Vertical and horizontal scroll bar moves too fast once outside of the Viewport and one is dragging the selection.

RadMap control has an interesting feature in which, while zooming in, if no data is available for a zoom level, the last available image of a lower zoom level is used (scaled up to match the geographical bounds of the image). It would be really useful if the feature was available also while zooming out, allowing users to not have to have data for all zoom levels when using a custom offline provider.

Add an event on the RadVirtualKeyboard class that is raised when a key button is pressed. For example, KeyPressed or something like this. 

Provide option to set if the grouping is case-sensitive

Make the following selection-related methods of the HeatMapDefinition class "protected internal virtual" instead of "internal virtual". 

• IsCellSelected
  
• IsRowSelected
  
• IsColumnSelected
  

This will allow the developer to properly implement also the selection feature in their custom heat map definition code.

Add NoResultsContent and NoResultsContentTemplate properties to the RadMultiColumnComboBox control. 

Add NoResultsContent and NoResultsContentTemplate properties to the RadComboBox control. 

Currently, the width of the category indicator for each item is a fixed size, depending on the design of each theme. Include an API for changing this value.

 RadSpreadsheetSheetSelector add options for disabling the reordering and the editing of the sheets 

Introduce a way to set the modifier key used for multi-column sorting.

LayoutControl uses XamlWriter.Save/XamlReader.Load when custom items/controls are added in its toolbox.
For example:
 LayoutControlHierarchicalNodeProxy radGridToolBoxProxy = new LayoutControlHierarchicalNodeProxy();
 radGridToolBoxProxy.Header = "RadGrid";
 radGridToolBoxProxy.OriginalItemType = typeof(RadGridView);
 radGridToolBoxProxy.OriginalItem = new RadGridView() { };

 this.toolBoxView.NewItems.Add(radGridToolBoxProxy);

OnDrop in LayoutControl, internally a deep copy is created of the object via XamlWriter.Save and  XamlReader.Load. but this has lots of limitations and not every custom control can be successfully restored.

Add event or other API so that user can have control of the creation of the element when drag drop from toolbos is performed.

Add rectangle selection in multiple/extended selection mode just like in Windows Explorer.

Make the MoveSelectionCommandParameter class public so one can easily access its parameters. 

Add input rules and character count limit to the text box: 

 

1. There is no input mask, although the expected pattern is AARRGGBB.
2. Arbitrary and invalid characters can be input (#, +, %, Z, ...).
3. Invalid input is parsed to FF000000, but there is no indication that the input is wrong.
4. Shorter valid sequences, e.g. AB, are parsed, but to FFAB0000, instead of AB000000, which seems unintuitive.
5. Longer sequences exceeding the pattern can be input, although invalid.
6. Entering longer sequences leads to the expansion of the input box even beyond the bounds of the control 

Currently, the there are two frames that happen on property changed that cause the blink. On the first frame, the labels are cleared and the cells are drawn. On the next frame, the labels measure/arrange phase catch up with the cells image drawing and the control is rendered again. Because of this when a cell value is changing at a fast rate (in a timer or similar) and redrawing of the cells is required, a blinking of all texts in the control can be observed.

Currently, the categories in the CategoricalAxis are ordered by the order of their appearance in the plotted data. Allow ordering the categories manually.

Add an API in the chart spline series (like a method override or similar) that allows you to calculate your own set of additional points that render the spline in the chart's spline series.

Implement auto complete for ListDataValidationRule like in Excel.

The RadWatermarkTextBox control updates the position of the floating label when it gets/loses focus. This moves the label to the center or to the top based on whether the control is focused or is losing the focus. This is done via a method that is currently private. 

We can expose the method so that it can be used based on the client's logic.

Currently, the method can be invoked as follows:

Provide a way so one can change the default cell editor with a custom one.
