When you will choose from dropdownlist and will postback to make changes, you will need to do the same what u just did above.
Means adding those columns again (but this time in the order mentioned in your dropdownlists)
Hope this helps..

Don't. If you want PostBacks to work properly, they need to be added in the Init Phase. Use Page_Init if you can.
Now,based upon the value selected from a dropdown I need to change the order in which the columns arde displayed.Is it possible.
GridView will build rows during DataBind. The Cells will be ordered in accordance with the Columns. So if you order Columns right, and then DataBind, that should work.
One snag, though. As said, to make PostBack work properly, you need to add the Columns in the Init Phase. The order in that will have to match that of the last request. And you will not have the value of the DropDownList available at that time. Also, in
the Init Phase ViewState may not be available for use yet. Not sure how I would go about this. It's not easy.
