Add rows to datatable after page post back

[srinivas]

HI,

I have 4 text boxes and one button in my page. When ever I
fill the text boxes and click the button the data should be add to a
datagrid with out inserting a record in database. For this I used
datatable to insert the records but when ever I click the add button my
aspx page is submitting. When page submits new datatable instance is
creating and I lost old data. How can we keep old rows and ad new
datarow in data table. Sorry for my english. Please help me in this
regard
Thanks in advance

If you don't want to reload the table, you should make it persistent. You
can do it in a session variable. IsPostBack property tells you if you are in
a postback that you will know you need to restore the datatable from the
session variable rather that load it from the database.
