Ask the datagridview control cell editing and verification issues!

dch007

After the edit event of the datagridview control occurs, how can I write code in the validating event to determine whether the input is wrong? When I add a cell, I need to enter single-precision or double-precision data. As a result, I entered a letter. How can I judge the input error? Because there are many types of data, and the type of the field value of each field is not necessarily the same, I cannot judge one by one. Is there a general way to achieve such a function? Can you give me an example?
Very anxious, please help to see, thank you in advance! !!

It seems that datagridview cannot be validated. You need to find the edit line of datagrid, and then judge it in the background
