I am currently using an embedded webCombo as a Column Editor for my ultrawebgrid, however, when I build the dataset and assign it to the combo's datasource to perform the databinding, the page load takes an eternity to actually show the page's content. I know it has to do with the combo's databinding because when I commentarize this, everything goes ok.
Not everuthing is bad, the combo works fine with something around 30 rows worth of data (2 to 5 columns), but when my DataSource has 50 - 100 rows, everything kinda' crashes. So, is it it's normal behaviour? Is that why we have paging and XmlLoadOnDemand? Is there another way to optimize the app sp that the page can be loaded faster and the combo has all of it's data always available?
Any guidance is appreciated. Thanks.
Hi Dave. Thanks for your response. I have also tried XmlLoadOnDemand as well as paging and the difference I see is whenever a postback occurs, then the page is loaded a lot faster, but the first time the page loas, it is just as slow as it did without any of those settings. So I'm experiencing not much of an improvement with those.
I have seen that IG people says that it's way too different having a regular html select control than having the webCombo which actually displays an html table inside. In my case I'd love to have just an 'embeddable select'. I have tried to embed some control but I have always given up on that, since other than the IProvidesEmbeddableEditor interface, there has to be a lot of exposed javascript methods, but IG documentation just goes as far as a simple 'Here's how it's done in WebDateChooser', but I guess that's another question.
Kind regards.
I think that this is related to the question that I asked a couple of days ago titled "WebCombo with lots of rows".
I see exactly the behavior that you describe and it does depend on the number of rows in the combo list. The combo doesn't need to be in a grid for this to crop up.
I've set XmlLoadOnDemand=Accumulative and handled the InitializeDataSource event. That helps a lot, but the scroll box in the combo list doesn't behave the way that I would like...
So far, no responses to my request.
