Dear Friends, a very good morning to everyone.

am working on Asp.net,C#,SqlServer 2005.

My Requirement is I have a Textbox to Search the data from Gridview...its working fine.

now I need to add space in Textbox after entering 2 letters in Textbox.

for example I need to Search like this.....

MS 651
AT 258
XY 701
IY 532

I need a single Space after two characters like this MS 651...so that I can Search the data easily.

for displaying capital letters i gave textbox css as
text-transform:uppercase;
its working fine.

But I need a single space after two characters entered in TEXTBOX.

Please help me,

THANKS.

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).
