MS Office Forum / General MS InfoPath Questions / February 2007linking drop down box with value in tree control
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. > Hello All, > I am using infopath 2007 and am hosting the infopath form using the [quoted text clipped - 21 lines] > anyone know how to do this? > Erin 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.net/infopath2007/article.php?t=display-message -box-when-item-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. --- S.Y.M.

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. --- S.Y.M.
