Hi,
Thank you for sharing your feedback. Currently,
RadGridView does not suggest such a built-in functionality.
In order to detect the Ctrl + F combination and show a search window, I can suggest you is to handle the KeyDown event of the grid.
For example:
The content of the control may be a custom user control that will be responsible for searching the items. As an example you may take a look at this blog post for a reference. In your case the searching TextBox should be defined in your custom user control.
