linking drop down box with value in tree control

[esebastian]

Hello All,
I am using infopath 2007 and am hosting the infopath form using the
form control in a windows application in visual studio 2005. In my
windows project i have a tree view control, what i would like to do is
after the treeview node is selected i want to match the text on the
selected node to the text in a drop down box that is on my infopath
form, the dropdown box is populated from the same database as the tree
control.

Here is a visual example.

TreeControl Drop Down Box on infopath form

1 1
2 2
3 3
4 4
5 5

lets say the user selected node with text # 3 on the tree control, i
want the selected item of the dropdown box to change to 3 to reflect
the selection on the treecontrol..

anyone know how to do this?
Erin

In your hosting application, you have access to the DOM of the infopath form.
The dropdown is bound to some value in the DOM; if you change the value of
that DOM node, the selected value in the dropdown will change, too.

Hi Alex,
Thanks so much for your reply.
OK so i figured out that i can set the value of the DOM but what i
want to do however i want to be able to only select whatever values
are available in the drop down box itself. So for instance, if i
select 5 from a tree control and the value 5 does not exist in the
drop down box i don't want it to show up in the DropDownbox, in that
case i want to display a message or something along those lines
alerting the user that this value cannot be selected. Can this be
done??

If the drop down box is being populated from a source (either main data
source or secondary data source), you can look up the value in the list of
values and return a message if the value cannot be found.

Since you've been posting the answers to all of your unanswered questions in
this newsgroup, I wrote a possible solution to this problem for you (I do not
do this often ). See
http://enterprise-solutions.swits.n...em-does-not-exist-in-combo-box&c=infopath2007

While I wrote the solution for a combo box, it should also work for a
drop-down list box.

I have tried to reply to this message a few times without the reply
going through on this end so if you see more than one reply -- so
sorry.

Thanks so much S.Y.M, the above worked famously!!! I do have a
question for you though. My form has a few comboboxes on it and the
combo boxes have many entries in them, up to 50-60 each... I am
wondering if we can put the Entries fields somewhere else, like in a
secondary data source, if we put them all in the main data source ,
the main data source is going to be HUGE... any wisdom to push my way
on this one???
Thanks,
Erin

Absolutely! The solution would work equally well if you used secondary data
sources. The whole idea behind this solution is that there must be a list of
items somewhere that can be checked against. If the items are static, that
is, if you entered them manually into the drop-down, then there would be no
such list. So the items have to be stored either in the main data source or a
secondary data source, whichever suits you best.

It Works!!!
Thanks so much!
