I am using ASP.Net with VB.Net Visual Studion 2010
I have a textbox if I write i.e. 654321-1 and immediately it verify from database table that this is already exists in database or not.
Suppose on Gmail if we create new email address it immediately verifies from database and says "This ID has already taken" and gmail gives suggestion to add some numeric or character with it.... i.e. if i write asif14443 and this is already in database and gmail will give suggestion asif14443pk , asif144432014 etc.etc.
But in my case I have to just check duplicate from database. If possible please email me the solution to my email address <<snip>>
