    Hi,

     

    I noticed that it is impossible to use multibinding on IsReadOnlyBinding of GridViewBoundColumn.

    As I have several sources for my binding I really need multibinding. Do you plan to add the functionality in the future?

    Hi,

    Due to the better performance of member access expressions over the WPF DataBinding mechanism, we rely entirely on them in the RadGridView's data engine. Currently, the data engine implementation relies on translating the defined bindings to lamnda functions that are used carry out member access. Modifying this core logic, without major modifications would be impossible, so we do not plan to introduce such a feature in the future. Would it be possible for you to use a calculated property that aggregates these sources' data into a single value and use a Binding to it?
