Change data structure of UltraWebGrid during AJAX callback
posted

I have a grid on a page that can contain various data structures depending on the node selected in a tree control on the page.  I would like to change the underlying data structure of the grid without causing an asynchronous postback.

Is it possible to change the underlying data structure, update the column headers and update the rows of an UltraWebGrid during an AJAX callback?

    It is not possible to alter the structure of WebGrid (most particularly including bands and columns) during an AJAX callback generated through its built-in AJAX capabilities.  Most of the grid's AJAX callbacks update a single row at a time, so a mass-update of the rows is typically also not possible.

    ... you can change the structure during the refresh of a WARP panel if you place the grid inside of it..

    This is the best option available.  If you have the grid's AJAX disabled, you could use either a WARP or an UpdatePanel.
