Hi,
I want to retrieve the hierarchical structure which is store inside
the database and then display it using treeview control. But now I
got a design issue which I hope that you guys can help me. My
hierarchical structure has five levels which is store in table call
level1, level2,… level5. Each level remember the parent ID e.g. level5
contains a column called level4ID. How should I implement it in order
to get fastest loading?...

Hello!
I have an urgent problem concerning ASP.NET, ADO.NET, SQL Server, XML and
the TreeView control.
I have two tables; one describing the products and one describing their
relationships. A product may consist of multiple other products. So far
everything is great. But one product may exist as a subproduct to multiple
parent products.
My tables:

Hi,
I want to store product categories in my db and am a little lost as to where
to start.
They can be hierarchical, such as "Books" > "Cook Books", so my table is
like this:
int CategoryId
int ParentCategoryId Nullable

I want to display a hierarchical listing of items from a database
table, where, say, each row in the table has an "ID" field and a
"parent_id" field giving the ID of its parent (NULL if it's at the top
level of the hierarchy) -- like message posts and their replies. Is
there a built-in way to do this, or a generally accepted simplest way?
My first idea was to create a user control like HierarchicalListing
that contains a Repeater, and...

Hi,
I have some hierarchical data (FAQs) that I would like to bind to. The basic
structure is:
FAQ Category
+ Categories
+ FAQs
So an FAQ category has any number of sub-categories and any number of FAQs.

In a previous version of vb I used to save and load hierarchical data
from an Access db into a treeview. But, I never found a very
satisfying or elegant way to do it. I used a flat file approach with
each item having a reference to its parent node. I would then start
by loading the top level nodes folowed by loading child node data only
as their parent node was expanded.
This method worked fairly well except that allowing the user to...

I need a control to display a hierarchical tree of data and each node in the
tree should have a checbox to select / unselect that part of the tree.
Selecting / unselecting a top node should select / unselect all the
children.
What kind of control is best fit for this? Any samples?

Hi there.
I am trying to find th best way (best UI control) to present hierarchical
data, nested tables. For example, I have a Employees table (id, name) and
EmployeesSales (id, idEmp, description, value).
I want to show this in an hierarchical mode, so I tried DataGrid control.
However, as I read somewhere, this DataGrid can only show one table at a
time, i.e., when I click "plus" sign, I have only a link to the
EmployeesSales table.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
