C# Update fields belonging to the Id in the query string
<p>I m a newbie to C# and Ive got this doubt please help.
I have these 2 webpages  lets call them pageA and pageB .PageA has got a table(used DataGrid) displaying all the fields of a table in sql server ,it has got an additional edit column which displays a link to PageB, the url for pageB has got a query string which contains the ID of the product that is to be updated .In PageB i have got an update form. The form fields of which is already filled (i.e im retrieving data using the ID from the query string using "select").This pageB has got a button which is supposed to update the fields that were edited in this page and store them back to the server . 
In pageB :the Page_Load() is where i save the ID to a variable (VarID) and i call the method fill_data_fields() which does the "select" and fills the fields .I ve also got the update_click() which is called when i click the button on pageB it is in this method I ve written the code to update the fields in database .
The PROBLEM is ,that the method update_click() is never called when i click the button.</p>
