I am using the default advanced form template option in Visual Studio 2012.  I see it save to XML, but I need it to save to SQL "appointment" table.  As well as add a new textbox "CarrierText" and RadComboBox "ddlVendors" that lists values from SQL table.   I got this to work "showing  the new controls" except how do I access the values in my new textbox and RadComboxbox when the user hits "save" in the .aspx page RadScheduler1_AppointmentInsert.  NOTE: the textbox is directly added to the form advancedform.ascx and the RadComboBox is added to the ResourceControl.ascx

 tried getting the Carrier text below but no object found.
Private Sub RadScheduler1_FormCreated(sender As Object, e As SchedulerFormCreatedEventArgs) Handles RadScheduler1.FormCreated

If e.Container.Mode = SchedulerFormMode.AdvancedEdit OrElse e.Container.Mode = SchedulerFormMode.AdvancedInsert Then
_carrier = DirectCast(e.Container.FindControl("CarrierText"), RadTextBox)

End If

End Sub

I added a Loading Panel to a screen and it works find when running from the dev environment in vs2008 but when I move the changes to our test server I get
​Unknown server tag 'telerik:RadAjaxLoadinPanel' on the screen load.  The loading panel is being used on other pages with out issue.  Not sure what else needs to be moved to the test environment to fix this issue.

Hi and thanks in advance.

I created a custom control that uses a rad slider with item type set to item. As follows:


I am dynamically adding ticks on the server side. Here is the code:


The problem I am having is that the tick marks are showing once the radslider is rendered on the page. How can I hide these tick marks from showing? My understanding was that when you create an item type slider the tick marks go away, but this is not the case. Any help would be appreciated. I have included a screenshot for reference.
Thanks,

Hey guys we are running into two issues with the image manager and images hosted on external sites.  I've put together a demo video here that clearly shows both issues, but i will also write it out for others who come upon this post.

http://images.publicaster.com/ImageLibrary/Account116/Documents/ImageManagerIssue.mp4

For this demonstration, i'm using the latest version of the Telerik Ajax controls, v2013.3.1324.40, and i do specify a reference to the Editor Dialogs in my control declaration.

If you select an image in the editor that is hosted on a 3rd party, and then click the image manager icon in the editor, you get a message that says
"You are trying to navigate to a non-existing folder or you do not have proper permissions to view this folder.  Please, contact the administrator."

As you can see from my video, the image is hosted on a 3rd party site. I would like to know how i can disable this error message. 

If i click the "OK" button then  the image manager loads and i can see all the images in my image library.

The second issue is that i am unable to easily replace this image that is hosted on a 3rd party site with an image from my image library.  To reproduce,

1. select an image in the editor that is hosted on a 3rd party site.
2. click the image manager icon
3. click ok to dismiss the "non-existing folder" message
4. select any existing image from my image library
5. click insert button in the image library dialog

When you follow these steps, nothing happens.  the original image is still in place and the image i selected from the library is nowhere to be found.

I can workaround this issue by first deleting the image hosted on a 3rd party site and then inserting a new image from the image library.  This problem does not exist if i use an image that is already in my image library and replace it with an image in my image library.

Please advise how i can remedy these two issues.

Thanks

Hi,

I want to add a tooltip on a RadContextMenu.  This ContextMenu is displayed in a RadGrid, when we click on the red "X" (see photo in attachment).

I try this, but the tooltip is not displayed with the RadContextMenu (see code below).

I'm using the version 2013.3.1217.40
The RadGrid is in a userControl

Thank you

Steeve

Hi All,

I've implemented the following functionality in my RadGrid:
http://www.telerik.com/help/aspnet-ajax/grid-google-like-filtering.html

It works well, but it appears to auto-fill the entire value when a user would like to select a subset.  For example, if we have days of the week in the ComboBox the user would like to be able to type "sday" and get Wednesday and Thursday back.  Is this at all possible?

Also is there a way to implement a IsNull and IsNotNull functionality in these RadComboBoxes?

Thanks,
Mark

Hi All,

I have an editable Radgrid written in C# code-behind.  I'm curious if there's anyway to generate a change log of what users have inserted/updated/deleted and/or some sort of "Undo" mechanism.  Can anyone please help?

Thanks,
Mark

I have run into an issue trying to use the edit form template on a radgrid bound to an objectdatasource connected to a entity framework data model that uses complex types. It works fine when you edit an existing record but gives an error when adding a new record. Below is the code for a simple demo that I set up using a list of objects. In the below example if I edit a record it all works fine but if I add a record it throws an error "DataBinding: 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'person'.". Any ideas of a work around?
