I am using a rad tree to display a list of clickable menu items. But half of the time when i perform a click i get this:

1. Uncaught Sys.ParameterCountException: Sys.ParameterCountException: Parameter count mismatch. ScriptResource.axd:222

I navigated in the console to RadTreeView._postClickCommand and the method "h._getHierarchicalIndex()" appears to be returning the correct parameters (ex 0:0:1)
I am using version 2012.1.411.35 of Web.UI and i have a RadAjaxManager and ScriptManager on the page.

I have been scratching my head on this for a few hours now and i have no clue what to do.  For some reason, in my project, i am having a problem accessing client-side api's for radcontrols.  Below is a screenshot of my javascript error and code.  All i am doing is calling a webservice, obtaining json, and then trying to populate the grid control with the json array.

Hi Telerik,

On Clicking the logout button, I am displaying a confirm box. If the user press yes, then logged out. I tried the following code in the OnClientClicked event but I am getting some sort of JavaScript error in IE. In Firefox nothing happen. Please inspect the below code and guide me.
function OnClientClicked(sender, eventArgs)
{
    eventArgs.set_cancel(!confirm("Confirm logout?"));
}

Thanks to all,

Hi

I'm working on moving some of our grids from using the auto generated edit forms to using Form Templates, but still using the markup for defining the CRUD operations using the SqlDataSource.
The grids already use asp:SqlDataSource for the CRUD operations and have been working fine with the auto-generated edit forms.

I've now changed the markups and added the FormTemplate which shows the insert / edit form as expected, including binding the column values correctly when editing, but the insert / update operations do not work from these forms.

When I try to insert a record, it simply creates a record with NULL values.
When I try to update  record, I get the following error (I have the ConflictDetection set to CompareAllValues):
  "You have specified that your update command compares all values on SqlDataSource 'sqlOperatorNotes', but the dictionary passed in for oldValues is empty.  Pass in a valid dictionary for update or change your mode to OverwriteChanges"

Seems like the control values are not being passed from the edit/insert form to the sqldatasourc.
Do I need to change anything more to switch from auto generated edit forms to FormTemplates.

Here's part of the formtemplate:

Here's the corresponding grid column

Hi, as attached you will see some strange behaviour of the radeditor in IE9.
As you will see, the toolbar is rendered as a bulleted list, but i have no custom skin or css added, that uses OL or UL styling tags

The same page works in Chrome, Firefox and IE10

Do you have some idea it could be? Does it have something to do with a css that i don't know off or what?


This is the markup:

<telerik:RadEditor ID="DescriptionTextBox" runat="server">

     <Content>

                    MyContent

     </Content>

 </telerik:RadEditor>

Thx

I have a radgrid where we wish to have 4 frozen columns and allow users to group one or more of those columns.  In the following example, everything is fin un-grouped.  I can scroll right and see all the columns.  However, when I drag a column and group, the horizontal scroll bar disappears.  How do I fix this issue?      

Hi there.
After some good support here to customize the RadMenu bar in terms of appearance, I face a problem in IE7 where the menu items do not appear to slide out/show them but in IE8 and 9 they work perfectly. Any ideas? Here is the relevant code:

Hi there.
I am using RADMenus to dynamically populate menu items. This works fine and I can see it slide out in IE8 and IE9 no problem.
In IE7, this does not seem to show. I can kind of see it sliding out but seems like the menu items are hidden somewhere.

Any ideas how I can fix this? Here is the relevant code:

Hi guys,

Is there any way we can set Selected Items or Checked Items in a multiselect RadComboBox ?.

I tried following code but that works only if it is not a multiselect RadComboBox.

RadComboBox.SelectedValue = "123"

Edit : Also I am setting value on post back in vb.net

Thanks,
Rahul

I started another thread here:
http://www.telerik.com/community/forums/aspnet-ajax/calendar/skin-error-when-deploying.aspx
But now I have a different problem.

Now it locks up the PC and will not let me publish the project.  I have deleted all of the project files on the server and tried several times to publish and it stops on the bin folder but gives no error.  I can't delete the dll from the bin folder because it says it's in use.

I've had it.  I really like the Telerik controls but it seems between all our developers they are nothing but trouble.  I'm not the first to have this problem.  My other developer has to publish his project to his PC, then hand copies the files up.  Now he refuses to use any of the controls.
As Sr. developer for our plant I'm starting to agree.

My new error from the web server is this when I try to run the project after uploading:
Could not load file or assembly 'Telerik.Web.UI.Skins' or one of its dependencies. The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020)

I have rebooted my pc and tried again.  The problems started when I added a reference to the Telerik.Web.UI.Skins.dll so I could use a skin.

What exactly are the steps please to getting these skins to work?  And please don't point me to the tutorials.  We've read them and have tried them all.  Are missing a step?

Here's what we did:
I added the datetime picker control to the project.  When I try to select a skin it tells me I need to go copy the dll from another place on the drive to by bin folder. (Why this isn't automatic, I don't know)
I go to c:\program files....  and finally get the skin dll file and copy it to my project's bin filder.
Then it will let me add the skin.
Now when I publish the project it can't find the skin again on the server and it tells me to add a reference to the dll in visual studio.
I add the reference to the dll in the bin folder.  (Now the trouble begins)
The project refuses to publish correctly and the dll gets tied up somehow so I rebooted my PC.
Nothing helps until I remove the reference and throw away the skin.  Then maybe it starts working again.

Where did we go wrong?
