If you can't read my code, try converting it here[^]

MyBindingsource.datasource=(From t in context.Mytable Select t).Tolist

Mybindingsource.Current.vl1=25

If I use

SQL

MyBindingsource.datasource=(From t in context.Mytable Select t).Tolist

and after :

Mybindingsource.Current.vl1=25

everything is ok.
