Code Effects' UI Settings and Appearance

Many visual features of the Rule Editor can be customized as shown below.


Code Effects component comes preloaded with seven CSS themes:

Each theme is implemented in a separate CSS file with the default setting being the Gray theme. Each theme uses the same class names, and each class is prefixed with ce. You can either set the theme programmatically by setting the value of the RuleEditor.Theme property to any member of the ThemeType enumerator...

ruleControl.Theme = CodeEffects.Rule.Common.ThemeType.Green;

... or declaratively, in ASP.NET...

<%@ Register assembly="CodeEffects.Rule"
	namespace="CodeEffects.Rule.Asp" tagprefix="rule" %>

		ID="ruleControl" runat="server"
		Theme="Black" />

... and in MVC:


You can also use your own styles if none of the default CSS files meet your requirements. To do so, first set the RuleEditor.Theme property to ThemeType.None, and then either modify any of Code Effects' theme files or create your own, making sure that all class names used in your file are the same as those used in Code Effects' themes. Finally, include your new file in HTML as you would include any other CSS file.


The Rule Editor also allows you to change the default values of some UI settings. The following list refers to both the ASP.NET and MVC RuleEditor classes.

  • RuleEditor.ShowLineDots. If set to True, displays mid dots at the beginning of each new line inside the rule (you can insert new lines in rules by hitting the Enter key; see the Rule Editor topic for keyboard support details). The default value is False.
  • RuleEditor.ShowMenuOnRightArrowKey. If set to True, displays an appropriate context menu every time the rule author moves the selection from one element to another by pressing the Right Arrow key as (s)he walks through the current rule using the Arrow keys. The default value is True.
  • RuleEditor.ShowMenuOnElementClicked. If set to True, displays a context menu with replacement items every time the rule author clicks the selected rule element. This setting is very useful if you'd like to allow rule authors to edit rules on-the-fly. The default value is True.
  • RuleEditor.ShowDescriptionsOnMouseHover. If set to True, the rule author can hover the cursor over any rule element to view its description (if the value of the Description property of the Field, Action, Method, or Parameter attribute is set for that element). The default value is True.
  • RuleEditor.ShowToolBar. If set to True, displays the Toolbar at the top of the Rule Editor. Toolbar is an important feature of Code Effects component, so make sure to read its topic. The default value is True.
  • RuleEditor.ShowHelpString. If set to True, displays the Help String. The default value is True.
