RadCalendar datepicker not rendering certain class names

Using the following:

<telerik:RadScheduler

ID="RadScheduler"

Skin=""

EnableEmbeddedSkins="false"

EnableEmbeddedBaseStylesheet="false"

MonthView-HeaderDateFormat="MMMM yyyy"

DataKeyField="EventID"

DataSubjectField="Subject"

DataStartField="Start"

DataEndField="End"

ReadOnly="true"

OnClientAppointmentClick="AppointmentClick"

OnNavigationComplete="RadScheduler_NavigationComplete"

runat="server">

</telerik:RadScheduler>

When you click on the datepicker, the pop-up RadCalendar that is rendered does not include classes such as rcHover, rcToday or rcOtherMonth (and possibly others).

Setting the Skin property causes the pop-up calendar to render all the class names as expected.

New tab doesnt display the grid

Hi,

I am trying to open a new radtab on every Search button click. So basically the home page,
opens in a tab which shows a textbox & search button. Then Everytime a user clicks on Search button I need to grab the search result & display in a grid in a new tab. (so if search is clicked 3 times.. there will be 3 additional tabs). How can I achive this functionality?

I was able to create a new tab for each click on button ("search"). The tab opens fine but the grid doesnt display. Not sure where I am going wrong. Can somebody please throw some light if there is any example scenario will be highly appreciated.

During the debug I can see the result set is passsed to the new tab without any issue.

Thank you

RAD rotator issue -not scrolling on single Item bind

Currenlty my Rad rotator configuration is like:

<telerik:RadRotator RotatorType="AutomaticAdvance" Skin="Windows7" ID="rotator1"

runat="server" Height="253px" Width="500px" WrapFrames="true" ItemWidth="98%"

ItemHeight="45px" ScrollDirection="Up"

>  
<ItemTemplate>

</ItemTemplate>

</telerik:RadRotator>

And the CSS class is

.feed

{

overflow: auto;

width: 100%;

height: 100%;

color: #4f6b72;

background-position: center;

}

I am binding the Rotator to a datasource at the backend.

Problem is if the bind has only 1 data.The scrolling is not happening.And if I include more items to the rotator,the scroll is happening?

Is this some default behavior with RAD rotator?

Drag and drop

Hi,

Based on the demo http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/draganddropnodes/defaultcs.aspx, I need to do the same functionality but using a SqlServer database and not using xml files. In other word, I have two SqlServer tables (the same structure) that are displayed using a radtreeview controls, and I need to drag and drop nodes between the two controls and I need that drag and drop to affect the SqlServer tables (not just the controls itself).

Please, I need your help,

Regards,
Bader
