This is my first attempt at inheritance, and it seems to be working okay, but I want to be able to assign a back color to visual show that the sub-item has been selected (new property I gave it). I used the Reflector to see how the code is done on the original ListViewSubItem, but I can do it the same as, as they assign the back color to the SubItemStyle, and I can't get to that since it's protected. Is there any other way to do what I want, or am I out of luck? Thanks in advance.

Thanks you! This has been bugging me for a couple of weeks. I don't know how I missed that property of the ListViewItem, but it seems to be what I'm looking for.

I have 2 classes
class Attribute<t>
{
string attributeID;
T[] values;
}
When instantiated, it holds several int's, decimals or strings
2nd class should hold several DIFFERENT Attributes. Here I am getting problem:
class Node
{
ArrayList attribArray;
AddAttribute(Attribute<t> inAttrib)
{ attribArray.Add(inAttrib;}
}
It compiles, but I cannot find a way to get stored Attributes
runtime
Example: I need a list of values from 2nd attribute in
my attribArray
Any thoughts, please

hi,
1.
when retrieving an item from an ArrayList you need to cast to the original type.
string str1="aha";
ArrayList list=new ArrayList();
list.Add(str1);
string str2=(string)list[0];
2.
when storing different types in a generic, you need to specify a common type
(it could be object or any common ancestor of your types).
3.
since an ArrayList is not an array, I would not call one instance attribArray,
I would suggest either attribList or attribs.

>1.when retrieving an item from an ArrayList you need to cast to the original type.
I know that. Two issues though: (a) where to get information on the type of stored Attribute
(b) how to succesfully unbox object to Attribute<int>, Attribute<string> etc.
>2.when storing different types in a generic, you need to specify a common type
(it could be object or any common ancestor of your types).
I thought that adding an onject to an ArrayList does it automaticaally (I mean conversion to the Object type)
>3.
I am not going into this
SO, I am still in limbo. Thank you for trying to help me

Hi,
1.
you can retrieve an object from any ArrayList, then check its type, e.g.
object obj=list[0];
Button btn=obj as Button;
if (btn!=null) btn.PerformClick();
2.
ArrayList does not care about the types of objects it is holding.
A generic collection such as List<T> is different:
- it will only accept objects of type T (or derived from T)
- it will automatically return objects of type T, without needing a cast
(making it both safer and faster).

if (btn!=null) btn.PerformClick();
(a) my objects are Attribute<int>>, Attribute<string> etc. Should I try to cast all variety?
(b) to my great surprise, when I did your line 1 it did return an object with type name
"<assemblyname>.Attribute`1". Here 1 stays for 1 parameter. Moreover, FullName showed this parameter type like String.string in my case
Oh, Mighty Reflection,, the problem is solved
2. I cannot use List<T>, can i? My objects are all different types
thanks

Thank you Giorgi for the link, I checked out the link, but it uses Reporting Services. and I don't want to use Reporting Services.
My application is actually a Point of Sale which prints the Transaction Bills (embedded report).
Showing the report in the reportviewer and then showing the print dialog irritates the user
alternately, is there any way to print the report to the default printer without showing print dialog.
thank you once again.

I am trying to datasource a gridview within a repeater. I am having issues passing the data from the repeater to the gridview (either to source it manually or set the Gridview's SQLDataSource attributes wtihin the Repeater_ItemDataBound event.)
The XML will look similar to this (all dummy data):
<root>
<Unit type="District" number="221">
<Employee name="Joe Smith" unitType="Store" unitNum="2213" reviewStatus="Pending" empNum="12345"></Employee>
<Employee name="James Jones" unitType="Store" unitNum="2365" reviewStatus="Pending" empNum="23654"></Employee>
</Unit>
<Unit type="District" number="254">
<Employee name="Rosie Worcester" unitType="Store" unitNum="2369" reviewStatus="Pending" empNum="26358"></Employee>
<Employee name="George Washington" unitType="Area" unitNum="254" reviewStatus="Pending" empNum="95682"></Employee>
</Unit>
</root>
I need an asp:Label within the repeater to load the <Unit> type and number and then pass the employee information to the gridview. Any suggestions on how I might do this? I cannot directly access the Gridview or SQLDataSource within the Repeater_ItemDataBound event.
Thanks in advance!!

I have a dateTimePicker control on my form and I am working on a payroll entry form. I want the datetimepicker to default to the following sunday for the period ending date, if the user selects a day during the week. does anyone have any suggestions on how i could do this using the ValueChanged event?
Thanks

DateTime dt=DateTimePicker.Value;
dt=dt.AddDays((7-dt.DayOfWeek)%7);

That worked wonders, I can even use the same logic to grab the beginning of the week.

Hi all!
I have a class like this:
class A<br />
{<br />
private string strA;<br />
private B mySubclass = new B();<br />
...<br />
<br />
class B<br />
{<br />
public B()<br />
{<br />
string strB = strA
}<br />
}<br />
}
Is there a way to make strA visible only for class B and not for other classes? If not can you suggest a workaround to do that?
Thank you.

You could... pass a reference to your strA to class B through its constructor.
Or, you could probably do something with delegates. I must check up on delegates one day.

Thank you! I thought to do that too. It seems to be the simplest way to obtain that I asked
Hope that helps!

Do rate the reply, if it helps or even if it doesnot, because it helps the members to know, what solved the issue. Thanks!

If it actually was a subclass, you could just make the string protected.
As B is not a subclass at all, you can't do that. You have to pass a reference to the instance of the class.
Experience is the sum of all the mistakes you have done.

Thank you for the answer! And how can I do to make B a "real" subclass?

Inherit from the A class:
class B : A {

}
