Drag Appointment Set Insert Parameter for SQL

I've made a lot of progress with the scheduler, but I am running into one issue.

I am working on scheduling physicians and they are either scheduled as a person or a group.

I have two seperate drop down boxes. One for physicians and one for groups.

I am able to display the appointment and return either the group name or physician name on the appointment box, but I have set a parameter for inserting or updating entries with a @Type parameter. @Type is defined in my c# code and works for all other function, except when dragging an appointment to another day. @Type sets whether the insertion was a physician or a group. When I do a report it will need to know if the ID stored is a physician ID or group ID. Based on that it will resolve group/physician names and create links.

Long story short I need to be able to define @Type insert parameter while the appointment is being moved to another day. The appointment wouldn't necessarily be the last appointment open, which is making it harder. The javascripting I've tried so far with OnClientAppointmentMoveEnd has caused the appointment to not be stored in SQL at all.

Getting a "Unable to get property 'documentElement' of undefined or null reference" error

I'm modifying one of our older ASP.NET WebForms apps that I've used Telerik AJAX controls in. While running the app in the VS 2010 debugger, I've started to get this error message:

"JavaScript runtime error: Unable to get property 'documentElement' of undefined or null reference"

It stops in Telerik.Web.UI.WebResource_4.axd code when I click on the RadDatePicker control. I've not modified that page in a very long time. If anything I've upgraded the Telerik ASP.NET AJAX controls, or at least I've downloaded them and installed them on my PC. If I run VS 2010 without the debugger and then click on the RadDatePicker control, I'll get a popup dialog box asking me if I want to use IE10's built in JavaScript debugger, because the same line is hit on. That line is:

var E = a.document.documentElement;

Which is in the getLocation: function (a)
(at least that's where I found it. That line of code maybe elsewhere.)

Bottom line: What's wrong and what can I do about it?

Hi,

When the colorpicker is located at the bottom of a page, it always cuts off the tabs at the bottom.

Se attached image from your demo!

Set "With a picker button" in the demo!

Error Creating Control - <ControlName> Object reference not set to an instance of an object

I'm just posting a solution an error I was getting in Visual Studio 2010 as I couldn't seem to find a solution in the Telerik forums when searching. Forgive me if it's already posted.

When in Design mode all of my telerik controls on the page were showing the error "Error Creating Control - <ControlName> Object reference not set to an instance of an object"

I googled this error and found the 'workaround' solution at this link here.

You basically have to go to the OnInit event of your page (or of the class your page is inheriting from) and surround your init code with a check to see if it's not in DesignMode. Once you have surrounded your code with this check, you must close your pages and rebuild the project to make it work.

here's the code example:

protected override void OnInit(EventArgs e)

{

if (!this.DesignMode)

{

//code here

}

This is a bug with Visual Studio 2010 and not Telerik.

Hope this helps someone.

Rad Scheduler

Hi Guys,

I am actually in the middle of building a community site which requires a month-view calendar which people can add events to and view when they click them.

I was actually going to use an embedded google calendar because Rad:Calendar only has a basic month view and as far as I know doesn't show events spanning multiple days like google calendar does.

When I saw Rad scheduler on telerik.com/quest I was delighted as It looks like it can do many of the same things but then I saw that it wasn't being released yet, so I have a few questions.

* Do you have a release date yet ?
* Will it show a month long view with mon-sun across the top and 4 rows for the weeks ?
* Will you be able to redirect the user to a different page when they click an event.
* will it show multi-day events in the same way as google calendar ? i.e. a box spanning across all the days.
* Will it be quick loading ?

Many thanks,

Jon

RadBinaryImage not working properly with Firefox 43.0.1

Hi There,

The RadBinaryImage in our application works well until Firefox upgraded to 43.0.1. Now the problem I am facing is that the image does not show unless I click or move the mouse on the page. I also noticed this issue only happens on gif files, not on jpeg files.

Here is the scenario: two pages included in this test demo, the first page has a linkbutton to open a radwindow, the second page is the RadBinaryImage to display a image file.

The following is my test code, please help, thank you.

get Pager value on the server

Hi

How do I get the value of the Pager on the server, .Pagesize always returns the initial page load page size.

What I'm trying to do is capture the users selected Pagesize in save it into their profile (I don't need the full persistence framework)

Also where should I do the setting of the page size, Did I read that it was to be done in the NeedDataSource event?
