Posted by Rey Dacoco in

This error normally appears when you have selected enable deleting and enable editing GridView or FormView task options and you try to delete or update a record at run-time. This error can be fixed by converting the SQL statements in the InsertCommand and AccessCommand to Jet SQL statements. To be able to clearly understand the solution, let us start from the beginning:

6. Click View>Solution Explorer>Right-click your website solution name, Select Add Existing Item. Locate you dbnames access database file>Add. The solution explorer should now look like this.

9. Click Next. Click test query to view the result of the sql statement then click finish.
10. Click the GridView task button(>) then check enable paging, enable sorting, enable editing, enable deleting, and enable selection checkboxes.
11. Click the View in Browser button. If you are prompted to save changes to your website, just click the yes button.

13. To solve this problem, click the Source tab to view the source code of your website. Look for the following lines:

14. Delete the OR logical operators including its respective conditions, your code should now look like this:

15. Click the View Browser button and try clicking the Deleting or Record value. This time you can delete or delete a record value without getting a ““No value given for one or more required parameters”
