Solution 1

SQL

qry = "select full_name from Players";

Please pass the Dropdownlist selectedvalue to the query as where clause . Then particular result set olny fetch.

You need to modify the query for that. You have not included the WHERE clause in the query. The query would look like

SQL

SELECT full_name FROM Players WHERE id = @id

and you need to add a SqlParameter to your code like

C#

cmd.Parameters.Add(new SqlParameter("@id", DropDownList1.SelectedValue));

Of course, the parameters in the where query could vary depending upon the table structure in your case.

If you can provide it, I can help you further.
