Hi guys,

 

At the moment i have made a filter on a field of a ServiceDataProvider (based on a Rest service), the thing is that it is case sensitive based.

So for example i have a table called currency, which has a description and a decimals field.

When i am filtering on a description with the input called Dollar, it ony returns exactly the records which has dollar with a capital letter.

My question is how could you change the behaviour of the filtercriterion, that it also returns the same records without using capital letters?
