Hey,
Thanks for the reply, but I do not believe your assessment is correct. Excel behaves by reading off the row number, column number, and then the cell content.
The GridControl simply reads off as, "List" and then no further feedback is provided by the screen reader. This is most certainly not in any way similar to how Excel performs.
As a note I am using NVDA for my screen reader. If you were using Window's Narrator to test please use a more appropriate screen reader; due to the gross inadequacies present in the Window's Narrator no one actually uses that in a commercial environment.
