When users want to delete a record, they must first find that record in the database. Accordingly, you need a search page to work with the delete page. The user enters search criteria in the search page and selects the record from the search results displayed in a DataGrid. When the user clicks the record, the delete page opens and displays the record in an HTML form.
For instructions on creating a page to search for the record to delete, see Building a database search page (ASP.NET).
After creating the search page, the next step is to add delete buttons or hyperlinks to the DataGrid on the search page. See Creating delete links on the search page (ASP.NET).
