Dategridview的用法.doc

Dategridview的用法1. 填充dategridview的数据Dategridview1.datesource=ds.tables0.defaultview;2. 将dategridview中的数据填充到textBox中Int index=this.Dategridview.currentCell.rowIndex;If( index!= -1) textBox1.text=this.dategridView1.Rowsindex.Cells0.value.tostring();3. 选中dategridview的一行数据（用到cellmousedown事件） private void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e) if (e.Button = MouseButtons.Right & e.RowIndex -1 & e.ColumnIndex -1) dataGridView1.CurrentRow.Selected = false; dataGridView1.Rowse.RowIndex.Selected = true; dataGridView1.CurrentCell = dataGridView1.Rowse.RowIndex.Cellse.ColumnIndex; 4datagridview 上一条数据，下一条数据实现private void button2_Click(object sender, EventArgs e) if (dataGridView1.CurrentCell.RowIndex !=0) dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect; this.dataGridView1.CurrentCell = this.dataGridView1this.dataGridView1.CurrentCell.ColumnIndex, this.dataGridView1.CurrentCell.RowIndex - 1; textBox1.Text = dataGridView1.RowsdataGridView1.CurrentCell.RowIndex.Cells0.Value.ToString(); else MessageBox.Show(第一条数据); private void button3_Click(object sender, EventArgs e) if (dataGridView1.CurrentCell.RowIndex != dataGridView1.RowCount - 1) dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect; this.dataGridView1.CurrentCell = this.dataGridView1this.dataGridView1.CurrentCell.ColumnIndex, this.dataGridView1.CurrentCell.RowIndex + 1; textBox1.Text = dataGridView1.RowsdataGridView1.CurrentCell.RowIndex.Cells0.Value.ToString(); else MessageBox.Show(最后一条记录); 5dategridview绘制跨越整行的文本内容使dategridview中文本显示绿色 private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e) DataGridViewRow dgr = dataGridView1.Rowse.RowIndex; dgr.DefaultCellStyle.ForeColor = Color.Green; 6 DataGridView 取得或者修改当前单元格的内容： 当前单元格指的是 DataGridView 焦点所在的单元格，它可以通过 DataGridView 对象的 CurrentCell 属性取得。如果当前单元格不存在的时候，返回Nothing(C#是null) / 取得当前单元格内容 Console.WriteLine(DataGridView1.CurrentCell.Value) ; / 取得当前单元格的列 Index Console.WriteLine(DataGridView1.CurrentCell.Column Index); / 取得当前单元格的行 Index Console.WriteLine(DataGridView1.CurrentCell.RowInd ex);） 行、列的隐藏 C# / DataGridView1的第一列隐藏 DataGridView1.Columns0.Visible = false; / DataGridView1的第一行隐藏 DataGridView1.Rows0.Visible = false; 2） 行头、列头的隐藏 C# / 列头隐藏 DataGridView1.ColumnHeadersVisible = false; / 行头隐藏 DataGridView1.RowHeadersVisible = false;/当前单元格是否选择的判断 if (DataGridView1.CurrentCell = null) return; int insertRowIndex = DataGridView1.CurrentCell.RowIndex;C#追加文件 StreamWriter sw = File.AppendText(Server.MapPath(.)+myText.txt); sw.WriteLine(追逐理想); sw.WriteLine(kzlll); sw.WriteLine(.NET笔记); sw.Flush(); sw.Close();C#拷贝文件 string OrignFile,NewFile; OrignFile = Server.MapPath(.)+myText.txt; NewFile = Server.MapPath(.)+myTextCopy.txt; File.Copy(OrignFile,NewFile,true);C#删除文件 string delFile = Server.MapPath(.)+myTextCopy.txt; File.Delete(delFile
