Hi !
I've got dropdownlists in ItemTemplates of a DataGrid. Those dropdownlists are meant to update other ones (within the same DataGridItem) The DataGrid is itself in a Repeater.
On the ItemDataBound event of the DataGrid, I populate the AjaxSettings collection of the RadAjaxManager control in the webform.
All the updates (AJAX PostBack calls) work very well but all dropdownlists on the page "flash" although they do not get updated (they're not meant to either !)....?! Some of the dropdowns flashing are not added to the AjaxSettings collection (on purpose)..... There are other controls on the webform (i.e. Labels) and they remain "static" so is the rest of the webform..... only dropdownlists disappear and re-appear after the AJAX Postback is completed.......
Is that behaviour "by design" ?! Can that be avoided ?!
Thank you !
Regards,
Benoit
