Question

I’m trying to change color of empty rows in a DataGridView

foreach (DataGridViewRow r in dgv1.Rows)  
if (r.Value.ToString() == "")
//if (r.Cells.Value.ToString() == "") - also trying
r.DefaultCellStyle.BackColor = Color.WhiteSmoke;

but Row has no definiton for Value, and Cells need to be specified by Column.
How can I do this, please ?

Well, you’ll need to check all the Cells. Here’s how you can do that using LINQ:

foreach(DataGridViewRow r in dgv1.Rows) {
    if(r.Cells.All(c => c.Value.ToString() == string.Empty)) {
        r.DefaultCellStyle.BackColor = Color.WhiteSmoke;
    }
}
