DataGridView.Row[i].DefaultCellStyle.BackColor

Answer 3

参考
DataGridView指定单元格颜色设定
光标下的单元格颜色自动变换  
 [C#]
private void DataGridView1_CellMouseEnter(object sender,
    DataGridViewCellEventArgs e)
{
    if (e.ColumnIndex >= 0 && e.RowIndex >= 0)
    {
        DataGridView dgv = (DataGridView)sender;
              dgv[e.ColumnIndex, e.RowIndex].Style.BackColor = Color.Red;
        dgv[e.ColumnIndex, e.RowIndex].Style.SelectionBackColor = Color.Red;
    }
}private void DataGridView1_CellMouseLeave(object sender,
    DataGridViewCellEventArgs e)
{
     if (e.ColumnIndex >= 0 && e.RowIndex >= 0)
    {
        DataGridView dgv = (DataGridView)sender;
        dgv[e.ColumnIndex, e.RowIndex].Style.BackColor = Color.Empty;
        dgv[e.ColumnIndex, e.RowIndex].Style.SelectionBackColor = Color.Empty;
    }
}

Answer 4

 private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
        {
             if   (e.RowIndex >=   dataGridView1.Rows.Count -1 || e.RowIndex<0) 
                                return; 
                        DataGridViewRow   dgr   =   dataGridView1.Rows[e.RowIndex]; 
                        try 
                        { 
                                if   (dgr.Cells[ "列名"].Value.ToString()   ==   "比较的值") 
                                {
                                    dgr.DefaultCellStyle.BackColor = Color.Gray;
                                } 
                        } 
                        catch   (Exception   ex) 
                        { 
                                MessageBox.Show(ex.Message); 
                        }         }

Answer 6

我把问题在补充一下啊 我从后台数据库中返回DataTable付给dataGridView1。dataGridView1里面每行有个字段Ddate(日期)我想判断日期小于当前时间的就把这行的颜色换为灰色？？？

Answer 7

DataGridView根据单元格值设定单元格样式
单元格负数情况下显示黄色，0的情况下显示红色
 [C#]
private void DataGridView1_CellFormatting(object sender,
    DataGridViewCellFormattingEventArgs e)
{
    DataGridView dgv = (DataGridView)sender;    if (dgv.Columns[e.ColumnIndex].Name == "Column1" && e.Value is int)
    {
        int val = (int)e.Value;
                if (val < 0)
        {
            e.CellStyle.BackColor = Color.Yellow;
        }
        else if (val == 0)
        {
            e.CellStyle.BackColor = Color.Red;
        }
    }
}参考这个吧！对比日期就行了
