Hi Telerik

I am dynamically displaying a radwindow using javascript. In the JS I am only setting the position to center but on rendering I am getting a JS error Style is null.

var winemp =$find("<%= RadWindowEmp.ClientID%>");
function showemp(sender, args)
{
winemp.center();
winemp.show();
}

showemp() is invoked on a radbutton clients click.

Thanks
Damian.

Simple multiselect

Hi,

When using the RadListbox with SelectionMode set to Multiple, is it possible to allow users to select multiple items just by clicking (without having to hold Ctrl). This used to be an option with listboxes (options were Simple or Extended) in MS Access but I can't find an ASP.NET listbox with allows this?

Drag and drop between resources

Hello,

I need to use RadScheduler in a similar use case to this demo where you can drag unresourced tasks to the scheduler.

http://demos.telerik.com/aspnet-ajax/scheduler/examples/draganddropintegration/defaultcs.aspx?product=scheduler

However, I need to drop the tasks directly to resources. Basically, I want to combine that demo with the customized header menu (http://demos.telerik.com/aspnet-ajax/scheduler/examples/resourceheadertemplates/defaultcs.aspx).

How could this be achieved?
I already have implemented the header menu and some of the drag and drop capabilities (only determining the resource is missing).

[Solved] RadDropDownList does not exist in the namespace Telerik.Web.UI

When using RadDropDownList control I get the following error:

Error 1 The type or namespace name 'RadDropDownList' does not exist in the namespace 'Telerik.Web.UI' (are you missing an assembly reference?)

This is a piece of the code:

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<telerik:RadDropDownList runat="server" ID="DropDownListCuadroMandos" TabIndex="1" Width="200" DropDownWidth="200" DefaultMessage="Select one ..."

DataSourceID="SqlDataSource1" DataTextField="Descripcion" DataValueField="IdIndicador">

</telerik:RadDropDownList>

The reference to the assembly is located at:
C:\Program Files (x86)\Telerik\RadControls for ASP.NET AJAX Q1 2012\Bin40\Telerik.Web.UI.dll

Any suggestion? Thank you.
