TagExists Method

Checks if a tag exists in the loaded template.

Syntax

Visual Basic
C#

'Declaration
 
Public Function TagExists( _ 
   ByVal name As String _ 
) As Boolean

public bool TagExists( 
   string name 
)

Parameters

name: The name of tag to check for.

Return Value

true if the tag is found in the template; otherwise false

Remarks

Used for optimizing performance. If the value of a tag is expensive to render, there is no need to execute the code if the template is not going to use the data.

Example

Use TagExists to avoid expensive operations

Visual Basic

Dim t As New Template("MyFolder/MyTemplate.html")
t.SetTag("MyTag", "Hello world!")
If t.TagExists("MyOtherTag") Then
	t.SetTag("MyOtherTag", RunExpensiveOperation())
End If
