I need a PredicateBucket with a PredicateExpression like that:

(condition1 OR condition2) AND condition3

I wrote something like that:

filter.PredicateExpression.AddWithOr(condition1);
filter.PredicateExpression.AddWithOr(condition2);
filter.PredicateExpression.AddWithAnd(condition3);

But this way I get this unwanted result:

condition1 OR (condition2 AND condition3)

How can I achieve the first option?

You need to wrap the sub expression in another PredicateExpression, like so:

PredicateExpression mPE = new PredicateExpression();
mPE .AddWithOr(condition1);
mPE .AddWithOr(condition2);

filter.PredicateExpression.AddWithAnd(condition3);
filter.PredicateExpression.AddWithAnd(mPE );

or words to that effect.

ok! Thanx!
