推荐答案

您可以在下面的CellFormatting事件中执行此操作。

You can do this on CellFormatting event like below.

private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    // give the column name which you want to check the value 
    if (this.dataGridView1.Columns[e.ColumnIndex].Name == "ColumnName")
    {
        if (e.Value != null)
        {
            string stringValue = (string)e.Value;
            if (stringValue == "5")
            {
                e.CellStyle.BackColor = Color.Red;
            }

        }
    }
}

尝试 dataGridView1 .Rows [2] .Cells [3] .Style.BackColor = Color.Red
