Extracting data from Table2 to TextArea of Table1 - asp.net

Question

I have designed 2 tables in my aspx page. In table1 there is blank TextArea. In table2 there are fields like FirstName,LastName,Age,DOB and these attributes are already entered in the database. I have entered corresponding symbols for these attributes (for e.g. for Firstname symbol is {F}, for last name symbol is {L} etc..).
My requirement is when i click on a field of Table2 (for e.g. FirstName) it will be displayed on TextArea of table1 like "Hi My Name is {F}".

Answer 1

I have tried myself to do this program, but i did not extract the
symbol of the attribute in my textarea.
