InfoPath Dev

Hello,

I've used a multiselect listbox in InfoPath 2013, it displays data from a SharePoint list. Is there a way I can write a rule to select/check and unselect/uncheck all items in the listbox with out any code.

 Would really appreciate a response on the same. Thanks

No, there really isn't. Multi-selects in InfoPath add nodes to the XML - the multi-select is bound to a repeating field, and when you click the checkbox, it adds a new instance of the repeating field. When you deselect, it removes it. You can test this by looking at the XML in a text editor. Unfortunately, InfoPath doesn't have any code-free way to add / delete repeating nodes.

Thanks Hilary. Would it be possible for you to share the C# or VB code to implement "Select All" and "Deselect All" functionalities for a multi select listbox.

Thanks as always!

You can find a code sample here: http://www.bizsupportonline.net/infopath2007/programmatically-select-all-items-multi-select-list-box.htm

Thanks, would be great if you can provide me a code for Deselect all in Multiselect listbox

But I did. I provided a link to a code sample - that should be all you need. Did you have issues implementing this in your form? If so, can you give me some specifics?
