Objectdatasource onupdating not firing

16 Feb

What I have done to narrow down the problem: (1) Replace Object Data Source with an equivalent Access Data Source : same problem.

(2) Check that sequence, parameter names and number of Bind("xxx") in Edit Item Template is identical to Object Data Source's parameter collection (3a) Create a new Test.aspx, using Access Data Source, update command works.

The following code snippet shows a more complete usage for the extender: The Image Control ID indicates the Image control, if any, that if clicked causes the panel to expand or collapse.

The Expanded Image and Collapsed Image properties set the URL of the images to use to expand and collapse.

The first code example demonstrates how to use a Drop Down List control, Text Box controls, and several Object Data Source objects to update data.

In addition to finding full-fledged server controls such as Reorder List and Accordion in the ACT, you find a bunch of other server controls designed to extend existing controls on the page and provide them with new and additional behaviors. NET pages are full of blocks of markup that, ideally, users would love to move around, collapse if too large, and expand on demand. In its simplest form, the Collapsible Panel extender looks like the following code sample: As usual, the Target Control ID property sets the target panel to expand or collapse.

Existing extenders can be categorized into a few groups: panel, input, popup, user interface, animation, and button. Expand Control ID and Collapse Control ID indicate the panel to use to expand and collapse the content panel.

When I finally resort to set the Update Method's parameter manually, everything works!

This is a strong evidence of such a possible exception.
