Hello,
I am using Q3 2009 controls and running in IE7. I am attempting to use the scheduler but am experiencing some weird problems. Here is the code for the test project I created:

                        row["subject"] = "CALL"; 
        
                        row["start"] = (new DateTime(2010, 6, 15, 13, 0, 0)).ToString(); 
        
                        row["end"] = (new DateTime(2010, 6, 15, 16, 0, 0)).ToString(); 
        
                        callBackTable.Rows.Add(row);

                } 
        
            }

The scheduler renders ok and I can see the hard-coded appointment appear, but when I double click to edit it, the start and end date textboxes flash red (with error symbol) and then return to normal, and then the subject box's error symbol appears, as if it failed validation. I get the following javascript error in IE when this happens:
ValidatorUpdateDisplay is undefined
Code: 0
I can still close the appointment with the 'x' in the top right corner of the edit form, but the 'Save' and 'Cancel' buttons do not work.

If I double-click on a blank timeslot, add some text, and then click 'Options', the error symbol does not appear but I get the script error "'null' is null or not an object".

After searching the forums, I found a few suggestions to place a dummy validator on the page which does not actually validate anything. This has had no effect. Any help will be appreciated. Thank you.

Hi Josh,

We tried to reproduce the problem you described, but without much success. Please find attached our test page and a movie as part of our local tests.
Does it work at your end?

I am receiving the same error in IE8 with RadScheduler but it seems to think there is a problem with the WebResource.axd. See attached for debug info and here is the httpHandlers section of my web.config. Is there something wrong with this?

<httpHandlers>

<add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />

</httpHandlers>

Thanks,

Don

Try adding this inside httpHandlers:

<add verb="*" path="*.asmx" validate="false" type=

"System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

/>

<add verb="*" path="*_AppService.axd" validate="false" type=

"System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

/>

<add verb="GET,HEAD" path="ScriptResource.axd" type=

"System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

validate="false" />

When I added this in my web.config I stopped getting the error in IE7. I haven't tested in IE8 yet.
