Question

my VB programm works fine, then I had to add 4 new boolean fields to a table in Access2010. I updated the datasource and the preview of the dataview works fine (Visual Studio 2019). But unfortunately my DataGridView doesn't work anymore. I deleted the DataGridView and created a new one with the ame name but it doesn't help. I still the message : "No value given for one or more required parameters."

What can I do ? I checked the columns name and everything is ok ?
