I'm developing a custom module for DNN CE 7.0.1. The module contains a drop down (using DotNetNuke.Web.UI.WebControls.DnnComboBox) that has got thousands of items. So that the performance is not good.
Now I want to change the approach to load items into the drop down by loading items on demand instead of loading all items
Unfortunately, after turning on load on demand mode for the drop down as demo at: http://demos.telerik.com/aspnet-ajax/combobox/exam.... I realize that the drop down does not work well. There are some issues as below:
- Issue 1: drop down displays incorrectly on the first time clicking on the drop down
- Issue 2: drop down does not load data when scrolling down
I searched in the source code of DNN Platform 7.0.1 but I didn't see anywhere using load on demand mode for DnnComboBox.
Has anyone used load on demand mode for DnnComboBox? I would greatly appreciate it if someone can help to solve these issue
Thank you very much
