Progress bar Inside Gridview

[haytham hosny]

Hi

I have a gridview binding from the databse , i added a select column and a progress bar (through Gridview Data column)
I managed to insert a telerik progress bar inside my gridview , Now i want when i press a button outside that grid , a loop is made on the selected rows and the progress bar of this selected cell is only changing value ,once the loop get to the next row , the previous row progress is 100% and the next row is to be processed and so on

How can i achieve that ?

Below is my Gridview

Thanks in advance
