DataGrid列操作

DataTable检测是否存在某个DataColumn 1.if (dt.Columns.Contains("aa") == true){   //存在aa}

2.foreach(DataColumn mDCol in dt.Columns)  {    if(mDCol.ColumnName=="aa") {    //存在aa }  }

怎么样移除DataGrid列private void OnDataBound(object sender, Web.UI.WebControls.DataGridItemEventArgs e){ e.Item.Cells.Remove(e.Item.Cells[0]);}有条件地格式化DataGrid单元格

private void OnDataGridDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e){ if (e.Item.ItemType == ListItemType.Item ||     e.Item.ItemType == ListItemType.AlternatingItem) {  DataRowView rv = (DataRowView)e.Item.DataItem;  // 获取第四列的值  Int32 nUnitsInStock = Convert.ToInt32(rv.Row.ItemArray[4]);  if (nUnitsInStock < 20)  {     e.Item.Cells[4].BackColor = Color.Red;  } }} DataGrid列宽度设置 浏览状态下的列宽度可以这样设置：Column.ItemStyle.Width = 100;

编辑状态下的列宽度可以这样设置：private void DataGrid1_EditCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e){    DataGridItem line = dbgCustomers.Items[e.Item.ItemIndex];    TextBox tb1 = (TextBox)line.Cells[0].Controls[0];    TextBox tb2 = (TextBox)line.Cells[1].Controls[0];

    tb1.Width = Unit.Percentage(100);    tb2.Width = Unit.Percentage(100);    tb2.TextMode = TextBoxMode.MultiLine;}
