I can not find out why u use the BlogManager to perform the delete update and insert , instead of invoking the right method in your ObjectDataSource.
I must admit it didn't work for DataList but for a GridView it worked like a charm.

If u have any idea why the DataList do not fire the delete, insert or update i would be happy to hear.

Thanks.

Hi Usha,

We can also specify UpdateMethod, DeleteMethod and InsertMethod to our ObjectDataSource control, but I prefer to invoke these methods in the respective events as it gives me complete control over validations.

Also when we specify the methods declaratively, the page parser has to understand and invoke the respective methods through reflection, this is an overhead and we have to pay performance penalty.

So I generally specify the SelectCommand to the objectdatasource control and for other operations I use the respective events.

Coming to the problem of events not firing, this could happen if the commandButton/LinkButton/ImageButton is not placed in the proper template.

For example in order to fire UpdateCommand you will have to place the button in the EditItemTemplate.

Hope this helps you...

It did help. It didn't fire because i add the delete and edit not in the edit template as u said.
Thanks for your reply.
