How can you tell if a value is contained in a specific column (let's say
column 1 named Status) of a ListView ?

In a list box you could go...

If ListBox1.Items.Contains(strWhatever) then

How would you accomplish this using a ListView ?

Click to expand...

Wouldn't that be off of subitem? It's been a log time since I worked with a
ListView.

I think each subitem represents data in a column.
 
Yes, I think it goes like this...

MsgBox(ListView1.Items(intCount).SubItems(0).Text)
MsgBox(ListView1.Items(intCount).SubItems(1).Text)

Thanks,

Rob,

As platinumBay you already showed, try to work with the data and not with
the controls as it is direct by a user typed in data.

I am working on a program that has many user defined controls within
flowlayout panels within tab controls....

I need a control that keeps track of each of these user defined controls and
their status. Only one user control may be "active" within a given flow
layout panel within a tab control. So in the unbound list view I keep a
"primary key" of the individual user control, as well as its status (2
separate columns).

When perfoming actions that change status, I iterate thru the list view to
make status changes.

I have figured out how to access the data now.

Is there a better way to do this ?

Thanks
 
Rob,

There are non binded controls, simple databinded controls (textbox etc),
complex databind controls combobox, datagrid etc.

Try the later for database work.

A listview is fore non database work. In fact it exist from endless
collections, keep in mind that the first column is very much different from
all the others. A listview has as well more ways it can be showed however
always with the first column on top. (it is just an older version of windows
explorer).

Here a sample we have more samples. Have a look as well to the treeview
because that is very much simular.

Thanks Cor,

But I think my question remains... Is using a non-bound ListView a good
control to use for keeping track of "active" controls in the situation I
present below ?

The scenario...
I need a control that keeps track of each of these user defined controls
and their status. Only one user control may be "active" within a given
flow layout panel within a tab control. So in the unbound list view I
keep a "primary key" of the individual user control, as well as its status
(2 separate columns).

Steve,

Hmmm...

This is a windows app. What is the specific downside of using a list view
for this ?

Basically, imagine a user control that has a Start and Stop button on it.
There could be 10 of these user controls sitting in a flow layout panel
inside of a tab control. Only 1 of these controls can have a Start button
"active" at any one point in time. Clicking a Start button on one of the
other 10 user controls "stops" the previously "started" user control and
activates the currently chosen user control.

Now that I think about it... I may be able to iterate thru all the controls
except for the chosen "Started" control and stop them without having to
update the List view.

Anyway... it is not necessarily a matter of viewing only one control at a
time. I did not make that clear.

Thanks for your input,

Rob
 
Rob,

I am not sure what you are doing. However if you want to keep track on form,
I would certainly look at that treeview. On the form the controls are mostly
build up to as a tree. If it is just in memory, than you have to explain
more, but certainly a control is than the worst solution.

Cor
 
Cor,

I would like to know "why" it is bad....

Maybe I am missing something, but as I open up new forms and user controls,
it becomes hard to know what the state of the control is in another location
(user control on a flow layout panel on a tab on another form)... the list
view has been set-up as a "Public Property" and is therefore accessible...

Thanks,
Rob
