I would like to provide the user with the ability to cancel the=
change of an index in a ListView (for instance if there is data=
that has changed related to the ListView, etc=2E)=2E=2E=2Eand I have=
been able to get the code shown below to do this, but everytime=
the user indicates that he/she would like to revert to the=
original selection they get prompted a second time and have to=
indicate so again before the process will successfully=
complete=2E
Now=2E=2E=2EI am aware of the fact that the SelectedIndexChanged event=
gets called twice when the index changes - I have tried to=
handle that by checking for the number of SelectedIndices=2E I=
have also added a user defined variable ("ListInitialized") that=
causes code in the SelectedIndexChanged event handler to be=
skipped when set to false=2E
A few notes about the code=2E listView1 is a simple ListView with=
two items in the collection each of which has one sub-item=
(names or contents of items and sub-items can be anything you=
want)=2E Multi-select is set to false (I am only dealing with one=
selected item at a time here)=2E HideSelection is set to false=
(because I am allowing the user to edit other fields and always=
want the selection displayed)=2E View is set to "details" (so I=
can see the sub-items)=2E FullRowSelect is set to true (each item=
is treated as a single entry)=2E
Can anyone tell me what is happening here? How can I get this=
code to work so that a user can cancel his/her entry without=
having to go through the cancellation process twice?
Thanks in advance=2E
