Scenario
Suppose we have implemented calculated properties as described in the Make a Property Calculable article and want to achieve the effect shown in the attached video (ExpectedResults.swf).
Problem description
Currently, if we even mark this property with the ImmediatePostDataAttribute, the changes will be immediately reflected only in detail view, but not in the edited list view. This behavior is caused by WinForms XtraGrid specifics - it does not post the editor's value to the datasource until the cell's editor is closed or loses focus. To support this, we need to write a VewController that will handle the changes of each cell in the row those column property is marked with the ImmediatePostDataAttribute.
