输入2个字符后，文本框中需要一个空格. [英] Need a Single Space in Textbox after entering 2 characters.

问题描述

亲爱的朋友们，大家早上好.

正在使用Asp.net，C#，SqlServer2005.

我的要求是我有一个文本框可以从Gridview中搜索数据...工作正常.

现在我需要在文本框中输入2个字母后在文本框中添加空间.

例如，我需要像这样进行搜索.....

MS 651
在258
XY 701
IY 532

我需要像MS 651这样的两个字符后面有一个空格...以便我可以轻松地搜索数据.

用于显示大写字母，我给文本框css为
text-transform:uppercase;
工作正常.

但是我在TEXTBOX中输入两个字符后需要一个空格.

请帮帮我，

谢谢.

for displaying capital letters i gave textbox css as

推荐答案

使用字段验证器并编写正则表达式(regex)来解决您的问题.
这是.net的正则表达式类的链接
http://msdn.microsoft.com/en-us/library/system. text.regularexpressions.regex.aspx [ ^ ]

和你的孩子会是这样的

字符串模式= @"[[A-Za-z] [A-Za-z] \ s [0-9] {6}";

[] =此集合中出现了一次
\ s =空白
{X} =总长度为X(如果空格后的数字可以变化，请不要使用该数字).

use a field validator and write a regular expression (regex) to solve your problem.
here is link for regex class of .net
http://msdn.microsoft.com/en-us/library/system.text.regularexpressions.regex.aspx[^]

and your patren would be something like this

string pattern = @"[A-Za-z][A-Za-z]\s[0-9]{6}";

[]=single occurrence from this set
\s= white space
{X}=total length is X (dont use this if the digits after space can vary).
