Michael #2 Re: Refreshing datagrid
Just call the .DataBind() method of the datagrid in the page you want to
display the new data. Your datasource will have to be updated with the new
info though. If your datasource is a dataset, this should be pretty easy
and not involve going back to the database and requerying.

QUASAR #3 Re: Refreshing datagrid
Why you don't use the same page to add the record directly to the datagrid?
If this can be ok for you the ASP.NET WebMatrix has a good example for this
in the new file template named "editable
data grid" that come with the program...
There also is another my post of today where I have also attached the
file...

dada #6 refreshing datagrid
Hi!
I datagrid (dataset) that I fill from webservice. When I add new row
to dataset, it`s ID it is writter on SQL server ok, but in datagrid
it gets last id in datagrid +1, untill I take edit and datagrid
refreshes from server and gets proper ID. For example, if I add new
record that has id 2 on server and delite it (now next row has to have
id 3), and again add new record in datagrid it shows id=2, but on
server is id=3 (correct).
So, I am asking you how to refresh my datagrid after adding new record
in the sime step.
my code html and aspx.cs is bellow.
Thank you,
Davorka
