I have dropdownlist as well as TextBox in GridView on which event is bind. Normally when we select quantoty from the dropdownlist, it simply multiplies with the adjacent cells of the row to the next cell.
Since the entire GridView is inside the Updatepanel. Its get refreshed every time I change the dropdown or textbox's data.
But I like to have update panel row wise only. Is it possible?
I tried wrapping these controls (DDL and textbox) exclusively with UpdatePanel, but it didn't worked. I think it is being important for me as Grid is long and even each row in having a Thumbnail binded and which is coming from database blob with HttpHandler.
Hope yo have early replies.
Thanks & Best Regards

Many Thanks for your reply.
It is in the updatepanel. The problem is my loading taking time as per the calculation I am doing. So I thought if it would be based on GridViewRow then it will update only relevant row not the entire Grid.

I don't suggest you do that like you said. But you could try ASP.NET AJAX extender HoverMenu. For details, please refer to:
Let me be more specific and more simple, what I need is just this:
When I select a value from dropdownlist it takes time to update even I just have very simple calculation and no communication to database is there. I suspect that my gridview is having thumbnail column also which is coming from blob using httphandler. entire
image in the column gets refreshed when I select from dropdown.
It is taking time? Don't know.

Ok, I will try this and revert. May be it is similar of PopControl of Devexpress which only I worked before this.
