Workflow Soluiton

Is there a way to clear the selected listboxcomponent in between page refreshes? I am using a dynamic update panel with a refresh button. When I select something from the listboxcomponent and then change my search criteria so that the listboxcomponent array has less values than the selected index it throws the following error:

"Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"

Here is an example to make this more clear: I am searching for AD users, the input is a text box where a last name is entered and the search is lastname*.

Search1:back
This only returns 2 values, I dont select any.

Search2: ba
I select the 8th user in the listboxcomponent

Search3: back
I receive an application error.

depending on how you're populating the list box, you can use the "initialize data" component in front of a dynamic model to clear the list box variables each time the box loads. i usually put it right after the start component and declare all my variables there. just use a blank or empty value for the variables when you initialize them. so lets assume you're populating the list box with constant values. take those values and initialize them as a text array (for example) in a dynamic model instead. also in the initialize data component, add a blank value for the listbox's OUTPUT value as well. this will force the selected item to be cleared on list load. hope that helps you friend!

Africo,

I am not sure I completely understand what you are saying. Right now I am setting the values in the listbox in a dynamic model.

Thanks!

i decided the easiest way to do this is to just put a javascript action in the Refresh button.  see if that'll work for you.

set the Control ID on the listbox to something like "listBoxTest", as below

add a custom event to the Refresh button - 
onclick
listBoxTest.selectedIndex = -1;

i've added an example package to this reply.

Thank you for the detailed steps. The solution worked perfectly!

Dustin,

I'll put together a workflow demo package for you to show you what i mean.
