, but based on some conditions. so
using the data view isn't really a good solution for me.
