Architecture :: How To Make "Watch This Item" On My Page
Nov 29, 2010
I am facing a decision now on how to make a "watch this item" function, like the one on ebay!I was thinking to make a SQL datatable with two fileds, for example: UserID and ItemID, anto store data there,
but I am afraid if I do it like this, my server performance will slow down. For example if I have about 10.000 users and everyone is watching just about 5 items, then my datatable will have about 50.000 entries. I am not really familiar with server performans when dealing with such big datatables. What do you think? Am I going to face problems with server performance
if I do it this way?Second method that I was thinking is to automatically create a datatable for every user in which ItemID will be stored later. With this method I will not have a huge datatable, but then I will have about 10.000 small datatables. Is this a better method?

in asp.net can i make public objects on my page, for example
public Customer cust1 = new customer();
and use this object on my entire code?
what are the drawbacks of creating public objects??
a single object will be created for all users??? or each user will have a different object?

Web based application - Developed in Asp.Net 2.0 and C#The above two uses same database in SQLI do have proper class library/business logic in desktop based application in VB. Now I need to use the same library in ASP.net web based application so that I can change at one place and both the versions will work fine with replacement of one dll.hat is the best to make classes in VB, VB.NET OR C# so that I can use at both end easily.1.

Task is to develop class libraries that can be re-use in projects but assambies should be copy righted. By this I mean developer will not give the code of class libraries to the clients yet they will provide the code of there sites/ applications, these libraries will be used just as internal development libraries. I want to make Business Logic Layer, DAL, Business Objects as class libraries
Q1. How I can control unathorised use of libraries ?
Q2. How to make assamlies non extendable ?
Q3. What security measurs I should take on this.

I'm working on a webforms aspx app (not MVC) and I'm not sure if I should just create separate pages or somehow make multiple views on the same aspx page for the following scenario: Basically, I need to give the user the option to view a set of data a few different ways (essentially different group by's from a data perspective)... the data is always the same, its just a matter of how to arrange on the page...
each way I need to present the data will essentially consist of 2 repeaters, one nested inside the other. The outer repeater will display a nice header section with the nested repeater showing the list of items under that heading. view by book title (title is outer repeater, with the book list being the nested repeater, yes, multiple books with same title for this example - the app has nothing to do with books, this is just to illustrate)
Book Title: A Good Story
Author - Publisher - ISBN
Dan Johnson - Smith Publishing - kjdkjfd99898989
Susan Day - Smith Publishing - aa777fd99ff

Or, view books by publisher (here the publisher would be the outer repeater and the list, with different fields compared to first view, is the nested repeater.

so what do I do here? Just making separate pages is simple and would work, but is there something else I should be considering? There will be 3 different views, so 3 pages total if I went that route. Something is making me think I should be doing this all within one aspx page? maybe just toggling the visible property of the repeater controls? but then I was thinking each of these repeater controls is databound, and I assume even if they are not visible they still incurred database hits to get the data, right? and that could be bad?

I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.
The InsertItem Template is in the first position, making it easy to insert a new record.
And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.
I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
which works fine also.
The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:
Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub
This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.
Here is the code for a typical entry of the InsertItem Template:
[code]....
All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"
How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?
