I searched for this problem.Solutions is Use HiddenField for getting server side.

View 2 RepliesI have a File Uploader in my ASP.NET application Using C#, we can upload any type like images, documents, pdf etc.
I m storing it in the Filesystem and having only the Name of the File in DB.My doubt is can we store the entire file, images in DB. State me Which is good practice and why we need to use it.
Either file System Storage or SQL DB Storage.
I am having a page where I need to maintain around 70 to 80 hidden fields to store some values. These are required because I need these values for executing some code at the client side (validations, calculations, etc,.) in java script.
Wanted to know if there is a better way of storing these values in my page instead of using hidden controls because I guess using so many hidden controls is making my page very heavy.
Something like a hash table or list dictionay that I can access from both the server side code and clint side java script?
I have 2 listboxes,if i select listbox1 items ,it has to be displayed in listbox2 without duplicate values.
for example if i select item "usa" in listbox1 it has to be added in listbox2.
Aagain if i select " usa" it should not add to listbox2.
one more point is i dont want to delete items from listbox1 once i select.
i want to know how to copy multiple items from Listbox1 to Listbox2.i tried in single item copy it's working but i want to know multiple items to copy.
here is my code..

I'm trying to store multiple selected checkboxes from a single checkboxlist, but i don't know where to start. Imagine i have three tables: tbl_events, tbl_organisors and tbl_settings and i want to store the organisors of an event. Each event can have multiple organisors, so each organisor should be added as a single row into tbl_settings. I know how to bind tbl_organisors to a checkboxlist, but how do i store the results (meaning: add the rows to tbl_settings) ?
tbl_events: Event_ID (PK) and Event_Name
tbl_organisors: User_ID and user_name.
tbl_settings: Settings_ID (PK), Event_ID and User_ID
Checkboxlist:
[Code]....
SQLDatasource:
[Code]....
Initially all checkboxes will be unchecked, but users must be able to select multiple organisors from the checkboxlist and then store them into the DB by submitting a form. So the query will look something like: INSERT INTO tbl_settings (user_id, event_id) VALUES (@user_id, @event_id). And this is where my head cracks
1) How do i loop through all selected checkboxes and store each value (user_id) in a new row in tbl_settings?
2) After saving, the users reloads the page and the organisors he just selected must be selected by default in the checkboxlist. How?
I've got a table where i'm storing a CheckBox.Checked value.
I'm using C# and the value of the field in the table im writing to is a bit.
myDS.InsertParameters["p1"].DefaultValue = CheckBox1.Checked.ToString();
The value placed in my table ends up being either "True" or "False".
So when I try to query the table based on that value with a stored procedure it doesn't work since its looking for a 1 or a 0.
I think the .ToString() is part of the problem but i don't know the syntax to have the value from the CheckBox.Checked to be written as 1s or 0s instead of true or false.
One my web application uses barcodes.... When i add a new item i am generating a barcode value which is converted to a barcode image... My question
What would you suggest storing barcode values or barcode images in sql server 2005?
EDIT:
What Type of barcode you would suggest using with an asp.net application?
Linear Barcode (Code 128) is my choice..

View 1 RepliesI have 2 listboxes....
Listbox1 has
DataTextField="Category"
DataValueField="CategoryID"
(coming from Dropdownlist)
I want to move a Item (a Category) from listbox1 to listbox2...but how do I move this Category Plus the CategoryID to lisbox2 (CategoryID should not be visible but still be associated with Category in Listbox2)
So I want the newly added Categories to be visible in Listbox2 ..but their CategoryID's must be invisible...but still be associated with their Category....
and when I save these Categories from Listbox2 to the Database.....its should be the CategoryID's that should go into the Database.....not the actual Category
So to explain again in a different way
I want to Move a selected DataTextField & its DataValueField from Listbox1 to listbox2
then only the array of DataValueField must be saved to Database
currently in our application we have an ApplicationConfiguration class. It is basically just a static class with const values specifying certain application-global configuration options. Some of these values will rarely if ever change and are only put into the configuration for elegance/cleanness.
Some of these values though do need to be different between production and development. So I'm considering making this class just a wrapper over Web.config. These values are checked many times throughout our codebase. If I change these from a const to a read-only getter that reads from Web.config will this affect compiler optimizations or make our application in any way slower?
Well basically I can't find anything regarding storing an image within a folder on the server, as appose to the SQL database. I have already written code to store the image within my database, but I also need to store the image as a physical entity for CSS purposes, here's a part of my code which can probably be used.

I can upload the file using my MVC application without any errors, however in the database the file stores in CoverFileContent as "0x0000000000000000......". All the other information relating to the file, e.g. MimeType, FileName, CoverID, etc uploads correctly. I took a wild guess that this wasn't correct so I downloaded the file (created a .net MVC file downloader). It seemed to download as the correct type of file, however I when I tried to open it, it told me I could not open it. I'll post some snippets of my code so people can see what I'm doing.

I have inserted breakpoints to debug the code, however coming from more of a business background I'm not sure what I'm supposed to be looking for. It seems that the array is being populated with 00000000s so I'm thinking this is a problem regarding the intake of the file.

I would like to know which is better? Storing images in BLOB or in the File System ? I've got around 400 to 5000 images.
And at run time there are chances where I'll need to retirieve about 100 - 150 images.
