Certain controls just add bloat to a page.  Like the RadListView is a GREAT control to use inplace of the asp Repeater, but I find I often don't use it (or limit it's use) because it brings down 99.9% useless client scripts.  Most of the time, especially in Sitefinity its a server-side render-only control.  Just used to show data...we don't need ANY client manipulation.

The correct format should be ISO 8601:
([CreateDate] >= '2013-06-22T00.00.00') AND ([CreateDate] <= '2013-06-22T23.59.59'

An ArgumentOutOfRange exception is thrown when using a horizontal barchart with AutoLayout = true.

[ArgumentOutOfRangeException: Length cannot be less than zero.
Parameter name: length]
   System.String.InternalSubStringWithChecks(Int32 startIndex, Int32 length, Boolean fAlwaysCopy) +10695301
   System.String.Substring(Int32 startIndex, Int32 length) +10
   Telerik.Charting.TextBlock.get_VisibleText() +194

Navigate to:

http://localdemos.telerik.com/aspnet-ajax/treelist/examples/databinding/loadondemand/defaultcs.aspx

1) Expand item with ID:2, then items: id:1413, id:1414

2)Expand item id:1

3)Fill Item ID textbox with "303" and Level textbox with "2"

4)Click "ExpandItemToLevel"

5)The icon of item 304 seems like "expanded"(and it should be), however the item is not expanded.

The grid adds the correct Aria-Selected attribute, but JAWS does not work

A sample project for reproducing the issue is attached:

Each of the pages in the ContentUrl properties has an alert("PageName") displayed at pageLoad.

1, Brows the Default.aspx - an alert - page1 occurs

2. Select Level 2 tab, which would load the subTab - Page4 and the "page4" alert should be shown.

Problem : In addition to the "page4" alert - the "page5" alert is raised and the page5.aspx had been loaded along with page4.aspx.

----------------------------------

Workaround:
To workaround this issue, set the PageViewID property of the parent tab to be with the same value as the PageViewID property on the selected child tab.

<telerik:RadTabStrip runat="server" ID="RadTabStrip1" MultiPageID="rmpPages" Width="100%">
    <Tabs>
        <telerik:RadTab Text="Level 1" Selected="true" PageViewID="page1">
            <Tabs>
                <telerik:RadTab Text="Page 1" PageViewID="page1" Selected="true" />
                <telerik:RadTab Text="Page 2" PageViewID="page2" />
                <telerik:RadTab Text="Page 3" PageViewID="page3" />
            </Tabs>
        </telerik:RadTab>
        <telerik:RadTab Text="Level 2" PageViewID="page4">
            <Tabs>
                <telerik:RadTab Text="Page 4" PageViewID="page4" Selected="true" />
                <telerik:RadTab Text="Page 5" PageViewID="page5" />
                <telerik:RadTab Text="Page 6" PageViewID="page6" />
            </Tabs>
        </telerik:RadTab>
    </Tabs>
</telerik:RadTabStrip>

<telerik:RadMultiPage runat="server" ID="rmpPages">

    <telerik:RadPageView runat="server" ID="page1" ContentUrl="page1.aspx" Selected="true" />
