Alex Lee的學習筆記

兩種方法

1.  修改 DataGridViewRow.DefaultCellStyle.BackColor

        private void dataGridView1_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e)
        {
           
            if (dataGridView1.Rows.Count <= e.RowIndex) return;
            if (e.RowIndex < 0) return;
            if (dataGridView1.Rows[e.RowIndex].Cells[1].Value == null) return;
            if (dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString().ToUpper() == "TRUE")
            {
                DataGridViewRow row = dataGridView1.Rows[e.RowIndex];
                row.DefaultCellStyle.BackColor = Color.SkyBlue;
                if (row.Selected)
                {
                    row.DefaultCellStyle.SelectionBackColor = Color.Yellow;
                    row.DefaultCellStyle.SelectionForeColor = Color.Red;
                }
            }
        }

 

2.  修改 CellStyle.BackColor

        private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
        {
            if (dataGridView1.Rows.Count <= e.RowIndex) return;
            if (e.RowIndex < 0) return;
            if (dataGridView1.Rows[e.RowIndex].Cells[1].Value == null) return;
            if (dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString().ToUpper() == "TRUE")
            {
                DataGridViewRow row = dataGridView1.Rows[e.RowIndex];
                e.CellStyle.BackColor = Color.SkyBlue;
            }
        }
