A particular Update panels refeshes the UI partially i.e. the part that is inside that update panel.

Update panels can have has something called 'Triggers' associated with them.

From what you need:
if you need to update the textbox values in UI then the update panel having those textbox values need to be triggered for an update.

You can use those button fields added as triggers to the second Update panel. Then, whenever those button fields are used, it will trigger the other update panel and thus update the textbox values.

A page can host several UpdatePanels. By default, when one UpdatePanel on a page updates, the other UpdatePanels on the page also update. Sometimes that’s what you want, but more often than not, you don’t need every UpdatePanel updating in response to other UpdatePanels.

You can be selective about which UpdatePanel instances update (and when) by setting the UpdateMode property of each UpdatePanel control on the page to "Conditional." Then, when one UpdatePanel updates and calls a server-side event handler, call UpdatePanel.Update on the other panels you want to update. This reduces the load on the server by reducing the number of controls that render, and it reduces the volume of data in the response because UpdatePanels that don’t update don’t add anything to the response.

I had a similar problem.
Putting textboxes inside the UpdatePanel will work for you.
But I am not sure if its a correct solution. It's just a work around that worked for me.

I am looking forward to hear from other people for a better solution.. :)

You said that "but problem is that values are comming in the text boxes"

So What is your problem exactly? you don't want values in textboxes?
