I have a timer and try to update a label ontick using ajaxmanager
<telerik:AjaxSetting AjaxControlID="TimerUpdate">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="TimerUpdate"/>
<telerik:AjaxUpdatedControl ControlID="LblWatchList"/>
</UpdatedControls>
</telerik:AjaxSetting>
It gives me, The method or operation is not implemented.
[NotImplementedException: The method or operation is not implemented.]
System.Web.UI.Timer.set_Visible(Boolean value) +54
it seems like RADAjaxmanager is trying to set visiability of a control regardless it has a visiable property or not, and it through an exception.
do i have to put them into RADAjaxPanel? thanx
