I have a database that contains may appointments. I have written a search page that allows a user to specifiy dates and other parameters. Once the user initiates the search, I retrieve the appointments from the database and bind them to the radScheduler. That part is is working fine.

However, whenever the user hits the search button, I need to clear all the previously bound appointments from the scheduler so I can put the new results from the database into the scheduler. So, I called the Appointments.Clear() method but after a couple of seconds, it causes a javascript error. I thought that maybe I need to set some other properties like AllowDelete=true but nothing seems to help.

Here's is the offending line (I think):

rsScheduler.AllowDelete = true;
rsScheduler.Appointments.Clear();

    
            rsScheduler.AllowDelete = true;  
        
            rsScheduler.Appointments.Clear();

If this is NOT the correct way to remove all the appointments from the scheduler, please provide me with alternatives.

Thanks,

Dexter

RadDatePicker and RadAjaxManager1.FocusControl

quick question (can't seem to find an answer by searching)

I have a raddatepicker inside an AJAX panel everything on the form works fine, but I can't seem to set focus to it from the server side.

I can set focus to a radtextbox sitting directly beside the datepicker.

on the server side

This works
RadAjaxManaer.FocusControl(txtMyRadTextbox)

this does not work
RadAjaxManaer.FocusControl(rdpMyRadDatePicker)

any suggestions???

Using a dynamically populated TreeView in a ComboBox?

I want to use the TreeView control in a ComboBox but I want to dynamically populate the nodes in the tree rather than defining them statically in the web page. Do you have an example of this? My main problem is I don't understand how to access the tree control since it is in the itemTemplate of the ComboBox.

RadGrid localization problem
