Hmm... i think i didn''t give you enough details for my senario.
I''ve created a custom ProgressBarAdv name "MyProgressBarAdv", this progress bar is inherit from the original ProgressBarAdv with an extra property in it. I''ve attached the codes together with this message.
What i want to do is, i want to replace the original "ProgressBar" or add the my custom progressbar to the GridCellType list which i can use my custom progressbar on a GridDataBound grid..
