How to create a custom theme for shapes in DiagramDesignerControl

Shapes in the Diagram control are colored according to an applied theme. To create a custom theme, add a resource dictionary into your application and add the Theme element into it. 
Each theme should contain a color palette which defines main colors used in a theme. To specify a color palette, add the ColorPalette element into Theme. 

To specify how colors are used in a theme, set the Theme.Effects property. This property accepts the EffectCollection object. EffectCollection defines colors shown in the following gallery:


EffectCollection has the following properties:
-ThemeEffects. Influences colors in the "Theme Styles" group.
-VariantEffects. Influences colors in the "Variant Styles" group. When a shape is created its default color scheme is taken from this group.
-ConnectorEffects. Influences connector colors.
 
To register a custom theme, use the ThemeRegistrator.RegisterThemes method.

How to select/deselect row by clicking it and prevent a selection of other rows from being cleared

This example demonstrates how to create a helper class that allows you to select rows as if the CTRL button is pressed. I.e. rows selection is not cleared when a particular row is clicked. Only a clicked row's state is changed.

Outstanding!  Select "MultiSelectionHelper.cs" in the first combo below, see bottom section.  CalcHitInfo(), InvertRowSelection(), GetMouseArgs(e).Handled = true.  Thank you!

I'd like to add that with v15, i've been able to obtain the desired result with only the RowCellCkick event and the following:

gridView.InvertRowSelection(e.RowHandle);  
e.Handled = true;

dxDateBox - How to disable particular dates in the calendar

Currently, dxDateBox does not provide API that allows you to disable specific dates: T260958: dxDateBox - Is it possible to disable dates?. However, it is possible to implement a workaround. The main idea is to select elements with necessary content by using jQuery and disable them. To get the information about a particular calendar cell, use the "aria-label" attribute (this is the most convenient way to determine the day of the week for a particular cell) or any other HTML attribute that meets your requirements (for instance, "data-value").

 

To determine the appropriate attribute, inspect the elements in the calendar like it is described in the K18570: How to inspect CSS rules article.
