C#中TextBox实现输入提示功能的方法

本文实例讲述了c#中textbox实现输入提示功能的方法。分享给大家供大家参考。具体如下：

设置textbox的autocompletesource的属性为customsource，设置textbox的autocompletemode属性为suggestappend。

using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.text;
using system.windows.forms;
using windowsapplication7.dataset1tableadapters;
namespace windowsapplication7
{
 public partial class form1 : form
 {
  dataset1 ds = new dataset1();
  customerstableadapter adpter = new customerstableadapter();
  public form1()
  {
   initializecomponent();
  }
  private void buildautocompletelist()
  {
   autocompletestringcollection filtervals = new autocompletestringcollection();
   foreach (datarow dr in ds.customers)
   {
    filtervals.add(dr["companyname"].tostring());
   }
   txtcompanyname.autocompletecustomsource = filtervals;
  }
  private void form1_load(object sender, eventargs e)
  {
   adpter.fill(ds.customers);
   buildautocompletelist();
   }
 }
}

希望本文所述对大家的c#程序设计有所帮助。
