You haven't included enough here to say for sure. What I see is that the TableView is not connected to the output of your query. A TableView requires a TableProvider. This is set in the Properties grid and that needs to be a LookupTable. Your query outputs a DataTable but it is not assigned to anything.
To see if your query is working, extract a proxy from the query result. That should be a DataTable. Extract a proxy from the Rows property. That will be a Rows Collection which should have a Count property.
Thank you for your reply. A TableProvider of the TableView is oleDbQuery1 which has CommandText, "SELECT * FROM testin.csv". I am expecting a Count property of the TableView has a number of rows retrieved by oleDbQuery1, but a result returns 0. Would TableView have a count property from a result count of a TableProvider?
Please find an attachments, oleDbQuery1 and tableView1, showing property settings of the TableView and OleDbQuery.
