MS Office Forum / General MS InfoPath Questions / January 2006Alternative to UI.Alert
I have an InfoPath form that looks up some data in a database - that's all done in managed code behind the form. Sometimes it takes a few seconds, so I have a UI.Alert come up to tell the user the data is being looked up, and then another to say it's finished. This is not ideal because I would rather not have the user have to click on the OK button to clear the Alert and let the code continue. In Excel, I use Application.StatusBar to give the user the status of what my macro is doing. Is there such a thing I can do in InfoPath? Thanks, Beth A. Create a secondary .xml file with a status field in it. Place the status field in the view, and then instead of using Alert, just update the value of the status field, which will then display inline in the form.

Thanks Greg - this was really helpful, and like most good ideas, obvious once I read it! I put the field right into my schema rather than create a secondary one. The only problem is that I'm using managed code in the OnAfterChange event and it doesn't update the fields immediately on the form. Anyway to get it to update immediately. I tried to make a rule to do it, hoping that the rule would occur first. It doesn't seem to work though. I want the status field to be blank after the data has been retrieved from the secondary data source. Thanks, Beth A. > Create a secondary .xml file with a status field in it.

Yes, you are running into the issue where the view field is not refreshed until the function exits. There is a function that forces the view to update [ XDocument.View.ForceUpdate(); ]... but I don't recall having a whole lot of luck with it in situations like this either. Give it a try though and see if it helps. The problem, as I mentioned, is not that the field is not being updated, but that the view is not being refreshed--at least not until the function exits.

Place the status field in the view, and then instead of using Alert, just update the value of the status field, which will then display inline in the form. I've been trying to get the ForceUpdate method to work, but it's not doing anything. Will this work better if I go with the secondary datasource XML file and query from there? I didn't want to full around with all the extra machinery (especially figuring out how to access the secondary datasource in code), but I will if I have to.

Place the status field in the view, and then instead of using Alert, just update the value of the status field, which will then display inline in the form. As I said, I never had any luck with that either. It is completely a timing issue. The secondary data source will make no difference in this case. I don't think I've ever figured out how to make it work. One thing that might work (never tried it) is to have a custom task pane, and to do your messages in there. This probably doesn't have the same refresh issues that the main view has.

Thank you Greg - I got this to work with the custom task pane. I did it very simplisticly - made an HTML file with my message in Word, set it the task pane as invisible in the OnSwitchViews event handler. Then in my OnAfterChange handler, I make the custom task pane visible before running my "getdata" procedure, then invisible again at the end. That was quick way to do it - I would have to think harder if I wanted more than one message coming up, or other features of the custom task pane. Beth A. Perhaps not the most elegant solution, but I'm happy to hear that you got it working!
