Yes and you don't know the difference between an int and a string? What is the question?

You convert the string to an int. Should be obvious, isn't it?

Hello,

you can only compare what is comparable. In this instance it should be 2 integers

The Value property of a Cell is an object and you need to convert it to an integer.

Convert.ToInt32(row.Cells["diff"].Value)>1

If you are unsure what the content of the type cell is you can find it looking at the property

ValueType

See here for details:
DataGridViewCell Class (System.Windows.Forms)[^]
