How to clear selected items from a list box

[NeshaYU]

Hi,

I have a problem clearing the selected items fom a list box (MultiExtended). I have tried with:

listboxName.SelectedItems.Clear()

but nothig happens. When I loop and use GetSelected(x) and then RemoveAt(x) if GetSelected(x) = True I can remove selected items but only one by one. Can anybody please explain why listboxName.SelectedItems.Clear() is not working and show me the best and easiest way to clear all items that are selected on a list box by one click on a button?

Thanking you in advance

Mabe there is no better way.

There is two collection.
ObjectCollection
SelectedObjectCollection
istboxName.SelectedItems.Clear() just Removes all items from SelectedObjectCollection.
Removing itme from ObjectCollection must use ObjectCollection's methods.

Thanks for the reply. You maight be right. I solved the problem the other way, but it just don't make sence: what's the difference between listboxname.Items.Clear() and listboxname.SelectedItems.Clear()?

Nesha,

SelectedItems.Clear results in no items being selected.

Items.Clear results in no items remaining in the listbox.

To actually remove the selected items from the listbox, you could do something like this:

For i As Integer = (ListBox1.SelectedItems.Count - 1) To 0 Step -1
ListBox1.Items.Remove(ListBox1.SelectedItems(i))
Next

Thank you, this clears things. Also, this is much more elegant solution than mine.

Kerry,

Ran across that code. Hope you don't mind if I use this for my high school assignment. Much appreciation.

In so far as the thread is over a year old, I doubt any objections will be raised.

In addition, it really wouldn't matter how old it is.....the code is for public use.

Do you have any questions on the code?

this is the code for clearing the list box just by clicking once:
ListBox1.items.clear
