Question

I would like to ask your opinions on how the current log in user can view the data that he/her entered. For example, I am building expenses tracking system. Users can insert all the expenses spent by them by select the month ( drop down menu) which I already made and the expenses by insert them in each text boxes. After they’ve confirmed the items, the system will submit all the data in the database (sql).

How can I retrieve only the row that related to the current username to be shown in gridview of something else> I am working with ASP.NET in C# language.

Answer 1

First this is a great tutorial on how SQL and asp.net works together. It explains how to get data from a database and how to update that same data.

http://www.dotnetperls.com/sqlparameter

in the first example the sql statment says

new SqlCommand("SELECT * FROM Dogs1 WHERE Name LIKE @Name", connection))

Your sqlstatment will say

new SqlCommand("SELECT * FROM [What your table name is] WHERE UserID = @UserName", connection))

HttpContext.Current.User.Identity.Name;

on this line replace this

 command.Parameters.Add(new SqlParameter("Name", dogName));

with this
command.Parameters.Add(new SqlParameter(“UserName”, HttpContext.Current.User.Identity.Name));

you will then need to pull your infomation out of your datareader 

Similar to the example above as well. If you need more direction please let me know.

Hope that helps!
