problèmes de formattage de rangée dans un DataGridView

Bonjour,

J'essaie seulement de formatter une rangée selon que a valeure d'une colonne spécifique soit plus grande que 10. J'ai essayé plusieurs méthodes mais je n'y arrive pas.

1ere méthode:

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
 
 
DataGridViewCellStyle highlightCellStyle = new DataGridViewCellStyle();
            highlightCellStyle.BackColor = Color.Green;
            highlightCellStyle.ForeColor = Color.Yellow;
 
 
foreach (DataGridViewRow row in dataGridView2.Rows)
            {
                if (Convert.ToDouble(dataGridView2["CAP", row.Index].Value) > 10)
                {
                    foreach (DataGridViewCell cells in row.Cells)
                    {
                        cells.Style = highlightCellStyle;
 
                    }
                }
            }

2e méthode

9
10
11
12
13

DataGridViewCellStyle highlightCellStyle = new DataGridViewCellStyle();
            highlightCellStyle.BackColor = Color.Green;
            highlightCellStyle.ForeColor = Color.Yellow;
 
for (int a = 0; a < dataGridView2.RowCount; a++)
            {
                for (int b = 0; b < dataGridView2.ColumnCount; b++)
                {
                    if ((b == dataGridView2.Columns["CAP"].Index) && (Convert.ToDouble(dataGridView2[b, a].Value) > 10.0))
                    {
                        this.dataGridView1.Rows[a].DefaultCellStyle = highlightCellStyle;
                        this.dataGridView2.Rows[a].DefaultCellStyle = highlightCellStyle;
                        this.dataGridView3.Rows[a].DefaultCellStyle = highlightCellStyle;
                    }
                }
 
            }
