In stored procedure pass username and password then make select query like

SQL

Select * from table where username=@uname and password=@pwd

for executing the query programatically Check this[^]

Solution 2

Just pass parameter as your user name and password to your store procedure..

and make store procedure like this...

SQL

select * from "tablename" where username = @usernam and password = @password

if this query return something or return any row then your user will valid else not valid...

call that procedure using your code and pass your text boxes value respectively and see the result of your procedure for validation

Da.SelectCommand = new SqlCommand();
Da.SelectCommand.Connection = SqlCon;
Da.SelectCommand.CommandType = CommandType.StoredProcedure;
Da.SelectCommand.CommandText = "YOUSPNAME";
Da.SelectCommand.Parameters.AddWithValue("@UserName", UserName);
