Caching Question

Posted By:      Posted Date: October 06, 2010    Points: 0   Category :ASP.Net

I wanted to know the best practice for caching data.

Say I have some control example a dropdown list which is populated from my db. Now this dropdown is global and used across many pages.  I was thinking of not going to database everytime to fetch data for this dropdown and put the result in Cache. And then populate this dropdown from cache. 

Is this a good practice or if there is another approach. Can I store my datareader in cache and then use it globally. Also could I do this in application start event?

ASP.Net Caching problem ??


I'm having a problem with an asp.net 3.0 application using a gridview to display data.  The problem seems to be that despite a brand new .selectCommand being sent to the sqlDataSource, the gridview starts displaying data from *someone else's* query.  For example, user A is logged in and will be working fine until a few page submissions later when the gridview data starts suddenly showing information that belongs to another user. 

This is my first asp.net application, though I've been working with classic asp and ADO for years so I'm used to sending a SQL string and getting back the results from that string.  Apparently there is a complex caching system which is interferring which I do not at all understand so at this point I just want to stop the server from caching any data whatsoever.  Is this possible?

Any and all help will be much appreciated!!

is the page caching?


I am just trying to understand the basics flow to the MVC framework by putting in some breakpoints in the beginning of the actions of a couple of controllers.

One break point is at the HomeController/Index action where it just returns View() of the "Welcome to MVC".  The Second break point is at a SecondController/Index action where it uses the Entity Framework and returns a View() of a list from the db.

When I run this in debug, it breaks at the points I expected when I go from Home page to the Second page controller and back to Home.  However, when I go to the Second page again, it doesn't break at all?  Is the results of the Second page being cached and how and where?  How do you trigger for it to get check if data is old?

I check to see if the persistence is done on the db, by changing the value of a field on the db side and it still did not cause it to break on that action and displays old information in the view.  I am concerned because it is displaying incorrect values on the UI.  I do not have the OutputCache attribute above this action or specified any cache on my web.config.

Thanks in advance for your time :)

Some basic MVC question

  1. In regular asp net I can run (debug) the application but I can either "view in browser" that gives me the option to view the application and write code on same time.

In MVC I can't find this option.

  1. What is the basic DATA MODEL for working with SQL DB.

I mean with no any framework (entity framework, Sub sonic, Link to SQL etc')

I look for basic application that works with data but with no fw.

  1. What is the popular DB framework that working with data.
  2.  I am looking on  mvc series

Web Site to Web Application Question


I've been building web sites and for my next project I will be creating a web application.  I use a 'BasePage' class in all my projects but, since web applications do not contain the 'App_Code' folder, what is the best place/practice for the 'BasePage' class?



connection string question from a newbie


when publishing  in the webmatrix dialogue it asks for "destination connection string" for my "database.mdf"

I was not sure what it was so I pasted this from my web.config file :

Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\database.mdf;Integrated Security=True;User Instance=True

it all published ok, but wont run, so I guess it has somthing to do with this connection string or some kind of configuration issue.

My question is this, What should go in the field for "Destination connection string"

Security Question Answer Retrieval


I know there is a method built in for retrieving the encrypted password, but how do I retrieve the encrypted security answer?

What I want to do is have a member profile update screen that the end user can update their password and security question and answer. However, when they get to this page, I want to already be showing the security question (the easy part) and its answer (the not so easy part).

I have updated web.config with passwordFormat=Encrypted and have added a machineKey with the generator (forgot the link, but located on eggheadcafe somewhere).

I haven't done ANYTHING yet, since I already have a user store with hashed information. I wanted to get some functionality done before publishing, wiping the store and recreating users (only a couple developers).


Data caching c#.net


Hi Friends,


I have a large SQL Database in the server from which I can create a dataset of about 10000 rows. My question is about caching this data. Which type of data caching should I choose (Server side or Client side)? Which one will provide better performance?


Thanks in advance

Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!




C#, LINQ: (List<>) Question???


Hi Everyone,

I have a strange problem:


There is an entity (Table) called "Filters" in my .edmx which has all my tables and stuff in it (to use it for LINQ queries)

I have created a class called "CustomFilters" which inherits "Filters". So now my cutom class has all the properties of the original "Filters" class (table) and 1 more additional property that i wanted which is a List of "CustomFilters":

List<CustomFilters> children = new List<CustomFilters>();

Now i get all my records into:

List<CustomFilters> theOriginalList = new List<CustomFilters>();

NOTE: first all records are tken into a List<Filters> and then these are added into List<CustomFilters> where List<CustomFilters> for children of that record is added, and then children of the child records, and so on......

so now, every record is an instance of CustomFilters which has a property named "children" which is a list again; and each child again has instanaces of "CustomFilters", and each instance again has children...and on and on and on.....

(basiacally its a data source for a treeview in my silverlight control)

every thing is good and working as expected.


linqdatasource parameters question



I'm currently getting to know the linqdatasource control. What would happen if several WHERE parameters are added to the linqdatasource control declaritively in the aspx page but no WHERE clause is defined? 

1. is there any issue with setting up multiple WHERE parameters in the aspx markup for linqdatasource but then deciding which ones actually get used at runtime by setting the actual WHERE clause at run time? Would the unused parameters simply be ignored and cause no issues?

2. when you need to modify WHERE clause or WHERE parameters at runtime do you need to do so in an event handler? such as linqdatasource.selecting?
I see from the above link it is possible, but is that the standard way to handle controlling filtering in code behind for linqdatasource?

2b. if you use an event such as linqdatasource.selecting to add where parameters and/or modify the where clause in code will that also break the builtin sorting and paging support of the linqdatasource with a gridview?
