Can the CustomValidator be used to simply report unexpected errors,
without requiring Client/Server validation? To explain, say you had a
simple text box and button that did a Full-text Search of a Catalogue
in SQL. Malformed search requests can generate a variety of errors,
which I simply want to catch, set the CustomValidator's IsValid method
to false and assign the ErrorMessage to the CustomValidator's Message
property. For example:

This is how you use the customvalidator control in any INamingContainer
interface control (Datagrid, DataList, DataRepeater, etc).
1. In the ItemTemplate, place your customvalidator
2. Set the OnServerValidate property of the customvalidator
3. Get reference to the Data Item object
(For DataList is DataListItem, for DataGrid its DataGridItem)
4. Get reference to any controls needed for validation
5. Perform the validation

Hello
Here's my basic problem:
On my asp.net form page I have a DetailsView (default mode=edit) bound
to a AccessDataSource control. Users can successfuly update a databound
template field, but I wanted to add a custom validator to check that
the account number they are entering exists in a table in the Access
Database.

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
