ComBox很简单的一个问题,急....在线等..

[wangping_li]

我在我的ComBox里面有如下选项..现在要实现一个功能就是输入汉字首字母出来符合条件的汉字，比如:css就出来包含＂测试商＂文字的所有值.望各位大虾帮帮忙．小弟先谢了.
测试商品八
测试商品二
测试商品九
测试商品六
测试商品七
测试商品三
测试商品十
测试商品四
测试商品五
测试商品一

[wangping_li]

我们个东西不能在Button事件里面写啊,应该到TextChanged事件里面．但是那样就报错．重新绑定也有点问题．

[sy1987611]

放在TextChanged里面是一样的阿，你的文本框的名字不会跟ComBox的名字一样吧
if (str[i].Substring(0, 文本框的id.Text.Length).IndexOf("文本框的id".Text) > -1)
{
MessageBox.Show(str[i]);
}

[jinjazz]

没个中文都应该事先对应好自己的拼音简写，然后用ajax去动态匹配

[wangping_li]

我用winform实现.　能否给点源码.谢谢.asp.net也行
比如：测试商品一(对应的汉字首母是csspy)和测试商品二(csspe)
当我输入cssp或者就一个c的时候怎么让两个都显示出来?谢谢

使用ASP.NET AJAX Control Toolkit中的ListSearchExtender

参考：

//得到单个字符的首字母 
private String GetOneIndex(String OneIndexTxt) 
{ 
if(Convert.ToChar(OneIndexTxt)>=0 && Convert.ToChar(OneIndexTxt)<256) 
return OneIndexTxt; 
else 
{ 
Encoding gb2312 = Encoding.GetEncoding("gb2312"); 
byte[] unicodeBytes = Encoding.Unicode.GetBytes(OneIndexTxt); 
byte[] gb2312Bytes = Encoding.Convert(Encoding.Unicode, gb2312, unicodeBytes); 
return GetX(Convert.ToInt32( 
String.Format("{0:D2}",Convert.ToInt16(gb2312Bytes[0])-160) 
+ String.Format("{0:D2}",Convert.ToInt16(gb2312Bytes[1])-160) 
)); 
} 

} 


//根据区位得到首字母

ComBox实现？
数据库表得设计好，
拼音用几列，或只用1列加分隔符的字符串
根据输入内容查询数据库拼音列，
再重新把ComBox绑定数据~

[wangping_li]

NekChan 你这个方法转换以后是不是我在textChanged事件里面调用？

[wangping_li]

我这个是静态的,不用数据库的．只是模似一下

txtID1.text是自己输入的吗?

是的

好像有点不对..输出结果什么也没有
以下是我的代码:

大虾们可不可以帮帮忙

[wangping_li]

addItems是绑定ComBox列表的,就是从这个Items里面去检索

[wangping_li]

TO:sy1987611
你上面的方法可以找到符合我输入条件的字母，比如我输入css就可以找到全部，现在让找到的这些值在下拉例表的呈现出来啊，怎么绑定ComBox?

[sy1987611]

要么就动态生成一个ComBox,要么就把以前的ComBox里面的值删除，把匹配的this.CB_OrderName.Items[i].ToString()重新绑定。
