--- title: "Inserting HTML Dynamically in C#" --- {{% alert color="grey" %}} ## Purpose Summary This page describes inserting HTML dynamically into documents. {{% /alert %}} You can insert HTML to your reports dynamically by using one of the following two options. The first one is using of an expression tag with an `html` switch applied as follows. {{< highlight csharp >}} <<[html_text_expression] -html>> {{< /highlight >}} This option is useful when you need to override formatting of some parts of an expression result, for example, highlight a word with a bold or italic font while staying consistent with styles of a template document. For more information on dynamic HTML insertion using this approach, see “Outputting Expression Results”. The second option for dynamic HTML insertion is using of an `html` tag. An `html` tag denotes a placeholder within a template for an HTML block to be inserted during runtime. Its syntax is defined as follows. {{< highlight csharp >}} <> {{< /highlight >}} **Note** – An `html` tag is forbidden within charts. While building a report, an expression declared within an `html` tag is evaluated and its result as a string is interpreted as an HTML block which content replaces the `html` tag then. In its base usage, an `html` tag behaves exactly the same as an expression tag with an `html` switch applied. In particular, it makes the engine to use corresponding styles of a template document. This makes content of a result document look more consistent. However, you can keep source HTML formatting for content being inserted (to make it look like in a browser) by using a `sourceStyles` switch as shown in the following snippet. {{< highlight csharp >}} <> {{< /highlight >}}
