类文件中的DataGrid的设置！
我在类文件里定义了一个DataGrid，样式什么的也自己写了一部分，但是当写有DataGrid有事件的时候却不知道如何写？请大家帮忙！
public   static   string   GetDataTable()
{
DataTable   dt   =   new   DataTable();
string   sql   =   "select   *   from   users ";
dt   =   DataAccess.SqlDataAccess.ExeForDataTable(sql);
DataGrid   dg   =   new   DataGrid();
dg.AllowPaging   =   true;
dg.PagerStyle.HorizontalAlign   =   System.Web.UI.WebControls.HorizontalAlign.Right;
dg.PagerStyle.Mode   =   System.Web.UI.WebControls.PagerMode.NumericPages;
dg.PageSize   =   2;
dg.BorderWidth   =   System.Web.UI.WebControls.Unit.Pixel(0);
dg.AlternatingItemStyle.BackColor   =   System.Drawing.Color.DarkRed;
dg.ItemStyle.HorizontalAlign   =   System.Web.UI.WebControls.HorizontalAlign.Center;
dg.Width   =   System.Web.UI.WebControls.Unit.Pixel(400);
dg.HeaderStyle.BackColor   =   Color.Green;
dg.HeaderStyle.HorizontalAlign   =   System.Web.UI.WebControls.HorizontalAlign.Center;
dg.DataSource   =   dt;
dg.DataBind();
System.Text.StringBuilder   strb   =   new   System.Text.StringBuilder();
System.IO.StringWriter   sw   =   new   System.IO.StringWriter(strb);
System.Web.UI.HtmlTextWriter   htw   =   new   HtmlTextWriter(sw);
dg.RenderControl(htw);
string   s   =   strb.ToString();
return   s;
}
