c#中datagridview处理非绑定列的方法

本文实例讲述了c#中datagridview处理非绑定列的方法。分享给大家供大家参考。具体实现方法如下：

using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.text;
using system.windows.forms;
using datagridview1.dataset1tableadapters;
namespace datagridview1
{
 public partial class form1 : form
 {
  public form1()
  {
   initializecomponent();
  }
  private void form1_load(object sender, eventargs e)
  {
   customerstableadapter adapter = new customerstableadapter();
   bindingsource1.datasource = adapter.getdata();
   datagridview1.autogeneratecolumns = false;
   int newcolindex = datagridview1.columns.add("companyname", "companyname");
   datagridview1.columns[newcolindex].datapropertyname = "companyname";
   newcolindex = datagridview1.columns.add("contactname", "contactname");
   datagridview1.columns[newcolindex].datapropertyname = "contactname";
   newcolindex = datagridview1.columns.add("phone", "phone");
   datagridview1.columns[newcolindex].datapropertyname = "phone";
   newcolindex = datagridview1.columns.add("contact", "contact");
   datagridview1.cellformatting += oncellformatting;
   datagridview1.datasource = bindingsource1;
  }
  private void oncellformatting(object sender, datagridviewcellformattingeventargs e)
  {
   if (e.columnindex == datagridview1.columns["contact"].index)
   {
    e.formattingapplied = true;
    datagridviewrow row = datagridview1.rows[e.rowindex];
    e.value = string.format("{0}:{1}", row.cells["contactname"].value, row.cells["phone"].value);
   }
  }
 }
}

希望本文所述对大家的c#程序设计有所帮助。
