Broken Examples (302 error)

I was looking forward to seeing some changes to the ODataDataSource - Filtering, Sorting and Paging with RadGrid demo after this latest update to fix some glitches. However, this demo and two of the others are now broken and have been down for several days. The service on odata.org seems to have moved. Using Fiddler on the demo page, I get:

RadAutoCompleteBox not displaying correctly and ignoring SelectionMode

Hello - we are using the latest download Version=2013.2.611.40

I am trying to use the RadAutoCompleteBox with the control defined like this:
<telerik:RadAutoCompleteBox ID="racFromUser" runat="server"
                Width="250" DropDownHeight="150" DropDownWidth="250"
                TextSettings-SelectionMode="Single"
                InputType="Token"
>
</telerik:RadAutoCompleteBox>

Issues:
1) The control is not rendering any colors or icons. The box & the dropdown is completly transparent. The dropdown does not hide the junk on the page behind the drop down, so that the list in the drop down get mingled with whatever it is dropping down over making it almost impossible to read the contents of the drop down.

2) The control allows multible items to be slected even though Single selection mode is set in wither token or text mode.

3) In token mode no red x is displayed to delete a token ( the space is still there and hover text still activates )

Disable selected date on RadCalendar?

I'm using SelectedDate from the RadCalendar to display local events from a database using a listview and sqldatasource. It works fine unless I click the same date twice. The SelectedDate is then set to 1/1/0001 12:00:00 AM and I get the error "SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM".

I read that selecting one date causes the previously selected date to become unselected, so I understand why it's happening, I just can't find a workaround.

Is there a way to make the currently selected date inactive (unclickable)? Or, can I check if the user selected the same date?

I tried using Calendar1_SelectionChanged but can't find a way to get the SelectedDate which is really unselected. The FocusedDate is set to today's date, so I can't use it.

<telerik:RadCalendar ID="Calendar1" runat="server" EnableMultiSelect="false" ShowRowHeaders="false" AutoPostBack="true" Skin="MetroTouch" RenderMode="Lightweight"> </telerik:RadCalendar>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MyConnString %>">

<SelectParameters>

<asp:ControlParameter ControlID="Calendar1" Name="calendar1" PropertyName="SelectedDate" />

</SelectParameters>

</asp:SqlDataSource>

[Solved] Colum-widths do not match after row-selection

Hallo,

I recently upgraded from 2012.3.xx.35 to Telerik 2013.2.XX.35 and since then i have a problem with my Grid.
After selecting a row the with of the header and item colums do not match any longer. I think what happens is, is that the header is showing an new "ExpandColumn" whilst the item-part doesnt. Could that be?

The attached screenshot explains what is happeing on row-selection.
please keep in mind that this was working fine when using Telerik 2012.3.xx.35 - dlls.

Searching for a while i found out that it does partially work when setting "UseStaticHeaders" = false and TalbeLayout="Auto". This way the column with of header and item stay equal but are different than before selecting (where the widh is defined delaratively)

please help.
