postback problem

i have asp.net web page,on page load i create a simple html table with fixed no of rows and no of columns and their names are determined dynamically.now i have few javascipt functions for adding a row to table,for adding another column to table and for removinga row from table.

also i have a asp:button on click of which a xml file is generated from the data filled in by user in the table.but as soon as i hit the asp button to generate xml all newley added rows and columns are deleated.Is it possible to call a server side function without posting the page back.

Yes, it is

take a look at this article about client scripts callbacks:

Sorry man,

I haven't put the client scripts callbacks into practice yet too.

I was going to use them to create a dynamic progress bar, but then i've decided to use the ajax update panel.

It was much faster and cheaper.

Previous rows display when a new row add in GridView (in UpdatePanel) after hitting enter

I am having a problem in GridView using UpdatePanel. I have UpdatePanel which contains a GridView. When I enter rows in GridView and refresh a page it remove rows from Grid and if I enter again it shows only new entered row, works fine.

But when I enter few rows in Grid then click on address bar hit enter on it, it removes the rows from Grid and when I again enter a row again then it shows new with previous rows.

Can anybody tell me where am I doing a mistake.

Thanks in advance.

It works fine in debug mode but when I deploy the application on server, it shows previous records with new record.

Any idea?

Thanks in advance.
