Hi,

I post an example of extended function for JQuery embeded in Telrik RadControl.

Before you must add in your marster page or page the declaration of JQuery like this:

After this, you add the reference the javascript file in the ScriptManger.
You can donwload this script at this link

Then remane the variable "$" in the script by "$telerik.$".

Now you can add extended function to JQuery.

Where can I find RadComboBoxContext and RadComboBoxData classes?

Refering to this example: http://www.telerik.com/help/aspnet-ajax/combobox-loading-items-from-wcf-service.html

They don't exist in the Telerik.Web.UI.dll assembly apparently.

Any help is much appreciated.

 

 

 

 

See what's new and download from your accounts.

Enjoy!

I have a RadComboBox on my page:
<telerik:RadComboBox ID="RadComboBoxProduct" runat="server" Height="200px" Width="200px"
                            DropDownWidth="298px" EmptyMessage="Choose a Product" />

I have populated its data at run time, client name as text and clientId as value.

How can I get the selectedItem value using javascript?

function getSelectedValue(radComboBox)
{
// how to implement this?
}

Any help is much appreciated.

I'm a complete newbie and i've just begun upgrading RadBar to RadMenu. I seem to get this error....

Error    6    Literal content ('<telerik:RadMenuItem Text="Hours" BorderStyle"None" NavigateUrl="~/hours">      </telerik:RadMenuItem>') is not allowed within a 'Telerik.Web.UI.RadMenuItemCollection'.   

Any explanations or suggestions as to get rid of this??
