Whenever I add this piece of code
I get this poping up next to my List Box(lstDataset) - I don't have a lstDatasetPanel within my project.
2715|updatePanel|ctl00_ctl00_ContentPlaceHolder1_lstDatasetPanel
What i'm doing is on change of a drop down I want to populate the list box with the data. When I try and change the drop down more then once it gives me this error:
"Microsoft JScript runtime error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ctl00_ContentPlaceHolder1_lstDatasetPanel'. If it is being updated dynamically then it must be inside another UpdatePanel."
Thank You
Jerry
