C# 判断datagridview列值 改变整行颜色我的代码    private void button1_Click(object sender, EventArgs e)        {            DataSet ds = InventoryConvert.order8();            this.dataGridView1.DataSource = ds.Tables["tb"].DefaultView;            for (int i = 0; i < ds.Tables[0].Rows.Count; i++)            {                int dt = Convert.ToInt32(ds.Tables[0].Rows[i][3].ToString());                if (dt < 10)                {                    this.dataGridView1.Rows[i].DefaultCellStyle.BackColor = Color.Red;                }                else                {                    this.dataGridView1.Rows[i].DefaultCellStyle.BackColor = Color.White;                }            }        }

Answer 1

this.dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Red;
this.dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.White;
将i该成e.RowIndex即可

直接 this.DateGirdview.currentRow.backColor = color.red
