From your description, you have an ASP.NET 1.1 page that display some
database record through DataGrid control, and you'll use a popup page to
add new record or editing existing record. Currently, you're wondering how
to make the added or changed record info passed to the parent page so as to
update the DataGrid, correct?
According to this issue, here are some of my understanding:
First, when adding new row or editing exist row, if you want to get the
updated/inserted new values, you should get the primarykey identity of the
certain record so that you can perform query to get the updated value
later. For editing row, this should not be a problem. For new inserted
record, the DBMS engine should provide statement for retrieving new
inserted record's identity(such as the @@Identity of SQL Server) or you can
manually control the PK of table record.
Here is a former thread discussing on retrieve new inserted
value(sqlserver)'s auto generated identity:
#Retrieving Identity Values after DetailsView Insert More options
Second, after you get the updated value, how would you like to update the
main DataGrid's displayed data? ASP.NET template databound controls
populate data(rows) through databinding. Therefore, if you want to update
DataGrid's UI, the expected ways is to redo the databinding on DataGrid to
the new datasource. Do you think this is what you want?
In addition, for AJAX, so far ASP.NET 1.1 hasn't provide sufficient
built-in support on it. Do you think postback the page to updating the
DataGrid is acceptable?
