Hello All,
I am working to create a generic datagrid which accepts a
datasource(ListData - This is our own datatype) and depending on the calling
program customizes itself for sorting, paginantion or accepting the add and
remove item events.
What i am observing is that none of the vents are happening... (Sort, page,
or item). I am sure I am missing something basic here... Need help... Thanks
much

Hi there,
According to documentation I read the ArrayList.IndexOf method uses the
Object.Equals method to loop through the items in its list and locate the
first index of an item that returns True.
Therefore, overriding the Equals method in the class definition of the items
I put in the ArrayList should make the IndexOf method use my version of the
Equals method?!

From reading the documentation, this should be a relatively easy thing. I
have an arraylist of custom class instances which I want to search with
an"indexof" where I'm passing an instance if the class where only the
"searched" property has a value. I expected to get the index into the
arraylist where I could then get the entire class instance. However, the
'indexof' is never calling my overloaded, overrides Equals method. Here is

I'm trying to derive a class from ArrayList. When I try to use the
Overrides keyword on the Item property, the IDE underlines Item in my
Function definition and says "Item conflicts with a property by the same
name declared in ArrayList"... what gives? Am I out to lunch? I should
add that I'm still a little new to OO and inheritance, polymorphism, etc,
and would really like to understand this...
Here's my code:

Hello,
I have an arraylist that loads a checkboxlist. I populate the arraylist
using a custom class and pulling the data from the web.config file. When the
checkboxlist is loaded, only the last item in the list is displayed for each
item, in other words, item #4 is displayed 4 times. My code is below.
Thanks

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
