I am developing a hierarchical radgridview using winform. I am able to retrieve data from the database (bound data). I would like to enable users to add multiple rows in the same radgridview and then save everything to the database. I have developed another radgridview that allows users to enter data. but I want to perform these functionalities into one radgridview.
When I am trying to do that, the system says: " Rows cannot be programmatically added to the datagridview's row collection when the control is data-bound".
Can you help me with this please?
