Solution 1

NumericUpDown does not accept string values. See: Set and Return Numeric Values with NumericUpDown Control - Windows Forms | Microsoft Docs[^]

Change your code as follow:

C#

numericUpDown1.Value =  (int)dataGridView1.SelectedRows[0].Cells[5].Value;
numericUpDown2.Value = (int)dataGridView1.SelectedRows[0].Cells[6].Value;

Still has an error it says "Cannot implicitly convert type 'object' to 'decimal' "

Cells[].Value returns an Object, so you have to cast the value back to the type youi need:

numericUpdateDown1.Value = (int)dataGridView1.SelectedRows[0].Cells[5].Value;
