I have been searching for an event to use while displaying in a label the total count of items in my listview. The label is ok but i've tried a list of events. non are working. Are there any suggested methods?

Do you mean... Label should display number of items in listview whenever Listview got added or removed any item?

yes, i've already done this. what i need is to get the count of the items once they're added or removed from the listview!

There is no event for an item being added/removed from a ListView. But there is something you can do about it...

You can create a new ListView control, deriving from ListView, and add a method to it for AddItem and RemoveItem. In these methods, you add/remove the item to the Items list, and raise your own event for an ItemsChanged or something similiar.

I apologize that I can't post code to do this, I'm not very good in VB. Hopefully somebody else can give you a working example, it doesn't take much code to do it.

Solution 2

create a timer from toolbox and set interval to 1000
under the tick_event of the timer1
just write this code

VB

Static x As Integer = 0
        If ListView1.Items.Count > x Then
            x += Val(ListView1.Items.Count - x)
        ElseIf ListView1.Items.Count < x Then
            x -= Val(x - ListView1.Items.Count)
        End If
        Label1.Text = x

please make sure you flag this as solved if it helped you....happy coding

Thanks for this but i cannot understand the ComboBox part. why ComboBox? i do not have a ComboBox on my form. just need to display total rows count (like 25 items) on a label anytime an item is added/remove from ListView.
