dataGridView如何根据某一列值不同颜色

1、在DataGridView的RowDataBound事件里判断并修改：if(e.Row.Cells[n].Text=="0"){e.Row.Attributes.Add("bgColor", "red");}else if(e.Row.Cells[n].Text>"500"){e.Row.Attributes.Add("bgColor", "green");}

2、在winform里，DataGridView没有RowDataBound事件，如果在winform里，如下修改：private void dataGridView1_RowPre霸烹钟爷Paint(object sender, DataGridViewRowPrePaintEventArgs e){if (e.RowIndex >= dataGridView1.Rows.Count - 1)return;DataGridViewRow dgr = dataGridView1.Rows[e.RowIndex];

3、try{if (dgr.Cells["列名"].Value.ToString() == "比较值"){dgr.DefaultCellStyle.ForeColor = 设置的颜色;}}catch (Exception ex){MessageBox.Show(ex.Message);

4、}}ItemDataBound事件里if (e.Item.Cells[性别列的索引值].Text == "男 ")e.Item.BackColor = System.Drawing.Color.Red;if (e.Item.Cells[性别列的索引值].Text == "女 ")e.Item.BackColor = System.Drawing.Color.Blue;

5、private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e){if (e.Value== "男 "){e.PaintBackground(e.CellBounds, true);}}

6、注意：在winform里，DataGridView没有RowDataBound事件，如果在winform里，如下修改： 调吹涡皋陕用DataGridView中的RowPrePaint事件private void dataGridView1_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e){if (e.RowIndex >= dataGridView1.Rows.Count - 1)return;DataGridViewRow dgr = dataGridView1.Rows[e.RowIndex];try{if (dgr.Cells["列名"].Value.ToString() == "比较值"){dgr.DefaultCellStyle.ForeColor = 设置的颜色; (如：Color.red)}}catch (Exception ex){MessageBox.Show(ex.Message);}
