Write a select query to check if textbox value is there in DB.If the number of record returned is greater than 0,then textbox value already exist

Query will be something similar to:-

SELECT count(*) from your_table where field = textbox.value

Read more about count http://msdn.microsoft.com/en-us/library/ms175997.aspx
So if it returns more than 0,that means record exist in DB with the value of textvalue
