I want to reactivate a thread written by jplanet:

It seems I've done this dozens of times, so I don't know what's different now.

I created an editable grid, very simple, just maps directly to a single table. With the default 3 empty rows now, if let's say you just edit one exiting record and submit, it returns an error message for each of the blank rows that a required value wasn't entered....

Very bizzarre...does anyone know what conditions might cause this to happen? I've made sure that there are no default values in any of the items. Each row consists of one checkbox and two listboxes...

should be a bug in CCS?

The problem is bound to the checkbox. Checkbox in HTTP doesn't have "empty" state. In result, editable grid thinks that some values is entered into the insert row, and will try to validate and insert it to the database.

This is actually not related to .NET and would happen with any application. There is no such thing as empty checkbox (it can only be True or False), therefore your application has no way of knowing which rows are empty. All rows have values, therefore are not empty and are validated. You may need to remove the checkbox or use some custom solution.

it would be possible only if the checkbox won't be visible n the new rows (rows for inserting new content)

anyone accomplished this?
I can't figure out in .NET how you can stop a checkbox from showing in the new rows....
