c＃.net中的动态自动完成文本框 [英] Dynamic auto complete text box in c#.net

问题描述

.net中的自动完成文本框属性在编码阶段提供了自定义源，但它必须在运行时在源中保存新的。我找到代码但新的代码保存到应用程序打开之前。然后我们关闭并再次打开它不会显示新的。

推荐答案

属性你必须设置到文本框：



AutoCompleteMode：建议追加

AuoCompleteSource：CustomSource



这些属性必须设置为文本框，为这你要设置AutoCompleteMode的文本框。

然后只会执行代码。





事件：此代码应在Page_Load中编写事件





的SqlCommand CMD =新的SqlCommand（ 从databasetable选择姓名，CON）; <无线电通信/>
SqlDataReader dr = cmd.ExecuteReader（）;

AutoCompleteStringCollection col = new Aut oCompleteStringCollection（）;

while（dr.Read（））

{

col.Add（dr.GetString（0））; < br $>
}



textBox1.AutoCompleteCustomSource = col;



我希望这段代码将帮助您。

Properties those you have to set to the textbox :

AutoCompleteMode : Suggest Append
AuoCompleteSource : CustomSource

These properties must set to the textbox that to which textbox you want to set the AutoCompleteMode.
Then only the code will be performs.


Event: This code should write in Page_Load event.


SqlCommand cmd = new SqlCommand("select name from databasetable", con);
SqlDataReader dr = cmd.ExecuteReader();
AutoCompleteStringCollection col = new AutoCompleteStringCollection();
while (dr.Read())
{
col.Add(dr.GetString(0));
}

textBox1.AutoCompleteCustomSource = col;

I hope this code will help you.
