How to validate multiple fields with c# custom code on button click before submitting

RegularMike — Tue, 29 Jul 2014 13:23:03 GMT

My main goal here is to pop up a validation box that lists which fields have not been populated(still empty) before allowing the user to submit. I know you can use the method built into InfoPath but some of my fields are People Pickers and that option is not available. Here is what I have been playing around with but am unable to get it to validate the field to be empty or not. It always ends up showing "Not Empty" even if I set a default value or enter a value in the field before pressing the button. This is just a test field, but I have over 10 fields I would like to compare.

Outline: -Get field value -Compare field to see if blank -Pop-up box with field name if blank -Do not allow submission if field is blank

Code:

public void CTRL51_Clicked(object sender, ClickedEventArgs e) { XPathNavigator nav = MainDataSource.CreateNavigator(); string fieldValue = nav.SelectSingleNode("/my:myFields/my:name", NamespaceManager).Value; if (string.IsNullOrEmpty(fieldValue) == true) { MessageBox.Show("EMPTY"); } else MessageBox.Show("Not Empty"); }

Any help would be appreciated. I am having trouble making this post read-able. I do not see any tools when posting this to change the spacing between lines. Here is a link to the same issue on another site if it's easier to read there: StackExchange.com
