[omidaghakhani1368]

Hi.
I add item to listview and i can handle selected index of listview
But when i have a one item in listview and if i select it,event of listview execute
but when again click on item,event of listview not execute

The event only fires when the selected index has changed.

You can add custom views to the list and then handle their events instead.

I know.It's working good when item count is above 1 item,
But in one item not work if once click on item
I think that if i add blank item to listview then it is ok,isn't?

It is probably considered selected before you clicked it. Check the value of SelectedIndex. Try to set it to -1.

OK thank you

is there a similar solution for a treeview_SelectedItemChanged event?
First click fires.
Second not - for sure.
How can i "Clear" the Index for the Item?

Note that you should have started a new thread for this question.

Try this:

Dim jo As JavaObject = TreeView1
jo.RunMethodJO("getSelectionModel", Null).RunMethod("clearSelection", Null)

Thank you Erel,

that is the right direction for me.

A little trap hint for all who are interested:
Because of the listener is allready working, the "clearSelection" Method fires the "treeview1_SelectedItemChanged" Event with Selection= -1, which
could cause an Exeption if not intercepted.
