asp.net custom templated datalist - throws argument out of range (index) on button press
- by MrTortoise
I have a class BaseTemplate
public abstract class BaseTemplate : ITemplate
This adds the controls, and provides abstract methods to implement in the inheriting class. The inheriting class then adds its html according to its data source and manages the data binding.
this all works fine - I get the control appearing with properly parsed html.
the problem is that the base class adds controls into the template that have their own CommandName arguments ... the idea is that the class that implements the custom templated dataList will provide the logic of setting the Selected and Edit Indexes. This class also manages the data binding etc. It sets all of the templates ont he datalist in the Init method (which was another cause of this exception).
the exception gets throw when i hit one of these buttons .. but after the ItemCommand event is being processed. The stack trace does not include any references to my methods or objects which is why i am so stuck.
