In Q2 2013 the block commands in RadEditor were greatly improved to match desktop editors closely. This means that now block elements like <p> or <div> are required for operations like creating lists, indent/outdent commands.

The default value for the NewLineMode property of the control is BR for historical reasons and thus when the end users press enter they do no longer create elements the block commands can work with. Changing it would be a breaking change, however.
Here is a list with possible implications of changing the default NewLineMode value to P:


Pros:
- The default text editing in modern browsers according to HTML5 specifications (https://dvcs.w3.org/hg/editing/raw-file/tip/editing.html#the-insertparagraph-command) requires that a paragraph is inserted when enter is pressed
- The content generated by the end users by default will integrate better with the improved commands of the control
- Most desktop rich text editing applications (like MS Word) insert a paragraph when enter is pressed


Cons:
- A breaking change in the current control behavior and configuration
- When paragraphs are inserted they will add more margins so the final appearance of the content and the editing process will require more height
- By default, the underlying rich-text editing engine of Firefox uses BR tags and Chrome's - DIV tags

Telerik already provide PDF Viewer for Silverlight, this control is very common used and safe our time to display PDF without using client's browser plugin. 

It will be great this control to be available in ASP.NET, we will not spending IT budget for another controls.

Telerik we know you can do it, this will make you more competitive.

I would like to be able to supply DateTime values for the x axis of an HTMLChart scatter line series to represent a timeline.  Would it be possible to make this easier by having the control plot points plotted based upon the tick count of the value and add support for appropriate label format strings?

In scenarios where the Series are Column/Bar and Positive and Negative values are present, the XAxis labels are overlapped by the Series themselves. Expose an additional Position property for the axis labels that controls their position to Top/Bottom. 

For the time being you can choose either approach:

1) Use a second x-axis that stores only the labels:

a) Category Axis example:
		<script>
			function BottomXAxisLabels() {
				var chart = $find("<%=RadHtmlChart1.ClientID%>").get_kendoWidget();
				var axis = $telerik.$.extend(true, {}, chart.options.categoryAxis);
				axis.line.visible = false;
				chart.setOptions({ categoryAxis: [{}, axis] });
				chart.options.valueAxis.axisCrossingValues = [0, -99999999999];
				chart.redraw();
			}
		</script>
		<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Width="600px" Height="400px">
			<ClientEvents OnLoad="BottomXAxisLabels" />
			<PlotArea>
				<Series>
					<telerik:ColumnSeries Name="Product 1">
						<SeriesItems>
							<telerik:CategorySeriesItem Y="15000" />
							<telerik:CategorySeriesItem Y="-4000" />
							<telerik:CategorySeriesItem Y="10000" />
						</SeriesItems>
					</telerik:ColumnSeries>
				</Series>
				<XAxis>
					<Items>
						<telerik:AxisItem LabelText="1" />
						<telerik:AxisItem LabelText="2" />
						<telerik:AxisItem LabelText="3" />
					</Items>
				</XAxis>
			</PlotArea>
			<ChartTitle Text="Product sales for 2011">
			</ChartTitle>
			<Legend>
				<Appearance Position="Bottom" />
			</Legend>
		</telerik:RadHtmlChart>

b) Numeric axis example:
<script>
			function BottomXAxisLabels() {
				var chart = $find("<%=RadHtmlChart1.ClientID%>").get_kendoWidget();
			    var axis = $telerik.$.extend(true, {}, chart.options.xAxis);
				axis.line.visible = false;
				chart.setOptions({ xAxis: [{ labels: { visible: false }}, axis] });
				chart.options.yAxis.axisCrossingValues = [0, -99999999999];
				chart.redraw();
			}
		</script>
		<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Width="600px" Height="400px">
			<ClientEvents OnLoad="BottomXAxisLabels" />
			<PlotArea>
				<Series>
					<telerik:ScatterLineSeries Name="Product 1">
						<SeriesItems>
							<telerik:ScatterSeriesItem Y="15000" X="5" />
							<telerik:ScatterSeriesItem Y="-4000" X="6" />
							<telerik:ScatterSeriesItem Y="10000" X="7"/>
						</SeriesItems>
					</telerik:ScatterLineSeries>
				</Series>
			</PlotArea>
			<ChartTitle Text="Product sales for 2011">
			</ChartTitle>
			<Legend>
				<Appearance Position="Bottom" />
			</Legend>
		</telerik:RadHtmlChart>

2) Use the TextStyle property of the RadHtmlChart , in order to set higher margin for the XAxis labels. For example:

		<telerik:RadHtmlChart ID="RadHtmlChart1" runat="server" Width="600px" Height="400px">
			<PlotArea>
				<Series>
					<telerik:ColumnSeries Name="Product 1">
						<SeriesItems>
							<telerik:CategorySeriesItem Y="15000" />
							<telerik:CategorySeriesItem Y="-4000" />
							<telerik:CategorySeriesItem Y="10000" />
						</SeriesItems>
					</telerik:ColumnSeries>
				</Series>
				<XAxis>
					<LabelsAppearance>
						<TextStyle Margin="135 0 0 0" />
					</LabelsAppearance>
					<Items>
						<telerik:AxisItem LabelText="item1" />
						<telerik:AxisItem LabelText="item2" />
						<telerik:AxisItem LabelText="item3" />
					</Items>
				</XAxis>
			</PlotArea>
		</telerik:RadHtmlChart>

Note: Labels margin and chart's PlotArea height are inversely proportional - the higher the margin is the lower the chart's PlotArea height will be. This resizing is needed, in order for the chart's main dimensions to be kept.

We have created a KB article where a possible approach to achieve image resizing before the upload is suggested. You can find it at https://www.telerik.com/support/kb/aspnet-ajax/upload-(async)/details/resize-images-client-side-with-html5-before-uploading-with-radasyncupload

The article describes a straightforward way on how to change the uploaded image dimensions. You can further improve and modify the logic in the _uploadFile function to allow the user to define the new dimensions or use a tool to allow the users to modify the image.

Update from 4 Oct 2017: You can find a sample implementation of a CDN fallback in the following code library project: http://www.telerik.com/support/code-library/cdn-fallback



You can try implementing a fallback similar to the approach from the links below, but check for the window.$telerik variable and initiate a postback to change the web.config or the concrete page's properties to avoid the CDN.

You can find a sample implementation attached below.

- http://www.hanselman.com/blog/CDNsFailButYourScriptsDontHaveToFallbackFromCDNToLocalJQuery.aspx
- http://docs.telerik.com/kendo-ui/intro/installation/cdn-service#refer-kendo-ui-from-cdn-with-local-script-fallbacks

Alternatively, use a custom CDN of your choice that will be better for your case/have better uptime than Amazon CloudFront: http://docs.telerik.com/devtools/aspnet-ajax/controls/scriptmanager/cdn-support/custom-cdn-provider

Take a look at www.pasteboard.co/. It works fine in all major browsers except for IE.

Image content is inserted right in the image tag like: <IMG SRC="data:image/png;base64,...">, and that's exactly what we need. We don't even need the pasted images to be uploaded to the server side.

It seems www.pasteboard.co/ doesn't rely on the canvas element. You can remove it, and everything will work fine. Please see http://screencast.com/t/8IHQfHvq0e.

Also please see www.snag.gy. It doesn't contain a canvas, but still works well.

You can also take a look at strd6.com/2011/09/html5-javascript-pasting-image-data-in-chrome. It doesn't look great because it works in Chrome only. But still it works in Chrome.

As of R1 2017 you can use the stackTotal property of the labels:
https://docs.telerik.com/kendo-ui/controls/charts/how-to/various/show-stack-total

old information

For the time being this can be achieved by creating an additional bar/column series with the following settings:

-series items are set with insignificantly small values (e.g. 0.001)

-the name property of the series is not specified, so that it is not visible in the legend

-the color of the series matches the color of the plot area, so that the series items and the legend of the series are not visible

-clienttemplates for the labels of this series is used in order to sum up the grand total and display it

An example on the described scenario can be found in the http://www.telerik.com/support/kb/aspnet-ajax/chart-%28html5%29/details/displaying-grand-total-in-stacked-series-labels-and-pie-series-legend KB article

UploadedFiles collection needs to be available across post backs.

You can configure the confirm dialog through a ConfirmText property that defines the confirmation text. The boolean result can be exposed in the arguments of the click event. If there is a RadWindowManager on the same page a radconfirm should be used otherwise - the browser one.

For the time being the functionality can be achieved manually as illustrated in this demo - http://demos.telerik.com/aspnet-ajax/button/examples/confirm/defaultcs.aspx

Based on customer feedback:

A control / tool to layout forms in a professional, quick and consistent manner

In it's current state the RadButton only emulates the looks of a SplitButton, but not the behaviour.

In my point of view, such control should prove valuable to customers. More over, there is a growing need of base controls since we already have a at least three such implementations.

A RadSplitButton should be the base (or it's base should be the base) for all control specific implementations of a split button

Support for NavigateUrl as implemented in other controls like RadLightBox. The idea is to redirect to a specific URL when clicking on an image.

provide htmlchart in 2D/3D

Provide the ability for the developer to configure the grid so that the Group By box appears _below_ the CommandItem

It would be useful for the header cell for Sort-able columns to display an indication that the column can be sorted.  This is useful to users when not all columns are sort-able, so they know which header cells will trigger resorting.

Elsewhere in our application, we use a double headed arrow icon to indicate use can click on header to resort on the column; the app displays the up or down arrow indicating when sort order is active.

Suggest adding a third Sort-Image-URL attribute to specify an image to use when column is not sorted ascending or descending.

At present, best I can do declaratively (w/o custom coding) is the set one of the HeaderStyle-Font properties (for example the HeaderStyle-Font-Underline) to provide a visual indication that column is sort-able.
