Web Forms :: Exactly Does The Text='' Represent?
Apr 19, 2010
I'm using a text box in a template field to perform an insert with an object data source. What exactly does the "ProductID" refer to in this example? Is it the column in the db or the business object?
[Code]...

If I have a text file like:
123, joe blow, USA
Where the first values represent:
USERID, NAME, COUNTRY
If my file has 5000 rows, could I update a particular row somehow using C#?

Just for an example, if I have three controls on a Master page, I would usually declare a variable for a control like this.
var elem = document.getElemntId('<%=control1.ClientID %>');
var elem2 = document.getElemntId('<%=control2.ClientID %>');
var elem3 = document.getElemntId('<%=control3.ClientID %>');
Can I do it in some form of concenation like:

I would like to add a checkbox to my grid view to represent a bool property of the list the grid view is bound to.
I want to show a checked checkbox for true instead of just showing text of 'true' or 'false'
Is this possible. When I try to add the checkboxfield in the gridview wizard. The add button is grayed out when selecting checkboxfield

I'm a novice developer writing an ASP.NET application with VB. I'm having a little trouble getting my head around the partial class concept. If you use the partial classes as a code-behind for the presentation, how would these be represented in UML, in particular with a class diagram?

how to create C# classes to represent one to many relationships in C#. I have a Customer and an Address table in my database. I also have a Customer class in my C# solution but how do I introduce the multiple address element? Do I have a separate Address class? Do I create a subclass in the Customer class or create a method in Customer called GetAddresses of type List which contains all of the relevant logic? In my code I need to be able to return a customer with all associated addresses and I just cannot picture the best way to achieve this using OOP.

i'm new with design patterns and i'm not sure if in this situation i can use a composite pattern.
The scenario is a web application for an address book : the address book cointains AddressBoookItem, generalization for Contact and ContactGroup. The last one is the composite object containing a collection of AddressBoookItem.
With these scenario i'm sure that this is a composite pattern, but what is confusing me is that a contact may belong to many contactgroup. Does this request change the situation? Till now i thought that between the Leaf object and the Composite (in the composite pattern) there was a 1-to-m relationship (a composite may contains many leaf but a leaf is contained in only one composite object). Can i still use the composite pattern ? And, the last question,
How could i represent my scenario in a relational database? One table for the entire hierarchy or two table (Contact and ContactGroup) with a m:n relationship between them ?

I need to design a system that will control access to certain information. The requirement from the user is to use access levels e.g.
Level 1 - Support
Level 2 - Manager
Level 3 - Senior Manager
Level 4 - Department Head
etc.
If a certain piece of information is marked as Level 1, then all roles should be able to view that piece of information. If it is marked as level 3, then only the Senior Manager and Department Head can view it, but the Manager and Support roles can't view it.
Questions
When I assign the access level to a piece of information, will I have to assign multiple roles to it in order for me to achieve this functionality? Is there a better way of doing this?

Currently I have a class that represents a document. This document needs to be displayed as HTML. I would like to have a method to call such as GetHTML() that would then call GetHTML() on any properties/sections of the document that needed to be rendered. I was initially thinking about using linq and XElement but am wondering if that may cause issues with certain tags in HTML. Would I better off using an HtmlTextWriter?

This is probably something that you may have encountered in the past and I hope not to re-invent the wheel.I need to display on a web for the choice of actually entering a date using a calendar or the person can enter until "Present" for e.g. Most people have in their resume's the start date and end date of their last project. The current project does not have an end date, people generally put in from Mar-2009 to Present. I need to be able to provide this functionality to the users.Anyone encountered this problem before? Any ideas on how the UI can look like?

This is in my opinion an abstract problem and I hope I can explain it well. I happened to find the same kind of problem in a completely different project and now I have it again and I would like to avoid it if possible.
I'm creating some classes to simplify some tasks for some specific requirements we have in some projects at work.
I have a class that creates objects which maps the values from webcontrols to an object properties similar to this
[URL]
The problem I have it's sometimes I have to store a non container object in a place (in an object's attribute) and sometimes I have to a store a container object in the same place for storing the values of a webcontrol (a webcontrol can sometimes hold several values like a checkboxlist). I dont like this at all, because some time ago when working in a non commercial compiler, when parsing and generating the intermediate code I had sometimes to store a container in a place, and sometimes I had to store a non container in the same place, and having to ask in other parts of the code if what you are reading is this type of object, or this another type of object, it is something really annoying and it mess up the code. Is there any tips about what it would be better to do to avoid this kind of situations or nothing can be done to avoid it sometimes?

There are multiple roles. (Role A, Role B etc) There are multiple input/output fields. (Field A, Field B etc) There are multiple permission levels controlling access to each field. (Read, Direct Edit, Edit With Approval, None) Each role has its own permissions to fields. (Role A has Read Permission to Field A; Role B has Direct Edit permission to Field A etc) Every role can be assigned to users and they are assigned by Geographic information. (User A is assigned to Role A for Continent: Europe - Country: Germany; User B is assigned to Role A for Continent: Europe - Country: France; User A is assigned to Role B for Continent: Europe - Country: France etc) Users can have multiple roles User identity is coming from Windows Authentication.
is it possible to represent this type of kind of multi-layered security model using ASP.NET internal membership/role providers? If so, what should my starting point be? Creating only custom role provider with custom methods and fields be enough?

Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions.Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types?-or-Is there a way to pull out the raw text from the SQL Full text index, without using 3rd party filters?Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene

I have a page with a text box, a button and a GridView. Enter an account number in the text box, press the check button and the result will show in the GridView.
Now user wants that if the text box is clear, the GridView disappear.
I can only find TextBox1_OnTextChanged. But I want to have that while the user is clearing the text, if the length of text becomes zero, the GridView is clear out. So I am looking for OnTextChanging(). Well of course this function does not exist. How to achieve the same purpose?
