I am using the following code to filter on a textbox value using the BindingSource.Filter function.I thought this was the right code based on my many searches.
When do a debug, it shows the correct value which is "432360ac-ac35-4101-8d46-f2cbd5b5dc52.There are spaces in the end of this value and it is exactly the same in the SQL database with the spaces. ValueID is a column in my SQL server.

Although I obviously need it to work for multiple values from my SQL server.
