What I would like to add in my Weight field that I show you below
A word, that is to say for the values that are in ZERO "0" that in the gridview is visualized as NA and if it has a value different from ZERO, that conserves the value. I do not know if I explain myself. I do not have an intermediate code, to present it, the value is of a decimal type. I await your help. thanks
Without knowing how you retrieve your data or how you store it in the datagridView, what I can think of is that you create a method that runs through all the rows you have and compare the value of your column Weight, if this is equal to 0 you replace it with "NA".
Something like that would be:
public void remplazaCero()
{
foreach (DataGridViewRow dRow in DataGridView1.Rows)
{
if (dRow.Cells.Item(2).Value == 0)
dRow.Cells.Item(2).Value = "NA";
}
}
2 is the index of the column you are going to compare (start counting from 0)
Finally you send your method calling where you load your DatagridView, it should work.
