Forms Data Controls :: How To Display Category Name Without Category Id
Mar 30, 2011I am working in a project that is a musical website. I want to display the web page with all categories I have. In my database , named Category_Master, I have two fields like Category_Id (which is a primary key ) and Category_Name. I have generated category_Id with NEWID() function. The category_Id is not supposed to display on the web page. But, i have to select Category_Name and according to that , I have to get the category_Id. If I am using Static connection with SqlDataSource, i am able to make visible=false property so that the category_id won't be visible. But , at that time, I can't write code to Select the category_id of the selected index.
If i am using disconnected approach, I filled the dataset with the Category_Master, and binded it to GridView. But, at that time, I can't hide the category_id from the user. I want to select category_id by clicking on the category_name with out displaying category_id ..?

Get An Error A String (selected Category In The Ddl) Cannot Be Converted To A Category Object?
Feb 7, 2010I'll try to explain as simple as I can in text what my problem is. I don't see any other way to make my issue clear.
I have a GridView that uses an ObjectDataSource.
The ObjectDataSource has an DataObjectTypeName defined, so I pass/get complete objects or list of objects to/from the data access methods.
The objects I'm working with, let's say we work with Book objects, contain a Title and a Category, BUT the Category is an object itself. When the Select method is called, we get a List of Book objects, which is perfectly displayed, overridden ToString method in the Category objects within the Book objects.
The problem I face is that I can't find a way to update the category in my GridView. What I did already accomplish is:I used a template field in the GridView for the Category so I could use a DropDownList for that field in Edit mode.
I bound the DropDownList to another ObjectDataSource that gives me a list of CategoryObjects.
So when I enter Edit mode... the row shows a nice ddl with the available categories. It even selects the right original category.
So far so good... but when I want to save my new selection, I get an error that a string (the selected category in the ddl) cannot be converted to a Category object (that's what the Book object, that is going to be used for the update, expects).

Active Directory/LDAP :: Nested Groups Filter/create A Filter Which Will Return All The Users Which Belong To One Of The "kuku"s Group?
Mar 9, 2010In my organization we use nested groups. For a particular usage, we have a group (let's assume that the group name "kuku"), and the names of all the nested groups under it contains "kuku" as well.
We may assume that no other group in the LDAP has "kuku" in the name.
I need to create a filter which will return all the users which belong to one of the "kuku"s group.
Obviously, using this filter will bring only the head kukus
(&(&(objectclass=user)(objectclass=person))(memberOf=CN=kuku,cn=...rest of the group DN...))
How can I use wild card to fetch all users which belong to any kuku?
For example: (&(&(objectclass=user)(objectclass=person))(memberOf=CN=.*kuku.*))
C# - Run Both Authorize Filter And Action Filter On Unauthenticated MVC Request
Mar 17, 2010I have decorated my base controller with a couple of action filters. They work fine.
One of those filters sets up the request - does things like set the culture based on the domain, etc.
I also have a handful of actions that require authorization using the Authorize attribute.
My problem is that when an user attempts to request a page they are not authorized to access, the authorization filter kicks in and redirects them to a page telling them that they cannot vie the page.
The issue is that the action filters never run so the culture and other request data is never set. This effectively causes language to be wrong in the view and other data to be missing.
I know that authorization filters run first but my question is this: How can I design this such that I can ensure that certain methods are always run before the view is returned, regardless of the authorization.

Forms Data Controls :: Add A Sub Category To A Gridview?
Apr 26, 2010I'm working on a dynamic table of contents (toc). The toc is generated from data in a sql database. There are 5 sections in the toc and within each of the five sections, there are a varied number of rows. (Section 1 may have 5 rows, while Section 2 has 12 rows). To help differentiate between the sections, I'd like the ability to add some type of grouping in my gridview. So, it would look like below. Do I just add a different gridview for each section, or is there a way to "categorize" the gridview to break up the data with a Section 1 Category

b
c
d
e
Section 2 Category

Web Forms :: Displaying Data Logic When Click On A Main Category
May 24, 2010I have a sidebar on a page with vertical navigation about products The navigation links are created from an xml sitemap with a repeater control using 2-level nodes with product main categories and subcategories I want to display the data so when i click on a main category the page will reload showing the underlying subcategories names and description in the main section (div) of the page, but also when i click a subcategory's name from the sidebar, i will get its products (names and description from an SqlDataSource) in the main section. (In the main section i'm probably going to use a DataList)
Can i do that ? Display different category level data depending on the link that was clicked or do i need a seperate "maincategories" page. The scenario is similar to the master-pages-and-site-navigation tutorial in the data-access tutorials but that one goes as far as presenting the main categories [URL]
