Have you seen the ColumnFilter extension? This would be an easy way to add filtering functionality to your DataGridView.
Check this out: https://wisej.com/blog/columnfilter/
For a list of full extensions, check out our GitHub repository: https://github.com/iceteagroup/wisej-extensions
You can find a demo of the ColumnFilter extension here: https://github.com/iceteagroup/wisej-examples
Alternatively, if you don’t like the ColumnFilter extension you can add a new row at index 0 in your DataGridView and add an event handler for CellValueChanged and EditingControlShowing to show an appropriate filtering control (i.e., ComboBox, TextBox, etc.) and handle the filtering yourself.
Let me know if this helps!
