I am trying like this:
[code]....
I have a dropdown within gridview i have binded that dropdown with datasource values.
i will select any value from dropdown then it will save in database.
now i want to show the database value in the top value in same dropdown with sqldatasource.
Suppose i have value in dropdown from sqldatasource is test,test1,test2.
Suppose i have selected test1 then it will save in database now i want that dropdown show this values test1,test,test1,test2
What ive been using now is getting datas in code-behind, passing datasource into a Session, re-binds it to a gridview whenever there's paging/sorting needed. What i want to know is what is better if its performance we are talking about?
Is it datasource into a session Or SqlDataSource for which I know whenever paging/sorting needed is that sqldatasource opens up a DB connection to get the datas again?
what i would like to do is when the value of my sqldatasource is returned, then if it is null, run a code, in my case, redirect them to the login page, heres my code:
string connectionString = ConfigurationManager.ConnectionStrings["PokemonPlanetConnectionStrings"].ConnectionString;
string insertSql = "SELECT * FROM LoggedInUsers WHERE UserId = @UserId";
using (SqlConnection myConnection = new SqlConnection(connectionString))
[Code]....
Now what i would simply like to do is, if the select statement searches the database, and the result is not found, the simply redirect them to "register.aspx"
