    Thanks Emanuel. This time it's working 100% sure. The problem is (or maybe is a misunderstanding mine) if you read in CellFormating e.cellelement.tag is nothing but however if you read
    e.cellElement.rowInfo(e.cellElement.columnIndex).Tag (If I'm mistaken someone to correct me but it's the same cell (OK?) so it should have the same value in Tag property) gives the value I'm expecting (true or false).

    Thanks again.

    Hello again LLC,

    It was my fault because i should have attached an example but lately I've been extremely busy (sorry again).

    The thing is this, the CellElement is not the same thing as the CellInfo, please take a look at this article, or this more detailed article for further clarifications about the GridVirtualization engine.

    Hope this helps, if you have any other questions or comments, please let me know,

    Best Regards,

    Thanks Emanuel. No problem. So they aren't the same object, that explains it. I didn't read enough well the articles the first time you and Richard told me about them. After this fight I understand better radgridview virtualization and its implications.

    Thanks again.

    Hello Bashir,

    Thank you for writing.

    Yes, the event is fired several times. However, if you are only setting the cell styles in it there should not be any performance impact. Could you please share the code that you are using in this event? Are you performing any time-consuming operations in it? 

    I am looking forward to your reply.
