Question

I have a datagridview made up of multiple rows and columns.
I want to iterate through each row and check the contents of a specific column.
If that column contains the word “NO”, I want to change the forecolor of the entire row to Red.
Here is an attempt at some code so far but It’s certainly not working, starting to wonder If I need to iterate over every cell?

CODE:

foreach (DataGridViewRow dgvr in dataGridView1.Rows)
        {
            if (dgvr.Cells["FollowedUp"].Value.ToString() == ("No"))
            {
                dgvr.DefaultCellStyle.ForeColor = Color.Red;
            }
        }

Answer 1

public void ColourChange()
    {
        DataGridViewCellStyle RedCellStyle = null;
        RedCellStyle = new DataGridViewCellStyle();
        RedCellStyle.ForeColor = Color.Red;
        DataGridViewCellStyle GreenCellStyle = null;
        GreenCellStyle = new DataGridViewCellStyle();
        GreenCellStyle.ForeColor = Color.Green;


        foreach (DataGridViewRow dgvr in dataGridView1.Rows)
        {
            if (dgvr.Cells["FollowedUp"].Value.ToString().Contains("No"))
            {
                dgvr.DefaultCellStyle = RedCellStyle;
            }
            if (dgvr.Cells["FollowedUp"].Value.ToString().Contains("Yes"))
            {
                dgvr.DefaultCellStyle = GreenCellStyle;
            }
        }
    }
