I am designing a calendar user control (I am aware one exists, it doesn't have enough functionality) in ASP.NET, but I am having problems accessing its public properties when it is instantiated.

To create the calendar, I programattically create a table during the Page_Load event. When each cell is added to the table, it is also added to a Hashtable so that I can easily access it later.

The properties I am having problems with access these hashtables.

The problem I am having is this: While I can use these properties sucessfully from within the control itself (for example, in the Page_Load event after the calendar is created), when I try to access these same properties from the page using the control, it fails with this error:

System.NullReferenceException: Object variable or With block variable not set.

I can post code if necessary. Thanks in advance.

I can't help with the specific problem your having- but why not inherit the calendar control and then extend it - rather than starting from scratch?

Hey,

Post code please. In addition, is Hal's recommendation not possible, for whatever reason?
