Patrick,

>I'm doing a lot of work with ASP.NET and ASP.NET AJAX 1.0 and the .NET AJAX Toolkit.

>My requirement is to have a lot of fields appear and disappear based on dropdown values. This likely means setting BindingType = mmBindingType.None at runtime for hidden/unused input fields. Please clearing previously visible ones that go hidden :(
>
>My problem is that a dropdown value isn't getting bound, but I just discovered BindOnPostBack, and running tests to check how to use this. I've been using things like this.BindControl(this.ddMyDropDown) but something isn't working.

>Please more documentation or examples of using BindOnPostBack property. With sequence diagram, please.

>Also, a "MM.NET AJAX-Enabled Web Forms Template" project template would be helpful.
>
>Last, a "rules" sequence diagram would be nice, please. I figured out that HookPreSave() runs before CheckRulesHook(), which is great for data cleanup.
>
>I'm clearing blank values with field masks in HookPreSave() before rules fire, but this seems to be be something that should be handled by the control. I.e., for:
>

ajaxToolkit:MaskedEditExtender ClearMaskOnLostFocus="false"

>it would be helpful to have a property:

ClearMaskOnDataBind="true"
