    Is there anyway to change the value of a hidden field during postback?
    I need to change the asp hidden field during a button click event, but the hidden field value doesn't get retained after the postback.

    The button is within a RadAjaxPanel.

    I added it to the RadAjaxPanel containing the button, and I also tried additing to RadAjaxManager (see below) but it didn't make any difference.

    <

     

    telerik:AjaxSetting AjaxControlID="Button" >

     

     

    <UpdatedControls>

     

     

    <telerik:AjaxUpdatedControl ControlID="hiddenfield" />

     

     

    </UpdatedControls>

     

     

    </telerik:AjaxSetting>

    Hi weezie,

    If you implement the functionality you request (using an asp button to update an asp hidden field) with regular posbacks, the same code should work with RadAjaxManager or RadAjaxPanel which transform the postbacks into ajax request. You merely need to make sure that you ajaxify the button and the hidden field using either ajax manager or ajax panel but not both at the same time.

    Test your code with plain postbacks and then ajaxify the configuration and let us know how it goes.

    Best regards,
