更改 DataGridView 的行背景颜色

Question

我搜索了很多，找到了一些在数据网格视图中更改行背景颜色的方法，但根本不起作用，你能帮我找出我的错误吗？

dataGridViewResult.DataSource = morgan.GetResult().Tables[5];
        dataGridViewResult.Rows[0].Cells[1].Style.ForeColor = System.Drawing.Color.Beige;
        dataGridViewResult.Rows[0].DefaultCellStyle.ForeColor = Color.Blue;
        dataGridViewResult.Rows[7].DefaultCellStyle.ForeColor = Color.Blue;
        dataGridViewResult.Rows[40].DefaultCellStyle.ForeColor = Color.Blue;
        dataGridViewResult.Rows[11].DefaultCellStyle.ForeColor = Color.Blue;
        dataGridViewResult.Rows[19].DefaultCellStyle.ForeColor = Color.Blue;
        dataGridViewResult.Rows[28].DefaultCellStyle.ForeColor = Color.Blue;
        dataGridViewResult.Rows[35].DefaultCellStyle.ForeColor = Color.Blue;

        dataGridViewResult.Rows[35].DefaultCellStyle.ForeColor = Color.White;

Answer 1

此代码可能有效：

private void grid1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    DataGridViewRow row = grid1.Rows[e.RowIndex];// get you required index
    // check the cell value under your specific column and then you can toggle your colors
    row.DefaultCellStyle.BackColor = Color.Green;
}

Answer 2

m.lansers回答正确。你有没有把他用的方法绑定到DataGridViews的CellFormatting事件上？如：

dataGridView.CellFormatting += new DataGridViewCellFormattingEventHandler(grid1_CellFormatting);

此外，另一种较短的代码可以使用：

e.CellStyle.BackColor = Color.Blue;
