Hi all, yesterday I tried to use CascadingDropDown extender for the first time and it didnt work. I have closely followed both the video tutorial and the sample website. I have 2 chained dropdownlists, 1 of them is supposed to be disabled until the other is selected right? However, when I run the web app, both of the dropdownlists are enabled from beginning, selecting value in the parent DDL doesnt load the values in the child DDL.
So I downloaded the code from the official ASP.net tutorial to see what I have done wrong. To my surprise, the sample website didnt work either, showing the same symptom! I downloaded and installed the latest Toolkit but that did not help. Does anyone know what is happening?
Thanks,
Phuong.
By the way, the webmethod that populates data into the parent dropdownlist did work. The parent dropdownlist did get the correct data.
Please help!
Hi Phuong,
It's hard to tell the reason since the sample code doesn't work too.
The only suggestion I can make is downloading the most recent AjaxControlToolKit and sample and try again.
