Hi,
I need to create a simple parent/child hierarchical menu. I have alread used
the Treeview control but my requirement is slightly different than the
Treeview control. I already have the kind of menu I am talking about,
written in Classic ASP, but I need to write the entire menu thing in Asp.Net
using CSharp.
I have a Sql table which has large number of menu items with problemId and
parentId, through which I am trying to create and display a menu control.
But when I load the page I want to display only the parent items and not
child items, which I have done already and it is fine. Now, what I want is,
since the parent items are displayed with a right arrow button indicating
that if the user clicks on those button which has the right arrow, then they
will be able to see the Children items of that particular parent item. And
then if the parent item has many children being parent to other children
then they also should have the right arrow which will then display if it has
any children.
The scenario is what I have written above. What I am struggling to do here
is that, when I click on the parent item, I get the Children item in a
different page. But what I want is like the following, in the same page.
Parent 1
Children 1 - Parent 1
Children 2
Children 4 - Parent 2
Children 5
Children 6
Children 7
Parent 2
Parent 3
Parent 4
And as I load the parent items initially, I want to load the Child items
depending upon which parent item the user clicked, and I don't want to load
all the parent/child items when the page is loading since the data is too
heavy.
I have been looking in the forums and other resources to get an idea to
program this kind of menu, but I have been only little successful. So any
help or links to any other resources or articles is very much appreciated.
