You can add a search box in the grid toolbar that lets the user type their query and the grid will look up all visible string columns with a case-insensitive Contains operator, and filter them accordingly. You can change the filter delay, and the fields the grid will use - see the Customize the SearchBox section below.

I have an int and a string field and would love to be able to let the user search in both at the same time.

Workaround is now:

public int number {get; set;}

public string numberString => number.ToString();

public string name {get; set;}

But I would love to see it without the need to use the numberString
