ASP.NET 2005 issues with creating object data adapter in design view

normally when i create a table adapter in design view, i will have this list on the last step
Generated SELECT statement.
Generated INSERT statement.
Generated UPDATE statement.
Generated DELETE statement.
Generated table mappings.
Generated Get method.
Generated Update methods.
How come when i use Authors Table in Pubs sample database to create a table adapter, the line "Generated DELETE statement." is missing? (which means that the delete statement wasnt generated)

It is because:
there was no PK set in the author table when i took it out of the Pub database
now with a defined PK (the AuthorID), all the statements were generated correctly.
The designer just didn't provide enough information explaning why some of the statements havn't been generated. maybe it's something need to be improved....

ASP.NET AJAX, not let autopostback items cause page reload when the postback occurs

e.g. on my form, clicking on the navigation items (or a dropdownlist control) on the left of screen will filter/refresh the gridview on the right hand side, how can i achieve this using Ajax and not let the navigation items (or a dropdownlist control) to reload themselves? (only the gridview refreshes) the dropdownlist has already been placed outside of UpdatePanel. the whole page reloads because the dropdownlist is "autopostback". I found 3 lines of code that helped me to stop the whole page reload:

This can also be achieved by setting "Triggers" property of the UpdatePanel in design view

any ideas?

i need to write up a research proposal this semester, what are the hot topics related to information systems at the moment? hope someone can help me out~

I am back!

happy chinese new year! now i am back to work & study, wish myself great achievement in 2007!
