winform datagridview更改选中行中选中单元格的背景或字体颜色

Question

RT，想在datagridview中选中某一行数据的情况下，将鼠标选中的单元格颜色突出显示，请问能不能实现？
一开始使用
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Selected)
            {
                DataGridViewCell aa = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
                aa.Style.ForeColor = Color.Red;
                aa.Style.BackColor = Color.LightGreen;
            }
        }
只能实现在不选中改行的情况下颜色突出显示。但是在选中的情况下，选中颜色会将其盖掉，看不出差别

Answer 1

dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Red;

Answer 2

private void SetColor()
       {
            if (dgv.Rows.Count > 0)
            {
                for (int i = 0; i < dgv.Rows.Count; i++)
                {
                    if ()//变色条件
                    {
                        dgv.Rows[i].DefaultCellStyle.ForeColor = System.Drawing.Color.Red;
                    }
                }
            }
        }
加载完数据以后，调用上面的函数

Answer 3

       {
            if (dgv_Name.Rows.Count > 0)
            {
                for (int i = 0; i < dgv_Name.Rows.Count; i++)
                {
                    if (Convert.ToString(dgv_Name.Rows[i].Cells[str_ColumnName].Value) == "1")
                    {
                        dgv_Name.Rows[i].DefaultCellStyle.ForeColor = System.Drawing.Color.Red;
                    }
                }
            }
        }

Answer 4

sorry，不知道是不是我没表达清楚，请试试看选中的情况下：如图：选中行的情况下，选中单元格凸显其他颜色

Answer 5

你试试看在那个属性rowtemplate里的，打开DefaultCellStyle，里面有SelectionBackColor和SelectionForeColor

Answer 6

有没有rowPrePaint事件？
        private void dgv_RowPrePaint_1(object sender, DataGridViewRowPrePaintEventArgs e)
        {            dgv.Rows[e.RowIndex].Cells["A"].Style.SelectionBackColor = Color.Red;
        }

Answer 7

thanks,我也刚刚试出来
public DataGridViewCell dgvc;
        private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            if (dgvc != null) dgvc.Style.SelectionBackColor = _color;
            if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Selected)
            {
                DataGridViewCell aa = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
                //aa.Style.ForeColor = Color.Red;
                aa.Style.SelectionBackColor = Color.Red;
                dgvc = aa; ;
            }
        }

Answer 8

 private void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
        {
            dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.SelectionBackColor = Color.Red;
        }

Answer 9

参考了下   在mousedown 效果会更好
