GeneXus is able to detect the presence of HTML tags written programmatically by the developer in Client-side Events. This approach behaves as the Format property when used to format plain text at design time for certain string properties. However, in this case, GeneXus guesses at runtime which strings wrote by the developer are formatted with HTML tags.
The table below shows the equivalence between HTML tags and Format effect names commonly found in text editors.

In addition, the developer can add a character entity reference to the string. All characters have the following format:
&<name>;
where <name> is the name of the character.

Suppose that, as a developer, you want to alert the user about a certain action. This can be done using a single invocation of Confirm function before the action section code.
Event 'AddToCart'
Composite
Confirm("<font color='#e68a00' size='3'>WARNING</font><br>Are you sure? It can <b>not</b> be <u>undone</u>")
Do 'SubAddToCart'
EndComposite
Endevent
The result of invoking this action is as follows:
Also, the developer is able to format the Form (e.g. promoting some benefit for end users).
In this case, this is achieved with a single line of code.
Event ClientStart
Form.Caption = iif(ProductPrice < 100, "This product has <b>Free <i>shipping</i>!</b>", "Detail")
Endevent
- If the developer uses NewLine Function and <br /> HTML tag in the same text, the first one will be ignored.
Objects: Panel for Smart Devices object, Work With for Smart Devices object
Runtime: Caption property (Form and TabPage) , EmptyGridText property , Msg function, Confirm function
SD Generators: Android
Languages: .NET, Java
This property is available in GeneXus 15
