dataGridView如何根据某一列值不同颜色
方法/步骤
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");}elseif(e.Row.Cells[n].Text>"500"){e.Row.Attributes.Add("bgColor","green");}
2、在winform里，DataGridView没有RowDataBound事件，如果螅岔出礤在winform里，如下修改：privatevoiddataGridView1_RowPre霸烹钟爷Paint(objectsender,DataGridViewRowPrePaintEventArgse){if(e.RowIndex>=dataGridView1.Rows.Count-1)return;DataGridViewRowdgr=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(Exceptionex){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、privatevoiddataGridView1_CellPainting(objectsender,DataGridViewCellPaintingEventArgse){if(e.Value=="男"){e.PaintBackground(e.CellBounds,true);}}
6、注意：在winform里，DataGridView没有RowDataBound事件水貔藻疽，如果在winform里，如下修改：调吹涡皋陕用DataGridView中的RowPrePaint事件privatevoiddataGridView1_RowPrePaint(objectsender,DataGridViewRowPrePaintEventArgse){if(e.RowIndex>=dataGridView1.Rows.Count-1)return;DataGridViewRowdgr=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(Exceptionex){MessageBox.Show(ex.Message);}
